速度制御装置。 An auxiliary air passage that bypasses the throttle valve of the engine is provided with an idle control valve whose opening degree is adjusted according to the amount of electricity supplied to the solenoid, and the auxiliary air flow rate is controlled by the opening degree of the idle control valve. Therefore, in an idle rotation speed control device for an internal combustion engine that controls the idle rotation speed to a target rotation speed, a solenoid temperature detection means for detecting the temperature of the solenoid of the idle control valve, and a temperature detected by the solenoid temperature detection means are provided. An idle rotation speed control device for an internal combustion engine, comprising: an energization amount correcting means for correcting and controlling the energization amount according to temperature.
