Abstract
Systems and methods for controlling operation of deactivated engine cylinders are presented. In one example, intake valve timing of deactivated engine cylinders is advanced to reduce amplitudes of intake pressure pulsations while exhaust valves of the deactivated engine cylinders are held closed. Further, intake valve timing of deactivated cylinders may be advanced responsive to output of an intake manifold pressure sensor.
