54. AEGPL updated the GFV on amendments dealing with safety that were proposed to the GRSG at their April 2011 meeting.( ECE/TRANS/WP.29/GRSG/2011/14 from the Netherlands and informal paper GRSG-100-02-Rev.1 from Italy that were approved.) But there also were some newly crafted definitions for bi-fuel vehicles that now are not in accordance with existing regulations. (LPG running mode and bi-fuel vehicle: See GFV-13-06). (ECE/TRANS/WP.29/GRSG/2011/15 amending paragraphs 17.11.5 and 17.11.6. related to diesel dual-fuel operation.) The approved amendments are now to be presented for agreement at WP29. Two options: 1) the amendment to WP29 can go forward; or 2) WP29 could be asked to forego approval of the definitions and await the results of any comparison of definitions as proposed by today’s GFV.
55. Mr. Duvielguerbigny summarizes the proposals made from GFV-13-06 reminding the group that Regulation 67 is specific to LPG only.
56. Mr. Rijnders is concerned that this new definition (bi-fuel) becomes confusing since existing definitions have applied to gaseous fuels and not just LPG. So we must now ask WP29 to either remove these definitions or adopt them and amend them in future.
57. Mr. Piccolo: The definition 2.21 in R.67 as adopted is in conflict with existing regulatory definitions. He suggests to eliminate provision 17.11.6. This is an emission-related provision (but not omit 17.11.5 which is about the switchover time from petrol to LPG).
58. Mr. Rijnders believes we are not ready for the upcoming GRPE to make a proposal. It is possible that we could make a formal amendment in September for the November WP29.
59. Mr. Hubert (UNECE GRPE Secretariat) suggests it is best to have a proposal to GRPE for discussion this week. Alternatively, a new proposal could be made again to the October GRSG meeting and then forward this to GRPE their consideration in January 2012.
60. Resolution: Mr. Rijnders suggests that the issue be moved back to the GRSG, taking suggested proposal from the GFV to the GRSG to reconsider for submittal to WP29 in November as a corrigendum to the previous amendments to R.110 from AEGPL/Italy.
