Abstract
A control system for varying cylinder valve timing of an internal combustion engine is provided. The control system includes a cam phase actuator having first and second actuator ports to adjust a rotational phase of a camshaft relative to a crankshaft, a first control valve, a second control valve, and a dynamic regeneration valve. In one embodiment, the dynamic regeneration valve is configured to enable the cam phase actuator to switch between operating in an oil pressure actuated mode and a cam torque actuated mode when adjusting the rotational phase of the camshaft relative to the crankshaft.
