Proposal to introduce type-approval provisions for “valve control at stop-start” into the regulation on LPG equipment. The proposal would allow tank valves stay open in a commanded stop-start phase as it is the case for the idling phase of non-stop-start vehicles. These provisions are similar to those for UN R110 on CNG vehicles.
35. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/24 proposing to insert into UN Regulation No. 67 new provisions for “valve control at stop-start”. GRSG adopted the document, as amended below, and requested the secretariat to submit the amendments to WP.29 and AC.1 for consideration at their March 2014 sessions as draft Supplement 14 to the 01 series of amendments to UN Regulation No. 67.
Annex 3, new paragraph 4.7., subparagraph (c), amend to read:
“(c) 1,000,000 cycles (mark “H3”) if, in addition to (a) or (b), the engine also shuts off automatically when the accelerator pedal is released."
34. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11, ECE/TRANS/WP.29/GRSG/2013/12 and GRSG-104-18 proposing to introduce into UN Regulation No. 67 type approval provisions for fuel selection systems respectively for “valve control at the stop-start function”. Recalling the discussion on the same subject under agenda item 8 on UN Regulation No. 110 (see paras. 38 and 39 below), GRSG agreed to resume consideration on this matter at its next session. In this respect, the Chair invited the expert from CLEPA to prepare, if necessary, updated proposals.
39. The expert from CLEPA also proposed to introduce type approval provisions for “valve control at the stop-start function” into UN Regulation No. 110 (ECE/TRANS/WP.29/GRSG/2013/12). The expert from OICA presented GRSG-104-19 improving the proposed text. GRSG agreed in principle on the both proposals, but preferred again to refer the proposal to GFV for detailed review. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
