Abstract
An engine control system includes a cylinder control module and a pump control module. The cylinder control module selectively deactivates cylinders of an engine. In response to a determination that at least one of the cylinders is deactivated, the pump control module: selectively increases a target displacement for an oil pump that is driven by a balance shaft of the engine; and selectively adjusts displacement of the oil pump based on the target displacement.
