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.

Presentation on REBRAKE, the European Commission-supported project to better understand brake-wear emissions and their impact on air quality.

Authorization prepared to enable the amendment of GTR No. 15 and to prolong the mandate of the WLTP informal working group as adopted by the Administrative Committee of the 1998 Agreement at its March 2014 session.

ACEA proposal for defining a hybrid key function (torque split for parallel hybrids and energy management for serial hybrids) in the configuration of HILS software in the testing heavy-duty hybrid vehicles. ACEA also proposes to exclude “micro” hybrid systems (i.e., 48-v based systems) used to supplement the internal combustion engine as a means to reduce CO₂ emissions and improve fuel efficiency. The exclusion criteria would be based upon the ratio of positive electrical power to total system power (to be defined).

Review of findings from the review of literature on particle emissions from non-exhaust sources covering tires and brake materials.

The HILS method currently used in Japan does use a cold-start test in hybrid testing; however, GTR No. 4 will use a cold-start test. This presentation discusses Japan’s proposal for a “predicted temperature method” that inputs the temperature profile of each component in advance.

Review of Korean results using the heavy-duty hybrid vehicle mode on a chassis dynamometer per the proposed amendment to enable hybrid vehicle testing under GTR No.4

Discussion presentation from Japan towards harmonizing the provisions for testing hybrid vehicles in the kokujikan and the proposed GTR to avoid divergent interpretations.

Discussion presentation on issues potentially impacting the measurement of PN during regeneration of gasoline particulate filters and diesel particulate filters on light-duty vehicles.

Presentation on Swedish and Scandinavian research into sources and impact of non-exhaust airborne particles, including from wear on roads, tires, brakes, and similar sources.

Summary of the PN calibration project under the European Metrology Research Programme’s project on “emerging requirements for measuring pollutants from automotive exhaust emissions” (EMRP ENV-02).

Draft copy for PMP informal group comment of the JRC Science and Policy Report.

Proposal as adopted by the GRPE at its 68th session based upon an original proposal (subsequently amended) 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.
