Abstract
An engine speed control system for an internal combustion engine mounted on a vehicle comprises an actuator for actuating a throttle valve for increasing and decreasing the idling speed, an ignition switch for producing a signal during the operation of the engine, an engine speed signal generating circuit, an engine speed increasing signal generating circuit and an engine speed decreasing signal generating circuit, an actuator control circuit for operating the actuator in opposite directions in accordance with engine speed increasing and decreasing signals, a vehicle speed signal generating circuit, and an idling signal generating circuit for generating an idling signal in the idling operation of the engine. A stop switch is provided for producing a signal when the throttle valve reaches the closed position. A logic gate means is provided to be operated by the vehicle speed signal, idling signal, signal of the ignition switch and signal of the stop switch for turning off the actuator control circuit for stopping the operation of the actuator.
