Abstract
Various methods and systems are provided for controlling a hydraulically actuated engine valve. In one example, a system includes a hydraulically actuated engine valve and an engine having a first hydraulic system. The system further includes a second hydraulic system, which is separate from the first hydraulic system, and where the second hydraulic system provides fluid pressure to actuate the valve.
