Abstract

A system (10) and method for actuating an engine valve (700) to provide engine braking and/or exhaust gas recirculation using a common source of hydraulic fluid is disclosed. The system (10) receives high-pressure hydraulic fluid from a common rail system, such as those used to provide fuel injection. The fluid pressure is reduced before being used to actuate an engine valve for engine braking or EGR. Preferably an engine valve (700) that is dedicated to the engine braking or EGR function is provided in the engine. The dedicated engine braking/EGR valve may be driven by an electromagnetic (690) actuator in an alternative embodiment.
