An internal combustion engine (1) is provided with a supercharger (12) and a cylinder direct injection fuel injector (10). When the engine shifts in a low-speed supercharging region at a state where the wall temperature of a cylinder bore (3) is low, liquid fuel adheres to a wall surface of the cylinder bore (3) so that lubricating oil is diluted with the liquid fuel and released into a combustion chamber (4). As a result, there occurs abnormal combustion. In the present invention, the fuel injection amount is increased at the time when the engine shifts in a predetermined low-speed supercharging region. The lower the wall temperature of the cylinder bore, the larger the rate of increase of the fuel injection amount. This makes it possible to suppress the temperature of air-fuel mixture in the vicinity of compression top dead center and prevent the occurrence of abnormal combustion.
