摘要：
A system and method are described for reducing engine vibration during cylinder deactivation in selected operating conditions. The method utilizes open valve deactivation to better match the cylinder pressure of deactivated cylinders to combusting cylinders. This mode is utilized, along with cylinder closed valve cylinder deactivation, to improve overall fuel economy, while at the same time reducing vibration felt by the vehicle driver.
