ABSTRACT:
A control apparatus of an internal combustion engine includes a fuel pressure sensor to detect the pressure of the fuel supplied from a fuel pump to an injector; an in-cylinder pressure sensor, which serves as a combustion chamber temperature detecting unit that detects the temperature in the combustion chamber or the parameter depending on the temperature, to detect in-cylinder pressure (combustion chamber pressure); and an ECU that controls to execute the first fuel injection of each cylinder by the injector when the fuel pressure detected by the fuel pressure sensor is not less than a predetermined threshold fuel pressure and when the in-cylinder pressure detected by the in-cylinder pressure sensor is not less than a threshold in-cylinder pressure.
