ELECTRONIC CONTROLS FOR COMPRESSION RELEASE ENGINE BRAKES

摘要

Electronic controls for compression release engine brakes of the type having electrically controlled valves for selectively applying high pressure hydraulic fluid to hydraulic actuators which open exhaust valves in the associated internal combustion engine to produce compression release events in the engine. The electronic controls may produce signals for both opening and closing the electrically controlled valves. The electronic controls may monitor various operating conditions of the engine and the vehicle powered by the engine and may automatically modify the timing of the compression release events in accordance with those conditions.
