PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine with a supercharger, capable of providing the best exhaust emission characteristic. SOLUTION: A blowout quantity of fresh air to an exhaust system is calculated (Step 102), and an after-burning injection quantity such as the air-fuel ratio becomes the target air-fuel ratio when the fresh air equivalent to this blowout quantity causes after-burning in the exhaust system, is calculated (Step 106). This target air-fuel ratio is the air-fuel ratio of becoming maximum in the exhaust temperature by after-burning and becoming the best in an exhaust emission characteristic by after-burning. A cylinder for injecting fuel equivalent to the after-burning injection quantity is set in response to a comparison between a counter CCRNK and reference values A1, B1, C1 and D1 (Step 110 to 124).
