ABSTRACT:
In an internal combustion engine equipped with an injector for cylinder-inside injection to inject fuel into a cylinder and an injector for intake port injection to inject fuel into an intake port, both the injectors being switched for use depending upon operating conditions, wherein when an operating condition range using either one of the first or the second injector is switched to an operating condition range using the other one thereof, the amount of fuel to be injected by the either one of the first or the second injector is gradually decreased and the amount of fuel to be injected by the other one is gradually increased over a predetermined period during the switching. Further, at the time of the switching, at least one of ignition timing and throttle opening angle is gradually varied.
