可変エンジンの制御装置。A normally open line cutoff valve is provided in the intake pipe and exhaust pipe of the cylinder where the fuel supply can be stopped, and the cylinder of the cylinder can be freely connected to and separated from the vacuum suction device via the suction pipe, so that the fuel supply can be stopped. A control device for an engine with a variable number of cylinders capable of maintaining the inside of a cylinder in a substantially vacuum state, the control device controlling the closing operation of the intake cutoff valve of the cylinder to which fuel supply is stopped when the engine shifts to reduced cylinder operation. The valve is closed for a predetermined period of time prior to the connection of the vacuum suction device, and when the engine shifts to cylinder increase operation, the intake cutoff valve of the fuel supply return cylinder is opened, the exhaust cutoff valve is opened, and vacuum suction is performed. 1. A control device for an engine with a variable number of cylinders, comprising a control device that outputs a control signal so as to delay separation of the device by a predetermined period of time.
