PROBLEM TO BE SOLVED: To keep constant an injection ratio between synchronization and asynchronization of sucking air even when the engine speed changes, so as to optimumly control the combustion state of an internal combustion engine. SOLUTION: The system is provided with a fuel injection valve 30 for injecting fuel to an air intake passage 12 of the internal combustion engine 10, an intake air valve 36 provided in the air intake passage 12 of the internal combustion engine, a variable valve train 44 for changing the switching timing of the intake air valve 36, and a compensation means for compensating the opening timing of the intake air valve 36 so that the ratio of time (injection ratio) of the asynchronization of sucking air in which the fuel is injected while the intake air valve 36 is closed to the synchronization of sucking air in which the fuel is injected while the intake air valve is opened may be kept constant.
