Latest Patents
One of his latest patents is the "Combined engine braking and positive power engine lost motion valve actuation system." This system is designed for actuating one or more engine valves for both positive power operation and engine braking operation. In a preferred embodiment, the system features an exhaust valve bridge and an intake valve bridge, each receiving valve actuations from two sets of rocker arms. Each valve bridge includes a sliding pin for actuating a single engine valve and an outer plunger located in the center of the valve bridge to actuate two engine valves through the bridge. The outer plunger of each valve bridge can be selectively locked to its valve bridge to provide positive power valve actuation. During engine braking, the application of hydraulic pressure to the outer plungers allows the respective valve bridges and outer plungers to unlock, enabling all engine braking valve actuations to be provided from a rocker arm acting on one engine valve through the sliding pin.
