| Abstract: | Using PWM to control the dualistic three way high-speed solenoid valve, it has the flexibility to be able to fuel injection quantity, fuel injection control in time. The control process of diesel common rail electronic control system was studied by PWM, main in the structure of high-speed switch, PWM principle, the dynamic response of the high-speed switch controlled by PWM signal, which was produced by the electronic control unit. |
