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, and an exhaust gas recirculation mechanism for recirculating a portion of exhaust gases from the engine to the combustion chamber. The exhaust gas recirculating mechanism includes an exhaust cooler for cooling the recirculated exhaust gases. A target ignition timing of the fuel injected by the fuel injection valve is calculated. An actual compression ignition timing of the fuel injected by the fuel injection valve is detected. Operation of the exhaust cooler is controlled based on the target ignition timing and the actual compression ignition timing.
