Patent ID: 7930092

Claim:
A control apparatus for an internal combustion engine, comprising: a fuel injection unit provided in the internal combustion engine; an ignition unit provided in the internal combustion engine; a crank angle detection unit that is provided in the internal combustion engine, and that outputs a crank signal each time a crankshaft rotates by a predetermined angle; a fuel pump used to supply fuel to the fuel injection unit; a booster unit that boosts a power supply voltage; an ignition discharge unit that charges an ignition condenser using the boosted power supply voltage, and discharges power with which the ignition condenser has been charged to the ignition unit at the ignition timings; and a control unit structured to control the fuel injection unit, the ignition unit, and the fuel pump, to ascertain ignition timings based on the crank signals output from the crank angle detection unit, and to perform a startup control sequence that comprising: fuel injection processing in which the fuel injection unit is driven so as to perform the initial fuel injection; voltage boosting processing in which, after the fuel injection processing, the booster unit is controlled so as to boost the power supply voltage; ignition processing in which, after the voltage boosting processing, the ignition discharge unit is controlled so as to discharge to the ignition unit the power with which the ignition condenser has been charged when the ignition timings arrive; and fuel supply processing in which, after the ignition processing, the fuel pump is driven so as to supply fuel to the fuel injection unit.
