Abstract
An automatic stop and start control system for a multiple-cylinder internal combustion engine mounted on a vehicle is disclosed. The automatic stop and start control system performs a control for automatically stopping and restarting the engine according to operating conditions of the vehicle and the engine. Fuel is provided to at least one of the cylinders of the engine when an engine stop condition for stopping the engine is satisfied. Subsequently, the fuel supply to all of the cylinders of the engine is stopped. The fuel supply to at least one of the cylinders is immediately carried out at the time an engine restart condition for restarting the engine is satisfied.
