7.7.2017 | EN | Official Journal of the European Union | L 175/708 ---|---|---|--- * * * COMMISSION REGULATION (EU) 2017/1154 of 7 June 2017 amending Regulation (EU) 2017/1151 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Regulation (EC) No 692/2008 and Directive 2007/46/EC of the European Parliament and of the Council as regards real- driving emissions from light passenger and commercial vehicles (Euro 6) (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 715/2007 of the European Parliament and of the Council of 20 June 2007 on type approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information (1), and in particular Article 14(3) 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(2) thereof, Whereas: (1) | Regulation (EC) No 715/2007 is a separate regulatory act under the type-approval procedure laid down by Directive 2007/46/EC. ---|--- (2) | Regulation (EC) No 715/2007 requires new light passenger and commercial vehicles to comply with certain emission limits and lays down additional requirements on access to information. The specific technical provisions necessary to implement that Regulation are contained in Commission Regulation (EU) 2017/1151 (3). ---|--- (3) | The Commission has performed a detailed analysis of the procedures, tests and requirements for type approval that are set out in Regulation (EC) No 692/2008 on the basis of own research and external information and found that emissions of Euro 5/6 vehicles generated by real driving on the road substantially exceed the emissions measured on the regulatory New European Driving Cycle (NEDC), in particular with respect to NOx emissions of diesel vehicles. ---|--- (4) | The type-approval emission requirements for motor vehicles have been gradually and significantly tightened through the introduction and subsequent revision of Euro standards. While vehicles in general have delivered substantial emission reductions across the range of regulated pollutants, this was not the case for NOx emissions from light passenger and commercial diesel vehicles. Actions for correcting this situation are therefore needed. ---|--- (5) | Defeat devices which reduce the level of emission control are prohibited by Regulation (EC) No 715/2007. The revelation related to the use of defeat devices in diesel vehicles and the subsequent national investigations have highlighted the need to strengthen the enforcement of the rules on defeat devices. Therefore it is appropriate to require a better supervision at type approval of the emissions control strategy applied by vehicles, building upon the principles already applied to heavy duty vehicles by Regulation (EC) No 595/2009 of the European Parliament and of the Council (4) and its implementing measures. ---|--- (6) | It is important to address the problem of NOx emissions from diesel vehicles in order to contribute to decreasing the current high levels of NO2 concentrations in ambient air, which are a major concern regarding human health. ---|--- (7) | The Commission has established in January 2011 a working group involving all interested stakeholders for developing a real-driving emissions (RDE) test procedure better reflecting emissions measured on the road. The Joint Research Centre of the Commission published two studies in 2011 and 2013 on the feasibility of on-road testing and assessment of other technical options. After thorough technical discussions, the option suggested in Regulation (EC) No 715/2007, i.e. the use of portable emission measurement systems (PEMS) and not-to-exceed (NTE) limits has been developed and implemented as complementary regulatory test procedure. ---|--- (8) | The first two parts of the RDE test procedure were introduced by Commission Regulations (EU) 2016/427 (5) and (EU) 2016/646 (6). It is now necessary to complement them with the provisions that allow taking into account the cold start, introduce the necessary protocol and limits for measuring particle number (PN) emissions, take proper account of regeneration events and make sure that provisions exist for hybrid electric vehicles, light commercial vehicles and small volume manufacturers. ---|--- (9) | Cold start is an important contributor to emissions from light passenger and commercial vehicles, being especially important in urban areas where most of the cold starts occur. Especially during winter, cold starts contribute significantly to the air pollution in cities and should therefore be regulated appropriately. In order to carry out a comprehensive and effective evaluation of the RDE is therefore necessary to include cold start into the evaluation of the urban and total trip emissions for both NOx and PN emissions using the existing evaluation methods. ---|--- (10) | Furthermore, in order to reduce the variability of testing conditions that could overshadow the contribution of cold start, special provisions should be laid down for the preconditioning of the vehicle and for driving during the cold-start period. ---|--- (11) | Since recent data indicate that there is still an issue in the EU with higher than expected vehicle emissions during hot start, it is necessary to perform a certain number of tests starting with a warm engine. ---|--- (12) | Regulation (EC) No 715/2007 set a temporary Euro 6 limit for the PN emissions of gasoline direct injection vehicles in order to allow appropriate lead time to integrate effective PN emissions control technologies, while stipulating that within three years from the mandatory Euro 6 dates, PN emissions should also be regulated under real driving conditions. ---|--- (13) | For this purpose, the Commission set up a task force in 2013 led by the Joint Research Centre with the aim of examining the newly developed PEMS equipment for measuring Particulate Mass and Particle Number and developing a measurement method for PN emissions in real-world driving, which should be included in this act. ---|--- (14) | The equipment for measuring the PN emissions was found to be reliable and well performing in a wide variety of conditions. It is expected that the equipment will improve with time. Furthermore, the emission profiles of ultrafine particles below the current measurement threshold of 23 nm are being investigated by the Commission to ensure that the measurement methods adequately cover real-world PN emissions. ---|--- (15) | Provisions should be laid down allowing also for hybrid electric vehicles to be evaluated. For plug-in hybrids the methodology should be adapted in order to ensure practicality and robustness of RDE provisions and to prepare a more complete evaluation method that can provide an accurate picture of the RDE emissions of plug-in hybrid vehicles and can thus be also included in local or national incentive schemes designed to promote the use of such vehicles. ---|--- (16) | Regeneration should be included in the evaluation of vehicle emissions under the RDE procedure. In order to ensure consistency of the RDE procedure with the Worldwide harmonised Light-duty vehicles Test Procedures (WLTP), it is appropriate to introduce a methodology which mandates the use of Ki-factors for excess emissions through regeneration and a related evaluation scheme. ---|--- (17) | Updating of the Ki-factors may be required to reflect changes in vehicle specification and technological progress. Revisions may be necessary to ensure that Ki-factors reflect the real-world occurrence and magnitude of regeneration events. ---|--- (18) | In order to ensure that light commercial vehicles with a speed limitation can also be tested under the RDE procedure, special provisions for the speeds boundaries should be included for those vehicles. ---|--- (19) | In order to allow independent small volume manufacturers with worldwide annual production of less than 10 000 units to adapt to the RDE procedure, they should be provided extra time to fully meet the NTE limits. However, it is appropriate to require them to monitor the NOx emissions during that period. ---|--- (20) | The ultra-small volume manufacturers should be exempted from the provisions of the RDE procedure. With a volume of less than 1 000 vehicles sold each year in the Union they contribute only marginally to the total emissions of the light passenger and commercial vehicle fleet. ---|--- (21) | Article 15(6) of Regulation (EU) 2017/1151 requires an examination of the legal provisions of Directive 2007/46/EC to be carried out following the introduction of the WLTP tests to ensure a fair treatment as regards vehicles already previously approved against the New European Driving Cycle (NEDC) test requirements. ---|--- (22) | That examination shows that the requirements of Regulation (EU) 2017/1151 should be applicable to newly registered vehicles, including those the types of which were previously approved on the basis of the NEDC tests laid down in Regulation (EC) No 692/2008. All new vehicles, whether their types were previously approved on the basis of the NEDC tests or whether their types are approved on the basis of the WLTP tests for the first time, must, in accordance with Article 15 of Regulation (EU) 2017/1151, fulfil the requirements of Annex IIIA to that Regulation as of 1 September 2019. For N1 vehicles of classes II and III and category N2 vehicles, the relevant date is 1 September 2020. ---|--- (23) | To ensure that the type/approval authorities are fully informed of the application of that rule, this application should be mentioned in Section II. 5, Remarks, of the EC-type-approval certificate, as set out in Appendix 4 of Annex I to Regulation (EU) 2017/1151. ---|--- (24) | The provisions regarding the obligation of manufacturers to declare the auxiliary emission strategies (AES) are clearly linked to the prohibition to use defeat devices. Therefore, the need for the approval authority to make a decision during type approval based on the risk assessment and health and environmental effects of the AES should be clearly stated in the legislation and the contents of the extended documentation package should enable that authority to make that decision. ---|--- (25) | In order to ensure transparency, to allow comparison with values measured during independent testing and to allow for the development of incentive schemes by local or national authorities, the obligation for the manufacturer to declare the maximum value of NOx emissions and the maximum PN in RDE tests in the certificate of conformity of each vehicle should be introduced. ---|--- (26) | The Commission should keep under review the provisions of the RDE test procedure and adapt those provisions to accommodate new vehicle and/or measurement technologies and to ensure their effectiveness. Similarly, the Commission should keep under annual review the appropriate level of the final conformity factors for gaseous pollutants and particle number in light of technical progress. It should in particular review the two alternative methods for evaluating PEMS emission data set out in Appendices 5 and 6 to Annex IIIA to Regulation (EU) 2017/1151 with a view to developing a single method. ---|--- (27) | It is therefore appropriate to amend Regulation (EU) 2017/1151 and Directive 2007/46/EC accordingly. ---|--- (28) | The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee — Motor Vehicles, ---|--- HAS ADOPTED THIS REGULATION: Article 1 Regulation (EU) 2017/1151 is amended as follows: (1) | Article 2 is amended as follows: | (a) | point 32 is replaced by the following: | ‘(32) | “small volume manufacturer” means a manufacturer whose worldwide annual production is less than 10 000 units for the year prior to the one for which the type approval is granted and: | (a) | is not part of a group of connected manufacturers; or ---|--- (b) | is part of a group of connected manufacturers whose worldwide annual production is less than 10 000 units for the year prior to the one for which the type approval is granted; or ---|--- (c) | is part of a group of connected manufacturers but operates its own production facilities and own design centre;’; ---|--- (b) | the following points 32a, 32b and 32c are added: | ‘(32a) | “own production facility” means a manufacturing or assembly plant used by the manufacturer for the purpose of manufacturing or assembling new vehicles for that manufacturer, including, where relevant, vehicles which are intended for export; ---|--- (32b) | “own design centre” means a facility in which the whole vehicle is designed and developed, and which is under the control and use of the manufacturer; ---|--- (32c) | “ultra-small-volume manufacturers” means a small volume manufacturer as defined in point (32) which has registrations of less than 1 000 in the Community for the year prior to the one the type approval is granted.’; ---|--- (2) | in Article 3(11) the following subparagraph is added: ‘The requirements of Annex IIIA shall not apply to emission type-approvals according to Regulation (EC) No 715/2007 granted to ultra-small-volume manufacturers.’; ---|--- (3) | Article 5 is amended as follows: | (a) | paragraph 11 is replaced by the following: ‘11.

General: The installation of the PEMS shall follow the instructions of the PEMS manufacturer and the local health and safety regulations. The PEMS should be installed as to minimise during the test electromagnetic interferences as well as exposure to shocks, vibration, dust and variability in temperature. The installation and operation of the PEMS shall be leak-tight and minimise heat loss. The installation and operation of PEMS shall not change the nature of the exhaust gas nor unduly increase the length of the tailpipe. To avoid the generation of particles, connectors shall be thermally stable at the exhaust gas temperatures expected during the test. It is recommended not to use elastomer connectors to connect the vehicle exhaust outlet and the connecting tube. Elastomer connectors, if used, shall have no contact with the exhaust gas to avoid artefacts at high engine load. 3.4.2. Permissible backpressure The installation and operation of the PEMS sampling probes shall not unduly increase the pressure at the exhaust outlet in a way that may influence the representativeness of the measurements. It is thus recommended that only one sampling probe is installed in the same plane. If technically feasible, any extension to facilitate the sampling or connection with the exhaust mass flow meter shall have an equivalent, or larger, cross sectional area than the exhaust pipe. If the sampling probes obstruct a significant area of the tailpipe cross-section, backpressure measurement may be requested by the Type Approval Authority. 3.4.3. Exhaust mass flow meter Whenever used, the exhaust mass flow meter shall be attached to the vehicle’s tailpipe(s) in accordance with the recommendations of the EFM manufacturer. The measurement range of the EFM shall match the range of the exhaust mass flow rate expected during the test. The installation of the EFM and any exhaust pipe adaptors or junctions shall not adversely affect the operation of the engine or exhaust after-treatment system. A minimum of four pipe diameters or 150 mm of straight tubing, whichever is larger, shall be placed at either side of the flow-sensing element. When testing a multi-cylinder engine with a branched exhaust manifold, it is recommended to position the exhaust mass flow meter downstream of where the manifolds combine and to increase the cross section of the piping such as to have an equivalent, or larger, cross sectional area from which to sample. If this is not feasible, exhaust flow measurements with several exhaust mass flow meters may be used, if approved by the Type Approval Authorities. The wide variety of exhaust pipe configurations, dimensions and exhaust mass flow rates may require compromises, guided by good engineering judgement, when selecting and installing the EFM(s). It is permissible to install an EFM with a diameter smaller than that of the exhaust outlet or the total cross-sectional area of multiple outlets, providing it improves measurement accuracy and does not adversely affect the operation or the exhaust after-treatment as specified in point 3.4.2. It is recommended to document the EFM set-up using photographs.’; ---|--- (c) | point 3.5 is replaced by the following: ‘3.5. Emissions sampling Emissions sampling shall be representative and conducted at locations of well-mixed exhaust where the influence of ambient air downstream of the sampling point is minimal.

The sampling probes shall be fitted at least 200 mm or three times the inner diameter of the exhaust pipe, whichever is larger, upstream of the point at which the exhaust exits the PEMS sampling installation into the environment. If the PEMS feeds back a flow to the tail pipe, this shall occur downstream of the sampling probe in a manner that does not affect during engine operation the nature of the exhaust gas at the sampling point(s). If the length of the sampling line is changed, the system transport times shall be verified and if necessary corrected. If the engine is equipped with an exhaust after-treatment system, the exhaust sample shall be taken downstream of the exhaust after-treatment system. When testing a vehicle with a branched exhaust manifold, the inlet of the sampling probe shall be located sufficiently far downstream so as to ensure that the sample is representative of the average exhaust emissions of all cylinders. In multi-cylinder engines, having distinct groups of manifolds, such as in a “V” engine configuration, the sampling probe shall be positioned downstream of where the manifolds combine. If this is technically not feasible, multi-point sampling at locations of well-mixed exhaust may be used, if approved by the Type Approval Authority. In this case, the number and location of sampling probes shall match as far as possible those of the exhaust mass flow meters. In case of unequal exhaust flows, proportional sampling or sampling with multiple analysers shall be considered. If particles are measured, the exhaust shall be sampled from the centre of the exhaust stream. If several probes are used for emissions sampling, the particle sampling probe should be placed upstream of the other sampling probes. The particle sampling probe should not interfere with the sampling of gaseous pollutants. The type and specifications of the probe and its mounting shall be documented in detail. If hydrocarbons are measured, the sampling line shall be heated to 463 ± 10 K (190 ± 10 °C). For the measurement of other gaseous components with or without cooler, the sampling line shall be kept at a minimum of 333 K (60 °C) to avoid condensation and to ensure appropriate penetration efficiencies of the various gases. For low pressure sampling systems, the temperature can be lowered corresponding to the pressure decrease provided that the sampling system ensures a penetration efficiency of 95 % for all regulated gaseous pollutants. If particles are sampled and not diluted at the tailpipe, the sampling line from the raw exhaust sample point to the point of dilution or particle detector shall be heated to a minimum of 373 K (100 °C). The residence time of the sample in the particle sampling line shall be less than 3 s until reaching first dilution or the particle detector. All parts of the sampling system from the exhaust pipe up to the particle detector, which are in contact with raw or diluted exhaust gas, shall be designed to minimize deposition of particles. All parts shall be made from antistatic material to prevent electrostatic effects.’; ---|--- (d) | points 4.2. and 4.3. are replaced by the following: ‘4.2.

Before and directly after “ignition on”, it shall be confirmed that all necessary parameters are recorded by the data logger. 5.2. Test Sampling, measurement and recording of parameters shall continue throughout the on-road test of the vehicle. The engine may be stopped and started, but emissions sampling and parameter recording shall continue. Any warning signals, suggesting malfunctioning of the PEMS, shall be documented and verified. If any error signal(s) appear during the test, the test shall be voided. Parameter recording shall reach a data completeness of higher than 99 %. Measurement and data recording may be interrupted for less than 1 % of the total trip duration but for no more than a consecutive period of 30 s solely in the case of unintended signal loss or for the purpose of PEMS system maintenance. Interruptions may be recorded directly by the PEMS but it is not permissible to introduce interruptions in the recorded parameter via the pre-processing, exchange or post-processing of data. If conducted, auto zeroing shall be performed against a traceable zero standard similar to the one used to zero the analyser. It is strongly recommended to initiate PEMS system maintenance during periods of zero vehicle speed. 5.3.

It is permissible that the particle detector also pre-conditions the aerosol. The sensitivity of the analysers to shocks, vibration, aging, variability in temperature and air pressure as well as electromagnetic interferences and other impacts related to vehicle and analyser operation shall be limited as far as possible and shall be clearly stated by the equipment manufacturer in its support material. The PN analyser shall only be used within its manufacturer’s declared parameters of operation. Figure 1 Example of a PN analyser setup: Dotted lines depict optional parts. EFM = Exhaust mass Flow Meter, d = inner diameter, PND = Particle Number Diluter. The PN analyser shall be connected to the sampling point via a sampling probe which extracts a sample from the centreline of the tailpipe tube. As specified in point 3.5 of Appendix 1, if particles are not diluted at the tailpipe, the sampling line shall be heated to a minimum temperature of 373 K (100 °C) until the point of first dilution of the PN analyser or the particle detector of the analyser. The residence time in the sampling line shall be less than 3 s. All parts in contact with the sampled exhaust gas shall be always kept at a temperature that avoids condensation of any compound in the device. This can be achieved, e.g. by heating at a higher temperature and diluting the sample or oxidizing the (semi)volatile species. The PN analyser shall include a heated section at wall temperature ≥ 573 K. The unit shall control the heated stages to constant nominal operating temperatures, within a tolerance of ± 10 K and provide an indication of whether or not heated stages are at their correct operating temperatures.

The efficiency requirements will need to be adapted, in order to make sure that the efficiency of the PN analysers remains consistent with the margin PN. The material should be thermally stable soot-like (e.g. spark discharged graphite or diffusion flame soot with thermal pre-treatment). If the efficiency curve is measured with a different aerosol (e.g. NaCl), the correlation to the soot-like curve must be provided as a chart, which compares the efficiencies obtained using both test aerosols. The differences in the counting efficiencies have to be taken into account by adjusting the measured efficiencies based on the provided chart to give soot-like aerosol efficiencies. The correction for multiply charged particles should be applied and documented but shall not exceed 10 %. These efficiencies refer to the PN analysers with the sampling line. The PN analyser can also be calibrated in parts (i.e. the pre-conditioning unit separately from the particle detector) as long as it is proven that PN analyser and the sampling line together fulfil the requirements of Table 3a. The measured signal from the detector shall be > 2 times the limit of detection (here defined as the zero level plus 3 standard deviations). 6.3. Linearity requirements The PN analyser including the sampling line shall fulfil the linearity requirements of point 3.2 in Appendix 2 using monodisperse or polydisperse soot-like particles.

Alternatively, a particle number system compliant with UNECE Regulation 83. In addition the differences of the PN analyser from the reference instrument at all points checked (except the zero point) shall be within 15 % of their mean value. At least 5 points equally distributed (plus the zero) shall be checked. The maximum checked concentration shall be the maximum allowed concentration of the PN analyser. If the PN analyser is calibrated in parts, then the linearity can be checked only for the PN detector, but the efficiencies of the rest parts and the sampling line have to be considered in the slope calculation. 6.4. Volatile removal efficiency The system shall achieve > 99 % removal of ≥ 30 nm tetracontane (CH3(CH2)38CH3) particles with an inlet concentration of ≥ 10 000 particles per cubic-centimetre at the minimum dilution. The system shall also achieve a > 99 % removal efficiency of polydisperse alcane (decane or higher) or emery oil with count median diameter > 50 nm and mass > 1 mg/m3. The volatile removal efficiency with tetracontane and/or polydisperse alcane or oil have to be proven only once for the instrument family.
