6. (b) Amendments to gas-fuelled vehicle regulations: Regulation No. 110 (CNG and LNG vehicles
|
38. The expert from ISO introduced GRSG-113-02 and GRSG-113-37 justifying the alignment of the provisions in the UN Regulation with those in the latest version of ISO 11439:2013 (as proposed in ECE/TRANS/WP.29/GRSG/2017/31). The expert from OICA expressed his preference to adopt the proposal as a new series of amendments and suggested inserting transitional provisions (GRSG-113-21). GRSG agreed on the need to insert transitional provisions and to replace the dynamic references to international standards by static ones. Following the discussion, the expert from ISO presented GRSG-113-38 taking into account the comments received. GRSG considered the document in detail and adopted the proposal as reproduced in Annex IV (based on GRSG-113-38-Rev.1). The secretariat was requested to submit it to WP.29 and AC.1, as a new draft 03 series of amendments to UN Regulation No. 110, for consideration at their March 2018 sessions.

39. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/17 to improve the specifications for the installation and inspection of Compressed Natural Gas (CNG) cylinders or of Liquefied Natural Gas (LNG) tanks and their accessories. GRSG welcomed the proposal and noted that WP.29 and the Administrative Committee of the 1997 Agreement were expected to consider and adopt ECE/TRANS/WP.29/2017/134 on a new UN Rule on Periodical Technical Inspections of motor vehicles using CNG and/or LNG in their propulsion system. The proposal from Germany received a number of comments, especially on the need to align the recommendations for the periodical technical inspections of such vehicles with the specifications for the re-qualification of the CNG cylinders or LNG tanks. GRSG noted the comments received by the experts from NGV Global (GRSG-113-03) and OICA (GRSG-113-20).

Proposal to improve provisions for the visual inspection of CNG cylinders, LNG tanks, and their accessories. Germany has proposed (document GRSG-112-33) the prohibition of components or parts of protective housing which must be disassembled during inspection. Italy has proposed (document GRSG-112-28) that visual inspection of cylinders Include access inside any protective covers of the cylinders. Based upon field experience, OICA believes that corrosion damage between support straps, brackets, and pads and the cylinder can be readily identified during visual inspection. Such corrosion requires cylinder replacement. Therefore, OICA proposes clarifications to inspection procedures to address the German and Italian concerns.

40. The expert from Italy proposed to amend in Annex 3A of the Regulation the test requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life (ECE/TRANS/WP.29/GRSG/2017/29). The expert from the Netherlands raised his concern on the access by inspection centres to detailed provisions for the inspection of such cylinders. Thus, he underlined the need that cylinder manufacturers should make available cylinder inspection manuals. GRSG welcomed the offer by Germany to take the lead of a Task Force to review ECE/TRANS/WP.29/GRSG/2017/17 and ECE/TRANS/WP.29/GRSG/2017/29. It was agreed to also involve the International Motor Vehicle Inspection Committee (CITA) in the discussion and to resume consideration of this subject at its next GRSG session in April 2018.

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. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document, prepared by the Netherlands, taking into account the comments received.

Reference Number: GRSG-113-24
|
|
Proposal for further discussion concerning technical advances in the use of CNG accumulators as an intermediate technology for promoting high, stable pressure in CNG engine injection systems. The CNG accumulator is used to stabilize the gas pressure and to allow engine operation whenever the LNG supply system is not able to deliver fuel. This proposal would define requirements to enable the certification of these components.

Proposal for amendments to Regulation No. 110 - CNG compressor
|
|
Reference Number: GRSG-113-25
|
|
Proposal for discussion to enable the certification of CNG compressor components. Due to density and temperature constraints, LNG fuel systems require technologies to warm the LNG fuel to reach temperatures and pressures suitable for the engine. In some configurations, this involves the use of CNG compressors. Therefore, this proposal seeks to enable use of this technology through establishment of requirements to ensure safety.

42. The expert from the Netherlands introduced GRSG-113-26 proposing to correct and clarify the references to Annex 5Q in UN Regulation No. 110. GRSG welcomed the proposal and invited the expert from the Netherlands to prepare an official document for consideration at the next session of GRSG in April 2018.

Proposal to clarify the test procedure to be applied in assessing compliance with the requirement for “compatibility with heat exchange fluids of non-metallic parts” Annex 5Q is part of UN Regulation No. 110. In Annex 4D, the wording “Compatibility with heat exchange fluids” is used but there is no reference to the applicable tests. The proposal clarifies that the “LNG heat exchanger – vaporizer” falls within Annex 5Q. The proposal correspondingly clarifies the general overview Figure 1-2, with all tests from Annex 5, and Table 5.1 in Annex 5.

43. The expert from the NGV Global proposed to correct Table 6.4. on the cylinder design qualification tests (GRSG-113-06). GRSG noted general support on the proposal and agreed to take a final position on this subject at its next session. The secretariat was requested to circulate GRSG-113-06 with an official symbol.

Proposal for a corrigendum to Revision 3 of UN Regulation No. 110

Reference Number: GRSG-113-06

|
In the absence of complete harmonization with ISO 11439, this proposal recommends that Table 6.4 of UN R110 should be amended by the following for CNG-1 designs: - Delete A.17, A.25, and A.7 since they do not match the tests specified in paragraph 7.5 on Cylinder design qualification tests
- Add A.15 and A.6 since they do match the tests specified in paragraph 7.5 on Cylinder design qualification tests
- Add A.24 because paragraph 6.9 on Fire protection requires all PRDs on all cylinder types to comply with A.24.
