Progress report of the LNG Task Force created to develop technical specifications for LNG (Liquefied Natural Gas) cryogenic components to be installed on-board road vehicles.

Documents GRPE/2012/6 and 7 introduce the calculation of NG/biomethane energy ratio during a type I cycle by weighing the NG/biomethane mass consumed. The formulas are affected by an error when G25 reference fuel is used. This proposal precribes a modification to the previous formulas.

Copy of the GRPE submission prepared by the GFV Chair of the informal group to correct a measurement error contained in documents GRPE/2012/6 (concerning UN R83) and GRPE/2012/7 (concerning UN R115) when weighing method and G25 reference fuel are used.

Working draft of the document consolidating working document GRPE/2012/13/Rev.1 with the pending informal documents GRPE-64-xx1 (completing the working document) and GRPE-64-xx2 (correcting the working document).

Revised version of document GRPE-62-17 prepared by the chair of the GFV informal group in order to extend the scope of Regulation No. 85 to include heavy-duty dual-fuel (diesel-gas) engines.

Document GRPE/2012/13/Rev.1. contains all the major amendments to Regulation No. 49 that are considered necessary to type approve heavy-Duty dual-fuel engines and vehicles, except appendixes 3, 4, 5 and 6 of Annex 15. This document corrects typographic errors and cross-references in that proposal.

Document GRPE/2012/13/Rev.1. contains amendments to Regulation No. 49 considered necessary to type-approve heavy-duty dual-fuel engines and vehicles, except for appendixes 3, 4, 5 and 6 of Annex 15. This document provides the missing appendices and offers editorial corrections to UN R49.

AEGPL comments on the proposed amendments to UN R67 and UN R110 with regard to the gas ECU type-approval and start & stop systems.

Documents GRPE-63-05/Rev.1 and GRPE/2012/6/Rev.1 propose to redefine the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode in UN Regulation No. 83. CLEPA proposes an alternative method to the weighing procedure of the fuel consumption test procedure.
