23. As mentioned under paragraph 22 above, the expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2012/25. Thus, GRSG agreed to resume consideration of this subject at its next session on the basis of a joint proposal by AEGPL, CLEPA and NGVA Europe.

24. The expert from the Netherlands reported on the outcome of the most recent expert meetings of the task force on Liquefied Natural Gas vehicles (LNG), held in Geneva on 1-2 October 2012 (GRSG-103-14). As the secretariat had not been in the position to prepare in due time the official document, he presented GRSG-103-11-Rev.1, proposing to insert into UN Regulation No. 110 new provisions for LNG vehicles. GRSG acknowledged the work done by the LNG task force and noted a number of comments. Following the discussion, the Chair invited all experts to send their written comments by the beginning of November 2012 to the LNG Secretary (jseisler@cleanfuelsconsulting.org). GRSG noted the intention of the LNG task force to present a revised proposal at the forthcoming session of the Working Party on Pollution and Energy (GRPE) in January 2013 and to consider it in detail at the next session of GRSG on the basis of an official document, taking into account the comments received.

35. On behalf of the task force on Liquefied Natural Gas vehicles (LNG), the expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2013/7 proposing to insert into UN Regulation No. 110 new provisions for vehicles using LNG in their propulsion systems. He also presented GRSG-104-34, GRSG-104-35, GRSG-104-36, GRSG-104-37 and GRSG-104-38 proposing further improvements to the text as agreed by the task force during its meeting on 15 April 2013, prior to the GRSG session. GRSG noted GRSG-104-32 justifying the need for such amendments as well as GRSG-104-33 listing a number of questions and answers on general LNG background issues.

36. GRSG acknowledged the work done by the LNG task force and considered ECE/TRANS/WP.29/GRSG/2013/7 in detail. GRSG adopted the document, as reproduced in GRSG-104-44, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 110, subject to a final review of GRSG-104-44 by the Working Party on Pollution and Energy (GRPE) at its forthcoming session in June 2013, particularly on environmental issues.

37. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 110 type approval provisions for electronic control units (ECUs). GRSG adopted the document, as amended, and agreed to reflect the adopted text in GRSG-104-44, mentioned above.

38. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11 proposing to introduce into UN Regulation No. 110 type approval provisions for fuel selection systems. GRSG noted a number of concerns and preferred to refer the proposal to the informal group on Gaseous Fuelled Vehicles (GFV) for detailed consideration at the forthcoming session in Brussels. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.

39. The expert from CLEPA also proposed to introduce type approval provisions for “valve control at the stop-start function” into UN Regulation No. 110 (ECE/TRANS/WP.29/GRSG/2013/12). The expert from OICA presented GRSG-104-19 improving the proposed text. GRSG agreed in principle on the both proposals, but preferred again to refer the proposal to GFV for detailed review. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
