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.

Proposal to introduce new provisions into Regulation No. 67 for preventing the flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa in order to address a potential safety risk in bi-fuel or dual-fuel vehicles.
