DIL-E'URIFYING APPARATUS FOR HYDROCARBON ENGINES.
Application filed January 29 1926. ,Scrial No. 88,255.
The-present invention relates to improvements in 'oil purifyln'g apparatus for internal combustion engines, and more particularly to means for aerating the oil inits 55 passage from the crank caseor main reservoir to the refining device in which the air and volatile impurities are separated out,
the oil being returned to the oiling system. The ir is preferably commingled with the oil at the lower endor inlet of the conduit through which the oil is conveyed to the refiner. The air, preferably heated, lightens the rising column ofoil, causing it to flow more readily. Furthermore by causing the air to travel with the oil it is made to absorb the volatile impurities, such as gasoline and water, and greatly aid therefiner in separating these impurities from the oil. The invention is illustrated in, the accompanying drawing, in-which Figure '1 is aside elevation of a hydrocarhon engine with apparatus embodying the" present invention applied;
Figure 2 is a sectional viewot the aerat-- ing device;
4 Figure 3 is a section on the line 3-3 of Figure 2, and 1 Figure 4 is a sectional view similar to Figure -2, showing'a modification.
Referring to the drawing A indicates the engine, 10 the exhaust manifold, 11 the intake manifold, 12 the throttle valve, 1?) the carburetor, and 1.4-. the crank case, the normal oil level being indicated by the dotted line 15.
' The refiner B may be of the typo-illustrated in Figures 1 to 4 inclusive of my Patent No. 1,359,453, dated November 16, 1920, or of any other form in which a partial vacuum is used to draw the oil to the refiner and to assist in-vaporizing the volatile impurities. The operationof the refiner is fully described in the before-mentioned patent. In the drawing, 16 indicates the conduit connecting the refiner with the intake manifold above the throttle to produce a partial vacuum and to convey the impurities removed. from the oil to the engine, 17 indicates the condi it'which returns the puri fied oil to the oiling system, and 18 indicates the conduit through which the oil is con-1 veyed from the crank case or reservoir to the refiner;
As shown in the drawinga valve casing- 19 is connected to the pipe/18 and a pipe 18 connected to the lower end of the valve oil and thus aids in refining theoil.
casing extends into the oil, represented at '15 in the lower part of the crank case or reser' voir 14. 'The valve casing has a port 20 through which air enters'and passes down through an inner tube 21 to be discha rged near the lower end of the pipe 21 which is slightly above the bottom of the pipe 18*. The admission of air is controiled by a suitablevalve 22 and the lower end of the tube 5 21 is preferably below the normal 'level of the oil in the reservoir, although-not necessarily so. w
The suction in pipe 18 draws oil from the crank case and also draws more or less air from the lower end of the pipe or tube 21., which air in bubbles rises-with the oil and flows into the refining device B through ,pipe 18. Openings 23 in the body of the valve 19 permit the air and oil to pass from the pipe 18". to the pipe 18. Que etiect of the air is to lighten the column of oil and cause it to flow more freely into the refining chamber; A second advantage of this arrangement is that the air by reason of its intimate mixture with the oil absorbs some of the gasoline, water or other volatile dil-uents of thev This eli'eet is enhanced by heating the oil in its passage to the refining chamber, as may be done by tliecoil 18 encircling the exhaust manifold 10 or in any other suitable manner,
The amount of air required to aerate the oil is small and the valve 22 is therefore in the nature of a needle valve regulated by a screw 22, In Figures 1 and 2 I have shown means for heating the air consisting of a pipe 24 coiled about-the exhaust manifold and leading to the inlet 20. While it is preferable to heat the air to cause it to absorb a greater quantity of the volatile impurities in the oil it is-not essential that it be heated and hence I have shown in Figure 4 an inlet 20 for air at ordinary temperature. This inlet is preferably in the lower side of the casing to prevent it from being clogged with dirt.
The operation of the apparatus willbe obvious from the foregoing description. The partial vacuumin the intake manifold when the engine is running creates a partial vacuum in the refiner B which causes the oil to be sucked up from the crank case or any suitable reservoir through pipes 18, 18 and discharged into the retiner.- The suction in pipe 18 will draw air from pipe 24: and cause it to mingle with the oil. This Will mixture of the air andoil will cause the'air to absorb volatile impurities from the oil,
especially if the air be preheated. The air will be separated from the oil in the refiner and will be drawn into the intake through through zpipe 17. The quantity ofair admitted should be limited by the valve 22 to an amountwhich will-not appreciably reduce the partial vacuum which is necessary for the operation of the refining device. This may be accomplished by limiting the admission openings 20, 20 but it is preferred to use the needle valve 22 for this purpose.
Having thus described the invention, what is claimed as new'and desired to be secured by Letters Patent is r 1. In anoil refining apparatus for hydrocarbon engines, the combination with a refinin chamber, means for creating sub-at mosp eric'pressure in said chamber, a reservoir for oil beneath the engine, a tube for conveying oil from said reservoir to said refining chamber, and means for admitting air to the lower part of the tube to lighten the oil and absorb diluents therein;
