ABSTRACT:
A control device of an internal combustion engine suppressing catalyst deterioration by prohibiting fuel cuts, wherein the generation of odor from the catalyst after deceleration is suppressed. The control device is provided with a fuel cut executing device for stopping the supply of fuel to an internal combustion engine when a vehicle is in a decelerating state and a fuel cut prohibiting device for prohibiting a fuel cut when a temperature of a catalyst provided in an exhaust system is a predetermined temperature or more, wherein when a fuel cut is prohibited by the fuel cut prohibiting device when the vehicle decelerates in a predetermined period after an increased fuel operation is performed, the internal combustion engine is operated so that the combustion air-fuel ratio becomes lean in the decelerating state or in the decelerating state and its succeeding idling state.
