安全装置。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. This is a safety device for an engine with a variable number of cylinders that can maintain the inside of the cylinder in a substantially vacuum state, in which a normally open safety valve is provided in the suction pipe on the inlet side of the vacuum suction device, and the exhaust pipe line is shut off. The variable number of cylinders is characterized in that a pressure sensor is provided in the cylinder-side conduit of the valve or in the suction pipe, and the safety valve is closed when the pressure detected by the pressure sensor exceeds a set value. Engine safety equipment.
