An ECU calculates a command injection amount based on a driving condition, and calculates an injection timing based on a detected fuel pressure. Further, the ECU calculates a provisional injection period, and calculates again an injection period based on the injection timing fuel pressure and the command injection amount when the injection timing fuel pressure is correctly detected.

1. A fuel injection apparatus comprising:an injector injecting fuel; a pressure accumulating pipe accumulating high-pressure fuel therein, and supplying the high-pressure fuel to said injector; a fuel pressure detecting means for detecting fuel pressure inside said pressure accumulating pipe; and a control means for controlling said injector to inject the fuel, wherein said control means calculates an injection timing of said injector based on the detected fuel pressure, and said control means calculates an injection period based on an injection timing fuel pressure at the injection timing.
