Valvetrain control method and apparatus for conserving combustion heat
Abstract:
An engine control system includes a catalyst module and a cylinder module. The catalyst module determines a catalyst temperature. The cylinder module selectively switches operation of a first cylinder from a first engine cycle having four strokes to a second engine cycle having N times four strokes, based on the catalyst temperature, wherein N is an integer greater than one. A related method is also provided.
