EFFICIENT INTERNAL COMBUSTION ENGINE VALVE ACTUATOR

An engine with an efficient valve actuator is disclosed. The engine employs a first force to hold a valve of the engine open during a normal valve event and a second force to hold the exhaust valve open during an exhaust gas recirculation event. The valve actuator may be operated using pressurized f...

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