FUEL VAPORIZING DEVICE FOR GASOLINE ENGINES Filed Aug. 7. 1951 Patented May 22, 1934 UNITED STATES PATENT? OFFICE FUEL VAPORIZING DEVICE FOR GASOLINE ENGINES 1 Claim.
the gasoline drawn into the intake manifold of an internal combustion engine.
The object of the invention is to provide means which may be placed in the intake manifold for heating up the gasoline as it passes from the carbureter into the engine to more thoroughly vaporize the gasoline and thus provide a more highly combustible fuel charge.
A further object is to provide a device of this kind which will not impede the flow of gasoline vapor through the intake manifold.
The object of the invention is effected by providing a heating coil within the passage leading from the carbureter into the engine, this coil being in circuit with the starting switch whereby when the starting motor is turned on the coil will be heated to vaporize the gas which contacts with it.
Referring to the accompanying drawing, which is made a part hereof and on which similar reference characters indicate similar parts,
Figure 1 is a view in elevation of a carbureter having my device applied thereto showing the starting motor circuits in a conventional manner,
Figure 2, a section on line 22 of Figure 1, and
Figure 3, a detail view of a gasket showing the resistance heating coil attached thereto.
In the drawing numeral 10 indicates a carbureter which may be attached to the intake manifold 11 of the engine by means of flanged joint 12. Instead of the usual packing element inserted between the flanges 12 I provide a packing element shown in detail in Figure 3 which is made up of metal plates 13 and 14 having suitable insulating material 15 between them. An insulating disk 16 is also placed between the plate 14 and the lower flange 12 of the joint. The whole assembly is tightly secured in position by the usual bolts 17. To the lower plate 14 is attached an ear 18 carrying a screw 19 for securing an electric cable 20. The inside of the lower plate 14 has an car 21 to which is attached one end of a resistance coil 22, the otherend of the coil being secured to an car 23 extending in from the plate 13. The cars are preferably attached to the ends of the coil 22 by wrapping about them and then being welded thereto. Suitable eyelets 24 of insulating material are provided through which the bolts 17 pass. The cable 20 is attached to a post 25 to which one line 26 leading to the starting motor 27 is attached. The post 25 is on the starting switch 28. When the starting switch 28 is closed circuit is completed through This invention relates to means for vaporizingline 29 with the battery 30 and simultaneously with the starting of the motor 27 circuit is closed through the line 20 to the resistance coil to heat up this coil and to vaporize the fuel which is sprayed from the carbureter into the intake manifold 11. The resistance element 22 lies substantially in a plane parallel with the axis of the intake manifold and hence offers practically no resistance to the passage of the fuel charge from the carbureter into the intake manifold of the engine. From the construction shown it will be seen that the resistance element presents only the edge of a grid-shaped resister to obstruct passage of fuel mixture through the intake manifold. Because of this the element 22 offers no appreciable diminution of the volumetric capacity of the intake manifold. The resistance element moreover is so arranged that expansion and contraction in no way affect it. The ears 21 and 23 are wrapped around the ends of the resistance element 22 so that these cars form a tube of steel around the ends of the coil. The ends are then fused by welding to the cars so as to insure perfect contact. By having the ears wrapped around the ends of the coil and then welded to them perfect fusion of the two metals is insured without danger of over-heating either of them so as to cause crystallization which would readily break. The resistance coil is located directly over and parallel with the throttle valve shaft 32 so that even with a wide open throttle no additional resistance surface is present to prevent or restrict the flow of fuel through the manifold. The coil delivers heat to the fuel in the intake manifold. The metal quickly heats up because it is not in thermal contact with any large heat absorbing bodies. The coil moreover catches any unevaporated gasoline which drips back from the manifold and tends to vaporize it. The heating element is located above the cold portions of the carbureter so it does not lose its heat to the metal parts but delivers all of it to the fuel passing through the manifold. The coil is automatically energized when the starting switch of the motor is closed and circuit is interrupted at the instant the starting motor is disconnected from the battery; this is as it should be.
At 31 is shown an auxiliary switch. This switch will be closed, in case the car is cranked by hand. This also may be any manually operated auxiliary switch which is closed independently of the switch to the starting motor.
It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention plates, a grid formed of a plurality of bends lying in a single plane attached at its ends at a right angle to said conducting plates, said grid lying in a plane parallel with the axis of the throttle valve of said carburetor thereby offering least resistance to flow of fuel from said carburetor to said manifold, one of said conducting plates being grounded and the other of saidconducting plates connected in=para11elwiththe starting motor of the vehicle on which the carburetor is mounted, substantially as set forth.
