Control apparatus of internal combustion engine

A control apparatus of an internal combustion engine, comprising:

• a combustion chamber;
• an air-intake port and an exhaust port that communicate with the combustion chamber;
• an air-intake valve that opens and closes the air-intake port;
• an exhaust valve that opens and closes the exhaust port;
• a fuel injection unit that injects fuel into the combustion chamber;
• a fuel supplying unit that supplies fuel to the fuel injection unit;
• a fuel pressure detecting unit that detects a pressure of fuel supplied from the fuel supplying unit to the fuel injection unit;
• a combustion chamber temperature detecting unit that detects a temperature parameter of the combustion chamber;
• and
• a fuel injection control unit that causes the fuel injection unit to execute a first fuel injection when the pressure detected by the fuel pressure detecting unit is not less than a predetermined threshold fuel pressure and when the temperature parameter of the combustion chamber detected by the combustion chamber temperature detecting unit is not less than a predetermined threshold temperature.
