Abstract: A fuel atomizer adapted to be mounted between the carburetor and intake manifold of an internal combustion engine. The atomizer comprises a housing having mounted therein an impeller with blades having their leading edges disposed at a 45.degree. angle with respect to the horizontal plane of rotation of the impeller. Rotation of the impeller will effect a break up of the larger fuel droplets and to then mix with the incoming air. The impeller is provided with a specially designed spindle journalled for rotation in specially designed spindle bearings to thus insure a smooth operation of the impeller. The housing is also provided with a network of interconnected bars at the outlet end of the housing to effect a still further atomization of the air/fuel mixture as it leaves the housing responsive to the suction created in the intake manifold of the internal combustion engine.
