摘要： Apparatus and methods for hydraulic valve actuation of engine valves are disclosed. An exemplary embodiment of the present invention may include a lost motion piston assembly that transfers motion between first and second rocker arms to selectively provide auxiliary engine valve actuation motions to the engine valves for engine operations such as engine braking and exhaust gas recirculation. The lost motion piston assembly may reduce or eliminate transient loads that may otherwise be transmitted to engine valve train elements during the times that lost motions systems are turned on and off for auxiliary valve actuations.

摘要： Systems and methods of actuating engine valves using a hydraulic valve actuation system are disclosed. The valve actuation system includes a master piston and two slave pistons slidably disposed in bores provided in a housing. The master piston and two slave pistons are connected together by a hydraulic circuit. Linear motion imparted to the master piston is transferred to the two slave pistons via the hydraulic circuit. In turn, the two slave pistons may actuate one or more engine valves directly or through an intermediate valve bridge. A valve seating device may be provided to assist in seating the engine valves in embodiments where the valve actuation system is adapted to provide variable valve actuation.

摘要： Systems and methods for actuating engine valves are disclosed. The systems may include primary and auxiliary rocker arms disposed adjacent to each other on a rocker arm shaft. The primary rocker arm may actuate engine valves for primary valve actuation motions, such as main exhaust events, in response to an input from a first valve train element, such as a cam. The auxiliary rocker arm may receive one or more auxiliary valve actuation motions, such as for engine braking, exhaust gas recirculation, and/or brake gas recirculation events, from a second valve train element to actuate one of the engine valves. Master and slave pistons may be provided in the primary rocker arm. The master piston may be actuated by the auxiliary rocker arm.

摘要： A cam may be provided with a main exhaust lobe and a compression-release or partial bleeder lobe and a base circle portion between the two lobes. A rocker arm including an internal rocker passage may be operatively connected to the cam. The rocker arm may contact a valve bridge at a central portion. The valve bridge may be operatively connected to first and second engine valves at its first and second ends, respectively. A slave piston incorporated into the first end of the valve bridge and a master piston may be incorporated into the central portion of the valve bridge. The master and slave pistons may be selectively actuated and the bleed hole may be selectively blocked and unblocked to provide compression-release or partial bleeder braking as a result of the valve actuation motion imparted from the cam to the valve bridge through the rocker arm.

摘要： The present invention is directed to a system and method for actuating an engine valve. In one embodiment, the present invention is a system for providing exhaust gas recirculation (EGR) in an engine having at least one engine valve, the system comprising: means for imparting a valve train motion; a first valve actuation subsystem for transferring motion from the motion imparting means to the engine valve, the first valve actuation subsystem capable of providing valve actuation for at least a portion of a main exhaust event during a first engine operating condition, and a full main exhaust event during a second engine operating condition; and a second valve actuation subsystem for transferring motion from the motion imparting means to the engine valve, the second valve actuation subsystem capable of providing valve actuation for an exhaust gas recirculation event during the first engine operating condition.
