<p>A device (10) for the passive variation of a fluid stream characteristics of an air fluid stream entering an engine featuring body having an interior cavity which communicates with an intake aperture (16), an outlet aperture (18) located upon the body portion and defines a fluid stream passageway through the body. The outlet aperture (18) cross-sectional area is adjusted by vanes (14) formed by a plurality of slits (12) at an inward curve in the wall having a calculated bias toward the center axis point of the outlet aperture (18). The cross-sectional area of the outlet aperture (18) formed by the biased vanes (14) varies from a smaller area when the volume of air fluid stream therethrough is low to a larger area when the volume of the air fluid stream is increased sufficiently wherein the force thereof overcomes calculated bias of the inward biased vanes (14) optimizing the air fluid flow intake into an internal combustion engine.</p> |
