Abstract
Various systems and methods are described for controlling engine operation. One method comprises, during a first variable displacement engine (VDE) mode in an engine having four cylinders, deactivating a first cylinder of the four cylinders and firing a second, third, and fourth cylinder of the four cylinders, each firing event separated by 240 degrees of crank angle (CA). The engine may be operated in a non-VDE mode by activating the first of the four cylinders and firing the first cylinder between the third and fourth cylinders.
