転数制御装置。 An auxiliary air control valve is provided in the auxiliary air passage that bypasses the throttle valve, and by controlling the amount of control to the auxiliary air control valve, the amount of auxiliary air is controlled and the idle speed is controlled.Idle speed control of an internal combustion engine The device includes a basic control amount setting means for setting a basic control amount based on engine cooling water temperature, an air conditioner correction amount setting means for setting an air conditioner correction amount when the air conditioner is activated, and an engine rotation speed set to a target idle rotation speed. A feedback correction amount setting means for comparing and setting a feedback correction amount, and a final control amount outputted to the auxiliary air control valve based on the basic control amount, air conditioner correction amount, and feedback correction amount set by the respective setting means. Further, in an air conditioner having a variable capacity compressor, the air conditioner correction amount setting means includes air conditioner operation determining means for determining whether the air conditioner is activated or not; and an air conditioner correction amount variable means that variably sets the air conditioner correction amount based on the basic fuel injection amount when the air conditioner is activated. An idle speed control device for an internal combustion engine, characterized in that:
