Abstract
In automatically stopping and restarting an engine on the basis of the operating conditions of various parts in a vehicle, the automatic engine stop and restart are effected by cutting off a fuel system, but not cutting off an iginition system. More specifically, a fuel control valve is provided in a path for feeding fuel to a slow port, and this control valve is closed on condition that at least the vehicle speed is in the state of zero and other conditions of allowing the automatic engine stop and restart are not met. An ignition signal taken from the energized ignition system is used to ensure that the engine is not started when it is already running.
