Abstract:
Systems and methods for determining when one or more cylinders of an engine may be deactivated are presented. In one example, different cylinder deactivation strategies are used to determine which engine cylinders are deactivated during an engine cycle in response to an actual total number of valve actuator state changes being greater than a first threshold.
