During high-load running of a vehicle, first control is performed wherein fuel injection is carried out in an intake stroke of an engine so as to evenly distribute mixture gas into combustion chambers of the engine. During low-load running of the vehicle, second control is performed wherein fuel injection is carried out in a compression stroke of the engine so as to bias mixture gas toward a zone in the vicinity of an ignition plug of the engine. The first control and the second control are switched over from one to the other in accordance with a loaded condition of the engine. Even if the engine has reached a loaded condition suited for a transition to the first control due to sudden acceleration during performance of the second control, while transient surge damping control based on an opening degree of a throttle valve is being performed, the transition to the first control is not made. |
