摘要
A system according to the principles of the present disclosure includes a cylinder activation module and a spark control module. The cylinder activation module selectively deactivates and reactivates a cylinder of an engine. The cylinder activation module deactivates the cylinder after intake air is drawn into the cylinder and before fuel is injected into the cylinder or spark is generated in the cylinder. When the cylinder is reactivated, the spark control module selectively controls a spark plug to generate spark in the cylinder before an intake valve or an exhaust valve of the cylinder is opened.
