OLeary 57 ABSTRACT An improved gasoline engine fuel vaporizer which is used in conjunction with anormal carburetor to further vaporize the fuel and provide increased engine efficiency and performance. The device is built into a gasket which normally is mounted between the carburetor and intake manifold, and uses the manifold vacuum to draw air through holes onto a jet-edge ultrasonic whistle. The ultrasonic sound provides the vaporizing action on the fuel.
6 Claims, 5 Drawing Figures l ULTRASONIC CARBURETION ENCHANCER SUMMARY OF THEYINVENTION vaporized gasoline to vaporize them by the application of ultrasonic sound as follows:
One or more Jet-edge whistles is built into a carburetor mounting gasket such that the'physical size and dimensions of each produces ultrasonic sound in the kilohertz region. The partial vacuum which exists in the intake manifold-when the engine is running is used as a power source, or an external air pump can be used.
A Jet-edge whistle is created by forming a thin air stream and directing it upon a knife-edge. The air stream oscillates alternately above andbelow the blade edge at a frequency determined by (a) the air stream thickness and velocity and (b) the distance between the blade edge and the orifice from which-the air stream v emerges.
If these dimensions are designed to produce sound in the ultrasonic region, andthe sound is directed at a fuel-air mixture, itserves to disperse and further evaporate fuel in the mixture The location selected for operation of the device was between the carburetor mounting flange and the intake manifold, where a thick gasket is usually located. It could, however, be built into a carburetor mounting bolt, carburetor body or intake manifold with the same effect.
Other-objects, features and advantages of the invention will appear or be pointed out as the description proceeds. 1
BRIEF DESCRIPTION OF THE DRAWING In the drawing, forming apart hereof, in which like reference characters indicate corresponding parts in all the views:
FIG. I is a plan view of the invention constructed so as to fit between the carburetor mounting flange and a carburetor of a conventional automobile;
FIG. 1A is an enlarged sectional view taken on the section line A-A of FIG. 1;
FIG. 2 is a side elevation showing the construction of FIG. I in assembled relation with an automobile carburetor; I v
FIG. 3 is a view similar to FIG. 1 but showing a modified form of the invention; and
FIG. 3A is an enlarged sectional view taken on the line A-A ofFIG. 3.
DESCRIPTION OF PREFERRED EMBODIMENT F IG., 1 is a plan view of the carburetor mounting flange gasket which includes the Jet-edge Whistle. Diameter 1 describes the normal air-flowarea for a single barrel carburetor which would be the same as the diameter of the ordinary gasket used on standard engines. In order to facilitate fabrication, two gaskets, 11 and 12, are cemented'together with knife edges 2 fixed in position in between, so that they span air plenum 3. Screw 4 containing orifice 5 is so placed that the air jet through 5 is split by the keen edge of blade 2.
Since the area described by l is in a state of partial vacuum compared with the outside end of orifice 5, air is drawn through 5 causing an air-jet which is split by blade 2. The air-jet oscillates alternately above and below the blade at a rate determined by the orifice diameter 5, the volume of air passing through 5, the distance 6 from the orifice to the edge of the blade and the dimensions of resonating chamber 14. These values are so arranged that the frequency of oscillation is above 15 kilohertz.
The ultrasonic sound from each Jet-edge Whistle impinges upon the fuel-air mixture passing through 1 and further vaporizes the gasoline there.
' FIG. 2 is-an illustration of how the Jet-Edge device is mounted in an engine. In FIG. 2, 7 is the carburetor, 8 is the carburetor butterfly valve, 9 is the carburetor throat, 10 is the carburetor mounting bolt, 11 and 12 are the gaskets from which the device is made, 4 is the screw through which orifice 5 is drilled.
FIG. 3 shows another form of Jet-Edge Whistle which was successfully operated. In it the knifeedge 2 is served with an airstream from a rectangular orifice 5 of dimension suitable to produce approximately 30 kilohertz of ultrasonic sound.
FIG. 2 shows the ultrasonic device as it is mounted in place inbetween the carburetor and the intake manifold 13. The device could also be madeby some arrangement or other to occupy chamber 9 or 13 or be built into mounting bolt 10.
Resonating chamber 14 is not necessary to the operation of the device, but provides additional sound amplitude and stabilizes the frequency over a wider range of orifice air flow rates.
The construction of jet-edge-resonator systems and their acoustical characteristics are well known and are explained in the Journal of the Acoustical Society of America, Volume 24, No. 3, May, 1952 in an article by W. L. Nyborg; M.D. Burkhard and H. K. Schilling in an article entitled Acoustical Characteristics of Jet-Edge and Jet-Edge-Resonator Systems.
In the preferred embodiment of this invention, the frequency of oscillation is approximately 40 kilohertz. The dimension indicated by the dimension line 6 in' FIG. 1A is 0.24 inch. The diameter of the orifice is 0.05 inch. The length of the orifice 5 is 0.625 inch. The diameter of the resonator 14 is 0.032 inch. The depth of the resonator 14 is approximately 0.073 inch.
The width of the blade 2 from front to back is 0.125
inch. The thickness of the blade 2 is 0.010 inch. The
angle of the blade edge is 13. The air plenum 3 is 0.375 by 0.675 inch. The main body of the device is constructed of two pieces of gasket material, each having a thickness of approximately 0.125 inch, making the combined height of the parts 11 and 12 0.25 inch. The construction shown in FIG. 1 is shaped to fit a 1965 Plymouth six cylinder engine. It will be understood that these figures for the preferred embodiment are given merely by way of illustration.
The preferred embodiments of the invention have been illustrated and described and the invention is defined in the appended claims.
