ABSTRACT:
The device includes a set of rotatable vanes and a set of stationary vanes which are mounted within a cylindrical housing. The set of rotatable vanes are connected to a post located at the axis of the housing and rotate relative to the post in response to the intake or exhaust fluid impinging on the vanes which are angled relative to the direction of flow of the fluid stream. The set of stationary vanes are rigidly secured to the post and also rigidly secured to the housing walls. The set of stationary vanes are positioned adjacent the set of rotatable vanes and are similarly angled relative to the direction of flow of the fluid stream in order to deflect the fluid stream and impart a swirling motion to the fluid stream in order to provide more complete mixing of the air/fuel mixture of the intake fluid stream or scavenging of the exhaust fluid stream. Tabs which extend radially outwardly from the housing ends secure the device within an intake or exhaust passageway.
