Application led April 15,
To @ZZ 107mm t may concern Be it known that l, Ennnsr B. FAHNE- s'rooii, a citizen of the United States of America, and a resident oi lllandome, county of Nassau, and State of New York, have invented certain new and useful linprovements in Conduite for Volatilized Fluids, of which the following is av specification, reference being had to the accompanying drawings, forming,v a part thereof.
My invention relates to new and useful improvements in conduits for gaseous fuels, and its object is to provide a passage for volatilized fluids which will prevent the condensation thereof.
More specifically, its object is to provide a conduit for the volatilized fuel for internal combustion engines which may be interposed between the fuel supply jet and the engine cylinder in the form ot' a` pipe or chamber and which. is constructed of porous material so arranged that a limited amount of air may pass through its walls.
in order that' my invention may be thor-` oughly understood, l will now proceed to describe the same in the following speciiication, and will then point out the novel features thereof in appended claims.
Referring to the drawings:
Figure l is an elevation partly in section, of an engine and a carbureter of ordinary construction with a conduit which embodies this invention interposed between them.
Figure 2 a plan view partly in section oll au engine malni'liild which also embodies this invention.
YFigure is a sectional end elevation of the conduit shown in Figure l, the section being taken on the line 3-8 of' the ylatter figure. v
Figure 4t is a sectional end elevation of a conduit of modiiied construction which also embodies my invention.
Figure 5 is an elevation part-ly in section, of another arrangement of parts by means of which this invention may be used.
Like characters of reference designate correrrpondinnparts in all the figures.
i0 designates an internal combustion engine, ll its intake and 12 a carbureter of standard construction` The carburetcr is connected by a pipe fitting 13 with one end 1918. Serial No. 222,543.
of a cylindrical member of insulating material l-i, the other end of which is connected by a pipe fitting l5 with the manifold 1l.
16 is an air supply pipe leading from a jacket on the exhaust pipe of the engine (not shown), to a check valve i7 providec with an adjusting spring 18 and connected to an intake port 19 at any suitable point on the member lt.
lWithin the member 14; is a tube 2O ot porous material, in this case of felt., which is separated from the inner surface of the member by a. spiral of resistance wire 2i, wound helica-lly around the tube and connected at its ends with binding posts 2.2-2.3 by means of which it may be connected with a. source of electrical supply. i
Before more specifically describing the structures shown in Figures 2, i and l will point out the operation of this device. A volatile iiuid is vaporized in the carbureter in the usual way and led int-o one end of the tube 2O through which it passes to the engine manifold. 'in such conduits as have been used heretofore, there is a considerabie condensation between the carbureter and the engine and various expedients hare been resorted to to overcome this diiiiculty. rilie passages are usually made of small diameter in order to maintain a high velocity of the gases even at low engine speeds.` which detracts from the efficiency of high speeds. in this ease this is not nec essai-y. llthatever yfuel has a tendency to condense, settles on the porous tube and air coming through the port if) goes through the wall of the tube and revolatilizes such condensed fluid. tfheated air is led through the pipe 16, its heat increases its volatilizing effect.
When it is desired to supply water vapor to the engine, steam either with or without air may be introduced by a pipe through the port 19.
if a` further heating edect is desired, an electric current may be passed through the resistance wire 2l. This is particularly desirable in starting;y especially with a fuel which does not readily volatilize at atmospheric temperatures, such as kerosene. The amount of air which is permit-ted to pass through the wall of the tube 2O may be regulated by adjusting the spring lt of the check valve.
In Figure 2 the engine manifold is shown as constructed of two parts 30 and 3l, Which are adapted to be aiiixed to an engine, and a third member 32 Within which and spaced from the inner surface thereof by a 1vire coil 33 is a porous tube Bil. The volatilized fuel is admitted to the inside of the tube 34- through a port and air is admitted to the inside of the member 32 and outside the tube 34. through suitable ports (not shown), similar to port 19 of Figure l which may be vulve controlled if desired.
The operation of this structure is like that already described.
It is not necessary that the porous tube be made of felt as any other suitable material maybe used. For example, in Figure d, a section of a tube is shown made of spirally wound metallic screen 38.
Figure 5 shows a simple arrangement of pa-rtsin which 50 designates a porous tube connected at 5l with engine 52. At its other end is a spray nozzle 53 controlled by avalve 55 for admitting a volatile liquid fuel. The length and thickness of the tube and its porosity are in this case so proportioned'thatv enoughair Will pass through` the wall of the tube to make the desired explosive mixture at the engine intake. There is in this arrangement no carburetor other than that formed by the tube.
From the foregoing description it may be seen that When a carbureter is used to adm it volatile fuel and air to the porous conduit, the carburetor needs no mixing chamber beyond its fuel jet. It is also clear that it is not necessary to restrict the area `of the conduit for the purpose of insuring high velocity or to restrict the length of the conduit for the purposes of minimizing condensation. Thus, by the use of this invention one of the serious di'liiculties in the construction and operation of internal combustion engines, is entirely avoided,
Structures of preferred form and construction have been illustrated and described for the purpose of showing ways in which this invention may be used, but the inventive thought upon which this application is based, is broader than these illustrative embodiments thereof, and I therefore intend no limitations other than those imposed by theappended claims.
