Abstract

Various exemplary illustrations of a camshaft assembly for actuating valves of an engine are disclosed. The camshaft assembly may include a camshaft having a plurality of lobes, including at least one phase adjustable lobe configured to be selectively rotated with respect to the camshaft. The assembly may further include a hydraulic valve actuator in communication with a first lobe of the camshaft. The hydraulic valve actuator may be configured to selectively actuate at least one valve in communication with the hydraulic valve actuator in response to the at least one cam lobe.
