Presentation Transcript

  1. WLTP DTP – Lab Process ICE • Development of Draft proposal following the approach agreed at DTP-02 (see WLTP-DTP-01-10 (OICA)):1) Identification of relevant contents in regional Regulations, basis: Working packets according to the WLTP DTP roadmap (WLTP-DTP-01-03) & Lab process overview send by Mike yesterday2) Comparison of contents 3) Equivalent  c&p, sign.differences  decision proposal to DTP • 4) possible modifications/improvements of harmonised requirements (improve reproducibility, narrow tolerances/flexibilities, …) in order to improve the measurement results with regard to the political aim  more adequate reflection of the real CO2 emissions behaviour of cars

  2. WLTP DTP – Lab Process ICE gaseous constituents reference fuel PN/PM Intersection within the 5 subgroups units terminology emission constituents Lab Process ICE Calculation formulae Lab Process HEV/ PHEV /EV/ FCV fuel consumption Testing liquid fuel Vehicle pre-conditioning Testing Gaseous fuel Vehicle pre-conditioning Testing Gaseous fuel Test Procedure Testing liquid fuel Test Procedure Inertia weight class

  3. WLTP DTP – Lab Process ICE • complex intersections permanent exchange with other subgroups is necessary After workshops and phone/web-conferences a short status report should be send to DTP and Subgroup Leaders (incl. state of progress and issues need to be discussed within DTP) Questions: • What is the common understanding of the gtr structure? • What are the detailed subject matters of the roadmap tasks?

  4. WLTP DTP – Lab Process ICE • Next Steps • Face-to-face workshop in July Compare US/EU/Japan regulation and start with copy/paste(gtr structure will be very helpful) • reg web- / telephone conference(Infrastructure for the webconference can be provided by Audi for Lab Process ICE subgroup) • (Face-to-face) workshop in Septin preparation of DTP meeting in Oct
