Abstract
A system according to the principles of the present disclosure includes an airflow determination module and a cylinder activation module. The airflow determination module determines an amount of airflow through a ventilation system for a crankcase of an engine. The cylinder activation module, when a cylinder of the engine is deactivated while the engine is running, selectively activates the cylinder based on the amount of airflow through the ventilation system.
