ABSTRACT:
A fuel control system for a cylinder direct injection internal combustion engine. A predetermined portion of the fuel spray is appropriately ignited regardless of the correction of the ignition timing, thereby always securing stable, satisfactory combustion. In the case where the ignition timing is corrected, the fuel injection timing is corrected in accordance with the ignition timing correction amount. The fuel injection timing is corrected also with the change in the internal cylinder pressure and the fuel injection velocity taking the intake pipe pressure and the fuel pressure into account, thereby maintaining the required ignition point of the fuel spray.
