Application September 28, 1949, Serial No. 118,427

This invention relates to a carbon eliminator, and more particularly, has reference to a device of this type adapted to eliminate the carbon in gasoline engines. V

The injurious efiect of carbon upon gasoline engines is of course Well known, and need not be dwelt upon at length herein. As is well known, engines free or substantially free of carbon operate with considerably less friction, and as a result havemaximum power accompanied by a 'clear and distinct saving in fuel.

an engine below the carburetor; spaced partitions in said container and respectively notched at opposite ends to cause air flowing through the container to move through a tortuous path; and

' cylindrical screen containers mounted upon and extending between said partitions and projecting beyond opposite sides of said partitions,said screen containers each being filled with chemicals incrystal form adapted to attack carbon by causing a chemical reaction creating a gas which will soattack-the carbon.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes maybe made in the construction and arrangementof parts without departing from the spirit of the invention as claimed. 7

Referring to the drawings: Fig. 1 is a perspective view, portions being broken away of a carbon eliminator formed in accordance with the invention.

Fig. 2.is a side elevationalview showing the partitions and the chemical carryingcontainers supported thereby. j Fig. 3 is an end elevational view of said partitions and chemical containers. e

Referring to the drawings in detail, 5 is a metal box here shown as rectangular in form, but which can in accordance with the invention take other shapes. The box 5 is formed at one 1 Claim. (Cl. 123-498) as clearly shown from Fig. 1.

2. end with a plurality of air intake openings 6, through which air moves into the box in the direction of the arrows illustrated in Fi 1.

The box is provided with a cover I which once attached to the box is preferably secured thereto in a manner toseal the box tightly against the admission of air except through the air intake openings; The lid 1 can be soldered or otherwise rigidly secured in a sealing relationship to the box.

At the other end of the box, said box is provided with a fitting or coupling 8 whereby there can be attached thereto a copper tube 9 or the like, leading to the intake manifold, not shown, of a gasoline engine, immediately below the carbureter.

The fitting 8 represents an outlet opening for the box, disposed at the opposite end thereof from the air intake openings 6, and disposed adjacent the top of the box, as distinguished from the air intake openings 6, which are disposed near the bottom of the box.

Within the box, there are mounted spaced partitions l0 and II that are mounted in upright position within the box, one of these partitions being disposed near one end of the box and the other partition being disposed near the other end, The partition l0 engages the box along all its edges, and the bottom edge of the partition I0 is formed with. a notched indentation I2. Thus, since all the edges of the partition l0 tightly engage the side walls, bottom, and top of the box, air can move past the partition l0 only through the aperture l2.

The partition II is of approximately the same shape as the partition l0, and is identical to said partition with the exception that the partition I l is formed with a notch [3 at the topof the partition as distinguished from the partition it] which has its notch at the bottom.

The partitions are formed with aligned openings M, in suitable number, and extending through these openings between the partitions, and projecting beyond each of the partitions as best shown in Fig. 2, are the cylindrical wire mesh containers l5 each of which is filled with chemicals [6 in crystal form, which chemicals will be described in more details hereinafter. These chemicals are of such a nature as to set up a chemical reaction when air passes therethrough, which chemical reaction sets up a as which is drawn with the air into the combustion chambers and which, after beingexploded, operates to attack and eliminate carbon formation upon the engine parts.

As may be noted from Fig. 3, the cylindrical screen containers l5 can be closed at the ends simply by folding over the flaps ll defined at said ends of the container, thus to close the screen containers completely for the purpose of retaining the chemicals 16 therein.

The screen containers l5 preferably extend practically from end wall to end wall of the box 5, so as to have. maximum effect upon air moving in the tortuous path through thebox.

Considering the passage of said air, it may be noted that as a suction is set up in the intake manifold, air will be drawn through the air intake openings 6, and will be caused to move upwardly in end chamber l8 defined between the partition H and the adjacent end wall of the boxfi. 'This air moving upwardly through-.t-he-end chamber 18, is caused to move past and through the pro-- jecting end portions of the wire meshcontainer l1, thus to cause the aforementioned chemical reaction to be instituted.

Thereafter, I the air passes through the :note I3 at the top 'of the partition H, into a middle chamber 19, and moves downwardly'through this '--1 i1iddle' chamber, through medial portions of the chmical containers [5, so as to be further acted upon by the chemicals in said containers.

Thereafterjthe air moves out of the middle to move through the outlet opening 8 by the suc 'tion' action mentioned "above, and then through "the coppertubing '9 into the intake manifold.

After mixture withthe'engine fuel, and explosion,

said gases attack'the'car'bon that otherwise would tend to form upontheengine parts.

With respect to the chemicals which I have foundadvantageousfor the purpose'of obtaining the desired results, I-pro'vide amixture of chemicals .in' crystallized form as follows:

Parts 5 NHiCl--Am1nonium chloride 3 CaCl22H2Oj-Calcium' chloride l 3 C iHsOeTartaric acid 2 Zn'Cl2Zinc "chloride l. 1. "Sodium chloride; l 1

The gas which occurs through the chemical reactionprcviouslymentioned is not injurious in any way to metal, although it efficiently attacks and in eifect eliminates the carbon tending to form upon engine parts. and destroys the greater percentage'of the carbon monoxide gas which would otherwise be present.

This'gas further-attacks "Byreason of=a carbon-eliminator constructed in ccordance with the invention, and mounted in-a vehicle adjacent theengine and in the position stated, the engine will be allowed to run substantially free of carbon, thus to bemore flexible in operation and to operate with less friction, -with'a resultant increase in'po-wer ac- *companied by a saving infuel.

It is pertinent toconsider further exactly I how the chemicalsoperate to eliminate carbondeposits that otherwise would tend to 'form upon metal parts of the engine. In this connection, ammonium chloride,- zinc chloride, tartar-icaoid,

4 and sodium chloride, with a small amount of moisture, will remove carbon from metal. Calcium chloride furnishes the necessary moisture to assist in the creation of gas, the generation of the gas further being eiiected by the circulation of air around the foraminous tubes. The gas so generated is drawn into the intake manifold with said circulating air, by suction set up in the intake manifold by operation of the engine. This .gasisfdrawnunto the intake'manifold below the carburetor, that'is, beyondthe outlet side of the carburetor. It feeds, along with the fuel-air mixture that enters the intake manifold from the carburetor, to the engine cylinders and during the explosion of the fuel-air mixture and after said e'xplosio'n, the chemical analysis of the generated .gasdoes not change.

In this regard, if it were tochange it would 'not have any effect upon the carbon. As to the eilect of the gaseous compound upon the carbon, it should be noted that it does notlchange thecarbon'to a gas, but only loosens the carbon deposits from the metal parts, whereupon the loosened carbon particles are blown out through the exhaust.

Whatis claimed is:
