HAROLD T/V. FENLIN G- ATTORNEYS Patented Apr. 19 1932 PATENT OFFICE CYRUS J. WELLSAND HAROLD W. FEMLING', OF SEATTLE, WASHINGTON METHOD OF INTRODUCING HIGHLY VOLATILE LIQUIDS INTO AN ENGINE CYLINDER,

Application filed March 9,

Our present invention relates to the art of internal combustion engines and more particularly to a method of introducing highly volatile liquids into an engine cylinder.

Internal combustion engines of the type ordinarily designated as gas engines operate by inducing into their combustion chamber in rapid succession an explosive mixture of alr and liquld fuel. However, in recent '10 years in the interest of general conservation ether may be taken as an example.

Many persons have used ether by mixing the same with the gasoline in the large gasoline tank provided. This has proven to be not only unsatisfactory but very dangerous.

WVhen a small amount of ether is put in a comparatively large gasoline tank which tank is vented out of necessity, it soon goes out of solution and is vaporized and lost. Further, when there is considerable space in the gasoline tank the volatilized ether and the fumes of the gasoline produce an ex tremely sensitive explosive mixture and many serious accidents have resulted from this use of ether. Therefore, I V

The purpose of our invention is to PI'OVIClG a method of introducing ether, or like volatiles, into the combustion chamber of a gasoline motor.

A further object is to provide means for 1ntroducing ether into a combustion chamber which provides a more or less uniform flow, at the same time almost entirely eliminating any hazard.

Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawings, wherein Figure 1 is a vertical sectional view showing a device which may be satisfactorily used M in rrying out our method.

1931. Serial No. 521,216.

Figure 2 is an elevation showing the device of Figure 1 and its general relationship to a gasoline motor.

. Referring to the drawings throughout which like reference characters indicate like parts, numeral 10 designates the vapor bowl which may be provided with a bracket suitable for bolting the'same in place, as shown at 12. Disposed near the lower portion of dome 10 are a series of filter screens 14,.whose purpose is to finally divide the oil vapor. As a matter of convenience so as to be able to tell definitely whether the device contains oil or' not, we provide a transparent glass 16, which in turn is supported with the base member 18. A central tube member 20 is provided to hold the aforementioned members together in operative'relationship and also to provide means for conducting air through the intake openings 22 down its central passageway 24 and out the discharge openings 26. Dome member 10 is provided at some convenient point with a discharge fitting 28 to which is suitably attached a section line 30 which is attached to the intake manifold of the motor the device is to serve.

Method of operation It has been found that when ether or like high volatiles are introduced into the combustion chamber of a motor, extremely high temperature is maintained and to counteract this condition it has been found necessary to include with the ether introduced an amount of high flash lubricating oil which will make up for that destroyed by the additional heat. To accomplish our general results, therefore, it has been found necessary to use that class of device ordinarily referred to as an internal combustion chamber lubricator. There are many such devices well developed and on the market, most of which can be used for our purpose. .However, it has been found that the so-called vaporized type is the most satisfactory. A typical example of the same is shown in section in Figure 1.

'the particular motor under trial, approxi- 1 .tilefuel into an engine. cylinder consisting of as indicated; at 32; fTllB'bUlJblGS IWlllCll form? often quite large, quickly saturate the filtering screen 14 and-asthis is normally com-- osed of several thicknesses of co er auze or of felting includedbetween screens, the

air, in passing therethrough picks up, in mechanicalsuspension, the finely divided. partlcles 'of oil and fuel producing in'eifect a saturated vaporwithin the cavity 34. In this manner the mixture is maintained at its proper relative balance, resulting in immedi- [ate introduction into the firing chamber of the highly volatile fuel so desired, together with the proper, predetermined lubricating oil, which will be sufficient to counteract its detrimental: effects.

When used in this manner there is no danger from explosive hazard as the ether and oil do not readily form an explosive mixture asdo gasolineand ether. Further, the container issea-led againstthe introduction of airexcept when. under negative pressure; con sequ'ently there is no loss from vaporizationinto the atmosphere. And, lastly, by the introduction of the proper amountof a satisfactory type" offoil, any. detrimental effects ofthe ether are counteracted. In actual trials even old motors show a remarkablyv increased performance.

The foregoing description andthe accompanying drawings are believed to clearly. disclose a preferred embodiment of our invention but itwill be'-un'derstood-that this dis- ..closure is merely illustrative and that such changes in the invention may be. made as are fairly within the scope and spirit of the following claims:

. 1. The method of introducing; highly volatile fuel into an engine cylinder consistin of mixing the highly volatile fuel with a In ricant placing thesame in an internal combustion chamberlubricator and connecting, the

outletjof saidlubricator to theintake manifold of the motor.

;said lubricator to the intake manifold of the motor.

3. The method of introduoinghighlyvolaternal combustion chamber lubricator and connecting the'outlet of said lubricator to 30 ,the intake manifold ofthemotor.
