9. (b) UN Regulation No. 110 (CNG and LNG vehicles)
|
37. Recalling the discussion of GRSG at its previous session, the expert from Italy introduced ECE/TRANS/WP.29/GRSG/2018/16 to amend Annex 3A of the Regulation on the test requirements for Compressed Natural Gas (CNG) cylinders to avoid structural failures during their service life. The expert from NGV Global proposed some further clarifications (GRSG-115-06) and a new definition on “certified cylinder”. The proposals received general support.

38. The expert from OICA presented ECE/TRANS/WP.29/GRSG/2018/13 to adapt the text of the Regulation to the current technology on the gas flow adjustor in the carburettor or injector. GRSG noted a number of comments and proposals for amendments.

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.

39. The expert from OICA introduced GRSG-115-18-Rev.2 amending the Regulation with respect to the inspection requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2018/16, ECE/TRANS/WP.29/GRSG/2018/13 and GRSG-115-18-Rev.2 as reproduced in Annex III to this report. The secretariat was requested to submit the proposals to WP.29 and AC.1 as draft Supplement 2 to the 03 series of amendments to UN Regulation No. 110 for consideration at their March 2019 sessions.

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.”

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: | 24.22. | As from the official date of entry into force of the 04 series of amendments, no Contracting Party applying this Regulation shall refuse to grant or refuse to accept type approvals under this Regulation as amended by the 04 series of amendments. | | 24.23. | As from 1 September 2022, Contracting Parties applying this Regulation shall not be obliged to accept type approvals to the preceding series of amendments, first issued after 1 September 2022. | | 24.24. | Until 1 September 2024, Contracting Parties applying this Regulation shall accept type approvals to the preceding series of amendments, first issued before 1 September 2022. | | 24.25. | As from 1 September 2024, Contracting Parties applying this Regulation shall not be obliged to accept type approvals issued to the preceding series of amendments to this Regulation. |

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.

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”.

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.
