ジン。 An on-off valve separate from the intake valve and exhaust valve is provided in the engine cylinder, and a cold air generating device such as a vortex tube is connected to the fluid passage whose communication with the cylinder is controlled by the on-off valve. During engine braking, the on-off valve is opened near compression top dead center to release the compressed air in the cylinder to the outside of the cylinder, and communication between the cold air generator and the fluid passage is cut off by the switching valve. , for a vehicle, characterized in that during normal operation other than during engine braking, the on-off valve is opened for a desired period during the intake stroke, and the cold air generator and the fluid passage are communicated via the switching valve. engine.
