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.

33. The expert from the Netherlands presented GRSG-114-03 on new requirements for components used in LNG/CNG systems such as the “CNG accumulator” and the “CNG compressor”. GRSG noted no objection on the proposal and agreed to consider it in detail at its next session on the basis of an official document.

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.

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. The expert from OICA stated that the proposal by the Netherlands result in changes of the level of the technical requirements for vehicles equipped with CNG compressors and/or accumulators. He introduced GRSG-115-19 proposing to submit the new requirements as a new 04 series of amendments to UN Regulation No. 110 together with appropriate transitional provisions.

41. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2018/11, as amended below. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft 04 series of amendments to UN Regulation No. 110 for consideration at their March 2019 sessions.

Insert new paragraphs 24.22. to 24.25. (Transitional provisions), to read:

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

103. The World Forum considered the draft amendments under agenda items 4.8.1 to 4.8.8 and recommended their submission to AC.1 for voting, subject to the following corrections:

104. For agenda item 4.8.6, document ECE/TRANS/WP.29/2019/13, para. 6.12, the last sentence “Manufacturers are advised …… Appendix H to this annex.” shall be deleted.

105. The Chair of GRSG presented the amendment proposal in ECE/TRANS/WP.29/2019/16 under agenda item 4.8.9, to amend UN Regulation No. 110 with the following correction in annex 1A, add: “Items 1.2.4.5.15.4. to 1.2.4.5.15.6., shall be deleted.”.
