Control apparatus for internal combustion engine

A control apparatus for an internal combustion engine, comprising:

• a fuel injection valve that injects a fuel into intake air of the internal combustion engine;
• a supercharger that has a turbine provided in an exhaust passage and a compressor provided in an intake passage of the internal combustion engine, and that supercharges intake air utilizing an exhaust pressure;
• a waste gate valve that adjusts an amount of exhaust gas that flows by bypassing the turbine of the supercharger;
• a fuel adherence amount calculation device that calculates a wall-surface fuel adherence amount that is an amount of fuel adhering to a wall surface of the internal combustion engine among the fuel injected from the fuel injection valve, and that acquires a degree of opening of the waste gate valve or an indicator corresponding to the degree of opening as a WGV parameter and calculates the wall-surface fuel adherence amount based on at least the WGV parameter;
• and
• a fuel adherence amount reflecting device that causes the wall-surface fuel adherence amount to be reflected in a fuel injection amount that is set based on an operating state of the internal combustion engine.
