Abstract
A control device for an internal combustion engine, which makes the engine speed increased rapidly at the engine starting, converge to a target engine speed by a feed-back retard control of an ignition time, is disclosed. In the control device, if the ignition time when the engine speed converges at the target engine speed is in the advance side than a target ignition time, the ignition time is retarded to the target ignition time and an amount of intake air is increased.
