Progress report on wind tunnel method, on-board anemometry and wind speed, torque meter method, default road load parameters, and road load family concept.

Presentation in support of Japan positions on the draft global technical regulation on crankcase and evaporative emissions from motorcycles and similar vehicles.

Proposal to amend the EC-prepared text for the stage I “requirements for two- or three-wheeled light motor vehicles with regard to on-board diagnostics”.

Proposal to add a generic formula for the density of total hydrocarbons to GTR No. 15 as part of phase 1b of its development.

Japanese proposals concern generic formulas for hydrocarbon density coefficients under WLTP.

Revisions to the proposal from OICA to update the on-board diagnostics (OBD) requirements in line with technological progress. This document includes amendments to the 06 and 07 series of amendments, (superseding documents GRPE/2014/8 and GRPE/2014/9 from the January 2014 GRPE session).

Proposed amendments to the OICA text proposed in order to adapt certain requirements to the current state of technology and to transpose the latest decisions of the EU regarding OBD threshold limits.

Document GRPE/2014/11 was prepared by the GRPE informal working group on heavy duty hybrids (HDH) to add the test procedure on heavy-duty hybrids to GTR No. 4.

This informal document revises and supplements GRPE/2014/11 in order to align GTR No. 4 and GTR No. 11 (NRMM) in accordance with the latest work of the HDH group. The renumbering of equations, tables and figures, the corresponding references, and the symbols list in paragraph 3.2 has not been completed in this document. This will be done during the final editing of GRPE/2014/11.

Summary of Japanese evaporative emissions test requirements, especially with regard to the correlation between evaporative limit values ​​and test fuels.

Presentation on Japanese requirements, especially with regard to malfunction indication, and proposal for incorporation within the proposed GTR on L-category vehicle on-board diagnostic systems.

Proposal for amendments to the EC-prepared text for the stage I “requirements for two- or three-wheeled light motor vehicles with regard to on-board diagnostics” (document EPPR-07-14).

Draft as of discussions through 23 May 2014.
