置。In a variable cylinder engine that cuts off the fuel supply to some cylinders depending on the engine operating condition, and then stops the operation of the intake and exhaust valves of that cylinder, there is a valve in the intake manifold for the cylinder that can be stopped. An intake cutoff valve is provided that closes the pipe line when a signal is received and opens the pipe line when an open signal is provided.When the engine transitions from full-cylinder operation to reduced-cylinder operation, the intake cutoff valve is installed after the fuel is cut off and before the intake and exhaust valves stop operating. A close signal is input to the intake cutoff valve, and when transitioning from reduced-cylinder operation to full-cylinder operation, an open signal is input to the intake cutoff valve after the intake and exhaust valves return to operation and before fuel supply resumes. A sound insulation device for a variable cylinder engine, characterized in that it is configured to
