Abstract: In order to meet the matching performance testing requirement for different engine oil cooling systems, a performance test system for engine oil radiators with higher automation has been developed. It can measure and control many parameters of oil and cooling water, such as temperature, flow, pressure and so on, in real-time. It also can analyze and display the performance parameters of the radiator. Moreover, this system also has the function of data storage and query. In this article, the system design scheme, accurate ways for measuring and controlling the key parameters were introduced in detail. Experimental results show that, the control precision and test efficiency of this system are rather good, and it also can assist to accomplish the performance testing of other complete machines or components.
