Patent ID: 7997245

Claim:
A fuel injection control apparatus comprising: an internal combustion engine; a fuel injection unit provided in the internal combustion engine; an intake state detection unit that detects an intake state value indicating an intake state of the internal combustion engine, and that outputs an intake state signal; a control unit to which the intake state signal is input, that determines based on the intake state signal whether or not the internal combustion engine is on an intake stroke, and that controls the fuel injection unit so that an initial fuel injection is performed in order to start up the engine when the control unit determines that the engine is on an intake stroke, wherein: an intake pressure signal corresponding to the intake pressure inside an intake pipe of the internal combustion engine or an intake rate signal corresponding to the intake rate inside the intake pipe is used as the intake state signal; and after the control unit has been activated, the control unit controls the fuel injection unit so as to perform the initial fuel injection when a difference between an initial intake state value that is calculated based on the intake state signal and a current intake state value that is calculated at a predetermined cycle is equal to or greater than a predetermined value.
