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.
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.
