Abstract
Engines and methods of controlling an engine may involve one or more cams associated with engine intake and/or exhaust valves. In some examples, shifting the rotational phase of one or more cams advances and/or delays timing of the opening and/or closing of valves. Timing of valve closing/opening and possible use of an air supply system may enable engine operation according to a Miller cycle.
