ABSTRACT:
The device includes a pair of flat planar vanes securely mounted within a cylindrical housing. The vanes have a medial slit extending from the center to a longitudinal end of the vane. The vanes are interconnected at the slits so that they are in criss-cross positioning. The vanes are axially angled so that when positioned in an intake air duct the vanes impart a swirling motion to the air entering the engine providing more complete mixing of the air and fuel and when positioned in an exhaust passageway the vanes impart a swirling motion to the exhaust gases exiting the engine providing scavenging of the exhaust gases.
