Abstract
Various methods and systems are provided for a hydraulically actuated engine valve. In one example, a method includes receiving an indication of a temperature of an exhaust flow exceeding a threshold temperature. The method further includes responsive to the indication, increasing a flow, in a hydraulically actuated valve system having a valve and an actuator in thermal communication with the exhaust flow, of hydraulic fluid through the actuator, to manage a temperature of the actuator.
