Abstract
An electronic control unit adjusts an electronic throttle valve to a starting opening in a cold start mode of an engine, then maintains the opening of the electronic throttle valve so that an engine rotational speed detected by a crank angle sensor increases to a target rotational speed, and increases the opening of the electronic throttle valve and retards an ignition timing if the engine rotational speed is increased above the target rotational speed.
