キ装置。 A third valve separate from the intake valve and the exhaust valve is provided in some or all cylinders of the engine, and the third valve is kept closed during normal operation other than when the vehicle is running under engine braking, and the engine of the vehicle is In an engine braking device that increases the engine braking effect by opening the third valve during braking, the third valve is attached to a valve guide that slidably guides a valve stem of the third valve when the third valve opens and closes. A pressurized air injection hole for injecting pressurized air is formed on the sliding surface side with the valve stem, and a pressurized air supply mechanism is provided to supply pressurized air to the pressurized air injection hole. Engine braking device.
