ABSTRACT:
A control system for an internal combustion engine having at least one fuel injection valve for injecting fuel to an intake pipe or a combustion chamber of the engine. Intake gas state parameters indicative of a state of the intake gases supplied to the engine are detected. Demand values of the intake gas state parameters are calculated according to operating condition parameters indicative of an operating condition of the engine. The intake gas state is controlled so that the intake gas state parameters coincide with the demand values. A control value is then calculated according to the operating condition parameters and deviations of the intake gas state parameters from the demand values. Accordingly, an amount of fuel injected by the at least one fuel injection valve is controlled according to the control value.
