THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

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)(1), and in particular Article 39(2), (6) and (7) thereof.                        

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(2), and in particular Articles 4(3), 5(4) and 6(2), and Article 12 thereof,                        

Whereas:

(1)Regulation (EC) No 595/2009 establishes emission limits and common technical requirements for the type-approval of motor vehicles                              and replacement parts with regard to their emissions, laying down rules for in-service conformity, on-board diagnostic (OBD)                              systems and measurement of fuel consumption.

(2)In order to raise the level of environmental performance of the vehicles, a particulate number limit for positive ignition                              engines should be introduced.

(3)The legislation on type-approval of motor vehicles and engines with respect to emissions from heavy-duty vehicles (Euro VI)                              needs to be adapted to technical progress. Therefore, the requirements for type-approval and in-service conformity of engines                              and vehicles using dual-fuel technologies need to be provided for. Additional matters relating to the type-approval of engines                              using gaseous fuels should also be addressed.

(4)Commission Regulation (EU) No 582/2011(3) requires that the on-board diagnostic (OBD) threshold limit (OTL) for carbon monoxide emissions be specified.

(5)In the case of heavy-duty vehicles with a technically permissible maximum laden mass not exceeding 7,5 tons, it is appropriate                              to allow that OBD systems fitted into those vehicles be partially developed in accordance with the OBD rules applicable to                              light-duty vehicles, without undermining their level of environmental performance.

(6)Regulation (EU) No 582/2011 refers repeatedly to the regulations of the United Nations Economic Commission for Europe (UNECE),                              and in particular to UNECE Regulation No 49(4), regarding the technical requirements to be followed at type-approval and in-service conformity by Member States, manufacturers                              and technical services. Since a 06 series of amendments of UNECE Regulation No 49 has been adopted by the World Forum for                              Harmonization of Vehicle Regulations (WP.29), it is necessary to update the references of Euro VI to UNECE Regulation No 49.

(7)Some additional requirements need to be laid down in order to ensure the equivalence between an EC type-approval and the type-approval                              provided for by UNECE Regulation No 49.

(8)The oil temperature of the engine must be expressed in Kelvin. It is therefore necessary to amend Annex VIII to Directive                              2007/46/EC.

(9)Directive 2007/46/EC, Regulation (EC) No 595/2009 and Regulation (EU) No 582/2011 should therefore be amended accordingly.

(10)In order to provide Member States and manufacturers with sufficient lead time for the adaptation of their respective information                              systems, it is appropriate to delay the application of the amendments related to the certificate of conformity.

(11)The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee — Motor Vehicles,

Annexes I, II and IV to XIV to Regulation (EU) No 582/2011 are amended as follows:

Annex I is amended as follows

point 1.1.1 is replaced by the following:

The parent engine shall meet the requirements of this Regulation on the appropriate reference fuels specified in Annex IX.                                                   Specific requirements shall apply to engines fuelled with natural gas/biomethane, including dual-fuel engines, as laid down                                                   in point 1.1.3’;                                             

point 1.1.3 is replaced by the following:

In the case of natural gas/biomethane fuelled engines, including dual-fuel engines, the manufacturer shall demonstrate the                                                   parent engines capability to adapt to any natural gas/biomethane composition that may occur across the market. This demonstration                                                   shall be carried out in accordance with this Section and, in the case of dual-fuel engines, also in accordance with the additional                                                   provisions regarding the fuel adaptation procedure set out in paragraph 6.4 of Annex 15 to UNECE Regulation No 49.                                             

In the case of compressed natural gas/biomethane (CNG) there are generally two types of fuel, high calorific fuel (H-gas)                                                   and low calorific fuel (L-gas), but with a significant spread within both ranges; they differ significantly in their energy                                                   content expressed by the Wobbe Index and in their λ-shift factor (Sλ). Natural gases with a λ-shift factor between 0,89 and 1,08 (0,89 ≤ Sλ ≤ 1,08) are considered to belong to H-range, while natural gases with a λ-shift factor between 1,08 and 1,19 (1,08 ≤ Sλ ≤ 1,19) are considered to belong to L-range. The composition of the reference fuels reflects the extreme variations of Sλ.                                             

The parent engine shall meet the requirements of this Regulation on the reference fuels GR (fuel 1) and G25 (fuel 2), as specified in Annex IX, without any manual readjustment to the engine fuelling system between the two tests (self-adaptation                                                   is required). One adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After                                                   the adaptation run, the engine shall be cooled down in accordance with paragraph 7.6.1 of Annex 4 to UNECE Regulation No 49.                                             

In the case of liquefied natural gas/biomethane (LNG) the parent engine shall meet the requirements of this Regulation on                                                   the reference fuels GR (fuel 1) and G20 (fuel 2), as specified in Annex IX, without any manual readjustment to the engine fuelling system between the two tests (self-adaptation                                                   is required). One adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After                                                   the adaptation run, the engine shall be cooled down in accordance with paragraph 7.6.1 of Annex 4 to UN/ECE Regulation No 49.’;                                             

point 1.1.4 is replaced by the following:

In the case of an engine fuelled with CNG which is self-adaptive for the range of H-gases on the one hand and the range of                                                   L-gases on the other hand, and which switches between the H-range and the L-range by means of a switch, the parent engine                                                   shall be tested on the relevant reference fuel as specified in Annex IX for each range, at each position of the switch. The                                                   fuels are GR (fuel 1) and G23 (fuel 3) for the H-range of gases and G25 (fuel 2) and G23 (fuel 3) for the L-range of gases. The parent engine shall meet the requirements of this Regulation at both positions of                                                   the switch without any readjustment to the fuelling between the two tests at each position of the switch. One adaptation run                                                   over one WHTC hot cycle without measurement is permitted after the change of the fuel. After the adaptation run the engine                                                   shall be cooled down in accordance with paragraph 7.6.1 of Annex 4 to UNECE Regulation No 49.’;                                             

points 1.1.5 and 1.1.6 are replaced by the following:

In the case of natural gas/biomethane engines, the ratio of the emission results “r” shall be determined for each pollutant                                                   as follows:                                             

or,                                             

and,                                             

In the case of LPG the manufacturer shall demonstrate the parent engines capability to adapt to any fuel composition that                                                   may occur across the market.                                             

In the case of LPG there are variations in C3/C4 composition. These variations are reflected in the reference fuels. The parent engine shall meet the emission requirements                                                   on the reference fuels A and B as specified in Annex IX without any readjustment to the fuelling between the two tests. One                                                   adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After the adaptation                                                   run the engine shall be cooled down in accordance with paragraph 7.6.1 of Annex 4 to UNECE Regulation No 49.’;                                             

points 1.2 and 1.2.1 are replaced by the following:

Requirements on restricted fuel range type-approval in case of engines fuelled with natural gas/biomethane or LPG, including                                                   dual-fuel engines                                             

A restricted fuel range type-approval shall be granted subject to the requirements specified in points 1.2.1 to 1.2.2.2.

The parent engine shall be tested on the relevant reference fuel, as specified in Annex IX, for the relevant range. The fuels                                                            are GR (fuel 1) and G23 (fuel 3) for the H-range of gases and G25 (fuel 2) and G23 (fuel 3) for the L-range of gases. The parent engine shall meet the requirements of this Regulation without any readjustment                                                            to the fuelling between the two tests. One adaptation run over one WHTC hot cycle without measurement is permitted after the                                                            change of the fuel. After the adaptation run the engine shall be cooled down in accordance with paragraph 7.6.1 of Annex 4                                                            to UNECE Regulation No 49.’;                                                      

points 1.2.2, 1.2.2.1 and 1.2.2.2 are replaced by the following:

Exhaust emissions type-approval of an engine running on natural gas/biomethane or LPG and designed for operation on one specific                                                   fuel composition.                                             

The parent engine shall meet the emission requirements on the reference fuels GR and G25 in the case of CNG, on the reference fuels GR and G20 in the case of LNG, or on the reference fuels A and B in the case of LPG, as specified in Annex IX. Fine-tuning of the fuelling                                                   system is allowed between the tests.
