Open issues list concerning the proposed global technical regulation on motorcycle crankcase and evaporative emissions from the sixth session of the expert group on motorcycle emissions and propulsion systems.

Presentation on the development of motorcycle emissions standards and motorcycle market in China and comment on motorcycle OBD regulation.

Presentation on scenarios for deployment of electrified vehicles in the United States and impact on power consumption and CO₂ emissions.

Presentation on the organization of work projects under the program to develop global technical regulations on electric vehicle safety (Electric Vehicle Safety informal working group).

Suggestion by the European Commission to develop several global technical regulations concerning specific environmental aspects of electrified vehicles falling outside the scope of the WLTP (Worldwide Light vehicle Test Procedure for emissions and fuel efficiency) test cycle. These new GTR would complement the WLTP work by addressing adjacent issues such as battery durability or charging performance. The idea is to allow for these complementary rules to be referenced within the WLTP or other GTR but also to enable their use as stand-alone rules regardless of whether a nation applies WLTP.

Fourth draft of the electric vehicle reference guide on environmental regulations worldwide.

Revised Japanese presentation of proposals for the scope of the global technical regulation on motorcycle crankcase and evaporative emissions and proposals for changes to the draft test specifications.

Revised Japanese government position and recommendations for the proposed global technical regulation for motorcycle on-board diagnostic systems.

The informal group developing safety requirements specific to electrified vehicles has decided to break its work down into specific areas for development by individual task forces. This document, provided as a courtesy to the sister informal group focused on environmental aspects of electrified vehicles, outline the rules and procedures for these safety-requirement task forces.

Revised presentation on a research project intended primarily to evaluate regenerative braking energy and CO2 emission differences between a 2-wheel dynamometer, a 4-wheel dynamometer and empirically determined rear-axle braking forces applied the same test conditions on a 2-wheel dynamometer. The expectation is that the two-wheel dyno tests will produce the highest regenerative braking energy and lowest CO2 emissions since it places 100% of the braking load on the rear axle.

Revised presentation on the results of a cooperative research project between China and the EU on a system to evaluate the aggregate energy consumption (including upstream and downstream elements) of electrified vehicles.

Report from the special session focused on retrofit heavy-duty dual fuel systems.

Voting form for the adoption vote on light vehicle emissions and tires.

Note from the WP.29 secretariat to convey concerns received from the Netherlands and Romania on the planned vote to amend UN Rules Nos. 1 and 2 on vehicle inspections.

Proposal to extend the mandate of the informal working group on heavy-duty hybrids to allow for the adaptation of the hybrid provisions developed for GTR No. 4 (WHDC heavy-duty emissions test cycle) to GTR No. 11 (Non-road vehicle emissions).

Presentation on Korean steps to address concerns over emissions of volatile organic compounds including formaldehyde, toluene, ethylbenzene, styrene, benzene, and xylene emanating from materials used in vehicle interior components such as dashboards, carpeting, and seats.

Presentation on the use of “sailing” technologies to reduce CO₂ emissions and raising a question over the ability of the WLTP test cycle to account for the effect of sailing on vehicle emissions and fuel consumption performance. Sailing involves the decoupling of the engine from the drive shaft, enabling hybrid vehicles to cruise (or “sail”) on battery power alone until such time as the engine needs to be restarted to generate electricity and/or resume the torque functions.

Table of items for resolution in phase 1b in the development of the light vehicle emissions and fuel consumption global technical regulation.

Letter raising concerns regarding misinterpretation of the definition of a hybrid electric vehicle and resultant misapplication of approval requirements.
