Abstract
A control system for an internal combustion engine having at least one fuel injection valve for injecting fuel in a combustion chamber of the engine. A main injection and a pilot injection are performed through the at least one fuel injection valve, the pilot injection being performed before the main injection. A demand output of the engine is temporarily reduced upon a request for reducing an output of the engine. The output of the engine is reduced when the demand output is reduced. A control of the pilot injection corresponding to a state where the demand output is not reduced is performed when the demand output is reduced.
