置。 The engine intake system includes a fuel injection valve, and includes intake air flow rate detection means for detecting the intake air flow rate to the engine, and fuel injection amount control means for controlling the fuel injection amount by the fuel injection valve based on the intake air flow rate. In addition, an auxiliary air control valve is provided in the auxiliary air passage that bypasses the throttle valve, and includes a deceleration detection means for detecting the deceleration state of the engine, and a deceleration detection means that sets the auxiliary air flow rate for deceleration air-fuel ratio correction at the time of deceleration. In an internal combustion engine equipped with an auxiliary air control means for deceleration air-fuel ratio correction that controls a control valve, the intake air flow rate given from the intake air flow rate detection means to the fuel injection amount control means during deceleration is determined by calculating the amount of deceleration air-fuel ratio correction from the detected value. A deceleration control device for an internal combustion engine, comprising a correction means for correcting the auxiliary air flow rate to a subtracted value.
