Abstract

A control apparatus for an internal combustion engine is provided which performs intake air flow control for controlling an engine speed to a target engine speed during starting of the engine, by adjusting a throttle opening depending upon the engine speed. The control apparatus judges a degree of deterioration of a combustion state in the engine, based on a difference between a predetermined reference peak engine speed and an actual peak engine speed, and switches from the intake air flow control to ignition timing control for controlling the engine speed when the engine operates in a poor combustion state, at a point of time that is determined based on the degree of deterioration of the combustion state.
