- Application md Marchl 11, 1924. serial No. 698,418.

This invention relates 3 to a inethod i and apparatus for producing-.gaseous fuel and its main object is to .provide by a system ofksimplei devices, .an .eilicient and economical method` of producing avigaseousA mixture adapted for use ask an illuminant or a fuel.

A further `object of the invention is to roduetionof a gaseous mixture ofthe agovedescribed character the exhaust gases ofv an internal "combustion engine, and still anotherobject resides in providing in a system of producing fuel gas,

an improved manner of charging a gaseous motive Huid with volatilized hydrocarbons derived from a supplyof ay volatile. hydrocarbonaceous liquid. 1 ,4

Our invention broadly comprehends'the provision of a chamber in which -a hydrocarbonaceous liquid suchas gasolene,is intimately ntermixed 'in vapor form with the exhaust gases of an internal combustion engine, and as such, it is particularly adapted for use in connection with a-power driven vehicle of `the internal combustion engine type. i,

An embodiment of our invention has been illustrated in the accompanyingI drawings, in the several views of which like parts are similarly designated and in which A Figure l represents a diagrammatic, partially sectional elevation of the system of co-operative devices comprised in the inven tion;

Figure 2, a similar elevation Ashowing a modification in the arrangementof the parts of the system;

Flgure 3, an enlarged sectional elevation of the mixing chamber of the system;

Figure 4 is a detailed vertical longitudinal sectional view of one of the check valves comprised in the system and with a spark plug 6 and with a relief cock 7 vfor the escape of fuel gas compressed by movement of the respectivepiston.v

The reference character 8 designates 'a tank for the supply liquid fuel, such as those used in connection of a hydrocarbonaceousvv with automobiles of the internal combustion. engine type for example,'oils such' as gasoline or kerosene, ber in which the'exhaus't or'combustion gases from the .engine are charged with hydrocarbons derived from the liquid inthe reservoir 8, 1() designates a reservoir in" which the oil gas produced in the gasifying chamber may be stored for future use, and 12 is a` reservoir in 'which the exhaust gases ofv the `engine accumulate beforethey pass to the gasifying chamber. f

In the arrangement shown in Figure 1 of the drawings, one of the relief cocks of the engine has been removed and the openin of the pistonchamber in which it 'was attalied is by means of a pipe 13 connected -with an intake-opening of the reservoirl2. A cheek valve 14 in the pipe 13 prevents the return HOW of gases from the reservoir 12. A pipe 15 connected with an outlet opening of the reservoir extends into the gasifying chamber 9 with its open end in opposed pipe 17 is connected with the, source of 9 1s a' mixing or -gasifying chamliquid fuel supply represented by the tank 8. f

A preure regulating valve' 18 is interposed between the reservoir 12 and the gasifying chamber in the pipe 15, to equalize the fpressure at which the exhaust gasesenten the gasiying chamber, an equalizing Avalve 19 is for the 'same purpose interposed betweenthe tank 8 and the gasifying chamber in the pipe 17 and a cheek valve 20 connected in the same pipe prevents the return flow of iuid from the gasifying chamber to the gaso-y line tank. a r In Figures 1 and 2, the nozzle has been shown diagrammaticallyin a positionl opposite to the open end of the pipe-which'com nects with the reservoir 12, but in Figure 3 is illustrated a preferred arrangement of thel nozzle and the pipe which is conductive to promoting and expediting vaporization of the hydrocarbonaceous liquid-and its intermixture with the exhaust gases.

.The nozzle in the construction shown in Figure 3, is constituted by the end of thel The end portion of the pipe extending v Y into the mixing chamber, is preferably connected with the body portion of the same through the medium of an elbow 24 provided with a stuffino' box 25 through Whiehthe stem 22 .passes for its connection with a hand lever, pedal or other device to eifectits longitudinal movement for the adjustment of thavalve 21 relative to the orifice of the nozzle.- y The valve has exteriorly of the nozzle a disk-shaped eollar26 upon which the liquid i; gases enterlng fuelA discharged from the pipe 17 impinges -and which causes it to be finely divided and diffused into .the hot exhaust or combustion the gasifying chamber through the pipe 15. The discharge end of a conduit 15 forms a tubular outlet which extends through onewall of the mixing. chamber and terminates short of the opposite wall through which the nozzle extends. A

' .-The nozzle which is of a diameter less than etw -across the periphery of 4the baille disk or that ofthe tubular outletprojccts into the same, and the deiieeting or baille disk 26 which is arranged in the path of the discharge from the nozzle is of a diameter less than -that of the interior of the tubular outlet and it partially constricts the same and it forms' an annular space'or passage between its eriphery and the walls of the tubular The exhaust gases pass over or member in an annular stream against which the gasoline'from the nozzle is sprayed. the outlet and the baffle are heated by the exhaust' gases the gasoline is in the form of a fine spray or vapor when 4it comminglcs with the exhaust gases and as it leaves the outlet pipe into the mixing chamber it is in gaseous form and thoroughly mixes with the exhaust gases in the mixing chamber.

The gasifying chamber, has an outlet-- opening which by means of a pipe 37 isconnected with the reservoir 10, a check valve 40 in the pipe prevents the return flow of the oil gas t'o the mixing chamber, and a valvecontrolled pipe 29 connected with an outlet of the reservoir 10 is provided .to conduct the oil gasto the .burners of a stove, lamp or other similar eontrivance.

-It is preferred'that in the operation of the system, the gasoline or other volatile liquid beforced from the tank and into the gasifying chamberunder mechanical pressure. In motor vehicles equipped with the Figure l.

so-called vacuum system, this pressure 'is' automatically produced inthe operation of the engine, but 1t may be obtained by the use of a pump or other similar compliance Yas indicated at 30 in Figure 2,'or it may be supplied by connecting the upper portion of the tanlrfvith the combustion s ace. of another piston chamber of `the englne'through the medium of a pipe 31 as shown in The last mentioned method 'of supplying the pressure to the gasoline has the added advantage of adding to the carbonaceous fuel by any unconsumed or uncombusted fuel which maybe left in the, combustion chamber through imperfect combustion.

In the operation of the system, the lgasoline forcibly introduced into the gasifying chamber is brought into violent contact with the hot exhaust gases which enter the chamber likewise under pressure.- ."lheim`v pact ofthe two fluids causes the liquid to be finelydivided and diffused in thehot gases discharged fromv the enginewith'the result that it iscompletely-.vaporizd*and in that condition isintimatelyfand thor'- oughly intermixedivith th'evexhaust gases.l

The result of the mixture thus producedis a Agaseous fuel which' is useful 'as veither 'av fuel or an illuminant. J

By the use of a valve controlling the' discharge of-liquid from the -nozzle,-as shown' at 32 in Figures 1 and 2, or as illustrated in detail in Figure 3, the richness ofthe mix# ture maybe regulated according to varying conditions and requirements, and y:it `vill be readily apparent that although the reser'

voirs

12 and 10 are advantageous and'under certain circumstances indispensable, the 'opcrative condition of the system is not detrimentally impaired by placingthe mixing chamber in direct connectionwith theI exhaust opening of the engine or byconducting the mixture produced in the chamber v9 directly to the burners.

It will furthermore be understood that vif f so desired; the exhaust gases may 'beobtained by" a suitable valve controlled 'con-v ncction with the exhaust-manifold-'of the tank 8 before the mixture passesrto the reservoir l0. The outlet of the primary gasifying chamber is in this construction, provided with a'pipe 33 which extends into a secondary gasifying chamber 34 in axial. alinement with a nozzle yfiat the end of an extension 36 ofthe gasoline feed -pipe 17 and an outlet of the secondary mixing chamber lis connected to the storage tank by means of a pipe 37, manuallyl adjusted valves 38 andv 39 in the. pipes control .the ow of gases and liquid to the secondary chamber and a heck valve 40 prevents the returnflow vof gases from the reservoir 10 as before. v

While our process and apparatus as above described, are particularly adapted for the production of gas suitable for use as a fuel in heater or stoves and other similar appliances, or as an illuminant in lamps, it will be evident that under favorable conditions it may also be employed as'an explosion mixturefor use in the operation of an 'internal combustion engine.
