Abstract
An intake system for an internal combustion engine wherein an intake conduit (16) within a cylinder head (14) is configured to receive a vane control module (24). The vane control module (24) includes a vane (34) mounted within an airflow conduit (30). An actuator (36) pivots the vane (34) to different positions depending upon engine operating conditions. Under high load engine operating conditions, with the vane (34) in a fully retracted position, minimum restriction to the fluid flow is achieved, and in-cylinder tumble flow is created due to the shape and orientation of the vane 34. Under low load engine operating conditions, with the vane (34) in an extended position, the vane (34) causes a redirection of the fluid in order to create a swirl flow pattern in the cylinder (12).
