Proposal to introduce type-approval provisions for fuel selection systems and for “valve control at stop-start”. The former focuses on ensuring that dual fuel systems prevent fuel intended for one system from flowing into the other system. The latter would let the tank valves stay open in a commanded stop-start phase as is the case for the idling phase of vehicles not equipped with start-stop systems.

GRSG | Session 107 | 30 Sep-3 Oct 2014

24. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2014/29 to regulate the direction of discharging the pressure relief devices of CNG containers. He explained that the proposal addressed the safety of not only the vehicle occupants but also the surrounding area. The expert from IANGV introduced GRSG-107-35, which suggests that the discussion should be deferred until after the outcome of the ongoing research conducted in the United States of America on this matter. The experts from France, Germany, Sweden and OICA questioned the impact of this proposal on design of vehicle categories M1 and N1. GRSG agreed to resume discussion on this subject at its May 2015 session on the basis of a revised document.

GRSG | Session 105 | 8-11 Oct 2013

37. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/25. GRSG adopted the document and requested the secretariat to submit the proposing type approval provisions for fuel selection systems amendments to WP.29 and AC.1 for consideration at their March 2014 sessions as draft Supplement 2 to the 01 series of amendments to UN Regulation No. 110.

38. On the same subject than that mentioned under para. 35 above (new provisions for “valve control at stop-start”), the expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/26 proposing similar amendments to UN Regulation No. 110. GRSG adopted the document, as reproduced in Annex III of the session report, and requested the secretariat to submit the amendments to WP.29 and AC.1 for consideration at their March 2014 sessions as part (see para. 37 above) of draft Supplement 2 to the 01 series of amendments to UN Regulation No. 110.
