Abstract
An air rotor within the carburetor bore and rotated by air drawn into the bore during engine operation has extremely small diameter fuel jets associated therewith that inject fuel into the bore in counterflow relationship to the inrush of air, thereby markedly increasing atomization. In addition, the jets are directed to inject the fuel into the bore in a forward direction with respect to the direction of rotation of the rotor, hence propelling the fuel against the force of air in the bore to thereby further promote atomization. These features function independently and in cooperation with one another to increase engine operating efficiency and decrease the level of polluting emissions.
Claims6
In a carburetor for use with an internal combustion engine, said carburetor having an air horn defining a central bore, an air rotor rotatable within said bore in response to ambient air drawn into and through the bore during engine operation, at least one liquid fuel discharge jet on the rotor and rotatable therewith, and means for supplying the jet with liquid fuel during said rotation of the rotor, the improvement comprising:
- said jet being positioned to direct a stream of fuel forwardly with respect to the direction of rotation of the rotor and therefore against the force of air within the bore,
- said jet being disposed in close proximity to the periphery of the bore,
- said jet also being directed at least partially radially inwardly toward the axis of rotation of the rotor,
- said jet also being directed at least partially in counterflow relationship to the normal direction of travel of air through the horn.

- said jet being positioned to direct a stream of fuel in at least partial counterflow relationship to the normal path of travel of air through the horn,
- said jet also being positioned to direct the stream forwardly with respect to the direction of rotation of the rotor and, therefore, against the force of air within the bore,
- said jet being disposed in close proximity to the periphery of the bore,
- said jet also being directed at least partially radially inwardly toward the axis of rotation of the rotor.
