REVAPORIZER FOR INTERNAL-COMEUSTI ON ENGINES.
Application filed January 3, 1911.
and State of Pennsylvania;have invented certain new and use't'al improvements in -Revapor1zers tor IIICEl'IlEllCOlHbUSUOI] Engines; and I do hereby declare the followmg to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to internal con'ib-ustion enginesand especially to means for revaporizing any raw fuel which may become condensed during the passage of the vapor from the carbureter to the cylinder of the engine.
The pipe leading from the carburetor to the cylinder often becomes covered with frost even in warm weather, due to the rapid vaporization of the fuel. The coldness of this pipe has a tendency to condense the vapor during its passage therethrough, forming drops of raw fuel which pass into the cylinder with injurious etlect. Furthermore, the high velocity oi the air passing through the carbureter often carries drops of fuel over into the cylinder without giving said drops a chance to become VHPOLiZOtl. This unfavorable condition is becoming more prevalent because ol the tact that the quality of gasolcne obtainable is continually becoming more and more interior.
The object of my present invention is to prevent any rawjl uel from entering the cylinder of the engine. I accomplish this purpose by placing electric condmtors, capable of generating heat. In the pipe leading iroln the carbureter to the cylinder. The etl'ect of these electric comluctm's is to revaporize any drops of raw fuel which may be condensed in said pipe with the result that when. the vapor enters the cylmder, it is entirely free from raw t'uel.
My invention consists in the construction 7 and arrangement of the electric conductors,
which I employ, in combination with the essential operative parts of an internal combustion engine.
Particular features of construction and combinations of parts constituting my invention are specified. in the appended claims.
In the accompanying drawing illustrating the preferred. embodiments ol? my invention: Figure l is a sectional view of a car- Specifieation of Letters Patent.
Patented Sept. *2, 1915: Serial No. 600,482.
bureter, a part of the cylinder of an internal combustion engine, and the pipe connecting said carbureter and cylinder, showing my revaporizer in operative position. The carbureter and cylinder are shown conventionally, my revaporizer being capable of attachment to engines of various known types. Fig. 2 is an enlarged sectional view of the pipe leading from the carbureter to the cylinder showing the revaporizer more in detail. Fig. 3 is a cross section on the line of Fig. 2, looking in the direction of the arrow. Fig. t is a cross section on the line y-y of Fig. 2, looking in the direction of the arrow, and Fig. 5 is a sectional view of a modified construction of revaporizer.
Referring more particularly to the drawing, 1 designates the carburetor to which air is furnished by the intake pipe 2 and into which the fuel is delivered by the pipe 3.
4. represents the cylinder of the engine connected to the carlnureter by the pipe 5. This is preferably made in sections 5 having their adjacent ends'provided with outwardly extending flanges (3.
My revaporlzers 7 are made in the form o'l rings or short tube sections also provided I with outwardly projecting flanges S at their ends, whereby they may be readily inserted between the pipe sections 5 andsecured by means of bolts 9 passed through said flanges 6 and 8, and quickly removed for repair or replacing.
The ring or tube section 7 of each of the revaporizors has an annular groove 10 formed in its interior surface. This groove contains insulating material 11 in which the bonds of an electric conductor or wire 12 are inserted. The parallel portions of Wire. or conductor comprise the. strands of a grid which extends entirely across the interior of the ring 7. I prefer to use number 20 wire for the electric conductor but it should be understood that other gages of wire or other conducting material may be employed without departing from the spirit of my invention. Vi hen number 20 wire is used, the grid should comprise about twenty-five cross pieces or strands to secure the bestresults.
One or more of the Vaporizers or grids may be inserted in the pipe leading from the carburetor to the cylinder. It is preferahle to use a plurality and to place adjacent grids so that their cross pieces extend transversely to one another. I have illus trated two grids or revaporizers in the accompanying drawing but more may be added if found necessary or desirable. It will be observed that, as shown, the cross pieces of one grid are arranged transversely to those of the other, as above explained. The
electric conductors or Wires constituting the grids may be connected in series, parallel, or in any other suitable manner. I have shown themv connected in series. It will be understood, of course, that the terminals of the conductors are connected to a suitable I to revaporize at the second or subsequent stage any raw fuel which may pass through the first grid. The cross pieces of the second grid are arranged transverse to those of the first grid in order to insure drops of fuel which pass through the first grid coming in contact with the second one. It will be observed that the transverse arrangement of adjacent grids causes the vapor, and such raw fuel as it may contain, to travel a tortuous path through the pipe leading from the carbureter to the cylinder, thereby decreasing the Velocity of said vapor to some extent and giving the grids a better opportunity to perform their function of revaporizing the raw fuel.
In order to further lessen the velocity of the vapor as it passes through the pipe connecting the carbureter and cylinder, the grids or revaporizers may be mounted in enlarged globe-shaped couplings 13, as illustrated in Fig. 5. These couplings are provided with flanges 14 at their ends and are attached to the sections of the pipe leading from the carbureter to the cylinder in the samemanner as the rings or tube sections 7, already described. I
