  • Applied lost motion for optimization of fixed timed engine brake system
    Patent number: 5996550
    Abstract: An internal combustion engine may include a hydraulic linkage used to transfer motion from a valve train element, such as a cam, to an engine valve. Method and apparatus for selectively limiting the motion transferred by the hydraulic linkage from the valve train element to the engine valve are disclosed. The hydraulic linkage may comprise means for resetting or clipping the displacement of the engine valves into the engine cylinder following a compression release event. The hydraulic linkage may also limit the displacement of the engine valves into the engine cylinder for main exhaust and/or other valve events, as well as limit the overlap between a main exhaust valve event and an intake valve event.
