エンジン。In a multi-cylinder engine equipped with a cutoff valve that cuts off the supply of fuel and fresh air to some cylinders in the engine light load range, etc., and a fresh air introduction valve that guides fresh air downstream of the cutoff valve when the cylinder is inactive, Means for detecting a deceleration state and means for detecting engine speed are provided, and when the engine speed is above a predetermined value during deceleration, the shutoff valve is opened and the fresh air introduction valve is closed to supply fuel to all cylinders. control means, which starts supplying fuel to a specific cylinder in the following conditions, and when the rotational speed further decreases, closes a cutoff valve, opens a fresh air introduction valve, and resumes fuel supply to other cylinders. The engine is equipped with a cylinder number control system.
