Outline
Combing the existing engine product development test standards systematically, bechmarking the advanced test standards and test methods, analyzing multi-dimensional user scenario from the user driving purposes, road topology, temperature, humidity, user driving characteristics,then establish the engine test verification system facing the user complex use environment and working condition,all of the above is for improving the quality of engine products. Engine product development tests cover all user working conditions, including extreme working condition test, limit size test, extreme environment test, enhanced acceleration test, inspection compliance test, and user simulation test. For the special characteristics of products, development tests including the parts level, the system level, the machine level and the vehicle level are used to achieve the coverage of user scenarios of more than 95%, and ensure the high quality requirements of high reliability and low failure rate of the engine.
