Abstract
An actuator control system for an internal combustion engine idling speed governor mounted on a vehicle includes an actuator for actuating a throttle valve, an ignition switch for producing an ignition turning off signal, an engine speed signal generating circuit, an engine speed increasing signal generating circuit, an engine speed decreasing signal generating circuit, an actuator control circuit for operating the actuator in opposite direction in accordance with engine speed increasing and decreasing signals. A time lag signal generating circuit is provided to be responsive to said ignition turning off signal to generate a signal after a predetermined time. A logic gate is provided to be responsive to the ignition turning off signal for operating the actuator control circuit so as to close the throttle valve from the idling open position to the closed position. Another logic gate is provided to be responsive to the time lag signal for operating the actuator control circuit so as to open the throttle valve from the closed position to the idling open position.
