To all whomz't may concern:

Be it known that I JOHN A. SEooR, a citizen of the United tates, residing at Laporte, in the county of Laporte and State of Indiana, have invented a certain new and useful Improvement in Processes of Preparing an Explosive Mixture for Internal-- Combustion Engines, of which the following is a specification.

My invention relates to a process of producing a mixture of fuel and air for use in an internal combustion engine. In such engine are means for the incorporation of a mixture of the fuel ingredients and a passage for their subsequent transmission to the engine or cylinder. The mixture may consist of air and any kind of fuel, or air, fuel and water and the particular mixture with which I am concerned, is air, oil and water. These ingredients are commonly united by some apparatus in the process of introduction so as to produce in effect a mixture consisting of air and atomized oil and water. As these mixed ingredients pass along toward the cylinder, experience shows that a certain quantity of the fuel, oil or water or both tends to be separated out of the stream of the mixture by the impingement of the current on the walls of the passageway or valves or controlling device which may be placed therein. My invention relates especially to compensating for this difficulty and it is illustrated by the particular mechanism which may be used to carry out my process. Of course, various other sorts of mechanisms could be devised,

l either automatically or hand controlled.

The particular illustration which I have se lected is that of an engine adaptedto be supplied with a mixture of oil, air and water and where the difiiculties of separating out the liquids from the mixture current are due to the throttle valve.

In illustrating this:

Figure l is a cross section through the carburetor with a first reatomizing device;

Figure 2 is a detail cross section of the passage pipe with a modified form of atonh izing device; l

Figure 3 is a detail of an extension of the passageway and showing a reatomizer at the intake valve.

The device of Figure 3 is intended to be used .in connection with the device of Fig-` ure l and the device of Figure 2; or 'any other atomizing device could be substituted for either or' both of the atomizing devices shown in Figures l and 3, but a single reatomizing device of any kind could be used either near the throttle valve or near the intake valve or at any point between them. 1

and water nozzles and the engine, adapted to be controlled vby means of the lever'A.9 and link A10 from governor or other throttle controlled mechanism not here specifically illustrated.

B is an atomizing or re-atomzing sleeve inserted in the passage immediately below the butterfly. This sleeve takes the form of a modified Venturi tube. The modification consists in that the tube is cut away on the up-stream side of the point of greatest contraction so as to provide a sharp annular knife edge B1 with a downwardly and outwardly extending curved channel or reservoir B2, thewall of the Venturi tube being sloped upwardly from the bottom of the reservoir as at B3 to nally merge into the normal Venturi contour. In order to illustrate the slight modification the :normal Venturi contour is shown in dotted lines asiat B4.

The venturi B is integral with the flange C, and this flange may be inserted between the carburetor and the engine, and the carburetor web will be protected against breaking by i'iller blocks C1, or washers, which.

take the strain of the bolts, and are the same A 100 rangement gives a final atomization land mixing j ust as the mixture enters the engine, and thus we have a peculiarly Ihomogeneous mixture which leads to peculiarly satisfactory operating results.v

y Thus I have disposed two Venturi tube atomizers between the throttle valve and the intake. Y

Referring to the device of Figure 2, the passageway A1 isV provided with an interior trough F which is arranged about the side ofthe passageway and is provided with the edge G. Under certain conditions such a device might be operated more or lesseifectively' to atomize the liquid by collectlng 1t 4as it flows down the side and then exposing it to the outer knife like edge of the trough which lies in the path of the moving cur# rentv of air or mixture. This is only d one to suggest the different forms of atomizer which might be employed.

The use and operation of my invention are as follows The liquid fuel and the water, although,

of course, the water might be dispensed with, are fed into the carbureting pipes or chamber in the usual manner, being induced by the rapidly flowing air current caused by the operation of the engine. The means not illustrated in detail, are provided, of course, for controlling the flow of both the liquid fuel and water. It will be noted that the water and fuel nozzles ldischarge into the carbu-4 retor at different points wherethe pressures are different'thus, of course, resulting, in

`automatic differences at the nozzle which being heavier than the air, it will be separated out by inertia and the air will go on carrying probably a lean and unsatisfactory mixture and the liquid will rundown the walls ofthe tube. This liquid will caught by the ledge in the venturi and the little annular reservoir formed 'by that-ledge will be filled up with liquid, and as more liquid comes down, it will overflow the sharp knife edge. Asit overfiows, it comes into the direct path of the yair and it will be suddenly torn apart and atomized by such air.'

Experience shows that the diameter of this modified Venturi tube for the lower reatomizer must'be a little larger to get the same capacity, than the diameter of a norf mal venturi. This is probably caused by the fact that the effective diameter ofthe venturi is decreased by the thin film of oil overiiowing the ledge all the way around, before this thin film of oil has time to be broken up and carried away as part of the atomizing mixture.
