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： 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 for providing compression-release and partial bleeder braking engine valve actuation are disclosed. In an embodiment of the present invention, 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. A hydraulic circuit may be provided between the master and slave pistons. 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： Systems and methods of actuating two engine valves associated with a common engine cylinder using one or more lost motion systems and one or more control valves are disclosed. The control valves are capable of selectively trapping hydraulic fluid in the lost motion systems for auxiliary engine valve actuations and selectively releasing the hydraulic fluid to default to cam controlled valve seating of the engine valves. The systems may provide a combination of main exhaust, compression release, exhaust gas recirculation and early exhaust valve opening in preferred embodiments.
