Abstract According to the dynamic operation process of the electronic fuel injector (EFI), the coil current of the EFI can bitterly reflect its dynamic response time, which is the measurement mechanism. Then the test circuits of the opening and closing response time of the EFI were designed, and the measurement system was developed with the C8051F310 as the processor. And the measurement system is low cost, convenient and high precision. The results show that the measurement errors of the opening and closing response time of the EFI were 0.9% and 1.14%, and this meet to the testing requirements of some research on the EFI.
