Abstract:
Systems and methods for operating an engine with a plurality of deactivating valves for deactivating engine cylinders are presented. In one example, a plurality of different cylinder operating modes may be available to operate the engine. Engine fuel consumption in each of the plurality of different cylinder operating modes is estimated and the engine may be operated in the cylinder mode that provides greatest fuel efficiency.
