The performance target setting of passenger car engine cooling system is mainly based on the vehicle thermal balance test condition, at present, the formulation of vehicle thermal balance test conditions is based on the environmental conditions and actual road information of vehicle sales area, engine cooling system developed according to heat balance test conditions, only to ensure that the vehicle in the actual use of the process will not appear engine overheating. Modern vehicle in power, economy, emission, air conditioning comfor, off-road and reliability and other aspects put forward higher requirements, these performances are closely related to the working temperature of the engine and the working state of the accessories of the cooling system, therefore, the engine cooling system performance target setting needs to consider more dimensions. In this paper, the performance data of engine cooling system of more than 60 vehicles in recent 10 years are analyzed, show the development trend of cooling system performance, obtain engine cooling system temperature test data in vehicle performance development test, through the analysis of the test data, the real demand of engine cooling system performance under the condition of the vehicle is judged comprehensively, combined with the big data from the test, some suggestions are put forward from the maximum capacity of engine cooling system, temperature rise rate and temperature control.
