UN R110: Proposal for amendments to reduce venting via new technologies
Document GRSG-114-06/Rev.1
12 April 2018

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.

9. (b) | UN Regulation No. 110 (CNG and LNG vehicles)

42. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2018/12 to insert new requirements for vehicle gas systems to provide gaseous fuel to a generator that would provide electrical power to accessories or other systems on the vehicle. GRSG noted general support on the proposal. GRSG adopted ECE/TRANS/WP.29/GRSG/2018/12, as amended below. The secretariat was requested to submit the proposal to WP.29 and AC.1 as part (see para. 41) of draft 04 series of amendments to UN Regulation No. 110 for consideration at their March 2019 sessions.

Through the whole proposal, replace the words “second engine” by “secondary engine”.

6. (b) | Amendments to gas-fuelled vehicle regulations: Regulation No. 110 (CNG and LNG vehicles)

34. The expert from the Netherlands introduced GRSG-114-06 to allow the use of gas fuelled generators to provide electrical power for accessories or other vehicle systems. The expert from the United Kingdom suggested simplifying the text and referring to a secondary engine only. GRSG noted the general support for GRSG-114-06-Rev.1 and requested the secretariat to circulate it with an official symbol at the next GRSG session for a final review.
