Abstract

A fuel injection control for an internal combustion engine is provided. Fuel is injected into a cylinder of the internal combustion engine. The fuel injection is divided into main injection and pilot injection in advance of the main injection. An actual compression ignition timing is detected based on a combustion state in the cylinder. A fuel injection timing of the main injection is controlled based on the actual compression ignition timing. An amount of heat release based on the pilot injection is computed. A fuel injection amount of the pilot injection is corrected based on the computed heat release amount.
