Position of Japan concerning the further development of the International Whole Vehicle Type Approval system, including work on UN Regulations 34, 46, and 125 and possible support for GTR 6 (UN R43), WLTP GTR and UN R51.

Presentation on the European Commission’s intentions for reducing CO2 emissions from heavy-duty vehicles.

Presentation from the International Council on Clean Technology reviewing various test methods in use for heavy-duty hybrids and evaluating opportunities for harmonization.

This document proposes to add the use of poly-alpha-olefin filters and to correct an error in the particle number measurement diagram in UN Regulation 49.

Presentation on US EPA hybrid-engine powerpack testing, future challenges, and comparison with GTR program.

Review of the current status of work and forward plans.

Presentation of a proposal for a revised ‘Worldwide heavy-duty hybrid test cycle’.

The Vienna and Graz Technical Universities have conducted research and offered recommendations for the heavy-duty hybrid emissions regulation. Japan comments on the TU-Wien and TU-Graz proposals.

TU-Wien presentation on its work with IFA on the assessment of HILS methodology and suggestions for the GTR validation test program.

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

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

Progress report of the working group developing the emissions and CO2 test procedure for heavy-duty hybrid vehicles.

Progress report and overview of the effort to develop a heavy-duty hybrid vehicle emissions test procedure based on hardware-in-the-loop simulations.

Presentation on testing of heavy-duty hybrid vehicles on a chassis dynamometer.

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.
