Proposal from the research institutions involved in assessing and adapting hardware-in-the-loop simulation (HILS) methodologies to the evaluation of heavy-duty hybrids for the anticipated second phase work to produce a HILS tool for use in GTR 4 hybrid vehicle provisions.

Gaseous-fueled vehicles informal group review of the proposals developed by the Heavy-Duty Dual-Fuel Task Force to introduce related provisions into UN Regulations Nos. 49 and 85.

Corrections to the document GRPE/2012/13/Rev.1 that proposes to introduce complementary specifications to the 06 series of amendments of UN R49 towards type-approving heavy-duty dual-fuel vehicles.

Document GRPE/2012/13/Rev.1 proposes to introduce complementary specifications to the 06 series of amendments of UN R49 towards the type-approval of heavy-duty dual-fuel vehicles.

Consolidated proposal for an amendment to Regulation No. 49 towards the type-approval of heavy-duty dual-fuel vehicles, incorporating:
- Working document GRPE/2012/13/Rev.1.
- Informal document GRPE-64-18 completing the working document
- Informal document GRPE-64-17 correcting the working document

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(Revision 4) to UN Regulation No. 83 include provisions to amend Annex 4; however Annex 4 does not exist, having been superseded by Annex 4a.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.

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.

This document is a revised version of informal document GRPE-62-17 intended to introduce provisions for heavy-duty dual-fuel vehicles into UN Regulation No. 85 in accordance with those proposed in the GFV proposal to amend Regulation R49.
