Meeting Session(s)

GRPE | Session 74 | 10-13 Jan 2017 (Agenda item 3. (b) | Light vehicles: Global Technical Regulation No. 15 on Worldwide harmonized Light vehicles Test Procedures (WLTP))

17. The expert from EC presented ECE/TRANS/WP.29/GRPE/2017/3 on a draft new GTR on evaporative emission test procedure for WLTP (WLTP EVAP). He clarified that the current proposal focuses on the evaporative emissions that can occur during parking events, so running losses and refuelling emissions are out of the scope for the time being. He explained that the test procedure for sealed fuel tank systems will be introduced at a later stage. He introduced the technical report on the development of the draft new GTR (GRPE-74-04).

19. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/3 and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions as a new draft GTR on evaporative emission test procedure for WLTP (WLTP EVAP). GRPE also adopted the technical report (GRPE-74-04) as reproduced in Addendum 2 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions.

Summary

Text prepared by the Evaporative emissions Task Force of the WLTP informal working group in line with Phase 2 of its mandate (ECE/TRANS/WP.29/AC.3/44). The WLTP referred to a first draft of this proposal (GRPE-73-12) at the seventy-third session of GRPE (see report ECE/TRANS/WP.29/GRPE/73, para. 12).
