ABSTRACT:
A control system for an internal combustion engine having a fuel injector located in a combustion chamber of the engine for injecting fuel into the combustion chamber. The fuel injection timing stored in a fuel injection timing map is retrieved according to the detected engine operating condition to determine the fuel injection timing. An actual ignition timing of the fuel injected into the combustion chamber is detected. An ignition delay of the actual ignition timing with respect to the target ignition timing, which is set according to the engine operating condition and a fuel injection timing correction amount, is calculated according to the calculated ignition delay. The fuel injection timing is corrected with the fuel injection timing correction amount, and the fuel injection is executed according to the corrected fuel injection timing.
