GRPE | Session 77 | 4-8 Jun 2018

9. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/15 and ECE/TRANS/WP.29/GRPE/2018/17 aimed at adapting the provisions in UN Regulation No. 83 and UN Regulation No. 101 to allow the usage of WLTP-based Ki and Deterioration Factor (DF) factors as well as On-Board Diagnostics (OBD) demos. The experts from EC and UK proposed minor corrections to ECE/TRANS/WP.29/GRPE/2018/15 that GRPE adopted as reproduced in Annex VI. GRPE also adopted ECE/TRANS/WP.29/GRPE/2018/17.

10. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/18 aimed at modifying the Constant Volume Sampling system temperature sensor time response requirement in UN Regulation No. 83. The Chair of GRPE requested clearer provisions to align with the work performed under the IWG on WLTP. The Expert from OICA presented informal document GRPE-77-31 amending ECE/TRANS/WP.29/GRPE/2018/18. GRPE adopted the proposal as reproduced in Annex VII.

12. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2018/13, Annexes IV, VI and VII and Addendum 1 to the report to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as draft Supplements 2, 1, 12, 12 and 18 to the 03, the 04, the 05, the 06 and the 07 series of amendments to UN Regulation No. 83 respectively.

11. The expert from EC presented GRPE-76-32 proposing to amend the definitions for bi-fuel vehicles and align these definitions with those in UN Global Technical Regulation (UN GTR) No. 15. GRPE supported the intention of the proposal.

12. GRPE agreed to reconsider at the June 2018 session GRPE-76-03, GRPE-76-04 and GRPE-76-32. GRPE requested the experts from OICA and EC to combine the documents in one formal document.
