Application filed February 9, 1929. Serial No. 338.78%.

My invention relates to manifolds and more specifically to devices of the class designed for separating out the heavier hydrocarbons and the water from the fuel mixture before it enters the cylinders of the engine.

It is a well-known fact that nearly all of the gasoline at present on the market contains a relatively high proportion of heavy hydrocarbons which do not vaporize readily and which therefore will not be utilized in the engine. Not only is the heating value of these hydrocarbons wasted but they are deposited on spark plugs, valves and cylinder walls in the form of carbon which causes considerable trouble in the operation of the engines. Water in the form of minute globules also occurs suspended in the gasoline and the presence of this water is objectionable as long as it is in liquid form. My invention therefore has for its main object the provision of a device for vaporizing both the heavier hydrocarbons and the water found in gasoline and delivering them to the cylinders of the engine in volatile form.

:5 It is my object to separatethe heavier hydrocarbons and the water from the fuel mixture in its passage to the cylinders, to con duct these liquids through the exhaust manifold to thus vaporize them and finally to in- ;0 troduce them into the stream of fuel mixture in vaporized form.

Another of my objects is the provision of a combined impeller and propeller which utilizes the power of the stream of flowing 5 fuel mixture and imparting a whirling motion to the fuel mixture to separate out the heavier liquid particles by centrifugal action.

An important object of my invention is the provision of means for volatilizing the heavler hydrocrabons and water in the motor fuel and for then cooling these vapors before they are delivered to the cylinders of the motor.

Still another object which I have in view is the provision of a device forseparating the i heavier hydrocarbons and water from the motor fuel and for imparting a whirling motion to the fuel mixture so as to deliver a homogeneous fuel mixture to all of the cylinders.

Having in View these objects and others which will bepointed out in the following description, I will now refer to the drawing, in which* V Figure 1 is: a view in perspective of my manifold and its connections with the ex- 5 haust manifold and the intake manifold of the engine.

Figure 2 is a sectional view showing particularly the combined impeller and propeller and showing also the return passage for the liquidparticles through the exhaust manifold and back into the current of fuel mixture.

Figureg'is a'plan view of the lower'portion of theintake as it would appear if the 06' upperv portionshown in Figure 2 were re moved. p I

Figure 4 is a view in perspective of the combined impeller and propeller. j

The intake 10 and 11 is connected at the extremity 12 to the carburetorand at the opposite extremity 13 to the intake manifold 14. The fuel mixture passing from the carburetor throughthe portions 10 and 11 of the intake v are thus delivered'to the intake manifold 14 where it is distributed tothe cylinders.

The portions 10 and 11 of the intake are separable as best shown in Figures 1 and 2, to'permit the insertion of the combined impeller and propeller. The portion 10 is provided with an enlarged casing in cylindrical form and theportion 11 has an annular flange seating against the casing'of the portion 10, the two being held together by means of, screws or bolts or the like. The bottom of the casing is provided withasump 15 for receiving liquid particles thrown off by the impeller 16. As shown. in Figure 3, this sump is in spiral form and it increases in width toward its mouth. t also increases in depth toward the mouthso that there will be a gravity flow of liquid toward the mouth. The

mouth of the sump is connected by means of the tube 1'? with the intake at 18, the tube 17 passing into, through and out of the exhaust manifold 19. It will be apparent that these liquid particles under the intense heat of the exhaust manifold will be vaporized before they are returned to the intake. 7 The intake is further provided with a Venturi constric- 100.

tion 20 just beyond the outlet 18 of the pipe 17.

In mounting my combined propeller and impeller in the intake 10, I secure a cone-like base 21 within the flared portion of the intake. The base 21 functions to divide the current and to force the annular stream through the impeller 16, the impeller being so designed and positioned that it is practically impossible for any of the fuel mixture to pass through to the portion 11 of the intake without passing through between the blades of the impeller 16. The impeller 16 consists of numerous radial blades and it is designed to be rotated at a high speed so as to discharge all of the heavier particles from the fuel mixture. In order to give this impeller the necessary high speed for centrifugally separating the portions of the fuel mixture, there is attached thereto and integral therewith a propeller 22 having a plurality of radial blades which are inclined so that the current of fuel mixture passing through between them causes the rotation of the combined impeller and propeller.

During the operation of the engine the stream of fuel mixture from the carburetor to the cylinders is constant. As above explained the heavier hydrocarbons and water are removed from the fuel mixture and vaporized after which they are returned to the stream of fuel mixture. The vaporization of the heavy hydrocarbons and water is accomplished by heat but the vapors thus produced are cooled to a certain extent before they are reintroduced intothe fuel mixture.

through the propeller. In passing through the propeller 22 the stream of fuel mixture is given a whirling motion which thoroughly homogenizes the fuel mixture so that substantially equal charges of fuel are delivered to the various cylinders, this being essential for the smooth running of the motor. 1

Having thus described my invention in such full, clear, and exact terms that its construction and operation will be readily understood by others skilled in the art to which it pertains, what I claim as new and desire to secure by Letters Patent of the United States 1s: v

A gaseous fuel mixer and separator adapted to be inserted between the intake manifold and carburetor of an internal combustion engine having a passageway for conducting a stream of fuel to the cylinders of the engine comprising arotating fan within the passageway for centrifugally separating moisture and heavy hydrocarbons from the fuel mixture, and a by-pass for said passageway, said by-pass passlng through a heated portion of the exhaust manifold and adapted to receive the moisture and hydrocarbons separated from the fuel mixture, to conduct the separated moisture and hydrocarbons through volatilizing temperatures and to lead the separated moisture and hydrocarbons after volatilization back into the stream of fuel mixture, and a venturi in the passage- Way at the outlet extremity of said bypass.

In testimony whereof I affix my signature.

VICTOR VOSTREZ.
