OICA views concerning thermal propagation risks and the need for testing to evaluate such risks.

In 2011 a particle number (PN) limit was introduced in the European Union’s vehicle exhaust legislation for diesel passenger cars. The PN method requires measurement of solid particles (i.e. those that do not evaporate at 350 °C) with diameters above 23 nm. In 2013 the same approach was introduced for heavy duty engines and in 2014 for gasoline direct injection vehicles. This decision was based on a long evaluation that concluded that there is no significant sub-23 nm fraction for these technologies. This SAE paper (2015-24-2512) examines the suitability of this PN method for L-category vehicles (two- or three-wheel vehicles and quadri-cycles).

Ford Motor Co. presentation concerning primarily the generation of ultrafine particles from the tire–road interface and of particle resuspension from the road surface.

Proposal to include visual/audible inspections of batteries and pass/fail criteria throughout the electric vehicle safety test procedures in order to address risks associated with the release of flammable and toxic gases intended to relieve internal pressure and avoid battery ruptures or explosion.

At the 8th EVS GTR IWG meeting in Changchun, members of EVS Task Force 1 continued to discuss proposed requirements and test procedures (EVS-08-17) to address the safety performance of EVs during in-use in events of flooding and vehicle washing. As an action item, members were requested to provide comments on the overall proposal, specifically, water depth (10cm) and vehicle speed (20 km/h) for the drive test. The US believes that a 10 cm water depth test presents a reasonable and likely scenario for testing electric vehicle performance.

UN Regulations Nos. 49 and 83 include provisions for a “driver inducement system” that alerts drivers of low reagent levels (urea, etc.) critical to correct emissions control performance and eventually prevents vehicle operation if the reagent tank is empty. Under UN R49 (para. 5.2), rescue, police, and other emergency/special use vehicles are exempted from this requirement. This proposal would extend the same treatment under UN R83.

Summary of open issues, including items identified following the 12th WLTP informal group session, to be resolved towards finalizing the first phase development of the GTR on light vehicle emissions.

Draft informal document for eventual submission to the 72nd GRPE session (January 2016) containing final touches to the formal proposal (GRPE/2016/3) for the phase 1b amendments to the GTR on light vehicle emissions.

Consolidated proposal for the phase 1b amendments to GTR No. 15 including the changes presented in document WLTP-13-05 (marked up for easy reference).

Proposed Phase 2 organisation including structure for leading team and taskforces.

Project plan for the development of additional light-vehicle emissions test procedures for presentation to GRPE in January 2019. Phase 2 is expected to address test cycles (gear shift, normalization, and driving index), evaporative emissions, OBD, durability, and in-use compliance as well as supplemental tests for high altitude, severe cold, mobile air-conditioning, idling and crankcase emissions, and “eco-innovation”.

Proposal from Japan to clarify the specific objectives and intentions behind the list of supplemental test procedures developed for Phase 2 of GTR No. 15.

“Starter presentation” to launch discussions and work on evaporative emissions under Phase 2 of the GTR development.

Working draft regulation on uniform provisions concerning the approval of dual-fuel retrofit systems to be installed on heavy duty diesel engines and vehicles.

Research paper concerning the life-cycle CO2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) across the United States. The authors found large variations in the estimates across regions, charging schemes (for example, higher use of coal to generate power during overnight charging), and vehicle models (including differing relative results between models under different regional charging scenarios).
