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.
