20. The expert from EC introduced GRPE-61-02 proposing a new series of amendments to Regulation No. 96. He explained that this proposal aimed at aligning the text of the Regulation with stages IIIB and IV of the corresponding EU directive and including the harmonized test procedure as defined in gtr No. 11. He highlighted the main modifications (GRPE-61-05). GRPE welcomed the proposal and agreed to consider it in detail at its next session in June 2011 on the basis of an official document to be submitted by the expert from EC.

21. Referring to GRPE-61-08, the expert from Italy suggested inserting into Regulation No. 96 additional transitional provisions for engines of some category T vehicles (narrow axle tractors). He volunteered to take the lead on this issue. GRPE welcomed this initiative and agreed to resume consideration of this subject at its next session in June 2011 on the basis of a concrete proposal.

48. Following the request of a number of experts, the secretariat explained the difficult situation within the Transport Division about publishing the legal text of new amendments to existing Regulations. He informed GRPE about the overall delay in the publication procedure and about the current status especially of the 06 series of amendments to Regulation No. 83 which had been adopted by the World Forum in March 2010 and already entered into force in December 2010. GRPE urged the secretariat to undertake all possible measures to anticipate any delay in the publishing procedure and invited the secretariat to make publicly available, as soon as possible, the legal text of the new series of amendments starting with the english version.

49. The expert from Japan introduced GRPE-61-07 outlining the intention of his Government to focus in future, on the further reduction of limit values for exhaust gas emissions from heavy duty vehicles.

47. Following WP.29’s request at its March 2010 session (ECE/TRANS/WP.29/1083, para. 27), GRPE considered the guidelines on establishing requirements for high-priority signals (GRPE-61-12). GRPE noted no reservations on this subject.

29. The Chair of the informal group on Gaseous-Fuelled Vehicles (GFV) underlined the urgent need to update the provisions of Regulation No. 115 (GRPE-61-15) with the Euro 5 emission requirements recently inserted into Regulation No. 83. GRPE adopted GRPE-61-15, as reproduced in Annex III to this report, and requested the secretariat to submit it to WP.29 and AC.1, for consideration at their sessions in June 2011, as Corrigendum 1 to Supplement 4 to Regulation No. 115.

30. The Chair of the informal group on GFV reported on the work progress made by the group at its recent meetings, held in Brussels on 8 November 2010 and in Geneva on 11 January 2011. He raised his concerns about bi-fuel vehicles with petrol direct injection (PDI) engines when the injectors need to inject a considerable amount of petrol even if the gas mode is selected, due to prevent overheating. He announced the intention of the informal group to prepare a concrete proposal on how to go forward.

31. The expert from OICA chairing the task force on heavy duty dual fuel (HDDF) gave a brief status report (GRPE-61-25) on the time-plan and the road map for adapting the relevant Regulations to the new Euro VI emission requirements. He proposed a way to address methane (CH4) and total hydrocarbon (THC) for HDDF vehicles equipped with a Type 2 engine. He also proposed a way to address HDDF engines fuelled with liquid natural gas (LNG). GRPE supported the time-plan and the roadmap and gave its consent to go forward with the proposed approach to address the emissions of HDDF engines.

32. GRPE agreed that the GFV group should also meet prior to the next session of GRPE in June 2011.

33. The expert from OICA recalled the purpose of ECE/TRANS/WP.29/GRPE/2009/8 proposing to clarify and update Regulation No. 83 on the specifications for the Flame Ionisation Detector (FID) hydrocarbon analyser. The experts from the Netherlands and Poland reconfirmed their concerns. The Chair recommended removing ECE/TRANS/WP.29/GRPE/2009/8 from the agenda of GRPE. He invited the expert from OICA to prepare jointly with the experts from EC, the Netherlands and Poland a revised proposal and to submit it to the informal group on WLTP for a detailed consideration.

34. The expert from the Netherlands proposed inserting into Regulation No. 83, new specifications for the proportional speed fan which might be used during the testing of vehicles on the chassis dynamometer. For this purpose, he introduced GRPE-61-19 clarifying ECE/TRANS/WP.29/GRPE/2011/6 and complementing it with transitional provisions. He withdrew ECE/TRANS/WP.29/GRPE/2011/5. GRPE adopted the proposal ECE/TRANS/WP.29/GRPE/2011/6, as reproduced in Annex IV to this report. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1, for consideration at their June 2011 sessions, as Supplement 2 to the 06 series of amendments to Regulation No. 83.
