    Abstract: 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.

    Abstract: A system and method for actuating one or more engine valves to produce one or more internal exhaust gas recirculation events is disclosed. The method of the present invention is a method of providing exhaust gas recirculation (EGR) in a multi-cylinder engine, each engine cylinder having at least one engine valve, intake and exhaust manifolds, and a valve actuator. The method comprises the steps of: imparting motion to the value actuator; actuating the engine valve of a first engine cylinder responsive to the imparted motion; determining a first and a second engine parameter level; modifying the imparted motion responsive to the level of the first engine parameter level and the second engine parameter level to produce an exhaust gas recirculation event.
