| Abstract: | According to the force needed for opening and retaining the solenoid valve, a new driving circuit is designed for solenoid valve for gas injection. This circuit can provide enough opening force and lower energy consumption and heat emission. The circuit for ignition is redesigned using new type IGBT module, system structure is thus simplified and component number is greatly reduced. Driving circuit for idle speed control valve using PWM signal is designed, which has functions such as over-current protection and current feedback. Tests show that compared with original electronic control system, the new system is smaller, more reliable and consumes less energy. |
