Draft new Regulation on uniform provisions concerning the approval of specific LPG (liquefied petroleum gases) or NG (compressed natural gas/bio-methane/liquefied natural gas) dual fuel retrofit systems and dual fuel retrofitted engines to be installed in heavy duty applications

Presentation on defining the terms “retrofit” and “conversion” in the context of equipping heavy duty vehicles with dual-fuel systems.

Report of the special session of the Working Party on Pollution and Energy to consider the initial version of the light vehicle emissions GTR for submission to WP.29 for adoption.

Proposal for a series of amendments to update the on-board diagnostics (OBD) requirements in line with technological progress, including changes in ISO standards.

When the scope of Euro VI legislation in the EU was extended downwards to 2,380 kg, the vehicles which are so approved were not exempted from light duty approvals. As the measurement of CO2 emissions and fuel/energy consumption is covered by UN Regulation No. 101, this proposal would add an exemption clause in UN Regulation No. 83 to take into account this overlap with light-duty vehicle requirements.

Initial working draft for a regulation to provide a framework for approvals of engine conversions (such as in retrofitting an engine for dual-fuel use).

The objective of the 8th EVE meeting will be to discuss the second draft of the EVE Reference Guide, which will also be submitted as an informal document for the 68th GRPE Session. This will include discussion of the Guide recommendations and future work for the EVE informal working group, including potential mandate extension and coordination with the WLTP informal working group.

(Please note that there were web conference meetings that appear to have confused the meeting numbering. According to the minutes of the 15th HDH informal group session, this meeting in Brussels would be the 8th rather than the 7th session of the drafting group.)

“Requirements for two- and three-wheeled light motor vehicles with regard to tailpipe emissions after cold start, tailpipe emissions at idle and free acceleration, [durability of pollution control devices] and energy efficiency.”

Proposal for clarifications to the European Commission proposal (document GRPE/2104/2) to align the requirements of Regulation No. 83 with those of European Union Regulation (EC) Nos. 715/2007, 692/2008, 566/2011, 459/2012 and 630/2012.

Proposal to enable continued type approval of engines meeting earlier versions of UN R96 provided that the engines in question are intended for markets applying such levels earlier of regulatory stringency.
