燃機関の補助空気量制御装置。 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 the suction side pressure of the compressor, wherein the air conditioner correction amount setting means is an air conditioner operation controller that determines whether the air conditioner is activated or not. a determination means; a compressor suction side pressure detection means for detecting the suction side pressure of the compressor;
An auxiliary air amount control device for an internal combustion engine, comprising an air conditioner correction amount variable means for variably setting an air conditioner correction amount based on the suction side pressure of a compressor when the air conditioner is operating.
