Proposed revisions to the CLEPA to introduce into Regulations Nos. 67 and 110 type approval provisions for “valve control at stop-start”. The CLEPA proposal would allow the tank valves to stay open in an active stop-start phase for CNG/LPG with stop-start engines.
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.
