Comments and recommendations concerning the ‘extended HILS’ approach and application of the current worldwide heavy-duty vehicle emissions test cycle to hybrid vehicles.

Agenda for the ninth session of the informal group working on the test procedures for the worldwide light vehicle emissions test procedure.

Submission from the European Commission and OICA to amend the provisions of UN GTR No. 5 to clarify concerns identified during the preparation of legislation implementing the Euro VI emission levels (i.e. Regulation (EC) 595/2009), including a revision of the disablement conditions proposed in 2011.

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.

Paper intended to explore the inclusion of vehicle families in the WLTP GTR. In principle, global technical regulations (GTR) are restricted to technical issues such as test cycles and procedures and do not include definitions of families.

Proposal to align the requirements of the Regulation with those of European Union Regulation (EC) No 595/2009 and (EU) No 582/2011 (Euro VI ), including adding the use of poly-alpha-olefin filters and correcting an error in the particle number measurement diagram in UN R49.

Text adopted by the Working Party on Pollution and Energy (GRPE) at its sixty-third session to introduce amendments to Annex 9 of Regulation No. 101 regarding the procedure for determination of the electric range of hybrid electric vehicles taking into account the use of the fuel consuming engine.

Working draft of the proposed new “Regulation on uniform provisions concerning the
approval of Retrofit Emission Control Devices (REC) for heavy duty vehicles, agricultural and forestry tractors and non-road mobile machinery (NRMM) equipped with
Compression Ignition engines”.

Working draft for an eventual amendment to the retrofit emissions control devices regulation under development that would address particle measurement provisions.

Project schedule as of 10 April 2012 for development of the new regulation on retrofit emission control devices.

Proposals from the CECE for revisions to the draft text of the retrofit emissions control devices regulation concerning the articles on operating behavior and safety hazard, noise emissions, and installation of the devices.

OICA and Euromot response to the informal group on REC request to submit a proposal on NOx control measures based on the Euro VI and Nonroad Stage IV NOx control provisions.
