Proposal for amendments to Regulation No. 67
Download in .pdf format

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.
