Injector Actuation Circuit

without comments

In order to improve injector responsiveness, the actuation voltage has been changed to high voltage, speeding up both solenoid magnetization and the response of the TWV. The EDU or the charge circuit in the ECU raises the respective battery voltage to approximately 110V, which is supplied to the injector by signal from the ECU to actuate the injector.
