OIL # 27: Number of tests: Progress report was presented by T. Fujiwara (WLTP-11-20e), incl. initial proposal for hybrid vehicles by Japan. Feedback on options for Dp values were given by EU and Korea. Japan proposed a compromise position with regional options for CO2. JRC recommended to set Dp2 to 50% of Dp1. India as well as Korea supported to find a harmonized solution. OICA stressed the induced additional test burden and will provide CO2 spread from a German round robin exercise. EU could support the proposed approach but will review the proposal in EU WLTP. Chair encouraged EU Com to consider a compromise which ensures a harmonized GTR solution; Japan could go with Dp1 and Dp2 as zero. EU will give feedback until end of June.
TF proposed Dp values for test results of EV concepts and gave examples of procedure on handling the test results. SG EV is asked to join the TF for clarification on handling of EV results. India required to consider re-declaration of rated power and max vehicle speed and asks for clarification in the GTR. IWG asked TF to work further on that open issues.
EU asks TF to review the CO2 family criteria in regard to robustness for criteria pollutants.
OIL # 29, 30, 41: Speed trace violations / Drive Trace Index: Progress report/proposal was given by N. Ichikawa (WLTP-11-21e / -22e) incl. evaluation of other criteria of driving indexes. Proposals for thresholds were discussed and will be worked on. US EPA was asked to join the task force. TF is requested to provide draft gtr text and involve SG Drafting as soon as possible. India asked for considering all class of vehicles and the required sampling frequency.
OIL# 31: Provisions for Coasting (WLTP Phase 2 item): TF led by T. Vogel asked CP’s for support in defining a coasting definitions for further work in WLTP phase 2.
