UNiTEDV STATES PATENT oEFicE ANDREW METZ, or sEwTcxLEY, PENNSYLVANIA YHOT-AIR ATTACHMENT Application led April 25, 1927. Serial No. 186,491;
This invention relates to a hot air attachment for internal combustion engines. is well-known thatthe carbonization on the interior walls of the explosion chambers is a source of much annoyance in keeping the moder walls and creates deficient action, not
portional conversion into power of the fuel,
each of hot alr through a -coupling with the carburetor with the arb mored Figure 4 is a median longitudinal sectional f is inserted in and also racking the mechanism and thereby depleting the equipment.. It is the object of my invention toremove this diiculty.
I carry out my invention by producing at suction stroke fold to the explosion chambers. The injector the mouth of the carburetor and 1s surrounded peripherally by a rotatable sleeve in which a plurality of air holes from the external air are brought into variations of alignment with a sleeve supporting it, said hose being located in the rear of the point of delivery of the injector nozzle so as to carry a jet of hot air`into the carburetor for delivery to the explosion chambers of the engine.
The several features of novelty of my invention will be more fully hereinafter described and the novel features definitely indicated in the appended claim.
In the accompanying drawings igure 1 is a side elevation'partly in section of a decarbonizing system embodying my improvements.
Figure 2 is a side elevation of an injector embodying my improvements.
Figure 3 is a median sectional view of the hose.
view illustrating the detailed construction of the coupling.
Figure 5 is a cross sectional view on a transverse vertical plane of the injector.
igure 6 is a similar section in the plane of an adjusting slot for the sleeve.
eferring now in particular to the drawautomobiles for blowlng cool air over the engine, and 2 represents the flaring mouth of a metallic conduit 3 preferably formed integral with the exhaust manifold 4 of a hydrocarbon engine.- This conduit terminates near the rear wall of the exhaust manifold inl which I provide an outlet 4a with a threaded tip for connection with .a flexible hose 5 preferably of metallicsegments, interconnected in the usual form in metallic hose connections and which is perfectly flexible and may be led by the shortest path to a right angled coupling 6, into which a pipe 7 connected with the carburetor 8 may be united. On the outside of this pipe 7 is sleeved a rotatable cylinder 9 provided with a plurality of air holes l0 and placed in alignment with the corresponding holes l1 in the pipe 7 The cylinder 9 has a circumferential slot' l2into which passes a set screw 13 tapped into the wall of the pipey 7.
he carburetor 8 communicates with the intake manifold 14 and thence with the explosion chambers of the engine. As thus described, when the engine is in operation a draft of hot air is drawn through the pipe 5 and passes in a swift jet through the-injector tube 15, which is threaded at its joint with the coupling Gand is set with its delivery end slightly in advance of the peripheral holes 10 on the sleeve. It will therefore drawn through the holes l0 and delivered to the carburetor to be mingled in the stream,together with hotv air through pipe 5 in ajet, and partially vaporized gasoline delivered thereto by the usual form of fuel supply, and thereby a substantially perfect combustible mixture ma e provided and the mixture is controlled by the adjustment of the sleeve 9.- The mixture supplied by my system effects substantially perfect combustion and avoids any discharge of monoxide gas from the exhaust which is the source of so many fatalities. Moreover, the device reduces carbon to a minimum and 'f thereby prevents overheating of the cylinders and reduces oil consumption, which will result in maintaining the viscosity of the oil and promoting a better action of the motor. All of these results follow from a better mixture and temperature of the gases led into the cylinder with the companion elements of oxygen, hydrogen and nitrogen properly balanced for perfect combustion.
On account of the liquid fuel being fully gasied in the firing chambers, there will be no ungasiied fuel to pass down between the piston and cylinder walls to kill the viscosity of the oil in the crank case. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is An attachment for an internal combustion en ine comprisin a conduit formed with the ex aust manifol of the engine, a flared mouth for said conduit and being arranged in the path of the fan of the cooling system of the engine, a flexible pipe in connection with the rear end of said conduit, a coupling on said flexible pipe, a pipe in communication with the carburetor of the engine and formed with the coupling, a tube threadedly secured to the coupling and extending into the last mentioned pipe centrally thereof, and in ya. manner to be directed toward the carburetor, a sleeve mounted on the last mentioned pipe and being formed with openings arranged so as to register with like openings in the last mentioned pi e, said sleeve being rotatably mounted to a just the position of the openings with respect to each other, and means to retain the s eeve in adjusted ositions and including a headed set screw t readedly secured in the last mentioned pipe and passing through a slot formed in the sleeve.
In testimony whereof I aix mysignature.
