'- UNITED STATES THOMAS .T MALO, OF HAMMOND, NDIANA DECARBONIZER FOR INTERNAL-COMBUSTION ENGINES Application led .Tune 19,

This invention relatos to a decarbonizer for internal combustion engines and more particularly to a device for supplying moistened air for use in the cylinders ot the engine.

An important object of the invention is the provision in a device of this character of a construction permitting proportional mixture with moistenedair or air which has not been moistened and of gases or vapors withdrawn from the c1ankcase of the engine.

A further object of the invention is to provide a device of this character which may he completely controlled in its operations to regulate the proportions of moistened and unmoistened air to the fumes or vapors withdrawn from the engine crank-case.

A still further object of the invention is to provide a construction permitting the use of a substance such as a penetrating oil in the moistening chamber which will add to the value of the mixture delivered to the cylinders as an explosive compound and which will assist in the removal of carbon deposits from the .Walls of the cylinders and valves o the engine.

A still further object of the invention is the provision of a device of this character Which may be readily and cheaply produced, durable and efficient in service and a general improvernent in the art.

These and other objects l attain by the construction shown in the accompanying drawing, wherein for the purpose of illustrau tion is shown a preferred embodiment of my invention and wherein Figure 1 is a vertical sectional l view through a decarbonizer for internal combustion engines constructed in accordance with my invention;

Figure 2 is a View similar to that of Figure 1 and at right angles thereto;

Figure 3 is a section on the line 3--3 of Figure 1.

Referring now more particularly to the drawing, the numeral 10 designates a cylindrical 'and preferably transparent side wall which, at its ends, engages upper and lower caps 11 and 12 through gaskets 13. vl`he cpper cap preferably has means 14 whereby it may be securedto a support. Depending 1928. Serial No. 286,593.

from the upper cap is a tubular connecting bar 15, the lower end of which is sealed, .as at 16, and is directed through an opening l? formed in the bottom cap 12. A nut 18 engaging the under surface of the bottom capy a tubular boss 22 produced upon the latter at! its center. Retaining nuts 23 lock the pipe in position and the interior of the pipe is threaded, as l at 24,' for the reception of a valve screw 25.,

The boss and pipe are perforated at a piaf rality of points by minute ports 26 controlled by ythis valve and the boss has arising. theren from a spring finger 2T. engaging. the head 28 of the screw valve. vThe tubular connecting bar l5 has a vent 29 opening to the interior of the casing produced by the caps and cylindrical wall at the upper end thereof and beiew the level of liquids hereinafter to be described which are placed in this casing. v

The upper cap 11 has further opening therethrough a lport 30, the wall of which is interiorly threaded, as -at 31, for the reception of a screvir valve 32. This port is refu erably in the form of an inserted valve ody and has its wall perforated at a plurality of points, as indicated at 33, by minute ports which are controlled by the valve screw 32.

@his valve screw is held in adjusted positions in a manner similar to the valve screw 25.

these fittings each having the bores 41 plugged, as indicated at 42, with a plug having a minute port 43 formed therein. Each fitting further has its outer end in the form of a coupling 44 to engage one end of a conduit 45 connecting the fittings` The upper cap may be likewiseprovided with a removable plug through which liquids may be introduced to the casing.

In use of the device, after its installation, it is partially filled with water and a light penetrating oil `which is preferably characterized by the fact that it is readily miseible in water. l

In the operation of the engine, it will be obvio-us that suction will be createdin the upper end of the casing and by this suction, air-Will be. drawn through the port 31 and vents 29 iid vapors will be drawn from the base of the engine through the fittings 38 and 39. Theport 31 has associated therewith a tube 45 by means of which air passing therethrough is discharged into the casing at the lower end thereof. It will, therefore, be obvious that a mixture of moistened air and unmoistened air and vapors drawn from the base of the engine will be drawn through the conduit 37 to the intake manifold. The proportions of these vapors to one another may be very closely regulated by adjustment of the valves 25 and 32, and it will be obvious,

if sufficient air is admitted through these valves, the amount of vapors drawn 4from the base of the engine will be relatively low while, if the amount of air permitted to pass through these valves is reduced, the proportion of the amount of vapors will be increased. It will also be obvious that the proportionate amounts of moistened and unmoistened air may be closely regulated by regulation of the valves 25 and 32, with the result that a perfect balance of these elements is obtainable. The air which enters through the port 3l and tube 45, since it passes upwardly through the water and oil, will agitate the same so that after a short period of operation, these elements will be thoroughly mixed and air passing therethrough will contain moisture derived from both and a certain percentage of both. This air intermingling with the stream arising from the carbureter will serve to break up this air stream and any liquefied particles carried thereby and thoroughly intermingle therewith. The penetrating oil, when delivered to the cylinders, will act upon the carbon deposits therein to soften and loosen the same, so that they may be released by the shock of an explosion land discharged through the exhaust pipe.

It has been found in tests of apparatus of this character that when a proper balance of the mixture is obtained, the low speed control adjusting screw with which most carbureters are now supplied may be completely removed and a perfect idling operation obtained. It has also been found that with a properly regulated mixture, the combustion is so complete that the gases exhausted from the engine are substantially non-poisonous.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself te such specific structure except as hereinafter claimed.
