摘要： A system for actuating one or more engine valves for positive power operation and engine braking operation is disclosed. In a preferred embodiment, an exhaust valve bridge and intake valve bridge each receive 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 disposed in the center of the valve bridge to actuate two engine valves through the bridge. The outer plunger of each valve bridge may be selectively locked to its valve bridge to provide positive power valve actuation. During engine braking, application of hydraulic pressure to the outer plungers may cause the respective valve bridges and outer plungers to unlock so that all engine braking valve actuations are provided from a rocker arm acting on one engine valve through the sliding pin.

摘要： A method for actuating one or more exhaust valves in an internal combustion engine during positive power operation is disclosed. The expansion stroke of an engine cylinder is effectively lengthened and the exhaust stroke is effectively shortened by delaying the opening and/or advancing the closing of the exhaust valve relative to conventional exhaust valve timing during the exhaust stroke. Selective variation of the exhaust stroke during positive power operation of the engine may reduce NOx production.
