Abstract
A startup control apparatus of an internal combustion engine is provided wherein when an engine starting capability determining device determines that the engine can be successfully started even if driving of part of the fuel injector valves is stopped during engine startup, the fuel injection is stopped with respect to the part of the fuel injector valves. With this arrangement, overshoot of the engine speed that would otherwise occur upon the start of the engine can be suppressed, and unburned fuel components can be prevented from being discharged, thus assuring improved exhaust gas characteristics and improved fuel efficiency.
