Through the analysis of the flow characteristics of the high-speed solenoid valve, the conclusions that the PWM signal duty ratio is the main factor affecting the solenoid valve flow is obtained, a new available any PWM pulse signal and control circuit are proposed. Further, circuit schematic is simulated by means of SIMULINK tools in MATLAB environment and Verify its stability. A time-sharing drive circuit is design based on the PWM drive mode. The driver circuit have function which is high-current open, small current maintain. Open current and maintain current of Solenoid valve can be adjusted through this circuit. Therefore, the circuit can adapt to different parameters of the solenoid valve. A wide range of applications.

In order to develop actuation circuit for high pressure common rail injector solenoid valve, the high and low voltage time-sharing actuation control method based on current feedback was researched. A finite state machine tool called stateflow was used to establish the actuation model of solenoid, and the intelligent actuation control circuit was developed according to the model and MCU. The driving current can be adjusted automatically according to “Peak-High-Low” three-stage current, and the circuit can troubleshoot the state of solenoid. Driving Experiments on solenoid and injector were carried out and the results show the good performance of the intelligent actuation control circuit.
