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.
Claims26
A fluid swirling device for insertion in intake system of an internal combustion engine, comprising:
- a housing;
- a set of vanes mounted within said housing, each vane of said set of vanes having a medial slit extending partly along a length of said each vane, said set of vanes interconnected together at the slits, said set of vanes being entirely flat planar.
A fluid swirling device for insertion in intake system of an internal combustion engine, comprising:
- a cylindrical housing open at longitudinal ends thereof and circumferentially closed;
- a set of vanes mounted within said housing, each vane of said set of vanes having a medial slit extending partly along a length of said each vane, said set of vanes interconnected together at the slits, the slit of each vane extending in an axial direction, said set of vanes having a set of pairs of appendages at lateral edges thereof and said housing having a set of pairs of apertures for receiving said set of pairs of appendages in order to secure said set of vanes to said housing, each pair of apertures oriented at an angle of aperture inclination relative to direction of flow of fluid stream entering said housing in order to position said set of vanes at angles of end vane portion inclination equal to said angle of aperture inclination.
A fluid swirling device for insertion in an exhaust system of an internal combustion engine, comprising:
- a housing;
- a set of vanes mounted within said housing, each vane of said set of vanes having a medial slit extending partly along a length of said each vane, said set of vanes interconnected together at the slits said set of vanes being entirely flat planar.
A fluid swirling device for insertion in exhaust passageway of an internal combustion engine, comprising:
- a cylindrical housing open at longitudinal ends thereof and circumferentially closed;
- a set of vanes mounted within said housing, each vane of said set of vanes having a medial portion and a medial slit extending partly along a length of said each vane, said set of vanes interconnected together at the slits, said set of vanes being entirely flat planar, the slit of each vane extending in an axial direction so that said medial portion of said each vane oriented in an axial direction, said set of vanes having a set of pairs of appendages at lateral edges thereof and said housing having a set of pairs of apertures for receiving said set of pairs of appendages in order to secure said set of vanes to said housing, each pair of apertures oriented at an angle of aperture inclination relative to direction of flow of fluid stream entering said housing and relative to said medial portion in order to position said set of vanes at angles of end vane portion inclination equal to said angle of aperture inclination.
