Abstract
Engines and methods of controlling an engine may involve one or more fluidically driven actuators associated with engine intake and/or exhaust valves. In some examples, the actuators may be placed in flow communication with high pressure fluid from one source and/or low pressure fluid from another. Timing of valve closing/opening and use of an air supply system may enable engine operation according to a Miller cycle.
