This agenda item relates to UN R83 Motor Vehicle Emissions.
Working Party on Pollution and Energy | Session 68 | 7-10 Jan 2014

18. The expert from the EC introduced ECE/TRANS/WP.29/GRPE/2014/2 and a corrigendum contained in GRPE-68-08, outlining a proposal to amend UN Regulation No. 83 in order to align its requirements with those of the European Union Regulation (EC) Nos. 715/2007, 692/2008, 566/2011, 459/2012 and 630/2012.

19. The expert from Germany stressed the need to combine safety-related provisions on H2NG flex fuel vehicles with the provisions included in the proposal. The expert from France supported this statement. She underlined that, while Europe has a whole vehicle type approval procedure in place and capable to ensure that the safety issues are also taken into consideration, this is not the case in Contracting Parties that are not subject to the European homologation procedure.

20. The expert from OICA introduced GRPE-68-07-Rev.1, proposing to modify ECE/TRANS/WP.29/GRPE/2014/2 in order to avoid misinterpretations in the practical implementation of the UN Regulation. GRPE-68-07-Rev.1 contains modifications regarding the inclusion of: i) pure electric vehicles and hydrogen fuel cell vehicles in the table on the application of test requirements for type approval and extensions; ii) requirements of UN Regulation No. 85 in UN Regulation No. 83; iii) aspects related with real driving conditions (currently being discussed in the EU); iv) a limit of validity of type-approvals clause and v) the concept of H2NG flex fuel vehicles. It also addresses the requirements for daytime running lamps and for vehicles equipped with compression-ignition engines. The expert from OICA underlined that GRPE-68-07-Rev.1 addresses the concerns on H2NG flex fuel vehicles raised by the experts from Germany and France.

21. The expert from Japan supported GRPE-68-07-Rev.1. The expert from the EC agreed to remove the references to the hydrogen and natural gas (H2NG) fuel from ECE/TRANS/WP.29/GRPE/2014/2. The expert from Italy agreed with this solution, but he also underlined the need to consider H2NG in future developments of UN Regulation No. 83 and other regulatory texts. Following a comment by the expert from the United Kingdom, a reference to vehicles required to be equipped with daytime running lamps, originally included in the OICA proposal (amending section 3.2.7. of Annex 4a), was removed from GRPE-68-07-Rev.1.

22. GRPE adopted ECE/TRANS/WP.29/GRPE/2014/2, as amended by GRPE-68-08 and GRPE-68-07-Rev.1 (without the amendment of section 3.2.7. of Annex 4a), requesting the secretariat to combine these modifications and submit the resulting text to WP.29 and AC.1 for consideration at their June 2014 sessions as the 07 series of amendments to UN Regulation No. 83.

23. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2014/9, updating the On-Board Diagnostics (OBD) requirements in ECE/TRANS/WP.29/GRPE/2014/2 (07 series of amendments to UN Regulation No. 83). He also explained that ECE/TRANS/WP.29/GRPE/2014/8 contains similar changes for the 06 series of amendments. The expert from CLEPA mentioned that the consequences of these proposals are currently being scrutinized. The expert from the EC expressed the need to analyse the proposals in further detail, also stating that the position of all stakeholders affected by these modifications needs to be taken into account. The expert from Germany also expressed concerns on the content of the proposals. The expert from OICA sought the GRPE advice for their future consideration. GRPE endorsed the invitation by the expert from the EC to consider ECE/TRANS/WP.29/GRPE/2014/8 and ECE/TRANS/WP.29/GRPE/2014/9 in an expert meeting with interested stakeholders with the aim to find a compromise. GRPE also requested the expert from the EC to provide information on the development of this discussion in the June 2014 session of GRPE.

26. The expert from the EC introduced ECE/TRANS/WP.29/GRPE/2014/5, a proposal to align the requirements of UN Regulation No. 101 with the latest changes in the regulatory framework of the European Union in relation to the specifications of new reference fuels E10 and B7, explaining that this is related with the provisions of ECE/TRANS/WP.29/GRPE/2014/2.

World Forum for the Harmonization of Vehicle Regulations | Session 163 | 24-27 Jun 2014

No objections to the proposals which are passed for consideration to adopt during the AC.1 session.

57. Agenda item 4.7.3, Regulation No. 83, ECE/TRANS/WP.29/2014/41, correct Annex 4a, Appendix 7, paragraph 4.1.2., to read:

"4.1.2. Tyres

The choice of tyres shall be based on the rolling resistance. The tyres with the highest rolling resistance shall be chosen, measured according to ISO 28580.

If there are more than three tyre rolling resistances, the tyre with the second highest rolling resistance shall be chosen.

The rolling resistance characteristics of the tyres fitted to production vehicles shall reflect those of the tyres used for type approval."
