Abstract

An impeller is secured to one end of a hollow shaft and is positioned within a chamber to which air is supplied. An output line from the chamber is joined with the intake manifold of an engine. The opposite end of the hollow shaft is immersed in fuel. When a vacuum is drawn by the manifold, air flow through the chamber rotates the impeller while fuel is simultaneously drawn through the shaft and discharged into the chamber. The turbulence and agitation of the impeller atomizes the fuel so that an air/fuel mixture is supplied to the manifold through the output line. Pressurized air is applied to the fuel as it rises in the hollow shaft to provide initial fuel atomization.
