COMMISSION REGULATION (EU) 2019/1939

of 7 November 2019

amending Regulation (EU) No 582/2011 as regards Auxiliary Emission Strategies (AES), access to vehicle OBD information and vehicle repair and maintenance information, measurement of emissions during cold engine start periods and use of portable emissions measurement systems (PEMS) to measure particle numbers, with respect to heavy duty vehicles

(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 Articles 4(3), 5(4), 6(2) and 12 thereof.

Whereas:

| (1) | The rules for declaring and assessing Auxiliary Emission Strategies (AES) were recently changed for light passenger and commercial vehicles by Commission Regulation (EU) 2017/1151 (2). The provisions already established in Commission Regulation (EU) No 582/2011 (3) for heavy duty vehicles should be aligned for the sake of consistency. |

(1)

The rules for declaring and assessing Auxiliary Emission Strategies (AES) were recently changed for light passenger and commercial vehicles by Commission Regulation (EU) 2017/1151 (2). The provisions already established in Commission Regulation (EU) No 582/2011 (3) for heavy duty vehicles should be aligned for the sake of consistency.

| (2) | In-service conformity testing represents one of the building blocks of the vehicle type-approval procedure and allows the performance of emission control systems to be verified throughout a vehicle’s useful life. Commission Regulation (EU) No 582/2011 requires the tests to be performed by means of a portable emissions measurement system (PEMS), which assesses emissions under normal conditions of use. The PEMS approach is equally used to check off-cycle emissions during type-approval. |

Commission Regulation (EU) No 582/2011 requires the tests to be performed by means of a portable emissions measurement system (PEMS), which assesses emissions under normal conditions of use. The PEMS approach is equally used to check off-cycle emissions during type-approval.

| (3) | The emissions performance of heavy duty vehicles in the period following a cold engine start is currently not assessed as part of the type-approval demonstration test or the in-service conformity test. Following a monitoring exercise when data from type-approval and in-service conformity tests were collected and analysed, it was found that significant amounts of the total NOx emitted were excluded from the analysis as a result of not assessing the cold engine start period. In order to represent real world emissions better, the measurement procedure should therefore be revised to include measurement of pollutant emissions during the cold engine start period. |

| (4) | Particle number measurements using PEMS have been successfully implemented under the emissions type-approval rules for light passenger and commercial vehicles (4). Following a pilot study by the Commission’s Joint Research Centre in which an analysis was performed on the portable particle number equipment for heavy duty vehicles, it is considered appropriate to introduce a similar requirement in the emissions type-approval rules for heavy duty vehicles. The Commission will be obliged under Regulation (EC) No 595/2009 to keep the level of the final conformity factor for particle number emissions under review, taking into account technical progress. |

| (5) | The Commission recognises that vehicles equipped with a spark-ignition engine or a dual-fuel engine fuelled with gas from Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) or Liquefied Petroleum Gas (LPG) may require technical adaptations to comply with the particle number conformity factor. In order to ensure a sufficient lead time to allow manufacturers of gas engines to modify their products in accordance with the requirements laid down by this Regulation, a transitional period should be permitted for compliance with the maximum allowed conformity factor for vehicles equipped with such engines. |

| (6) | The requirements introduced by this Regulation for in-service conformity testing should not apply retroactively to engines and vehicles which were type-approved before introduction of those requirements. Therefore, the amendments set out in Annexes I, II and III to this Regulation should only apply to the in-service conformity testing of new types of engine or vehicle, in other words to engines or vehicles which are type-approved in accordance with the amendments introduced by this Regulation. |

| (7) | The rules on access to vehicle OBD information and vehicle repair and maintenance information have been incorporated into Regulation (EU) 2018/858 of the European Parliament and of the Council (5), which applies from 1 September 2020. Therefore, the provisions in Regulation (EU) No 582/2011 relating to access to such information should be omitted with effect from that date. |
