Abstract
A control system for an internal combustion engine having at least one fuel injection valve for injecting fuel into a combustion chamber of the engine. A compression end temperature in the combustion chamber is estimated. A target compression end temperature is calculated according to an operating condition of the engine. A main injection and a plurality of pilot injections before the main injection are performed by at least one fuel injection valve. A fuel injection amount in a first-performed pilot injection of the plurality of pilot injections is controlled so that the estimated compression end temperature coincides with the target compression end temperature.
