摘要：An engine with an efficient valve actuator is disclosed. The engine employs afirst force to hold a valve of the engine open during a normal valve event and a secondforce to hold the exhaust valve open during an exhaust gas recirculation event. The valveactuator may be operated using pressurized fluid adapted to extend an actuator plungerthrough a cylinder. The first force may be derived by a mechanically driven actuator, whilethe second force may be derived from a high pressure rail of the engine. A control valvemay be employed to direct either low pressure or high pressure oil to the valve actuatorcylinder.
