Proposal to require, in instances where ogive protective covers are fitted to a cylinder, that the covers be removed before conducting the impact damage (drop) test.

Proposal prepared by OICA per decisions by the task force on gas-fuelled vehicle regulations to resolve issues associated with periodic requalification of CNG cylinders. The proposal amends Annexes 3A and 3B, particularly to state “Contracting Parties requiring a more frequent (than every 48 months) or more stringent periodic requalification of cylinders may do so in accordance with the national or regional requirements.”

Proposal to allow the use of a generator fueled by the vehicle gaseous fuel system that provides electricity to run accessories (e.g., overnight power in sleeper cabs, to maintain battery charge during high electrical power use with loading or lifting equipment). This proposal would allow for the use of LNG/CNG from vehicle fuel tanks and thereby reduce the potential need to vent gas into the air in response to pressure buildup due to warming over time by using the gas to power other devices and equipment.

Proposal to introduce requirements for CNG compressor and CNG accumulator components designed to maintain stable pressure in fuel systems.

This proposal introduces transitional provisions into UN Regulation No. 110 should the proposals in document GRSG/2018/11 be adopted. GRSG/2018/11 would change the technical requirements for vehicles equipped with CNG compressors and/or accumulators and therefore would transitional provisions be applicable.

Proposal to amend and clarify the need for a gas flow adjuster under UN R110 with regard to the use of carburetors and fuel injectors. A gas flow adjuster is not necessary when an electronic fuel injection system manages the air/fuel mixture and therefore should be removed from paragraph 18.3.1. An adjuster is needed when air/fuel mixture runs via a carburetor and therefore should be added to paragraph 18.3.2.
