Proposal to introduce requirements for CNG compressor and CNG accumulator components designed to maintain stable pressure in fuel systems. See also documents GRSG-113-24 and 25 from the previous GRSG session.
40. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2018/11 on new requirements on “CNG compressor” and “CNG accumulator” components used in LNG/CNG systems.

41. The expert from the Netherlands presented GRSG-113-24 and GRSG-113-25 justifying the need to introduce in the Regulation new requirements for components used in LNG/CNG systems such as the “CNG accumulator” and the “CNG compressor”. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the expert from the Netherlands.
