Abstract:
1. A device for creating a vortex of air passing through a cylindrical air intake passage of an engine so that the vortex reaches the combustion chamber of the engine, comprising: a cylindrical outer skirt having a top edge, a bottom edge, a slit passing from the top edge to the bottom edge and a plurality of symmetrically located holes between the top and bottom edges, each of the holes comprising at least a first edge, a second edge parallel to the first edge, a bottom edge, and a curved top edge, wherein the first edge is slanted at an angle of 45 degrees with respect to the longitudinal axis passing through the center of the cylindrical skirt; and a plurality of identical and symmetrically arranged vanes projecting inwardly from the inner surface of the skirt and toward the center of the skirt, leaving the longitudinal central portion of the skirt free of the vanes, each of the vanes comprising; a first planar section having at least a first side being in connection with the first edge of the hole in the cylindrical skirt, a second side parallel to the first side, a top side, and a bottom side, the first planar section is perpendicular to the inner surface of the cylindrical skirt and slanted at an angle of 45 degrees with respect to the longitudinal axis passing through the center of the cylindrical skirt; a second planar section having at least a first side, a second side, and a bottom side being in connection with the top side of the first planar section, the first and second sides intersect to form a curved profile, the second planar section projects at an angle of 45 degrees from the first planar section towards the second edge of the hole to which the first side of the first planar section is connected; wherein the orientations of the first and second planar sections facilitate in directing the airflow into a vortex configuration.
