Report of the working group developing emissions and fuel economy test procedures for heavy-duty hybrid vehicles to the 68th session of the Working Party on Pollution and Energy.

Report covering the reactivation of the WLTP (light vehicle emissions GTR) informal working group and its work on “Phase 1b” aimed at refining the original GTR currently pending adoption before the World Forum.

Recommendations by AECC, CLEPA, EUROMOT, and OICA for minimum quality attributes of market fuels (i.e. gasoline and diesel) to be introduced “in parallel, and at the same time, to complement the level of motor vehicle and non-road mobile machinery pollutant emission standards that a country or region may be considering to introduce”.

Revised recommendations by AECC, CLEPA, EUROMOT, and OICA, pursuant to discussions during the GRPE-68 session, for minimum quality attributes of market fuels (i.e. gasoline and diesel) to be introduced “in parallel, and at the same time, to complement the level of motor vehicle and non-road mobile machinery pollutant emission standards that a country or region may be considering to introduce”.

Updated proposal for the second phase amendments to the retrofit emission control devices regulation from the REC informal working group.

Further updated proposal for the second phase amendments to the retrofit emission control devices regulation from the REC informal working group.

Pursuant to GRPE 68th session discussions, further updated proposal for the second phase amendments to the retrofit emission control devices regulation from the REC informal working group.

Request for guidance from Germany on the possible further development of the regulation on replacement catalytic converters pursuant to the findings of a German study. The request particularly asks whether the regulation should require improved durability and emissions performance and whether a working group should be established to develop specific proposals. The document includes the findings on the emission performance of approved pollution control devices under the current UN R103.

Report to the GRPE on the project to standardize WP.29 terms used in reference to vehicle propulsion systems.

Review by the Particle Measurement Program expert group of research on airborne particles from non-exhaust sources, especially particulates from brake friction materials and tires. The PMP group is evaluating whether such non-exhaust particulates represent an appropriate and feasible concern for further consideration as a possible regulatory issue.

Review of main issues concerning the measurement of sub-23 nm particles in vehicle exhaust, including work on NRMM vehicles.

Progress report on activities concerning environmental issues related to electric vehicles.

Status report on the group’s current activities, including work on a new regulation covering heavy-duty dual-fuel retrofit systems.

Status report on the group’s activities to develop amendments to GTR No. 2 on motorcycle emissions and new global technical regulations concerning L-category vehicle propulsion systems. The group’s priority interests include targets include evaporative emissions and on-board diagnostics testing, followed by tests for tailpipe emissions after cold start. Other interests include tailpipe emissions test at (increased) idle / free acceleration; emission test of crankcase gases; durability testing of pollution control devices; and measurement of CO2 emissions, fuel consumption, electric energy consumption and electric range determination; procedures to measure power and torque for propulsion technologies fitted on L-category vehicles; and uniform measurement of maximum design vehicle speed and/or power for restricted L-category vehicles.

Text prepared by the European Commission to align the requirements of Regulation No. 83 with those of European Union Regulation (EC) Nos. 715/2007, 692/2008, 566/2011, 459/2012 and 630/2012. It updates the text of document GRPE/2013/11, including additional definitions on: vehicle power, engine and vehicle characteristics, information concerning the conduct of tests (namely for power and torque), the specifications of new reference fuels (E10 and B7), the type approval communication of test results for bi fuel vehicles, and clarifications on OBD threshold limits.

Text prepared by OICA to align the regulation with the full requirements for vehicles that meet “special social needs” under the regulatory framework of the European Union.

Proposal prepared by the REC expert group for the 01 series of amendments to the UN Regulation on uniform provisions concerning the approval of Retrofit Emission Control devices for heavy-duty vehicles. The text includes a revision in the definitions of the REC devices, 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.

Text prepared by the European Commission to align the requirements of 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.

As the Euro VI standards for heavy duty vehicles become mandatory throughout the European Union, manufacturers may adapt their certification processes to take account of the extended scope of Euro VI compared to Euro V. In order to prevent inconsistencies that could affect the ability to offer all vehicles for export, it is proposed to carry back this scope amendment retrospectively to the 05 series of amendments.

Since Euro VI will be fully implemented in the EU from 31 December 2013, this amendment has no effect on EU Approvals or equivalences.

When the scope of Euro VI legislation in the EU was extended downwards to 2,380 kg, the vehicles which are so approved were not exempted from light duty approvals. As the measurement of CO2 emissions and fuel/energy consumption is covered by UN Regulation No. 101, this proposal would add an exemption clause in UN Regulation No. 83 to take into account this overlap with light-duty vehicle requirements.

Proposal for a series of amendments to update the on-board diagnostics (OBD) requirements in line with technological progress, including changes in ISO standards.
