Abstract
A system according to the principles of the present disclosure includes a cylinder activation module and a spark timing module. The cylinder activation module selectively deactivates and reactivates a cylinder of an engine based on a driver torque request. When the cylinder is deactivated, the spark timing module selectively increases an amount by which spark timing of at least one active cylinder of the engine is retarded based on noise and vibration generated by the engine when the cylinder is deactivated.
