Abstract
An internal combustion engine is provided with a fuel injection valve. The fuel injection valve is actuated so that fuel injected therefrom reaches the combustion chamber in the latter half of the intake stroke, thereby accomplishing stratified charge. The timing at which blow-back of intake gas occurs is detected and the timing for terminating fuel injection is advanced as the timing at which blow-back of intake gas occurs becomes earlier.
