This proposal aims at harmonizing the text of UN Regulation No. 83 and UN Regulation No. 101. Furthermore, one error was found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and one wrong cross reference in the 01 series of amendments to UN Regulation No. 101.
1. Harmonization of UN Regulation No. 83 (Annex 4a, Appendix 7b, paragraph 1.) and UN Regulation No. 101 (Annex 7, Appendix 2, paragraph 1.); in Annex 7, Appendix 2, paragraph 1. Vehicles in general are not approved according to UN GTR No. 15, therefore the text phrase of UN R83 is recommended.
2. Correction of wrong reference to Annex 4 instead of Annex 7 of UN GTR No.15; in Annex 7, Appendix 2, paragraph 2.1.(b).
3. When copying the methodology from EU regulation, a ‘.’ was wrongly introduced instead of a ‘-‘ in the formula.

Proposal to amend Annex 7 – Appendix 2 paragraph 1., to provide the road load power calculation method that may be used

Proposes a shortened Test Procedure NEDC for PEV and alternative for conformity of procedure.

The presentation supports the proposal for a Shortened Test Procedure NEDC for PEV acc. to WLTP (including adding PEV COP procedure alternative).

This explanatory note by IWG PMP, updates on the proposals for solid particle number (SPN) measurements for the type approval of heavy-duty engines. The explanatory note addresses (i) the changes to the current SPN23 methodology, (ii) the proposed changes for the second alternative option to extend the particle size detection range to 10 nm particles, (iii) the proposed changes to allow direct SPN sampling with fixed dilution ratio.

This proposal from IWG PMP is based on the PN measurement procedure laid down in UN R49 but should be considered exclusively a technical working document. The purpose of this document is only to discuss within the PMP group the changes/additions needed to modify the PN cut-off size from 23 to approximately 10 nm and to include raw exhaust sampling
