Abstract
In a control apparatus applied to an internal combustion engine in which when an opening degree of a valve body of a waste gate valve is less than the predetermined opening degree, the extension line intersects a wall surface of an exhaust passage located upstream of the upstream side end face of the exhaust gas purification catalyst, the control apparatus controls the waste gate valve so that at the time of execution of fuel cut off processing, when the temperature of the exhaust gas purification catalyst is less than a predetermined temperature, the valve body is fully closed, whereas when the temperature of the exhaust gas purification catalyst is not less than the predetermined temperature, the opening degree of the valve body is made to a deterioration suppression opening degree which is larger than when the valve body is fully closed and which is smaller than the predetermined opening degree.
