Text prepared by the European Association of Automotive Suppliers (CLEPA) to introduce into Regulations Nos. 67 and 110 type approval provisions for “valve control at stop-start”. This proposal allows the tank valves to stay open in an active stop-start phase for CNG/LPG with stop-start engines.
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."
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.
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.
