  • Control arrangement for an engine exhaust brake
    Patent number: 4557233
    Abstract: An exhaust brake system for internal combustion engines includes an exhaust valve within the exhaust duct which is closed or opened for the braking of a vehicle during engine operation by means of an engine brake valve. A magnetic valve is arranged within the control duct and is controlled by an electrical circuit connected to a terminal of the ignition switch and to the positive terminal of the generator in such a manner that the exhaust valves are closed during the starting of the engine and when the engine is idling. The formation of white exhaust smoke during cold starting of the engine and the formation of blue exhaust smoke during idling of the engine is decreased.
