ABSTRACT:
A device for generating a vortex of the airflow passing through an air intake passage of an engine. The device comprises a cylindrical skirt, a plurality of holes in the cylindrical skirt and a plurality of vanes projecting inwardly from the inner surface of the cylindrical skirt. Each of the holes is defined by at least bottom, top, first and second side edges. Each of the vanes comprise a first planar section projecting at an angle from the first edge of the hole and a second planar section projecting at an angle from the first planar section. The device can be installed inside any cylindrical air intake passage. The orientation of the first and second planar sections of the vanes helps in converting the random airflow into a regular swirling motion, which increases the oxidation of fuel and improves the efficiency and fuel economy of the engine.
