The purpose of this proposal is to adjust the engine power-measurement calculation for supercharged and turbocharged engines fitted with a system that compensates for ambient conditions such as temperature and altitude. The proposed change would eliminate redundant correction factors that result in inaccurate results for these engine configurations.

Proposal from the GRPE secretariat to correct typographical and editorial errors in the current official text.

Editorial correction to the proposal to adapt the on-board diagnostics (OBD) requirements of UN R83 in line with technical progress.

Editorial corrections to the proposal to update the on-board diagnostics (OBD) requirements of Regulation No. 83 in line with technological progress.

This proposal aligns the transitional provisions of Revision 6 of UN Regulation 49 and thus in document GRPE/2014/3 with the General Guidelines for UN Regulations (WP.29/1044/Rev.1). This change requires changes to Table 1 of Annex 3 to cover diesel and dual-fuel engines bearing the letter B.

The proposal also would allow for methods other than monitoring the reagent tank level or reagent flow in order to monitor reagent consumption in Annex 11.

Consolidation of documents GRPE/2015/3 (proposal to adapt requirements to the current technology and to transpose the latest decisions of the European Union (EU) regarding on-board diagnosis (OBD) threshold limits) and GRPE-70-06 (concerning transition provisions and reagent consumption monitoring methods).

Session agenda updated to include document submissions through 14 January 2015.

Proposal for an informal expert group to exchange information and develop recommendations concerning vehicle interior air quality as it relates to emissions of volatile organic compounds or aldehydes from materials used in vehicle interior which are harmful to humans. The proposal envisions the development of test procedures to measure such emissions for incorporation as recommendations within the Consolidated Resolution on the Construction of Vehicles (RE3 under the 1958 Agreement), Special Resolution 1 (SR1 under the 1998 Agreement), or as a new Mutual Resolution (covering both agreements).

Recently EU-Directive 2013/60 has been introduced in which chapter 5 of EU Directive 97/24 is amended. One of the amendments concerns the introduction of reference fuels E5 (petrol) and B5 (diesel fuel). When stage C in 97/24-5 is being applied for, reference is made to GTR No. 2. In GTR No. 2, however, these reference fuels have not yet been incorporated. Document GRPE-69-02 proposed to incorporate these fuels into GTR No. 2; however, pursuant to comment received from several Contracting Parties, the Netherlands proposes to withdraw the document while retaining the option to revisit the issue in the future.

European Commission presentation reviewing the issues involved with transposing GTR 15 into EU emissions and fuel consumption regulations and into UN R83 and UN R101. The EC proposes that WP.29 should transpose GTR 15 into a new “WLTP UN Regulation” that would supersede UN R83 and UN R101.

Status of US EPA program to validate the HILS methodology and resolve error codes.

The purpose of this proposal is to amend the document GRPE/2015/2 in order to clarify the validity of 06 series of amendment, avoid discrepancies related to the date of entry into force of 07 series of amendment and better clarify the wording of transitional provisions and align them with the General Guidelines for UN Regulatory Procedures and Transitional Provisions in UN Regulations.

Progress report on work related to exhaust emission particulates and on non-exhaust (brake and tire wear) particle emissions.

Proposal to align the draft Amendment with the harmonized terminology and definitions developed by the informal group on Vehicle Propulsion System Definitions.

OICA proposal to emphasize a focus on building from existing industry measurement techniques and other standards as well as to clarify the subject of the group on vehicle “interior” rather than “indoor” air quality.

Supporting information concerning documents GRPE/2015/3, GRPE-70-06, and GRPE-70-07 (Proposal from the International Organization of Motor Vehicle Manufacturers (OICA) to adapt certain requirements to the current state of technology and to transpose the latest decisions of the European Union (EU) regarding on-board diagnosis (OBD) threshold limits).

Presentation of potential areas for the further development of the global regulation on light vehicle emissions, including test procedures regarding low ambient temperatures, high altitude testing, in service conformity, and durability of catalyst, DPF, and SCR systems as well as electrified vehicle batteries and motors.

Questionnaire presented to Contracting Parties to the 1998 Agreement to gather views on areas to be addressed in the next phase in the development of the global test procedures related to light vehicle emissions.

Outline the next steps of WLTP informal working group for the development of electrified vehicle regulations, as supported by the European Commission, and suggestion of possible areas for collaboration with the informal working group on Electric Vehicles and the Environment (EVE).

Presentation on Japanese efforts to develop a method for measuring the impact of air-conditioner use on motor vehicle fuel efficiency.
