Electronically controlled EGR valve is an important part in the technology of exhaust gas recirculation, which includes the type of stepper motor, electromagnetic and DC motor. However, the research on electronic controlled EGR valve test system is not enough. So a comprehensive performance test system is developed. The system is composed of drive unit, control unit and test unit. Electronically controlled EGR valve drive is the drive core of the drive unit. The control unit is the core of the control unit, and the test unit is composed of the test modules of each index. Through the technical index test process design, system has realized the EGR valve flow characteristic, the internal leakage performance, the response time and the valve position sensor performance automatic test. Experimental results show that the system is stable and reliable, the parameters of the machine capability index Cmk are more than 1.67, accords with the technical requirements. The system provides a test plan for the comprehensive performance of the EGR valve, and successfully applied to the production and testing workshop of a company's electronic control EGR valve.
