Continuation of application Serial 110,199,349, led October 23, 1917, whioh was a division of application No. 101,457, led June 3, 1916. This application filed May 26, 1919. Serial No. 300,006.

Be it known hat I, PERcIvAL S. Tron, a citizen of the nited States, having residence in the city of Detroit, county of Wayne, and- State of Michigan, have invented certain new and useful Improvements in Methods of Furnishing vExplosive Mixture to Intermal-'Combustion Engines, of which the` leading to theengine intake and referred toy following is a specification, reference being lhad to the accompanying drawings, forming a part thereof.

This application is a continuation of my application, Serial No. 199,349, filed October 23, 1917, and covering subject matter divided out of my application, Serial N o. 101,457, which was filed June 3, 1916.

The purpose of. this invention is to provide an improved method of'furnishing explosive mixture to internal combustion engines. It consists in the method or process described consisting of the several steps and means set out inthe specifications and illustrated in the drawings, as indicated inthe claims;

In the drawings: l i V Figure 1 is an elevation of a portion of an internal combustion engine having a plurality of cylinders, the arts beingr broken away in part on the line, K-A, inl Fig. 2, and shown in sections to illustrate the internal construction. i

Fig. 2 is a detail plan view showing mainly the exhaust manifoldgthe same being broken away in part on the line B-B, on Fig. 1.

a, a, indicate the cylinders o f an internal combustion engine.` b, b, indicate the branches of the pipe containing the passages in the claims as'the .engine intake passage. c is a contracted portion of the atmosphere inlet passage, c, vand leads to the intake manifold. d, isa liquid fuel discharge noz' zle or terminal, offa 'liquid fuel inlet pipe vwhichvis adapted to constitute a spraying nozzle'for s piaying or dispersing the-hydrocarbon'fuel discharged from it, said nozzle being provided for this pur se with a co-axially-situated minor air in et pipe, d. The spraying nozzle which has both the interior a'nd the exterior elements,-that is, the nozzle, d, and the co-axially-situated minor Vair inlet pipe, d,'is positioned with its discharge end extending into the contracted portion, c', of t e main atmosphere inlet passage, c. e is t e exhaust manifold; this is located directly vabove the intake manifold the current of issuing vapor.

in the construction shown. f is a casting forming a chamber closed at its upper end and open at its lower end, and said casting fitting into the intake manifold, b, so that its interior is open tothe interior of said manifold, and is axially in line with the contracted portion, c, of the atmosphere inlet, c. Thecasting, f, extends upward into the exhaust manifold, e, and is provided with 'i f, and is caused to strike against the interior surface of said casting and the ribs, f2, in4 a very finely divided form or mist, so that it is immediately vaporized and the particles 3()I thus do not come into a spheroidal state.

The vapor expands'and flows into the manifold, b, b, and is mixed with lthe incoming air, and gives up its latent heat in part to the air,\so that itis condensed into a mist 315 which remains suspended in the air and is readily re-evaporated in the cylinders.

Because the amount of liquid discharged through the nozzle, d, is proportional to the quantlty of air passing, and because the llquid is projected into the chamber inclosed by the casting, f, and is immediately vaporized therein, the amount of vapor issuing from the interior of said casting in the pass# ing air will be proportional to suchair, so that the air will be'heated to about the same degree under all conditions of working of the engine.

The insensible heat of the issuing vapor is largely used to heat the spraying liquid en- 100 terme the chamber in the cas-ting, f,

against I claim 1. The method of furnishing 'an explosive mixture to an internal combustion engine 105 -whichconsists in first producing by the suction of the engine africh mixture of liquid fuel and air at substantially normal temperature byaspiration; and next heatingV such rich mixture to the vaporizing point 110 of the liquid fuel particles, and linally, thoroughly intermixing suchvaporized mixture with an additional quantity of air at a lower temperature.

2. The method of supplying an explosive mixture to an internal combustion engine, which consists in drawing in by the suction of the engine a charge oi hydrocarbon fuel and a limited charge of air at substantially normal temperature in such juxtaposition thereto as to cause intermixture of the hydrocarbon fuel and subh limited air supply; next, continuing the suction of the engine upon the rich mixture, and thereby vcausing it to be injected into a chamber heated above the vaporizing point of the hydrocarbon;

- next, engaging it on its emergence from the hea-ted chamber in and by an air current also drawn in by thesuction of the engine at a lower temperature.

3. The method oi supplying an explosive hydrocarbon mixture to an internal combustion engine, which consists in drawing in by the suction of the engine, a liquid hydrocarbon supply, and simultaneously and contiguously by the same suction drawing in a limited air supply at substantially normal temperaturefor mixture with said hydrocarbon liquid supply; next, causing said mixture to be injected, by the momentum of the in-drawing movement into a chamber heated above the vaporizing point of the hydrocarbon, and to be discharged from said chamber by the same path by which it entered into a greater air current drawn in by the suction of the engine, Jfor admixture with the air thereof. p

In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 16th day of May, 1919.
