Claims

[Scope of utility model registration request]

An auxiliary air amount control device for an internal combustion engine that is equipped with an auxiliary air control valve in an auxiliary air passage that bypasses a throttle valve, and controls the amount of auxiliary air by controlling the amount of control to the auxiliary air control valve. A basic control amount setting means that sets a basic control amount based on water temperature, an air conditioner correction amount setting means that sets an air conditioner correction amount when the air conditioner is activated, and a feedback correction that compares the engine speed with the target idle speed when idling. a feedback correction amount setting means for setting the amount; and a control amount for calculating the final control amount to be output 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. and the air conditioner further includes a variable capacity compressor whose capacity changes depending on at least the outside temperature, the air conditioner correction amount setting means;
Consisting of an air conditioner operation determination means for determining whether the air conditioner is activated or not, an outside temperature detection means for detecting the outside temperature, and an air conditioner correction amount variable means for variably setting the air conditioner correction amount based on the outside temperature when the air conditioner is activated. An auxiliary air amount control device for an internal combustion engine, characterized by:
