In order to shorten hardware system development cycles and reduce development costs, a precise circuit model for the driving module of solenoid valve for common rail injection system was created. The impact of different driving voltages on the response time of actuators was analyzed based on the simulation results, and the circuit for shortening the close delay was realized. Based on a comprehensive analysis of the simulation results on the condition of different parameters, two driving voltage sources with 110 V and 24 V were adopted in different driving stages, hold current was feedback controlled by hardware pulse width modulation (PWM) signal, and fault detecting and diagnosing circuits were designed. The experimental results show that the open delay and close delay of the injector are shortened; the boost voltage is stable during the injection process; and the reliability of the design approach for common rail injection system is proved．
