DAVID r. DAvms, or enormi, wrscon SIN, AssrGNoa 4're J. I. Casalini-Esame A MACHINE COMPANY, F RACINE, WISCONSIN, A CORPORATION;
vasiatica.
abplieauon med october To' all whom it may dance-m.'
e it known that I, DAVID citizen of the United States, residing at Racine, in thecounty of Racine and State of Wisconsin, have invented certain new and useful Improvements in Internal-Combustin Engines, of which the following is a P. DAVIEs, a
specification.
`ducted My invention relates to improvements in internal combustion engines, my object being to obtain a high degree o-f fuel Vaporization by maintaining constantly heated surfaces with which the fuel particles come in contact, which heated' surfaces are so arrangedas'to give the fuel mixture high velocity in yits travel, and thus breakup or dissipate the heavier fuel particlesl and reduce the mixture to thorough gaseous condition, all as will be hereinafter more particularly pointed out. l
ln, 'the accompanying drawing, -which forms a part hereof, Figure 1 is a horizontal sectional view through an engine manifold, vthe position of the cylinder and inlet and exhaust valves being yindicated by dotted lines, and Fig. 2 is a vertical sectional view through the manifold showing the mixture inlet and exhaust outlet.
In said drawing, the portion marked 5 indicates the fuel mixture inlet, which is connected to a carbureter, as at 6, in a wellv ilmown manner, said mlxture vinlet leading' to and connectingk with an enlarged mixing chamber, 7, for expansion of the mixture before the same passes in opposite directions through the Venturi tubes, 8 and 9, and con the engine, which, as will be understood,
lcommunicate with the engine cylinders, 12, 13, 14: and 15. The exhaust outlet, 16, communicates with 'and leads from the cylinders 13, 14 to the jacket, fold, and similar exhaust outlets, 19, 20, communicate ,with and lead from the end cylinders 12, 15 to said jacket 18, from which latter the gases are discharged through the main exhaust pipe, 21. In said jacket-18 I prefer'to form channels, 22, 23, to take care of the difference 1n expansion between said jacket and the tubes 8 and 9.`
The fuel .and air furnished by the carbureter pass through the mixture inlet 5 and into chamber 7, which latter is maintained at high temperature by theY exhaust gases discharging from the engine through exthereby to the inlets, 10 and l1, of i 18, of the exhaust maniiNTEnNAL-coMBUsTroN ENGINE 1, 191e. serial No. 327,803.

the same passes throughthe .throats of the ,i
the result being a very particles are thrown to the outer radius of` while the elbows with yconsiderable force, the lighter particles and gasified fuel around the elbows 8- and 9 of the smaller radius, and through inlets 10, 11. The' heavier fuel particles, however, as indicated, strike the .bends 8, 9', at considerable'velocity and become broken up in liner particles, and as the surfaces of the bends are kept hot by the impinging exhaust gases which constantly pass throughthe exhaust elbows, 19 and 20, intojacket 18, these liner particles become gasied at that point. g
In the manner described. the exhaust gases from the engine constantly heat the vVenturi tubes, and -also the walls'of the expansion pass point, which materially The fuel and,y air thus chamber 7 so that the fuel mixture from the comprising the innerv the fuel particles can remain in contact with heated surfaces the more thorough vaporization will take place, and, as fuel particles are always heavier than'the air with which they are mixed, when passin at high velocity, they. l be. thrownout toward the larger radius of the bends by centrifugal force, and thus be subjected to the around the bendsv l bustion engine, of a manifold comprising a heat from the exhaust elbows 19', 20. in the manner stated.
I am aware that the Venturi tube prin ciple has been proposed in the development of fuel vaporize-rs, but my improvement, comprising an enlarged expansion chamber having such tubes communicating therewith for conducting the vaporized fuel therefrom at high velocity, and so arranged that the exhaust gases from cylinders 13,- 14, impinge directlyupon said chamber, and those from cylinders 12, 15, impinge directly upon the elbows of such tubes, has proven in extensive practice to be a highly efficient arrangement for quickly and thoroughly Vaporizing such fuel as kerosene and the like. and reducing the particles of such fuel mixtures to a thoroughly gasified condition. It is essental to provide the channels 22, 23, in jacket 18 to take care of the expansion and contraction of said jacket during the varying changes of temperature created by the fuel circulating therein and the intense heat of 4tubes 9, as will be understood.
I claim as my invention: 1. The combination, with an internal comjacket having channels integrally formed in its Walls to permit expansion and contraction thereof, an expansion chamber therein for the reception of a fuel mixture, and Venturi tubes communicating with said chamber and extending laterally from each side thereof, said tubes terminating in curved formation and communicating with said engine.
2. The combination, with an internal combustion engine, of a manifold having means at its middle and two end portions for the reception of exhaust gases from said engine, said manifold embodying channels at each side of its middle portion for permitting expansion and contraction of its Walls and a manifold in said first mentioned manifold having an expansion chamber and tubes leading therefrom to said engine, said tubes gradually enlarging and curving, for the vaporization and discharge of a fuel mixture into said engine.
3. The combination. with an internal com bustion engine. of an exhaust manifold having channels in its Walls, and a fuel Vaporizing and inlet manifold in' said exhaust manifold comprising anenlarged mixing chamber and Venturi tubes leading therefrom and communicating with said engine, said tubes being curved so that the gas from said exhaust manifold will impinge upon the outer curved portion thereof.
In testimony whereof I afix my signature.
