COMMISSION REGULATION (EU) 2017/2400

29.12.2017 | EN | Official Journal of the European Union | L 349/1 ---|---|---|--- * * * COMMISSION REGULATION (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information and amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC (1), and in particular Article 4(3) and Article 5(4)(e) thereof, Having regard to Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive) (2), and in particular Article 39(7) thereof, Whereas: (1) | Regulation (EC) No 595/2009 is one of the separate regulatory acts under the type-approval procedure laid down by Directive 2007/46/EC. It empowers the Commission to adopt measures relating to CO2 emissions and fuel consumption of heavy duty vehicles. The present Regulation aims at establishing measures for obtaining accurate information on CO2 emissions and fuel consumption of new heavy-duty vehicles placed on the Union market. ---|--- (2) | Directive 2007/46/EC sets out the necessary requirements for the purpose of a whole vehicle type-approval. ---|--- (3) | Commission Regulation (EU) No 582/2011 (3) sets out requirements for the approval of heavy-duty vehicles with regard to emissions and access to vehicle repair and maintenance information. Measures for the determination of CO2 emissions and fuel consumption of new heavy-duty vehicles should be part of the type-approval system instituted by this Regulation. A licence to perform simulations to establish CO2 emissions and fuel consumption of a vehicle will be required to obtain the approvals mentioned above. ---|--- (4) | Emissions from lorries, buses and coaches, which are the most widely representative categories of heavy-duty vehicles, currently represent around 25 % of road transport CO2 emissions and are expected to increase even further in the future. In order to reach the target of a 60 % reduction of CO2 emissions from transport by 2050, effective measures to curb emissions from heavy-duty vehicles need to be introduced. ---|--- (5) | Until now, no common method has been laid down by Union legislation to measure CO2 emissions and fuel consumption of heavy-duty vehicles, rendering it impossible to objectively compare performance of vehicles or to introduce measures, whether on the Union or national level, that would encourage the introduction of more energy-efficient vehicles. As a consequence, there has been no transparency in the market as regards the energy-efficiency of heavy-duty vehicles. ---|--- (6) | The heavy-duty vehicle sector is very diversified, with a significant number of different vehicle types and models as well as with a high degree of customisation. The Commission has conducted an in-depth analysis of the available options to measure CO2 emissions and fuel consumption of those vehicles and concluded that in order to obtain unique data for each produced vehicle at the lowest cost, CO2 emissions and fuel consumption of heavy-duty vehicles should be determined using simulation software. ---|--- (7) | In order to reflect the diversity of the sector, heavy-duty vehicles should be divided into groups of vehicles with a similar axle configuration, chassis configuration and technically permissible maximum laden mass. Those parameters define the purpose of a vehicle and should therefore determine the set of test cycles used for the purpose of the simulation. ---|--- (8) | Since there is no software available on the market to meet the requirements necessary for the purposes of the assessment of CO2 emissions and fuel consumption of heavy-duty vehicles, the Commission should develop dedicated software to be used for those purposes. ---|--- (9) | That software should be publically available, open-source, downloadable and executable. It should include a simulation tool for the calculation of CO2 emissions and fuel consumption of specific heavy-duty vehicles. The tool should be conceived to use, as input, the data reflecting the characteristics of the components, separate technical units and systems which have a significant impact on the CO2 emissions and fuel consumption of heavy-duty vehicles – engine, gearbox and additional driveline components, axles, tyres, aerodynamics and auxiliaries. The software should also include pre-processing tools to be used for the verification and pre-processing of the simulation tool input data relating to the engine and vehicle air drag, as well as a hashing tool to be used for the encryption of the simulation tool input and output files. ---|--- (10) | In order to enable a realistic assessment, the simulation tool should be equipped with a number of functionalities allowing for a simulation of vehicles with different payloads and fuels over specific test cycles assigned to a vehicle depending on its application. ---|--- (11) | Recognizing the importance of the proper functioning of the software for the correct determination of vehicles' CO2 emissions and fuel consumption and of keeping up with technological progress, the Commission should maintain the software and update it whenever necessary. ---|--- (12) | The simulations should be performed by vehicle manufacturers before registration, sale or entry into service of a new vehicle in the Union. Provisions should also be put in place for the licence of the vehicle manufacturers' processes for calculation of the CO2 emissions and fuel consumption of vehicles. The processes of handling and application of data by the vehicle manufacturers for the purposes of calculation of the CO2 emissions and fuel consumption of vehicles using the simulation tool should be assessed and closely monitored by the approval authorities in order to ensure that the simulations are conducted in a correct manner. Provisions should therefore be put in place requiring vehicle manufacturers to acquire a licence for the operation of the simulation tool. ---|--- (13) | The CO2 emissions and fuel consumption related properties of the components, separate technical units and systems having a significant impact on the CO2 emissions and fuel consumption of heavy-duty vehicles should be used as input for the simulation tool. ---|--- (14) | In order to reflect the specificities of the individual components, separate technical units and systems and to allow for a more precise determination of their CO2 emissions and fuel consumption related properties, provisions for the certification of such properties on the basis of testing should be set out. ---|--- (15) | For the purpose of limiting the costs of the certification, manufacturers should have the possibility to group into families components, separate technical units and systems with similar design and CO2 emission and fuel consumption characteristics. One component, separate technical unit or system per family with the least favourable characteristics as regards CO2 emissions and fuel consumption within that family should be tested and its results should apply to the entire family. ---|--- (16) | The costs related to testing may constitute a significant obstacle in particular to companies manufacturing components, separate technical units or systems in small numbers. In order to provide an economically viable alternative to certification, standard values should be set out for certain components, separate technical units and systems with the possibility of using those values instead of the certified values determined on the basis of testing. Standard values should, however, be set out in a way to encourage suppliers of components, separate technical units and systems to apply for certification. ---|--- (17) | In order to ensure that the results relating to CO2 emissions and fuel consumption declared by the suppliers of components, separate technical units and systems as well as vehicle manufacturers are correct, provisions for verifying and ensuring the conformity of the simulation tool operation as well as of the CO2 emissions and fuel consumption related properties of the relevant components, separate technical units and systems should be set out. ---|--- (18) | In order to ensure sufficient lead time for the national authorities and the industry, the obligation to determine and declare CO2 emissions and fuel consumption of new vehicles should be implemented gradually for different vehicle groups starting with the vehicles which are the biggest contributors to CO2 emissions of the heavy-duty sector. ---|--- (19) | The provisions set out in this Regulation form part of the framework established by Directive 2007/46/EC and complement the provisions for type approval with regard to emissions and vehicle repair and maintenance information laid down in Regulation (EU) No 582/2011. To establish a clear relationship between those provisions and this Regulation, Directive 2007/46/EC and Regulation (EU) No 582/2011 should be amended accordingly. ---|--- (20) | The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee Motor Vehicles, ---|--- HAS ADOPTED THIS REGULATION: CHAPTER 1 GENERAL PROVISIONS Article 1 Subject matter This Regulation complements the legal framework for the type-approval of motor vehicles and engines with regard to emissions and vehicle repair and maintenance information established by Regulation (EU) No 582/2011 by laying down the rules for issuing licences to operate a simulation tool with a view to determining CO2 emissions and fuel consumption of new vehicles to be sold, registered or put into service in the Union and for operating that simulation tool and declaring the CO2 emissions and fuel consumption values thus determined.

Introduction The engine test procedure described in this Annex shall produce input data relating to engines for the simulation tool. 2\. Definitions For the purposes of this Annex the definitions according to UN/ECE Regulation 49 Rev.06 and, in addition to these, the following definitions shall apply: (1) | ‘engine CO2-family’ means a manufacturer's grouping of engines, as defined in paragraph 1 of Appendix 3; ---|--- (2) | ‘CO2-parent engine’ means an engine selected from an engine CO2-family as specified in Appendix 3; ---|--- (3) | ‘NCV’ means net calorific value of a fuel as specified in paragraph 3.2; ---|--- (4) | ‘specific mass emissions’ means the total mass emissions divided by the total engine work over a defined period expressed in g/kWh; ---|--- (5) | ‘specific fuel consumption’ means the total fuel consumption divided by the total engine work over a defined period expressed in g/kWh; ---|--- (6) | ‘FCMC’ means fuel consumption mapping cycle; ---|--- (7) | ‘Full load’ means the delivered engine torque/power at a certain engine speed when the engine is operated at maximum operator demand. ---|--- The definitions in paragraphs 3.1.5 and 3.1.6. of Annex 4 to UN/ECE Regulation 49 Rev.06 shall not apply. 3\. General requirements The calibration laboratory facilities shall comply with the requirements of either ISO/TS 16949, ISO 9000 series or ISO/IEC 17025. All laboratory reference measurement equipment, used for calibration and/or verification, shall be traceable to national or international standards. Engines shall be grouped into engine CO2-families defined in accordance with Appendix 3. Paragraph 4.1 explains which testruns shall be performed for the purpose of certification of one specific engine CO2-family. 3.1 Test conditions All testruns performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3 to this Annex shall be conducted on the same physical engine and without any changes to the setup of the engine dynamometer and the engine system, apart from the exceptions defined in paragraph 4.2 and Appendix 3. 3.1.1 Laboratory test conditions The tests shall be conducted under ambient conditions meeting the following conditions over the whole testrun: (1) | The parameter fa describing the laboratory test conditions, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06, shall be within the following limits: 0,96 ≤ fa ≤ 1,04. ---|--- (2) | The absolute temperature (Ta) of the engine intake air expressed in Kelvin, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06 shall be within the following limits: 283 K ≤ Ta ≤ 303 K. ---|--- (3) | The atmospheric pressure expressed in kPa, determined in accordance with paragraph 6.1 of Annex 4 to UN/ECE Regulation 49 Rev.06 shall be within the following limits: 90 kPa ≤ ps ≤ 102 kPa. ---|--- If tests are performed in test cells that are able to simulate barometric conditions other than those existing in the atmosphere at the specific test site, the applicable fa value shall be determined with the simulated values of atmospheric pressure by the conditioning system. The same reference value for the simulated atmospheric pressure shall be used for the intake air and exhaust path and all other relevant engine systems. The actual value of the simulated atmospheric pressure for the intake air and exhaust path and all other relevant engine systems shall be within the limits specified in subpoint (3). In cases where the ambient pressure in the atmosphere at the specific test site exceeds the upper limit of 102 kPa, tests in accordance with this Annex may still be performed. In this case tests shall be performed with the specific ambient air pressure in the atmosphere. In cases where the test cell has the ability to control temperature, pressure and/or humidity of engine intake air independent of the atmospheric conditions the same settings for those parameters shall be used for all testruns performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3 to this Annex. 3.1.2 Engine installation The test engine shall be installed in accordance with paragraphs 6.3 to 6.6 of Annex 4 to UN/ECE Regulation 49 Rev.06. If auxiliaries/equipment necessary for operating the engine system are not installed as required in accordance with paragraph 6.3 of Annex 4 to UN/ECE Regulation 49 Rev.06, all measured engine torque values shall be corrected for the power required for driving these components for the purpose of this Annex in accordance with paragraph 6.3 of Annex 4 to UN/ECE Regulation 49 Rev.06. The power consumption of the following engine components resulting in the engine torque required for driving these engine components shall be determined in accordance with Appendix 5 to this Annex: (1) | fan ---|--- (2) | electrically powered auxiliaries/equipment necessary for operating the engine system ---|--- 3.1.3 Crankcase emissions In the case of a closed crankcase, the manufacturer shall ensure that the engine's ventilation system does not permit the emission of any crankcase gases into the atmosphere. If the crankcase is of an open type, the emissions shall be measured and added to the tailpipe emissions, following the provisions set out in paragraph 6.10. of Annex 4 to UN/ECE Regulation 49 Rev.06. 3.1.4 Engines with charge air-cooling During all testruns the charge air cooling system used on the test bed shall be operated under conditions which are representative for in-vehicle application at reference ambient conditions. The reference ambient conditions are defined as 293 K for air temperature and 101,3 kPa for pressure. The laboratory charge air cooling for tests according to this regulation should comply with the provisions specified in paragraph 6.2 of Annex 4 to UN/ECE Regulation 49 Rev.06. 3.1.5 Engine cooling system (1) | During all testruns the engine cooling system used on the test bed shall be operated under conditions which are representative for in-vehicle application at reference ambient conditions. The reference ambient conditions are defined as 293 K for air temperature and 101,3 kPa for pressure. ---|--- (2) | The engine cooling system should be equipped with thermostats according to the manufacturer specification for vehicle installation. If either a non-operational thermostat is installed or no thermostat is used, subpoint (3) shall apply. The setting of the cooling system shall be performed in accordance with subpoint (4). ---|--- (3) | If no thermostat is used or a non-operational thermostat is installed, the test bed system shall reflect the behavior of the thermostat under all test conditions. The setting of the cooling system shall be performed in accordance with subpoint (4). ---|--- (4) | The engine coolant flow rate (or alternatively the pressure differential across the engine side of the heat exchanger) and the engine coolant temperature shall be set to a value representative for in-vehicle application at reference ambient conditions when the engine is operated at rated speed and full load with the engine thermostat in fully open position. This setting defines the coolant reference temperature. For all testruns performed for the purpose of certification of one specific engine within one engine CO2-family, the cooling system setting shall not be changed, neither on the engine side nor on the test bed side of the cooling system. The temperature of the test bed side cooling medium should be kept resonably constant by good engineering judgement. The cooling medium on the test bed side of the heat exchanger shall not exceed the nominal thermostat opening temperatur downstream of the heat exchanger. ---|--- (5) | For all testruns performed for the purpose of certification of one specific engine within one engine CO2-family the engine coolant temperature shall be maintained between the nominal value of the thermostat opening temperature declared by the manufacturer and the coolant reference temperature in accordance with subpoint (4) as soon as the engine coolant has reached the declared thermostat opening temperature after engine cold start. ---|--- (6) | For the WHTC coldstart test performed in accordance with paragraph 4.3.3, the specific initial conditions are specified in paragraphs 7.6.1. and 7.6.2 of Annex 4 to UN/ECE Regulation 49 Rev.06. If simulation of the thermostat behaviour in accordance with subpoint (3) is applied, there shall be no coolant flow across the heat exchanger as long as the engine coolant has not reached the declared nominal thermostat opening temperature after cold start. ---|--- 3.2 Fuels The respective reference fuel for the engine systems under test shall be selected from the fuel types listed in Table 1. The fuel properties of the reference fuels listed in Table 1 shall be those specified in Annex IX to Commission Regulation (EU) No 582/2011. To ensure that the same fuel is used for all testruns performed for the purpose of certification of one specific engine CO2-family no refill of the tank or switch to another tank supplying the engine system shall occur. Exceptionally a refill or switch may be allowed if it can be ensured that the replacement fuel has exactly the same properties as the fuel used before (same production batch). The NCV for the fuel used shall be determined by two separate measurements in accordance with the respective standards for each fuel type defined in Table 1. The two separate measurements shall be performed by two different labs independent from the manufacturer applying for certification. The lab performing the measurements shall comply with the requirements of ISO/IEC 17025. The approval authority shall ensure that the fuel sample used for determination of the NCV is taken from the batch of fuel used for all testruns. If the two separate values for the NCV are deviating by more than 440 Joule per gram fuel, the values determined shall be void and the measurement campaign shall be repeated. The mean value of the two separate NCV that are not deviating by more than 440 Joule per gram fuel shall be documented in MJ/kg rounded to 3 places to the right of the decimal point in accordance with ASTM E 29-06. For gas fuels the standards for determining the NCV according to Table 1 contain the calculation of the calorific value based on the fuel composition. The gas fuel composition for determining the NCV shall be taken from the analysis of the reference gas fuel batch used for the certification tests. For the determination of the gas fuel composition used for determining the NCV only one single analysis by a lab independent from the manufacturer applying for certification shall be performed. For gas fuels the NCV shall be determined based on this single analysis instead of a mean value of two separate measurements. Table 1 Reference fuels for testing Fuel type / engine type | Reference fuel type | Standard used for determination of NCV ---|---|--- Diesel / CI | B7 | at least ASTM D240 or DIN 59100-1 (ASTM D4809 is recommended) Ethanol / CI | ED95 | at least ASTM D240 or DIN 59100-1 (ASTM D4809 is recommended) Petrol / PI | E10 | at least ASTM D240 or DIN 59100-1 (ASTM D4809 is recommended) Ethanol / PI | E85 | at least ASTM D240 or DIN 59100-1 (ASTM D4809 is recommended) LPG / PI | LPG Fuel B | ASTM 3588 or DIN 51612 Natural Gas / PI | G25 | ISO 6976 or ASTM 3588 3.3 Lubricants The lubricating oil for all testruns performed in accordance with this Annex shall be a commercially available oil with unrestricted manufacturer approval under normal in-service conditions as defined in paragraph 4.2 of Annex 8 to UN/ECE Regulation 49 Rev.06. Lubricants for which the usage is restricted to certain special operation conditions of the engine system or having an unusually short oil change interval shall not be used for the purpose of testruns in accordance with this Annex. The commercially available oil shall not be modified by any means and no additives shall be added. All testruns performed for the purpose of certification of the CO2 emissions and fuel consumption related properties of one specific engine CO2-family shall be performed with the same type of lubricating oil. 3.4 Fuel flow measurement system All fuel flows consumed by the whole engine system shall be captured by the fuel flow measurement system. Additional fuel flows not directly supplied to the combustion process in the engine cylinders shall be included in the fuel flow signal for all testruns performed. Additional fuel injectors (e.g. cold start devices) not necessary for the operation of the engine system shall be disconnected from the fuel supply line during all testruns performed. 3.5 Measurement equipment specifications The measurement equipment shall meet the requirements of paragraph 9 of Annex 4 to UN/ECE Regulation 49 Rev.06. Notwithstanding the requirements defined in paragraph 9 of Annex 4 to UN/ECE Regulation 49 Rev.06, the measurement systems listed in Table 2 shall meet the limits defined in Table 2.

At least 10 reference values between xmin and the ‘max calibration’ value defined in accordance with paragraph 3.5 shall be introduced to the measurement system and the response of the measurement system shall be recorded as measured value. For the linearity verification the measured values shall be compared to the reference values by using a least squares linear regression in accordance with paragraph A.3.2 of Appendix 3 to Annex 4 to UN/ECE Regulation 49 Rev.06. 4\.

Testing procedure All measurement data shall be determined in accordance with Annex 4 to UN/ECE Regulation 49 Rev.06, unless stated otherwise in this Annex. 4.1 Overview of testruns to be performed Table 3 gives an overview of all testruns to be performed for the purpose of certification of one specific engine CO2-family defined in accordance with Appendix 3. The fuel consumption mapping cycle in accordance with paragraph 4.3.5 and the recording of the engine motoring curve in accordance with paragraph 4.3.2 shall be omitted for all other engines except the CO2-parent engine of the engine CO2-family. In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the fuel consumption mapping cycle in accordance with paragraph 4.3.5 and the recording of the engine motoring curve in accordance with paragraph 4.3.2 shall be performed additionally for that specific engine. Table 3 Overview of testruns to be performed Testrun | Reference to paragraph | Required to be run for CO2-parent engine | Required to be run for other engines within CO2-family ---|---|---|--- Engine full load curve | 4.3.1 | yes | yes Engine motoring curve | 4.3.2 | yes | no WHTC test | 4.3.3 | yes | yes WHSC test | 4.3.4 | yes | yes Fuel consumption mapping cycle | 4.3.5 | yes | no 4.2 Allowed changes to the engine system Changing of the target value for the engine idle speed controller to a lower value in the electronic control unit of the engine shall be allowed for all testruns in which idle operation occurs, in order to prevent interference between the engine idle speed controller and the test bed speed controller. 4.3 Testruns 4.3.1 Engine full load curve The engine full load curve shall be recorded in accordance with paragraphs 7.4.1. to 7.4.5. of Annex 4 to UN/ECE Regulation 49 Rev.06. 4.3.2 Engine motoring curve The recording of the engine motoring curve in accordance with this paragraph shall be omitted for all other engines except the CO2-parent engine of the engine CO2-family defined in accordance with Appendix 3. In accordance with paragraph 6.1.3 the engine motoring curve recorded for the CO2-parent engine of the engine CO2-family shall also be applicable to all engines within the same engine CO2-family. In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the recording of the engine motoring curve shall be performed additionally for that specific engine. The engine motoring curve shall be recorded in accordance with option (b) in paragraph 7.4.7. of Annex 4 to UN/ECE Regulation 49 Rev.06. This test shall determine the negative torque required to motor the engine between maximum and minimum mapping speed with minimum operator demand. The test shall be continued directly after the full load curve mapping according to paragraph 4.3.1. At the request of the manufacturer, the motoring curve may be recorded separately. In this case the engine oil temperature at the end of the full load curve testrun performed in accordance with paragraph 4.3.1 shall be recorded and the manufacturer shall prove to the satisfaction of the an approval authority, that the engine oil temperature at the starting point of the motoring curve meets the aforementioned temperature within ± 2 K. At the start of the testrun for the engine motoring curve the engine shall be operated with minimum operator demand at maximum mapping speed defined in paragraph 7.4.3. of Annex 4 to UN/ECE Regulation 49 Rev.06.

General provisions 1.1 Conformity of CO2 emissions and fuel consumption related properties shall be checked on the basis of the description in the certificates set out in Appendix 1 to this Annex and on the basis of the description in the information document set out in Appendix 2 to this Annex. 1.2 If an engine certificate has had one or more extensions, the tests shall be carried out on the engines described in the information package relating to the relevant extension. 1.3 All engines subject to tests shall be taken from the series production meeting the selection criteria according to paragraph 3 of this Appendix. 1.4 The tests may be conducted with the applicable market fuels. However, at the manufacturer's request, the reference fuels specified in paragraph 3.2 may be used. 1.5 If tests for the purpose of conformity of CO2 emissions and fuel consumption related properties of gas engines (natural gas, LPG) are conducted with market fuels the engine manufacturer shall demonstrate to the approval authority the appropriate determination of the gas fuel composition for the determination of the NCV according to paragraph 4 of this Appendix by good engineering judgement. 2\. Number of engines and engine CO2-families to be tested 2.1 0,05 percent of all engines produced in the past production year within the scope of this regulation shall represent the basis to derive the number of engine CO2-families and number of engines within those CO2-families to be tested annually for verifying conformity of the certified CO2 emissions and fuel consumption related properties. The resulting figure of 0,05 percent of relevant engines shall be rounded to the nearest whole number. This result shall be called nCOP,base. 2.2 Notwithstanding the provisions in point 2.1, a minimum number of 30 shall be used for nCOP,base. 2.3 The resulting figure for nCOP,base determined in accordance with points 2.1 and 2.2 of this Appendix shall be divided by 10 and the result rounded to the nearest whole number in order to determine the number of engine CO2-families to be tested annually, nCOP,fam, for verifying conformity of the certified CO2 emissions and fuel consumption related properties. 2.4 In the case that a manufacturer has less CO2-families than nCOP,fam determined in accordance with point 2.3, the number of CO2-families to be tested, nCOP,fam, shall be defined by the total number of CO2-families of the manufacturer. 3\. Selection of engine CO2-families to be tested From the number of engine CO2-families to be tested determined in accordance with paragraph 2 of this Appendix, the first two CO2-families shall be those with the highest production volumes. The remaining number of engine CO2-families to be tested shall be randomly selected from all existing engine CO2-families and shall be agreed between the manufacturer and the approval authority. 4\. Testrun to be performed The minimum number of engines to be tested for each engine CO2-family, nCOP,min, shall be determined by dividing nCOP,base by nCOP,fam, both values determined in accordance with point 2.

For each of the engine CO2-families determined in accordance with paragraph 3 of this Appendix a minimum number of nCOP,min engines within that family shall be tested in order to reach a pass decision in accordance with paragraph 9 of this Appendix. The number of testruns to be performed within an engine CO2-family shall be randomly assigned to the different engines within that CO2-family and this assignment shall be agreed between the manufacturer and the approval authority. Conformity of the certified CO2 emissions and fuel consumption related properties shall be verified by testing the engines in the WHSC test in accordance with paragraph 4.3.4. All boundary conditions as specified in this Annex for the certification testing shall apply, except for the following: (1) | The laboratory test conditions in accordance with paragraph 3.1.1 of this Annex. The conditions in accordance with paragraph 3.1.1 are recommended and shall not be mandatory.

Torque losses resulting from the drive mechanism between the transmission and those components can be neglected. 2\. Definitions For the purposes of this Annex the following definitions shall apply: (1) | ‘Transfer case’ means a device that splits the engine power of a vehicle and directs it to the front and rear drive axles. It is mounted behind the transmission and both front and rear drive shafts connect to it. It comprises either a gearwheel set or a chain drive system in which the power is distributed from the transmission to the axles. The transfer case will typically have the ability to shift between standard drive mode (front or rear wheel drive), high range traction mode (front and rear wheel drive), low range traction mode and neutral; ---|--- (2) | ‘Gear ratio’ means the forward gear ratio of the speed of the input shaft (towards prime mover) to the speed of the output shaft (towards driven wheels) without slip (i = nin/nout ); ---|--- (3) | ‘Ratio coverage’ means the ratio of the largest to the smallest forward gear ratios in a transmission: φtot = imax/imin ; ---|--- (4) | ‘Compound transmission’ means a transmission, with a large number of forward gears and/or large ratio coverage, composed of sub-transmissions, which are combined to use most power-transferring parts in several forward gears; ---|--- (5) | ‘Main section’ means the sub-transmission that has the largest number of forward gears in a compound transmission; ---|--- (6) | ‘Range section’ means a sub-transmission normally in series connection with the main section in a compound transmission. A range section usually has two shiftable forward gears. The lower forward gears of the complete transmission are embodied using the low range gear. The higher gears are embodied using the high range gear; ---|--- (7) | ‘Splitter’ means a design that splits the main section gears in two (usually) variants, low- and high split gears, whose gear ratios are close compared to the ratio coverage of the transmission. A splitter can be a separate sub-transmission, an add-on device, integrated with the main section or a combination thereof; ---|--- (8) | ‘Tooth clutch’ means a clutch where torque is transferred mainly by normal forces between mating teeth. A tooth clutch can either be engaged or disengaged.

A friction clutch can transmit torque while slipping, it can thereby (but does not have to) be operated at start-offs and at powershifts (retained power transfer during a gear shift); ---|--- (11) | ‘Synchroniser’ means a type of tooth clutch where a friction device is used to equalise the speeds of the rotating parts to be engaged; ---|--- (12) | ‘Gear mesh efficiency’ means the ratio of output power to input power when transmitted in a forward gear mesh with relative motion; ---|--- (13) | ‘Crawler gear’ means a low forward gear (with speed reduction ratio that is larger than for the non-crawler gears) that is designed to be used infrequently, e.g., at low-speed manoeuvres or occasional up-hill start-offs; ---|--- (14) | ‘Power take-off (PTO)’ means a device on a transmission or an engine to which an auxiliary driven device, e.g., a hydraulic pump, can be connected; ---|--- (15) | ‘Power take-off drive mechanism’ means a device in a transmission that allows the installation of a power take-off (PTO); ---|--- (16) | ‘Lock-up clutch’ means a friction clutch in a hydrodynamic torque converter; it can connect the input and output sides, thereby eliminating the slip; ---|--- (17) | ‘Start-off clutch’ means a clutch that adapts speed between engine and driven wheels when the vehicle starts off. The start-off clutch is usually located between engine and transmission; ---|--- (18) | ‘Synchronised Manual Transmission (SMT)’ means a manually operated transmission with two or more selectable speed ratios that are obtained using synchronisers. Ratio changing is normally achieved during a temporary disconnection of the transmission from the engine using a clutch (usually the vehicle start-off clutch); ---|--- (19) | ‘Automated Manual Transmission or Automatic Mechanically-engaged Transmission (AMT)’ means an automatically shifting transmission with two or more selectable speed ratios that are obtained using tooth clutches (un-/synchronised). Ratio changing is achieved during a temporary disconnection of the transmission from the engine. The ratio shifts are performed by an electronically controlled system managing the timing of the shift, the operation of the clutch between engine and gearbox and the speed and torque of the engine. The system selects and engages the most suitable forward gear automatically, but can be overridden by the driver using a manual mode; ---|--- (20) | ‘Dual Clutch Transmission (DCT)’ means an automatically shifting transmission with two friction clutches and several selectable speed ratios that are obtained by the use of tooth clutches. The ratio shifts are performed by an electronically controlled system managing the timing of the shift, the operation of the clutches and the speed and torque of the engine. The system selects the most suitable gear automatically, but can be overridden by the driver using a manual mode; ---|--- (21) | ‘Retarder’ means an auxiliary braking device in a vehicle powertrain; aimed for permanent braking; ---|--- (22) | ‘Case S’ means the serial arrangement of a torque converter and the connected mechanical parts of the transmission; ---|--- (23) | ‘Case P’ means the parallel arrangement of a torque converter and the connected mechanical parts of the transmission (e.g. in power split installations); ---|--- (24) | ‘Automatic Powershifting Transmission (APT)’ means an automatically shifting transmission with more than two friction clutches and several selectable speed ratios that are obtained mainly by the use of those friction clutches. The ratio shifts are performed by an electronically controlled system managing the timing of the shift, the operation of the clutches and the speed and torque of the engine. The system selects the most suitable gear automatically, but can be overridden by the driver using a manual mode.

Complement of input files for the simulation tool For each gear a torque loss map covering the defined input speed and input torque steps shall be determined with one of the specified testing options or standard torque loss values. For the input file for the simulation tool, this basic torque loss map shall be complemented as described in the following: 3.4.1. In the cases the highest tested input speed was the last speed step below the defined maximum permissible transmission speed, an extrapolation of the torque loss shall be applied up to the maximum speed with linear regression based on the two last measured speed steps. 3.4.2. In the cases the highest tested input torque was the last torque step below the defined maximum permissible transmission torque, an extrapolation of the torque loss shall be applied up to the maximum torque with linear regression based on the two last measured torque steps for the corresponding speed step. In order to handle engine torque tolerances, etc., the simulation tool will, if required, perform an extrapolation of the torque loss for input torques up to 10 % above said defined maximum permissible transmission torque. 3.4.3. In the case of extrapolation of the torque loss values for maximum input speed and maximum input torque at the same time, the torque loss for the combined point of highest speed and highest torque shall be calculated with two-dimensional linear extrapolation. 3.4.4. If the maximum output torque exceeds 10 kNm (for a theoretical loss free transmission), and/or for all speed and torque points with input power higher than the specified maximum input power, the manufacturer may choose to take the torque loss values for all torques higher than 10 kNm, and/or for all speed and torque points with input power higher than the specified maximum input power, respectively, from one of: (1) | Calculated fallback values (Appendix 8) ---|--- (2) | Option 1 ---|--- (3) | Option 2 or 3 in combination with a torque sensor for higher output torques (if required) ---|--- For cases (i) and (ii) in Option 2, the torque losses at load shall be measured at the input torque that corresponds to output torque 10 kNm and/or the specified maximum input power. 3.4.5. For speeds below the defined minimum speed and the additional input speed step of 0 rpm, the reported torque losses determined for the minimum speed step shall be copied. 3.4.6. To cover the range of negative input torques during vehicle coasting conditions, the torque loss values for positive input torques shall be copied for the related negative input torques. 3.4.7. Upon agreement of an approval authority, the torque losses for the input speeds below 1 000 rpm may be replaced by the torque losses at 1 000 rpm when the measurement is technically not possible. 3.4.8. If the measurement of speed points is technically not possible (e.g. due to natural frequency), the manufacturer may, in agreement with the approval authority, calculate the torque losses by interpolation or extrapolation (limited to max. 1 speed step per gear). 3.4.9. The torque loss map data shall be formatted and saved as specified in Appendix 12 to this Annex. 4\. Torque converter (TC) The torque converter characteristics to be determined for the simulation tool input consist of Tpum 1000 (the reference torque at 1 000 rpm input speed) and μ (the torque ratio of the torque converter). Both are depending on the speed ratio v (= output (turbine) speed / input (pump) speed for the torque converter) of the torque converter. For determination of the characteristics of the TC, the applicant for a certificate shall apply the following method, irrespective of the chosen option for the assessment of the transmission torque losses. To take the two possible arrangements of the TC and the mechanical transmission parts into account, the following differentiation between case S and P shall apply: Case S | : | TC and mechanical transmission parts in serial arrangement ---|---|--- Case P | : | TC and mechanical transmission parts in parallel arrangement (power split installation) For case S arrangements the TC characteristics may be evaluated either separate from the mechanical transmission or in combination with the mechanical transmission. For case P arrangements the evaluation of TC characteristic is only possible in combination with the mechanical transmission. However, in this case and for the hydromechanical gears subject to measurement the whole arrangement, torque converter and mechanical transmission, is considered as a TC with similar characteristic curves as a sole torque converter. For the determination of the torque converter characteristics two measurement options may be applied: (i) | Option A: measurement at constant input speed ---|--- (ii) | Option B: measurement at constant input torque according to SAE J643 ---|--- The manufacturer may choose option A or B for case S and case P arrangements. For the input to the simulation tool, the torque ratio μ and reference torque Tpum of the torque converter shall be measured for a range of v ≤ 0,95 (= vehicle propulsion mode). The range of v ≥ 1,00 (= vehicle coasting mode) may either be measured or covered by using the standard values of Table 1. In case of measurements together with a mechanical transmission the overrun point may be different from v = 1,00 and therefor the range of measured speed ratios shall be adjusted accordingly. In case of use of standard values the data on torque converter characteristics provided to the simulation tool shall only cover the range of v ≤ 0,95 (or the adjusted speed ratio). The simulation tool automatically adds the standard values for overrun conditions.

Other torque transferring components (OTTC) The scope of this section includes engine retarders, transmission retarders, driveline retarders, and components that are treated in the simulation tool as a retarder. These components include vehicle starting devices like a single wet transmission input clutch or hydro-dynamic clutch. 5.1. Methods for establishing retarder drag losses The retarder drag torque loss is a function of the retarder rotor speed. Since the retarder can be integrated in different parts of the vehicle driveline, the retarder rotor speed depends on the drive part (= speed reference) and step-up ratio between drive part and retarder rotor as shown in Table 2. Table 2 Retarder rotor speeds Configuration | Speed reference | Retarder rotor speed calculation ---|---|--- | A. | Engine Retarder ---|--- Engine Speed | nretarder = nengine * istep-up | B. | Transmission Input Retarder ---|--- Transmission Input Shaft Speed | nretarder = ntransm.input * istep-up = ntransm.output * itransm * istep-up | C. | Transmission Output Retarder or Propshaft Retarder ---|--- Transmission Output Shaft Speed | nretarder = ntransm.output * istep-up where: istep-up | = | step-up ratio = retarder rotor speed/drive part speed ---|---|--- itransm | = | transmission ratio = transmission input speed/transmission output speed Retarder configurations that are integrated in the engine and cannot be separated from the engine shall be tested in combination with the engine. This section does not cover these non-separable engine integrated retarders. Retarders that can be disconnected from the driveline or the engine by any kind of clutch are considered to have zero rotor speed in disconnected condition and therefore have no power losses. The retarder drag losses shall be measured with one of the following two methods: (1) | Measurement on the retarder as a stand-alone unit ---|--- (2) | Measurement in combination with the transmission ---|--- 5.1.1. General requirements In case the losses are measured on the retarder as stand-alone unit, the results are affected by the torque losses in the bearings of the test setup. It is permitted to measure these bearing losses and subtract them from the retarder drag loss measurements. The manufacturer shall guarantee that the retarder used for the measurements is in accordance with the drawing specifications for series production retarders. Modifications to the retarder to meet the testing requirements of this Annex, e.g. for the inclusion of measurement sensors or the adaption of an external oil conditioning systems are permitted. Based on the family described in Appendix 6 to this Annex, measured drag losses for transmissions with retarder can be used for the same (equivalent) transmission without retarder. The use of the same transmission unit for measuring the torque losses of variants with and without retarder is permitted. Upon request of the approval authority the applicant for a certificate shall specify and prove the conformity with the requirements defined in this Annex. 5.1.2. Run-in On request of the applicant a run-in procedure may be applied to the retarder. The following provisions shall apply for a run-in procedure. 5.1.2.1 If the manufacturer applies a run-in procedure to the retarder, the run-in time for the retarder shall not exceed 100 hours at zero retarder apply torque. Optionally a share of a maximum of 6 hours with retarder apply torque may be included. 5.1.3. Test conditions 5.1.3.1. Ambient temperature The ambient temperature during the test shall be in a range of 25 °C ± 10 K. The ambient temperature shall be measured 1 m laterally from the retarder. 5.1.3.2. Ambient pressure For magnetic retarders the minimum ambient pressure shall be 899 hPa according to International Standard Atmosphere (ISA) ISO 2533. 5.1.3.3. Oil or water temperature For hydrodynamic retarders: Except for the fluid, no external heating is allowed. In case of testing as stand-alone unit, the retarder fluid temperature (oil or water) shall not exceed 87 °C. In case of testing in combination with transmission, the oil temperature limits for transmission testing shall apply. 5.1.3.4. Oil or water quality New, recommended first fill oil for the European market shall be used in the test. For water retarders the water quality shall meet the specifications set out by the manufacturer for the retarder. The water pressure shall be set to a fixed value close to vehicle condition (1 ± 0,2 bar relative pressure at retarder input hose). 5.1.3.5. Oil viscosity If several oils are recommended for first fill, they are considered to be equal if the oils have a kinematic viscosity within 50 % of each other at the same temperature (within the specified tolerance band for KV100). 5.1.3.6. Oil or water level The oil/water level shall meet the nominal specifications for the retarder. 5.1.4. Installation The electric machine, the torque sensor, and speed sensor shall be mounted at the input side of the retarder or transmission. The installation of the retarder (and transmission) shall be done with an inclination angle as for installation in the vehicle according to the homologation drawing ± 1° or at 0° ± 1°. 5.1.5. Measurement equipment As specified for transmission testing in 3.1.4. 5.1.6. Test procedure 5.1.6.1. Zero torque signal compensation: As specified for transmission testing in 3.1.6.1. 5.1.6.2. Measurement sequence The torque loss measurement sequence for the retarder testing shall follow the provisions for the transmission testing defined in 3.1.6.3.2. to 3.1.6.3.5. 5.1.6.2.1. Measurement on the retarder as stand-alone unit When the retarder is tested as stand-alone unit, torque loss measurements shall be conducted using the following speed points: 200, 400, 600, 900, 1 200, 1 600, 2 000, 2 500, 3 000, 3 500, 4 000, 4 500, 5 000, continued up to the maximum retarder rotor speed. 5.1.6.2.2. Measurement in combination with the transmission 5.1.6.2.2.1. In case the retarder is tested in combination with a transmission, the selected transmission gear shall allow the retarder to operate at its maximum rotor speed. 5.1.6.2.2. The torque loss shall be measured at the operating speeds as indicated for the related transmission testing. 5.1.6.2.2.3. Measurement points may be added for transmission input speeds below 600 rpm if requested by the manufacturer. 5.1.6.2.2.4. The manufacturer may separate the retarder losses from the total transmission losses by testing in the order as described below: (1) | The load-independent torque loss for the complete transmission including retarder shall be measured as defined in point 3.1.2. for transmission testing in one of the higher transmission gears = Tl,in,withret ---|--- (2) | The retarder and related parts shall be replaced with parts required for the equivalent transmission variant without retarder. The measurement of point (1) shall be repeated. = Tl,in,withoutret ---|--- (3) | The load-independent torque loss for the retarder system shall be determined by calculating the differences between the two test data sets = Tl,in,retsys = Tl,in,withret – Tl,in,withoutret ---|--- 5.1.7. Measurement signals and data recording As specified for transmission testing in 3.1.5. 5.1.8. Measurement validation All recorded data shall be checked and processed as defined for transmission testing in 3.1.7. 5.2. Complement of input files for the simulation tool 5.2.1 Retarder torque losses for speeds below the lowest measurement speed shall be set equal to the measured torque loss at this lowest measurement speed. 5.2.2 In case the retarder losses were separated out from the total losses by calculating the difference in data sets of testing with and without a retarder (see 5.1.6.2.2.4.), the actual retarder rotor speeds depend on the retarder location, and/or selected gear ratio and retarder step-up ratio and thereby may differ from the measured transmission input shaft speeds. The actual retarder rotor speeds relative to the measured drag loss data shall be calculated as described in 5.1. Table 2. 5.2.3 The torque loss map data shall be formatted and saved as specified in Appendix 12 to this Annex. 6\. Additional driveline components (ADC) / angle drive 6.1. Methods for establishing angle drive losses The angle drive losses shall be determined using one of the following cases: 6.1.1. Case A: Measurement on a separate angle drive For the torque loss measurement of a separate angle drive, the three options as defined for the determination of the transmission losses shall apply: Option 1 | : | Measured torque independent losses and calculated torque dependent losses (Transmission test option 1) ---|---|--- Option 2 | : | Measured torque independent losses and measured torque dependent losses at full load (Transmission test option 2) Option 3 | : | Measurement under full load points (Transmission test option 3) The measurement of the angle drive losses shall follow the procedure described for the related transmission test option in paragraph 3 diverging in the following requirements: 6.1.1.1 Applicable speed range: From 200 rpm (at the shaft to which the angle drive is connected) up to the maximum speed according to specifications of the angle drive or the last speed step before the defined maximum speed. 6.1.1.2 Speed step size: 200 rpm 6.1.2. Case B: Individual measurement of an angle drive connected to a transmission In case the angle drive is tested in combination with a transmission, the testing shall follow one of the defined options for transmission testing: Option 1 | : | Measured torque independent losses and calculated torque dependent losses (Transmission test option 1) ---|---|--- Option 2 | : | Measured torque independent losses and measured torque dependent losses at full load (Transmission test option 2) Option 3 | : | Measurement under full load points (Transmission test option 3) 6.1.2.1 The manufacturer may separate the angle drive losses from the total transmission losses by testing in the order as described below: (1) | The torque loss for the complete transmission including angle drive shall be measured as defined for the applicable transmission testing option = Tl,in,withad ---|--- (2) | The angle drive and related parts shall be replaced with parts required for the equivalent transmission variant without angle drive. The measurement of point (1) shall be repeated. = Tl,in,withoutad ---|--- (3) | The torque loss for the angle drive system shall be determined by calculating the differences between the two test data sets = Tl,in,adsys = Tl,in,withad – Tl,in,withoutad ---|--- 6.2. Complement of input files for the simulation tool 6.2.1. Torque losses for speeds below the above defined minimum speed shall be set equal to the torque loss at the minimum speed. 6.2.2. In the cases the highest tested angle drive input speed was the last speed step below the defined maximum permissible angle drive speed, an extrapolation of the torque loss shall be applied up to the maximum speed with linear regression based on the two last measured speed steps. 6.2.3. To calculate the torque loss data for the input shaft of the transmission the angle drive is to be combined with, linear interpolation and extrapolation shall be used. 7\. Conformity of the certified CO2 emissions and fuel consumption related properties 7.1. Every transmission, torque converter (TC), other torque transferring components (OTTC) and additional driveline components (ADC) shall be so manufactured as to conform to the approved type with regard to the description as given in the certificate and its annexes. The conformity of the certified CO2 emissions and fuel consumption related properties procedures shall comply with those set out in Article 12 of Directive 2007/46/EC. 7.2 Torque converter (TC), other torque transferring components (OTTC) and additional driveline components (ADC) shall be excluded from the production conformity testing provisions of section 8 to this annex. 7.3 Conformity of the certified CO2 emissions and fuel consumption related properties shall be checked on the basis of the description in the certificates set out in Appendix 1 to this Annex. 7.4 Conformity of the certified CO2 emissions and fuel consumption related properties shall be assessed in accordance with the specific conditions laid down in this paragraph. 7.5 The manufacturer shall test annually at least the number of transmissions indicated in Table 3 based on the total annual production number of the transmissions produced by the manufacturer. For the purpose of establishing the production numbers, only transmissions which fall under the requirements of this Regulation shall be considered. 7.6 Each transmission which is tested by the manufacturer shall be representative for a specific family. Notwithstanding provisions of the point 7.10., only one transmission per family shall be tested. 7.7 For the total annual production volumes between 1 001 and 10 000 transmissions, the choice of the family for which the tests shall be performed shall be agreed between the manufacturer and the approval authority. 7.8 For the total annual production volumes above 10 000 transmissions, the transmission family with the highest production volume shall always be tested. The manufacturer shall justify (ex. by showing sales numbers) to the approval authority the number of tests which has been performed and the choice of the families. The remaining families for which the tests are to be performed shall be agreed between the manufacturer and the approval authority.

For the purpose of the conformity of the certified CO2 emissions and fuel consumption related properties testing the approval authority shall identify together with the manufacturer the transmission type(s) to be tested. The approval authority shall ensure that the selected transmission type(s) is manufactured to the same standards as for serial production.. 7.10 If the result of a test performed in accordance with point 8 is higher than the one specified in point 8.1.3., 3 additional transmissions from the same family shall be tested. If at least one of them fails, provisions of Article 23 shall apply. 8\.

General A transmission, torque converter, other torque transferring components or additional driveline components family is characterized by design and performance parameters. These shall be common to all members within the family. The manufacturer may decide which transmission, torque converter, other torque transferring components or additional driveline components belong to a family, as long as the membership criteria listed in this Appendix are respected. The related family shall be approved by the Approval Authority. The manufacturer shall provide to the Approval Authority the appropriate information relating to the members of the family. 1.1 Special cases In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that only transmissions, torque converter, other torque transferring components or additional driveline components with similar characteristics are included within the same family. These cases shall be identified by the manufacturer and notified to the Approval Authority. It shall then be taken into account as a criterion for creating a new transmission, torque converter, other torque transferring components or additional driveline components family. In case of devices or features, which are not listed in paragraph 9. and which have a strong influence on the level of performance, this equipment shall be identified by the manufacturer on the basis of good engineering practice, and shall be notified to the Approval Authority.

Introduction This Annex describes the certification provisions regarding the torque losses of propulsion axles for heavy duty vehicles. Alternatively to the certification of axles the calculation procedure for the standard torque loss as defined in Appendix 3 to this Annex can be applied for the purpose of the determination of vehicle specific CO2 emissions. 2\. Definitions For the purposes of this Annex the following definitions shall apply: (1) | ‘Single reduction axle (SR)’ means a driven axle with only one gear reduction, typically a bevel gear set with or without hypoid offset. ---|--- (2) | ‘Single portal axle (SP)’ means an axle, that has typically a vertical offset between the rotating axis of the crown gear and the rotating axis of the wheel due to the demand of a higher ground clearance or a lowered floor to allow a low floor concept for inner city buses. Typically, the first reduction is a bevel gear set, the second one a spur gear set with vertical offset close to the wheels. ---|--- (3) | ‘Hub reduction axle (HR)’ means a driven axle with two gear reductions. The first is typically a bevel gear set with or without hypoid offset. The other is a planetary gear set, what is typically placed in the area of the wheel hubs. ---|--- (4) | ‘Single reduction tandem axle (SRT)’ means a driven axle that is basically similar to a single driven axle, but has also the purpose to transfer torque from the input flange over an output flange to a further axle. The torque can be transferred with a spur gear set close at the input flange to generate a vertical offset for the output flange. Another possibility is to use a second pinion at the bevel gear set, what takes off torque at the crown wheel. ---|--- (5) | ‘Hub reduction tandem axle (HRT)’ means a hub reduction axle, what has the possibility to transfer torque to the rear as described under single reduction tandem axle (SRT). ---|--- (6) | ‘Axle housing’ means the housing parts that are needed for structural capability as well as for carrying the driveline parts, bearings and sealings of the axle.

---|--- (7) | ‘Pinion’ means a part of a bevel gear set which usually consists of two gears. The pinion is the driving gear which is connected with the input flange. In case of a SRT / HRT, a second pinion can be installed to take off torque from the crown wheel. ---|--- (8) | ‘Crown wheel’ means a part of a bevel gear set which usually consists of two gears. The crown wheel is the driven gear and is connected with the differential cage. ---|--- (9) | ‘Hub reduction’ means the planetary gear set that is installed commonly outside the planetary bearing at hub reduction axles. The gear set consists of three different gears. The sun, the planetary gears and the ring gear. The sun is in the centre, the planetary gears are rotating around the sun and are mounted to the planetary carrier that is fixed to the hub. Typically, the number of planetary gears is between three and five. The ring gear is not rotating and fixed to the axle beam. ---|--- (10) | ‘Planetary gear wheels’ means the gears that rotate around the sun within the ring gear of a planetary gear set. They are assembled with bearings on a planetary carrier, what is joined to a hub. ---|--- (11) | ‘Oil type viscosity grade’ means a viscosity grade as defined by SAE J306. ---|--- (12) | ‘Factory fill oil’ means the oil type viscosity grade that is used for the oil fill in the factory and which is intended to stay in the axle for the first service interval. ---|--- (13) | ‘Axle line’ means a group of axles that share the same basic axle-function as defined in the family concept. ---|--- (14) | ‘Axle family’ means a manufacturer's grouping of axles which through their design, as defined in Appendix 4 of this Annex, have similar design characteristics and CO2 and fuel consumption properties. ---|--- (15) | ‘Drag torque’ means the required torque to overcome the inner friction of an axle when the wheel ends are rotating freely with 0 Nm output torque. ---|--- (16) | ‘Mirror inverted axle casing’ means the axle casing is mirrored regarding to the vertical plane. ---|--- (17) | ‘Axle input’ means the side of the axle on which the torque is delivered to the axle. ---|--- (18) | ‘Axle output’ means the side(s) of the axle where the torque is delivered to the wheels. ---|--- 3\. General requirements The axle gears and all bearings, except wheel end bearings used for the measurements, shall not be used. On request of the applicant different gear ratios can be tested in one axle housing using the same wheel ends. Different axle ratios of hub reduction axles and single portal axles (HR, HRT, SP) may be measured by exchanging the hub reduction only. The provisions as specified in Appendix 4 to this Annex shall apply. The total run-time for the optional run-in and the measurement of an individual axle (except for the axle housing and wheel-ends) shall not exceed 120 hours. For testing the losses of an axle the torque loss map for each ratio of an individual axle shall be measured, however axles can be grouped in axle families following the provisions of Appendix 4 to this Annex. 3.1 Run-in On request of the applicant a run-in procedure may be applied to the axle. The following provisions shall apply for a run-in procedure. 3.1.1 Only factory fill oil shall be used for the run-in procedure. The oil used for the run-in shall not be used for the testing described in paragraph 4. 3.1.2 The speed and torque profile for the run-in procedure shall be specified by the manufacturer. 3.1.3 The run-in procedure shall be documented by the manufacturer with regard to run-time, speed, torque and oil temperature and reported to the approval authority. 3.1.4 The requirements for the oil temperature (4.3.1), measurement accuracy (4.4.7) and test set-up (4.2) do not apply for the run-in procedure. 4\. Testing procedure for axles 4.1 Test conditions 4.1.1 Ambient temperature The temperature in the test cell shall be maintained to 25 °C ± 10 °C. The ambient temperature shall be measured within a distance of 1 m to the axle housing. Forced heating of the axle may only be applied by an external oil conditioning system as described in 4.1.5. 4.1.2 Oil temperature The oil temperature shall be measured at the centre of the oil sump or at any other suitable point in accordance with good engineering practice. In case of external oil conditioning, alternatively the oil temperature can be measured in the outlet line from the axle housing to the conditioning system within 5 cm downstream the outlet. In both cases the oil temperature shall not exceed 70 °C. 4.1.3 Oil quality Only recommended factory fill oils as specified by the axle manufacturer shall be used for the measurement. In the case of testing different gear ratio variants with one axle housing, new oil shall be filled in for each single measurement. 4.1.4 Oil viscosity If different oils with multiple viscosity grades are specified for the factory fill, the manufacturer shall choose the oil with the highest viscosity grade for performing the measurements on the parent axle. If more than one oil within the same viscosity grade is specified within one axle family as factory fill oil, the applicant may choose one oil of these for the measurement related to certification. 4.1.5 Oil level and conditioning The oil level or filling volume shall be set to the maximum level as defined in the manufacturer's maintenance specifications. An external oil conditioning and filtering system is permitted. The axle housing may be modified for the inclusion of the oil conditioning system. The oil conditioning system shall not be installed in a way which would enable changing oil levels of the axle in order to raise efficiency or to generate propulsion torques in accordance with good engineering practice. 4.2 Test set-up For the purpose of the torque loss measurement different test set-ups are permitted as described in paragraph 4.2.3 and 4.2.4. 4.2.1 Axle installation In case of a tandem axle, each axle shall be measured separately. The first axle with longitudinal differential shall be locked. The output shaft of drive-through axles shall be installed freely rotatable. 4.2.2 Installation of torque meters 4.2.2.1 For a test setup with two electric machines, the torque meters shall be installed on the input flange and on one wheel end while the other one is locked. 4.2.2.2 For a test setup with three electric machines, the torque meters shall be installed on the input flange and on each wheel end. 4.2.2.3 Half shafts of different lengths are permitted in a two machine set-up in order to lock the differential and to ensure that both wheel ends are turning. 4.2.3 Test set-up ‘Type A’ A test set-up considered ‘Type A’ consists of a dynamometer on the axle input side and at least one dynamometer on the axle output side(s). Torque measuring devices shall be installed on the axle input- and output- side(s). For type A set-ups with only one dynamometer on the output side, the free rotating end of the axle shall be locked. To avoid parasitic losses, the torque measuring devices shall be positioned as close as possible to the axle input- and output- side(s) being supported by appropriate bearings. Additionally mechanical isolation of the torque sensors from parasitic loads of the shafts, for example by installation of additional bearings and a flexible coupling or lightweight cardan shaft between the sensors and one of these bearings can be applied. Figure 1 shows an example for a test test-up of Type A in a two dynamometer lay-out. For Type A test set-up configurations the manufacturer shall provide an analysis of the parasitic loads. Based on this analysis the approval authority shall decide about the maximum influence of parasitic loads. However the value ipara cannot be lower than 10 %.

The maximum influence of parasitic loads ipara for those configurations shall be set to 100 %. Lower values for ipara may be used in agreement with the approval authority. 4.3 Test procedure To determine the torque loss map for an axle, the basic torque loss map data shall be measured and calculated as specified in paragraph 4.4. The torque loss results shall be complemented in accordance with 4.4.8 and formatted in accordance with Appendix 6 for the further processing by Vehicle Energy Consumption calculation Tool. 4.3.1 Measurement equipment The calibration laboratory facilities shall comply with the requirements of either ISO/TS 16949, ISO 9000 series or ISO/IEC 17025. All laboratory reference measurement equipment, used for calibration and/or verification, shall be traceable to national (international) standards. 4.3.1.1 Torque measurement The torque measurement uncertainty shall be calculated and included as described in paragraph 4.4.7.

The raw data do not need to be reported. Signal filtering may be applied in agreement with the approval authority. Any aliasing effect shall be avoided. 4.3.3 Torque range: The extent of the torque loss map to be measured is limited to: — | either an output torque of 10 kNm ---|--- — | or an input torque of 5 kNm ---|--- — | or the maximum engine power tolerated by the manufacturer for a specific axle or in case of multiple driven axles according to the nominal power distribution. ---|--- 4.3.3.1 The manufacturer may extend the measurement up to 20 kNm output torque by means of linear extrapolation of torque losses or by performing measurements up to 20 kNm output torque with steps of 2 000 Nm. For this additional torque range another torque sensor at the output side with a maximum torque of 20 kNm (2-machine layout) or two 10 kNm sensors (3-machine layout) shall be used. If the radius of the smallest tire is reduced (e.g. product development) after completing the measurement of an axle or when the physic boundaries of the test stand are reached (e.g. by product development changes), the missing points may be extrapolated by the manufacturer out of the existing map. The extrapolated points shall not exceed more than 10 % of all points in the map and the penalty for these points is 5 % torque loss to be added on the extrapolated points. 4.3.3.2 Output torque steps to be measured: 250 Nm < Tout < 1 000 Nm | : | 250 Nm steps ---|---|--- 1 000 Nm ≤ Tout ≤ 2 000 Nm | : | 500 Nm steps 2 000 Nm ≤ Tout ≤ 10 000 Nm | : | 1 000 Nm steps Tout > 10 000 Nm | : | 2 000 Nm steps If the maximum input torque is limited by the manufacturer, the last torque step to be measured is the one below this maximum without consideration of any losses. In that case an extrapolation of the torque loss shall be applied up to the torque corresponding to the manufacturer's limitation with the linear regression based on the torque steps of the corresponding speed step. 4.3.4 Speed range The range of test speeds shall comprise from 50 rpm wheel speed to the maximum speed. The maximum test speed to be measured is defined by either the maximum axle input speed or the maximum wheel speed, whichever of the following conditions is reached first: 4.3.4.1 | The maximum applicable axle input speed may be limited to design specification of the axle. ---|--- 4.3.4.2 | The maximum wheel speed is measured under consideration of the smallest applicable tire diameter at a vehicle speed of 90 km/h for trucks and 110 km/h for coaches. If the smallest applicable tire diameter is not defined, paragraph 4.3.4.1 shall apply. ---|--- 4.3.5 Wheel speed steps to be measured The wheel speed step width for testing shall be 50 rpm. 4.4 Measurement of torque loss maps for axles 4.4.1 Testing sequence of the torque loss map For each speed step the torque loss shall be measured for each output torque step starting from 250 Nm upward to the maximum and downward to the minimum. The speed steps can be run in any order. Interruptions of the sequence for cooling or heating purposes are permitted. 4.4.2 Measurement duration The measurement duration for each single grid point shall be 5-15 seconds. 4.4.3 Averaging of grid points The recorded values for each grid point within the 5-15 seconds interval according to point 4.4.2. shall be averaged to an arithmetic mean. All four averaged intervals of corresponding speed and torque grid points from both sequences measured each upward and downward shall be averaged to an arithmetic mean and result into one torque loss value. 4.4.4 The torque loss (at input side) of the axle shall be calculated by where: Tloss | = | Torque loss of the axle at the input side [Nm] ---|---|--- Tin | = | Input torque [Nm] igear | = | Axle gear ratio [-] Tout | = | Output torque [Nm] 4.4.5 Measurement validation 4.4.5.1 The averaged speed values per grid point (20 s interval) shall not deviate from the setting values by more than ± 5 rpm for the output speed. 4.4.5.2 The averaged output torque values as described under 4.4.3 for each grid point shall not deviate more than ± 20 Nm or ± 1 % from the torque set point for the according grid point, whichever is the higher value. 4.4.5.3 If the above specified criteria are not met the measurement is void. In this case, the measurement for the entire affected speed step shall be repeated. After passing the repeated measurement, the data shall be consolidated. 4.4.6 Uncertainty calculation The total uncertainty UT,loss of the torque loss shall be calculated based on the following parameters: i. | Temperature effect ---|--- ii. | Parasitic loads ---|--- iii. | Uncertainty (incl. sensitivity tolerance, linearity, hysteresis and repeatability) ---|--- The total uncertainty of the torque loss (UT,loss) is based on the uncertainties of the sensors at 95 % confidence level. The calculation shall be done for each applied sensor (e.g. three machine lay out: UT,in, UT,out,1, UTout,2) as the square root of the sum of squares (‘Gaussian law of error propagation’). wpara = senspara * ipara where: UT,in/out | = | Uncertainty of input/output torque loss measurement separately for input and output torque; [Nm] ---|---|--- igear | = | Axle gear ratio [-] UTKC | = | Uncertainty by temperature influence on current torque signal; [Nm] wtkc | = | Temperature influence on current torque signal per Kref, declared by sensor manufacturer; [%] UTK0 | = | Uncertainty by temperature influence on zero torque signal (related to nominal torque) [Nm] wtk0 | = | Temperature influence on zero torque signal per Kref (related to nominal torque), declared by sensor manufacturer; [%] Kref | = | Reference temperature span for tkc and tk0, declared by sensor manufacturer; [°C] ΔK | = | Absolute difference in sensor temperature measured at torque sensor between calibration and measurement; If the sensor temperature cannot be measured, a default value of ΔK = 15 K shall be used [°C] Tc | = | Current/measured torque value at torque sensor; [Nm] Tn | = | Nominal torque value of torque sensor; [Nm] Ucal | = | Uncertainty by torque sensor calibration; [Nm] wcal | = | Relative calibration uncertainty (related to nominal torque); [%] kcal | = | calibration advancement factor (if declared by sensor manufacturer, otherwise = 1) Upara | = | Uncertainty by parasitic loads; [Nm] wpara | = | senspara * ipara Relative influence of forces and bending torques caused by misalignment senspara | = | Maximum influence of parasitic loads for specific torque sensor declared by sensor manufacturer [%]; if no specific value for parasitic loads is declared by the sensor manufacturer, the value shall be set to 1,0 % ipara | = | Maximum influence of parasitic loads for specific torque sensor depending on test set-up as indicated in section 4.2.3 and 4.2.4 of this annex. 4.4.7 Assessment of total uncertainty of the torque loss In the case the calculated uncertainties UT,in/out are below the following limits, the reported torque loss Tloss,rep shall be regarded as equal to the measured torque loss Tloss . UT,in : 7,5 Nm or 0,25 % of the measured torque, whichever allowed uncertainty value is higher UT,out : 15 Nm or 0,25 % of the measured torque, whichever allowed uncertainty value is higher In the case of higher calculated uncertainties, the part of the calculated uncertainty exceeding the above specified limits shall be added to Tloss for the reported torque loss Tloss,rep as follows: If the limits of UT,in are exceeded: | Tloss,rep = Tloss \+ ΔUTin ---|--- | ΔUT,in = MIN((UT,in – 0,25 % * Tc) or (UT,in – 7,5 Nm)) ---|--- If limits of UT,out out are exceeded: | Tloss,rep = Tloss \+ ΔUT,out/igear ---|--- | ΔUT,out = MIN((UT,out – 0,25 % * Tc) or (UT,out – 15Nm)) ---|--- where: UT,in/out | = | Uncertainty of input/output torque loss measurement separately for input and output torque; [Nm] ---|---|--- igear | = | Axle gear ratio [-] ΔUT | = | The part of the calculated uncertainty exceeding the specified limits 4.4.8 Complement of torque loss map data 4.4.8.1 If the torque values exceed the upper range limit linear extrapolation shall be applied. For the extrapolation the slope of linear regression based on all measured torque points for the corresponding speed step shall be applied. 4.4.8.2 For the output torque range values below 250 Nm the torque loss values of the 250 Nm point shall be applied. 4.4.8.3 For 0 rpm wheel speed rpm the torque loss values of the 50 rpm speed step shall be applied. 4.4.8.4 For negative input torques (e.g. overrun, free rolling), the torque loss value measured for the related positive input torque shall be applied. 4.4.8.5 In case of a tandem axle, the combined torque loss map for both axles shall be calculated out of the test results for the single axles.

The applicant for a certificate shall submit to the approval authority an application for a certificate for an axle family based on the family criteria as indicated in paragraph 3. An axle family is characterized by design and performance parameters. These shall be common to all axles within the family. The axle manufacturer may decide which axle belongs to an axle family, as long as the family criteria of paragraph 4 are respected. In addition to the parameters listed in paragraph 4, the axle manufacturer may introduce additional criteria allowing the definition of families of more restricted size. These parameters are not necessarily parameters that have an influence on the level of performance. The axle family shall be approved by the approval authority. The manufacturer shall provide to the approval authority the appropriate information relating to the performance of the members of the axle family. 2\. Special cases In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that only axles with similar characteristics are included within the same axle family. These cases shall be identified by the manufacturer and notified to the approval authority. It shall then be taken into account as a criterion for creating a new axle family. In case of parameters, which are not listed in paragraph 3 and which have a strong influence on the level of performance, this parameters shall be identified by the manufacturer on the basis of good engineering practice, and shall be notified to the approval authority. 3\.

Geometry changes due to an optional integration of a differential lock are permitted within the same axle family. In case of mirror inverted axle casings of axles, the mirror inverted axles can be combined in the same axle family as the origin axles, under the premise, that the bevel gear sets are adapted to the other running direction (change of spiral direction). ---|--- (g) | Crown wheel diameter (+ 1,5/– 8 % ref. to the largest drawing diameter) ---|--- (h) | Vertical hypoid offset pinion/crown wheel within ± 2 mm ---|--- (i) | In case of single portal axles (SP): Pinion angle with respect to horizontal plane within ± 5° ---|--- (j) | In case of single portal axles (SP): Angle between pinion axle and crown wheel axle within ± 3,5° ---|--- (k) | In case of hub reduction and single portal axles (HR, HRT, FHR, SP): Same number of planetary gear and spur wheels ---|--- (l) | Gear ratio of every gear step within an axle in a range of 1, as long as only one gear set is changed ---|--- (m) | Oil level within ± 10 mm or oil volume ± 0,5 litre referring to drawing specification and the installation position in the vehicle ---|--- (n) | Same oil type viscosity grade (recommended factory fill) ---|--- (o) | For all bearings: same bearing rolling/sliding circle diameter (inner/outer) and width within ± 2 mm ref. to drawing ---|--- (p) | Same seal type (main diameters, oil lip number) within ± 0,5 mm ref. to drawing ---|--- 4\.

General An air drag family is characterized by design and performance parameters. These shall be common to all vehicles within the family. The manufacturer may decide which vehicles belong to an air drag family as long as the membership criteria listed in paragraph 4 are respected. The air drag family shall be approved by the approval authority. The manufacturer shall provide to the approval authority the appropriate information relating to the air drag of the members of the air drag family. 2\. Special cases In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that only vehicles with similar characteristics are included within the same air drag family. These cases shall be identified by the manufacturer and notified to the approval authority. It shall then be taken into account as a criterion for creating a new air drag family. In addition to the parameters listed in paragraph 4, the manufacturer may introduce additional criteria allowing the definition of families of more restricted size. 3\. All vehicles within a family get the same air drag value than the corresponding ‘parent vehicle’ of the family. This air drag value has to be measured on the parent vehicle according to the constant speed test procedure as described in section 3 of the main part of this Annex. 4\. Parameter defining the air drag family: 4.1. Vehicles are allowed to be grouped within a family if the following criteria are fulfilled: (a) | Same cabin width and body in white geometry up to B-pillar and above the heel point excluding the cab bottom (e.g. engine tunnel). All members of the family stay within a range of ± 10 mm to the parent vehicle. ---|--- (b) | Same roof height in vertical Z.
