摘要： A ranking module determines N ranking values for N predetermined cylinder activation/deactivation sequences of an engine, respectively. N is an integer greater than or equal to two. A cylinder control module, based on the N ranking values, selects one of the N predetermined cylinder activation/deactivation sequences as a desired cylinder activation/deactivation sequence for cylinders of the engine. The cylinder control module also: activates opening of intake and exhaust valves of first ones of the cylinders that are to be activated based on the desired cylinder activation/deactivation sequence; and deactivates opening of intake and exhaust valves of second ones of the cylinders that are to be deactivated based on the desired cylinder activation/deactivation sequence. A fuel control module provides fuel to the first ones of the cylinders and disables fueling to the second ones of the cylinders.

摘要翻译： 排序模块分别确定发动机的N个预定气缸启动/停用序列的N个排序值。 N是大于或等于2的整数。 气缸控制模块基于N个排序值，选择N个预定气缸启动/停用顺序中的一个作为发动机气缸的期望气缸启动/停用顺序。 气缸控制模块还：基于所需的气缸启动/停止顺序，激活要启动的第一气缸的进气门和排气门的打开; 并且基于期望的气缸激活/去激活顺序来停用要被去激活的第二个气缸的进气门和排气门的打开。 燃料控制模块向第一气缸提供燃料，并且禁止向第二气缸供油。
