ABSTRACT:
The system and method for controlling an electomagnetically operated valve driving mechanism comprises an actuator, an actuator drive circuit, a lift sensor, an actuator control apparatus, and a micro-computer. The actuator includes a valve opening solenoid and a valve closing solenoid. The actuator control apparatus generates signals for energizing and deenrgizing the valve opening solenoid and the valve closing solenoid based on control data supplied from the lift sensor and the micro-computer. The feature of this system is to control the elecromagnetically operated valve driving mechanism only by the actuator control apparatus but not by the micro-computer in a precise and sophisticated manner, thereby a burden on the micro-computer can be lightened.
