Working draft for a series of amendments that would align UN R83 with the Euro 6 approval requirements based on the amending Regulation (EC) No 459/2012 and Regulation (EC) No 630/2012. Proposal to be revised and transformed into a formal submission for the June 2013 GRPE session.

Report of the 22nd informal group on gaseous-fueled vehicles meeting.

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.

Proposal prepared by the WP.29 secretariat to correct a number of errors identified during the work to develop the 06 Series of Amendments for Regulation
No. 49 and currently affecting the 06 series of amendments to the Regulation No. 83.

GRPE-adopted proposal based on a submission from the International Organization of Motor Vehicle Manufacturers to incorporate the content of Regulation (EU) 566/2011 into the 06 series of amendments to UN Regulation No. 83.

GRPE-adopted proposal 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.

Presentation on the status of GFV activities, including for heavy-duty dual-fuel vehicles, bi-fuel gas vehicles, liquefied natural gas (LNG) vehicles, and support to the European Commission concerning THC/CH4 (methane).

Submission prepared by the Chair of the informal group on Gaseous Fuelled Vehicles (GFV) to correct measurement errors contained in documents GRPE/2012/6 (concerning UN R83) and GRPE/2012/7 (concerning UN R115) when weighing method and G20/G25 reference fuels are used.

Supplements 1 and 2 to the 06 series of amendments (Revision 4) to UN Regulation No. 83 include provisions to amend Annex 4; however Annex 4 does not exist, having been superseded by Annex 4a. The UNECE Secretariat proposes to delete the references to Annex 4 in the two supplements.

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.

The proposed amendments are aimed at redefining the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode. This submission follows the review by CLEPA members of the draft proposal (GRPE/2012/6).

Revised submission by the Chair of the informal group on Gaseous Fuelled Vehicles (GFV) 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. This document replaces GRPE/2012/6.

Revised submission from the International Organization of Motor Vehicle Manufacturers proposing to incorporate the content of Regulation (EU) 566/2011 into the 06 series of amendments to UN Regulation No. 83, succeeding informal document GRPE-63-16 and replacing GRPE/2012/11.

and its Heavy Duty Dual-Fuel Task Force.

Report from the January 17, 2012 session of the Gaseous-Fuelled Vehicles Informal Group.

Draft of the proposed amendments are aimed at redefining the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode. This proposal was submitted to the Working Party on Pollution and Energy as document GRPE-63-05.

This is a revised version of the proposal by the Gaseous Fueled Vehicles (GFV) informal group to redefine the class of bi-fuel vehicles under UN R83 in order to permit the simultaneous use of gas and petrol while in gas mode.

This proposal was prepared by the experts from the International Organization of Motor Vehicle Manufacturers (OICA) in order to incorporate the content of Regulation (EU) 566/2011 into UN Regulation No. 83.06.

The proposed amendments redefine the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode.
