。A third valve provided separately from the normal intake valve and exhaust valve in one or more cylinders of a vehicle engine or the above-mentioned exhaust valve is opened near the compression top dead center of the piston when the vehicle is running under engine braking. The exhaust brake valve is configured to discharge the compressed air inside the cylinder to the outside of the cylinder, and an exhaust brake valve is provided in the exhaust pipe between the engine and an exhaust gas turbine driven by the exhaust gas of the engine to control the flow area of the exhaust pipe. When the vehicle is running under engine braking, the exhaust brake valve is substantially fully opened in the low engine speed range, and the exhaust brake valve is partially opened in the high engine speed range to reduce the pressure in the exhaust pipe. The exhaust valve of the engine is configured to maintain the pressure below the self-opening/closing pressure, further dividing the exhaust gas introduction passage of the exhaust gas turbine into a plurality of passages, and providing a valve device in at least one of the divided passages,
An engine brake device characterized in that the valve device is configured to close when the exhaust brake valve is partially opened.
