(54) Starting control method and system for internal combustion engine


(57) A starting control method for an internal combustion engine (E) in which output of the engine (E) is transmitted to an external component through a flywheel (F), characterized in that if an engine rotating speed remains in a resonance rotating speed region of the flywheel (F) for a predetermined period when the engine starts, a divergence control for controlling a fuel injection to make the engine rotating speed diverge from the resonance rotating speed region is performed. According to this, problems caused by the resonance between the crankshaft and the flywheel (F) at the time of engine starting can be prevented.
