2016/4/25 Japan Automobile Research Institute 11 Asian Round Robin Test WLTP-IWG April 2016 Prepared by JAPAN WLTP-14-11e

2016/4/25 Japan Automobile Research Institute 22 Purposes to check the understanding and application of the GTR15 (based on Phase 1a text) in different labs to evaluate the repeatability and reproducibility of the test procedure Toyota WISH 1.8L, 105kW, CVT Mahindra & Mahindra XUV L, 103kW, 6MT

2016/4/25 Japan Automobile Research Institute 33 Test schedule Gasoline vehicle (V1) : 8 labs(10 data sets), 30 tests(25 effective data) Diesel vehicle (V2) : 4 labs, 13 tests, ARAI will re-test at the end Need to coordinate the vehicle transportation between Asia and Europe

2016/4/25 Japan Automobile Research Institute 4 Test results - CO2, 4-phase  Gasoline vehicle (V1)  Diesel vehicle (V2) Big difference on V2 results. Warm-up procedure for RL setting on chassis dyno was different from GTR. (It was corrected to what the GTR described at the gasoline vehicle test.) *) Lab. C: Fuel type was different (E0 petrol) Error bar: MAX - MIN

2016/4/25 Japan Automobile Research Institute 5 Comparison with European RRT  Gasoline vehicle  Diesel vehicle Detailed data can be seen in Appendix *) Reference of EU RRT result: WLTP-13-06e and GRPE Asian RRT (Toyota WISH) EU RRT (BMW 116i) Asian RRT (Mahindra XUV500) EU RRT (Alfa Romeo Giulietta)

2016/4/25 Japan Automobile Research Institute 6 Test results – Charge balance, 4-phase  Gasoline vehicle (V1)  Diesel vehicle (V2) There was a big difference between Lab. D’s result and others (Test equipment has no problem. Mistake in data processing??)

2016/4/25 Japan Automobile Research Institute 77 Summary (Temporary) ItemDetailAction Lab. equipmentTemperature in the test cell and soak area One lab could not set at 23 deg. C during RR program because of other on going programs will be changed when WLTP is introduced Maximum speed of Cooling fan Lacking the speed of cooling fan at one labNeed to upgrade the cooling fan Width of Cooling fanWidth of cooling fan is shorter than that of GTR requirement at on lab Need to renewal or update/modification Length of Connecting tube length of connecting tube is longer than that of GTR requirement at one lab. Need to modification RCB measurement equipment One lab doesn’t have a RCB measurement system yet Need to be introduced the equipment Data recording system Two labs could not record the vehicle speed of 10Hz. Need to upgrade the data recording system Test procedureWarm up procedure for RL setting Unique method was applied to the RL setting at one lab Follow the GTR procedure RCB measurementHigher dispersion was observed on RCB balance at one lab Need more training Driving traceDriving trace indexVariation was observed in each indexFollow the trace as much as possible Variation was observed in CO 2 between labs. However, it will be reduced if the following actions are taken. New!
