Proposal on a family definition for road load determination.

Definition of wind tunnel for road load determination (Open Issues #10 and #18).

Real-time tailpipe ammonia measurements from vehicles tested over the new Worldwide harmonized Light-duty vehicle Test Cycle (WLTC)

WLTP Phase 1b: Generic formula for hydrocarbon density

Initial material for deliberations on road load curve determination.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to adapt some requirements to the current state of technology and to transpose the latest decisions of the EU regarding OBD threshold limits.

Proposed text of the guide to worldwide environmental and related regulations concerning electric vehicles as developed by the informal working group on Electric Vehicles and the Environment.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order 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.

Proposal to enable Contracting Parties to continue to issue type approvals for agricultural tractor and non-road mobile machinery engines according to earlier versions of the Regulation provided such engines are destined for sale in countries that apply the earlier versions. In other words, a manufacturer would be able to obtain approvals in its home country based upon previous sets of requirements that may not be those applied within the home country (but are used in other markets).

Zip compressed file for the amendment and related materials to enable the use of a Hardware-in-the-loop simulation (HILS) method for the certification of heavy-duty hybrid vehicles under Global Technical Regulation No. 4.

Draft text of the proposed regulation on heavy-duty vehicle dual-fuel retrofit systems (version 7.0 as prepared by the AEGPL).

Draft guidelines for the task forces being set up under the Electric Vehicle Safety Informal Working Group to pursue specific elements (protection against water, low electric energy, electrolyte leakage, rechargeable energy system in-use test protocol, cell/module/system testing, state of charge and fire resistance) envisioned for the proposed new global technical regulation.

Directions to the US Department of Transportation headquarters in Washington, DC.

This document describes the calibration and validation procedures for the VPR. Calibration of the VPR is to be performed at the point of manufacture and validation is to be performed at least at 6 month intervals for all instruments without automatic temperature sensors or at least at 12 month intervals if automatic temperature sensors are present. The calibration procedure must be repeated if the system ‘fails’ its validation procedure or the particle number measurement system is modified in any way.

The scope of EU Euro VI standards for heavy-duty vehicles has been expanded compared with Euro V. In order to prevent inconsistencies that could affect the ability to offer all vehicles for export, this proposal would apply the expanded scope retrospectively to the 05 series of amendments to UN R49. This proposal was adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/6, not amended.

Progress reports from TUG (chassis dynamometer corrections) and TNO (coast down corrections) covering preliminary results (as of 27.03.2014).

Proposal to align the regulation with the full requirements for vehicles that meet “special social needs” under the regulatory framework of the European Union. In response to the extension of the scope of Euro VI legislation down to 2380 kg vehicles, this proposal would also add an exemption to take into account overlap between UN R83 and UN R101 with regard to light-duty vehicle CO₂ emissions and fuel/energy consumption. This proposal was adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/3, as amended by para. 25. of the session report and document GRPE/2014/7, not amended.

Proposal to align UN Regulation No. 101 with the latest changes in the regulatory framework of the European Union in relation to the specifications of new reference fuels E10 and B7. Adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/5, not amended.

Proposal to revise the definitions of REC devices and to introduce stricter limit values (reduction levels) for REC systems and transitional provisions for the sale of REC systems that meet the requirements of the REC Regulation in its original form. To assure coherence with the change in the definitions, the text also includes a revision of the test sequence for particulate reduction and the equivalence matrix for the Regulation No. 49 Standard series. The text was adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/4 as amended by GRPE-68-17-Rev.2.

Draft revision 01 (second issue) of the draft new regulation on uniform provisions concerning the approval of dual fuel retrofit systems to be installed on heavy duty diesel engines and vehicles submitted by ACEA. The previous version (Revision 00: first issue) was submitted by the AEGPL.
