Abstract: An apparatus and process for atomizing a fuel-air mixture in an internal combustion engine by causing the fuel-air mixture to be driven in a funnel-type flow pattern in a passageway located between the engine's carburetor and intake manifold. The passageway includes a foraminous member disposed therein having an aperture and a grommet-rim therefore which comprises an aerodynamic surface in the path of the fuel-air mixture. The aerodynamic surface causes the fuel-air mixture to be driven in a circular path adjacent the outer wall of the passageway. The swirling fuel-air mixture is then drawn through the foraminous member where it is further atomized and conveyed to the intake manifold.
