Proposal to introduce type-approval provisions for fuel selection systems into the regulation on compressed natural gas-powered vehicles.

Proposal to introduce type approval provisions for “valve control at stop-start”.

These provisions are similar to those proposed for UN Regulation No. 67

Proposal to clarify the text concerning automatic valves in the draft Supplement 1 to the 01 series of amendments to Regulation No. 110 (document WP.29/2013/101).
