ABSTRACT:
An engine control system includes a scavenging module that generates a scavenging signal when both a driver torque request is greater than a predetermined torque threshold and a rotational speed of an engine crankshaft is less than a predetermined speed threshold. A cam phaser control module controls intake and exhaust cam phasers based on the scavenging signal such that opening times of intake and exhaust valves of a respective cylinder overlap.
