Duty cycle type solenoid valve operating principle
This complex driver usually requires several different logic and control supply voltages.
The larger the duty cycle is, the greater the average current in the magnetization coil is, and the greater the magnetic field intensity is, the greater the valve lift is, and the greater the opening of the side channel.
The duty cycle of the control pulse signal is determined by ECU, and the average current in the ECU magnetizing coil depends on the duty ratio
When the internal ground when the current through the solenoid valve, control valve to start Z.
When the ignition switch is on, the battery voltage is applied to the solenoid valve, but the ground loop by ECU control.
