Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of preventing clogging of a catalyst carrier for emission purification, by manganese oxide.SOLUTION: A control device of an internal combustion engine includes manganese inclusion information communicating means for communicating manganese inclusion information of a fuel of the internal combustion engine, and pressure loss estimating means for detecting pressure loss by a catalyst carrier of an exhaust passage. An exhaust temperature of the internal combustion engine is controlled so that a catalyst bed temperature of the catalyst carrier becomes higher than a prescribed value for a prescribed time (step S3, step S4;YES), and further a fuel injection amount of the internal combustion engine is controlled so that an air-fuel ratio has a rich condition (Step S6;YES) under a condition that the manganese inclusion information is communicated by the manganese inclusion information communicating means (step S1;YES), and a pressure loss value detected by the pressure loss estimating means is over a predetermined determination value (step S2;YES).
