ABSTRACT:
A dedicated compression braking system is provided having at least one engine piston reciprocally mounted within a cylinder for cyclical successive compression and expansion strokes and at least one exhaust valve operable to open in a variable timed relationship with an engine piston compression stroke when the engine is operated in a compression braking mode. The braking system includes an independent exhaust valve actuator assembly, including a braking mode rocker lever and a cam lobe for imparting reciprocable movement to the exhaust valve when the engine is operated in the braking mode. The second exhaust valve actuator assembly includes a braking fluid circuit formed in the braking mode rocker lever and a braking fluid valve and three-way solenoid valve mounted on the braking mode rocker lever for controlling the flow of braking fluid in the braking mode rocker lever during compression braking. The dedicated braking system minimizes the size and weight of the engine and also permits maximum freedom in designing and controlling the operation of the braking system independent of other engine components to maximize the efficiency of compression braking.
