Claims
- 1. An air guide filter for an internal combustion engine, comprising:a pleated filter disposed between a pair of support rings; and an air guide disposed between the support rings, the air guide having holes, uniformly disposed about the air guide, each hole bounded by a section having a half-cone cross-sectional shape; wherein, when the air guide is placed at a certain elevation angle with respect to the support rings, and wherein air flowing through the filter through the air guide is guided and rotated, such that when mixed with fuel a uniform air-fuel mixture is generated.
- 2. The air guide filter of claim 1 wherein the air guide is placed on an inner part of the pleated filter.
- 3. The air guide filter of claim 1 wherein the air guide is placed on an outer part of the pleated filter.
- 4. The air guide filter of claim 1 wherein the plurality of sections are formed in the same direction.
- 5. The air guide filter of claim 4 wherein the plurality of holes force air flowing through the filter to generate columns of air flow, and wherein the direction of the sections bounding the holes define the air flow direction.
- 6. The air guide filter of claim 5 wherein the columns formed are in the same direction and are uniform such that all flow into an air channel leading into the combustion chamber of the engine is in the same direction and is uniform.
- 7. The air guide filter of claim 1 wherein the air guide can be placed in one of a plurality of elevation angles.
- 8. The air guide filter of claim 1 wherein the air guide is parallel to the pleated filter.
- 9. The air guide filter of claim 8 wherein the air guide can be placed in one of a plurality of elevation angles.
- 10. The air guide filter of claim 1 wherein the air guide is made from a material that is more rigid than a material forming the pleated filter.
- 11. The air guide filter of claim 1 wherein the air guide is made from metal.
- 12. The air guide filter of claim 1 wherein the air guide is separate from the pleated filter.
- 13. An air guide filter for an internal combustion engine, comprising:a filter medium; and an air guide disposed adjacent the filter medium, the air guide having holes uniformly disposed about its face, each hole bounded by a section having a half-cone cross-sectional shape, wherein the holes with sections are oriented at an angle, wherein air flowing through the filter through the air guide is guided and rotated by said holes and sections.
- 14. The air guide filter of claim wherein the air guide is parallel to the filter medium.
