Zusammenfassung:The disclosure is directed at a valvetrain actuation (VA) system for an engine comprising at least two hydraulic rotary valves connected to an engine crankshaft, at least one hydraulic actuator driven by the at least two hydraulic rotary valves, and a high pressure hydraulic fluid source for supplying hydraulic fluid to one of the at least two hydraulic rotary valves, wherein movement of the at least two hydraulic rotary valves by the engine crankshaft allows hydraulic fluid to flow to the at least one hydraulic actuator to actuate an engine valve.
