ABSTRACT:
A control device of an internal combustion engine is capable of controlling an air-fuel ratio to be lean based on an activity of oxygen occlusion properties to provide improved three-way catalytic performance. The control device comprises: a three-way catalyst disposed in an exhaust passage of an internal combustion engine; a part for operating a basic fuel injection quantity; a part for operating a compensation amount of a basic fuel injection quantity so that an air-fuel ratio upstream from the three-way catalyst is coincident with a target air-fuel ratio; a part for operating a fuel injection quantity compensated with a basic fuel injection quantity compensation amount; a part for detecting an activity of oxygen occlusion properties of the three-way catalyst; and a part for setting the target air-fuel ratio based on the activity of oxygen occlusion properties.
