1 Claim.
combustion engine and the carburetor for positioning the carburetor at a more remote position relatively to the engine and for providing a conduit for the fuel mixture and by which said mixture will be conveyed by a circuitous route and subjected to heat from the engine in its travel between the carburetor and intake ports of the cylinders to promote vaporization of the fuel mixture and a more complete combustion of the fuel in the combustion chamber, to thus improve the operating eficiency of the engine and to reduce the fuel consumption thereof.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a preferred embodiment of the invention, and wherein:
Figure 1 is a side elevational view looking toward the side of an engine, of the internal combustion type, which is disposed remote to the side thereof through which the fuel mixture is admitted to the cylinders;
Figure 2 is a top plan view of the invention as illustrated in Figure 1;
Figure 3 is a side elevational view looking toward the opposite side of Figure 1; and
Figure 4 is an end View in elevation looking from front to rear of the engine.
Referring more specifically to the drawings, for the purpose of illustrating one adaptation of the invention, hereinafter to be described, 5 designates generally the upper portion of an internal combustion engine having an exhaust manifold 6 extending along one side I thereof and an intake manifold is on the opposite side 9 thereof and which is connected to a plurality of intake ports I o of said sides 9. A conventional carburetor H including a fuel supply line 52 and an air intake passage i3 is shown mounted above and to one side of the engine 5 and adjacent the sides 9 thereof.
Instead of the carburetor it bein disposed in close proximity to the side 9 and connected at its outlet end It to the intake manifold 8, the invention provides a conduit, designated generally having an inlet end It which is connected to the bottom or outlet of the carburetor H and which extends downwardly therefrom, as best seen in Figure 3. The portion I6 of the conduit l5 merges with the rearwardly extending portion I! thereof which extends along the side 9 rearwardly and in converging relationship thereto and which is inturned to form the conduit portion l8 which extends across the rear end of the engine 5. The conduit i5 also includes a portion H] which merges with the opposite end of the portion l8 and which is disposed at substantially a right angle thereto. The portion 19 extends along the side I of the engine 5 and is preferably disposed in close proximity thereto and preferably beneath and adjacent the exhaust manifold 5. The forward end of the portion i9 merges with a transverse conduit portion 22 which extends transversely across the forward end of the engine 5 and to beyond the side 9 and which is turned rearwardly to form the conduit portion 2! having an inturned rear end 22, forming the opposite end of the conduit 5 5 and which is connected to and communicates with the intake manifold 83, preferably intermediate of the ends thereof.
From the foregoing will be readily apparent that the mixture of fuel and air from the carburetor 5! passes through the various portions of the conduit i5 and in the direction as indicated by the arrows 23, by a circuitous route to the intake manifold 8 and therefrom to the intake ports it of the engine 5. It will be readily obviou that the fuel mixture will be vaporized in its passage through the conduit l5 due to the distance of its travel between the carbiu'etor and intake manifold and also and more particularly because of the fact that the fuel is subjected to the heat from the engine 5 and its exhaust manifold S in passing therearound, so that the fuel mixture will be in a highly vaporized state when admitted to the combustion chambers, not shown, of the engine 5 to thus cause the engine to oper ate more efficiently and with a considerable saving in fuel consumption Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit and scope of the invention as hereinafter defined by the appended claim.
I claim:
An attachment for the fuel supply system of an internal combustion engine, comprising a fuel supply conduit adapted to be interposed between the intake port of an engine and the carburetor thereof, said conduit extending substantially entirely around the engine to provide an indirect and circuitous passage for the fuel mixture from the carburetor to the intake port and for subjecting the fuel mixture to the heat radiated from the engine, for thoroughly vaporizing the mixture during its passage from the carburetor to the fuel intake port, said conduit having portions disposed in close proximity to at least one side and both ends of the engine and including a portion disposed longitudinally of and in close proximity to a portion of the exhaust manifold.
