DESCRIPTION OF THE PRIOR ART It is known that an important suource of inefficiency in exhaust emissions in internal combustion engines arises from incomplete mixing of liquid fuel and air in the carburetor. Several types of apparatus have been devoloped to more optimally carburate fuel and air, including manifold preheaters, fuel injector means, superchargers, and compound carburetors. Each of these types is intended to increase the dispersion of liquid fuel in the carburetor chamber. However, each tends to add greatly to the complexity of the carburetor apparatus, and, accordingly, increases the delicacy of the carburetor. It has also been found that, at certain loads,
fuel consumption and thus emission rates may be adversely affected by the presence of these attachments.
Accordingly, it is an object of the present invention to provide an antipollution device operable to more completely carburate liquid fuel and air in internal combustion engines.
It is a further object of this invention to provide the antipollution device in a substantially conventional carburetor.
It is another object of this invention to provide antipollution carburetor means which does not employ moving parts therein. 1 These and other objects shall become apparent from the description following, it being understood that modifications may be made without affecting the teachings of the invention here set out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT:
Referring now to the drawings and more particularly to the FIG. 1, the antipollution device of this invention is shown to advantage and generally identified by the numeral 10. It is to be understood that the device 10 is intended to be mounted on the throat of an internal combustion engine (not shown) in the manner of a carburetor. It has been found to advantage to mount the device 14) between the engine throat and a carburetor (not shown) in the manner of a compound carburetor. The device 10 comprises liquid fuel tubes 11, a body plate 12, and nozzles 13. The supply tubes 11 are intended to conduct liquid fuel under pressure from a suitable source, such as a fuel pump (not shown), through suitable means, such as a supply tube 14 to the ducts 15 in the plate 12.
Referring to the FIG. 2, the plate 12 provides fluid supply ducts 15 to the nozzles 13, carrier means 16, and plate-mounting means 17. The nozzles 13 are carried substantially centrally in suitable holes 16, shown to advantage in the FIG. 3. The ducts 15 are disposed in the plate 12 from its terminal sides to the respective nozzle carrier holes 16. It has been. found to advantage to align the respective ducts 15 substantially tangent to the nozzle carrier holes 16 to facilitate circulation of liquid fuel in the nozzle 13 in the manner hereinafter described.
Referring now to the FIGS. 4 and 5, a typical nozzle 13 includes a cylindrical casing 18, fuel cups 19, and venturi cups 20. The casing 18 is formed by a pair of upstandingly, concentrically disposed cylindrical walls 21 and 21' and a pair of end walls 22 and 22' fastened at the upper and lower terminal ends of the walls 21 and 21'. The outermost cylindrical wall 21 is provided with a plurality of outwardly projecting, mountingpositioning brackets 23 operable to contact the plate 12 on its lowermost terminal side about the circumference of the nozzle carrier holes 16. The end walls 22 and 22 issue outwardly toward the respective terminal ends of the nozzle 13. The walls 21 and 21 and 22 and 22, thus formed, form a cylindrical chamber-like reservoir in the manner of a carburetor float chamber. As shown in the FIGS. 2 and 3, the ducts 15 are operable to supply the casing 18 with liquid fuel. The fuel cups 19 are disposed at intervals on the interior wall 21. Each fuel cup 19 is formed by a pair of side walls 24 fastened radially to the interior wall 21 and by a front wall 25 fastened to the terminal end opposite the interior wall contacting side of the side walls 24 and fastened at their lowermost terminal ends by a bottom wall 25' to the casing 18 distally from its lowermost terminal end. As shown in the FIGS. 41 and 5, the fuel cup 19 is open to the flow of air from above. It may also be seen that the wall 25 is inclined centrally from its lowermost terminal end to its uppermost terminal end. the fuel cups 19 are operable together to form a verturilike chamber in which a high-pressure region is formed above the fuel cup 19 and a low-pressure region is formed between and below the fuel cup 19. The interior casing wall 21 is provided with a fuel exitway 26 distally above the bottom wall 25' and centrally disposed between the side walls 24 of the fuel cup 19, with fuel exitways 26' disposed centrally and substantially behind the venturi cup 211, and with fuel exitways 26" dis posed distally at intervals below the uppermost terminal end of the wall 21 and centrally between the fuel cups 19, hereinafter described. Likewise, the upper end wall 22 is provided with a plurality of distally disposed entranceways 27. Each of the fuel cups 19 is provided with a carburation exitway 28 centrally disposed in the bottom wall 25'. In operation, air is drawn through the nozzles 13 in the direction indicated by the arrow in the FIG. 3, and the pressure of the air tends to draw fuel in aerosol form from the exitways 26, 26', 26" between the walls 21 and 21 and through the nozzle 13. It is to be understood that a portion of fuel from the ducts 15 tends to flow in a circular pattern around castings 18 21, between and distally below the upper terminal ends of the fuel cups 19. The venturi cups are geometrically similar to the fuel cups 19 with'the side walls 29 and upwardly, centrally inclined wall 30 forming a triangle at their respective uppermost terminal ends. As set out above, the venturi cup 20 may be supplied with fuel from a fuel exitway 26 disposed in the wall 21. The venturi cups 20 are operable to provide increased turbulence in the low-pressure region of the nozzle 13.
In operation, a nozzle 13 is supplied with fluid from the supply tubes 11 through the plate 12. Air flowing through the nozzle 13 tends to create a differential in which trubulence is increased by the configuration and juxtaposition of'the fuel cups 19, the venturi cups 20, and the lowermost terminal wall 22'. As shown in the FIGS. 1, 2 and 3, the device 10 may include a plurality of nozzles 13. lt is also to be understood that a simple device 10 may include a single nozzle 13.
Having thus described in detail a preferred apparatus which embodies the concepts and principles of the invention and which accomplishes the various objects, purposes and aimsthereof, it is to be appreciated and will be apparent to those skilled in the art that many physical changes could be made in the apparatus without altering the inventive concepts and principles embodied therein.
