This invention relates to internal combustion engines, and more particularly to a means whereby kerosene may be used and burned in an internal combustion engine.

5 At the present time in the operation of certain internal combustion engines kerosene is used as a combustible fuel, but in the use of this fuel it is necessary to provide an auxiliary jet or carburetor whereby gasoline may be initially used so as to heat up the engine to the point where the kerosene will readily vaporize. It is, therefore, an object of this invention to provide a means whereby kerosene may be used during the entire operation of the engine, making it unnecessary to switch from one jet or carburetor to another while the engine is in operation.

Another object of this invention is to provide a structure which may be used with the present parts of a motor vehicle or internal combustion engine, it being only necessary that the carburetor at present in use be adjusted to take care of the heavier fuel or replaced.

A further object of this invention is to provide a structure of this kind wherein the fuel is discharged into a. relatively small receptacle in which the fuel is heated to the desired degree and then periodically discharged into an auxiliary tank positioned relatively close to the engine, the fuel flowing by gravity from the auxiliary tank to the carburetor.

A still further object of this invention is to provide a structure of this kind including an auxiliary battery which is used to provide heat for the heating tank, so that the fuel may be heated before the starting of the engine in order that the fuel will be of the proper temperature to vaporize.

With the foregoing and other objects in view, the invention will be more fully described herein- 4 after, and will be more particularly pointed out in the claims appended hereto. 1

Referring to the drawings, the numeral i0 designates a motor vehicle frame structure having wheels II, a radiator i2, hood l3, and a dashboard An engine E is mounted beneath the hood l3 between the radiator l2 and-the dash- 5 board H. The engine E is provided with an intake manifold l5 to which a carburetor i6 is connected. A fuel pump i1 is associated with the carburetor l6, and the pump I1 is connected to the intake manifold [5 by means of a suction 10 pipe i8. While a suction operated pump i1 is here shown, it will be understood that a mechanically operated pump may be used in place of the pump ii.

The hereinbefore described structure is con 5 ventional and is here shown as one type of internal combustion engine structure with which the hereinafter described invention may be associated.

A main fuel tank i9 is disposed at the rear of 20 the frame l0 and is provided with the usual filler neck 20. The tank i9 is connected to the suction pump I! by means of a pipe 2i which has its intake end disposed closely adjacent the bottom of the tank 13, as shown at 22. A fuel heating 25 tank, generally designated as 23, is supported on brackets 26 which are secured to the upper portion of the dashboard H by fastening devices 25.

The fuel heating member 23 comprises a cylindrical body 26 having a

concave bottom wall

21, 30 and a closure 28 provided with marginal flanges 23 and an air vent 30 engages the upper end of the body 26. A heating element 3i engages about the body 26, and the heating element 3i is constructed in the form of an electrical heating ele- 35 ment or coil which contacts with the cylindrical body 26. An outer Jacket 32 engages about the heating element 3i and is preferably formed of insulation so as to retain the heat from the element about the body 26.

An auxiliary fuel tank 33 is disposed below the heating member 23, being supported on bracket means 34 secured by fastening devices 35 to the dashboard ll. The tank 33 comprises a cylindrical body 36 provided with a concave bottom 31 and a closure or top wall 38 having marginal flange 33. The tank 33 is surrounded by a heat insulating jacket so that when the heated fuel is discharged thereinto from the heating member 23 the fuel will not readily dissipate its heat.

The tank 33 is connected to the heating member 23 by means of a pipe I which at one end is connected to the bottom wall 21 of the heating member 23, and at the other end is connected to the lid or closure 38. The outlet or discharge side of the pump I1 is connected to the heating member 23 by means of a pipe 42. The pipe 42 isconnected to a valve housing 43 which is secured to the underside of the closure 28, as shown in Fig. 4, and a valve plug 44 is movable in the housing 43. The housing 43 is provided with an outlet port 45 discharging into the interior of the heating member 23, and an arm 46 is carried by the plug 44.

A buoyant member or float 41 is disposed within the heating member 23, being secured to a rock lever or rod 48. The lever 48 is rockably mounted on a shaft 49 which is journalled in a bearing structure 50 fixed to the inside of the body 26 adajcent the lower end thereof. An arm 5| is also fixed to the shaft 49 and is provided with an eye 52. The arm 5|, as shown in Fig. 4 is disposed on an obtuse angle to the length of the rod or lever 48, and a link 53 connects the eye 52 with the plug arm 46 so that vertical rocking of the lever or rod 48 under the action of the buoyant member or float 41 will move the plug 44 to either a. closed or open position.

A cylindrical bushing or boss 54 provided with a bottom flange 55 is secured to the concave bottom 21 within the heating member 23 and in axial alinementwith the pipe 4|. The flange 55 is provided with a valve seat 56, and the bushin or boss 54 is provided with fluid passages 51 which communicate the heating member 23 with the pipe 4|. The bushing or boss 54 is provided with a relatively large bore 58 within which a valve plug or member 59 is adapted to engage. The valve plug or member 59 when in port closing position is adapted to engage on the seat 55 so as to thereby cut ofi the flow of fuel from the tank or heating member 23 to the auxiliary thermal tank 33.

The upper or inner end of the bushing or boss 54 has a cap 60 threaded thereonto, and the. cap 60 is provided with a central bore 6| through which a valve stem 62 slidably engages. The valve stem 62 is secured to the valve plug 59 and extends vertically and axially within the body 26. The stem 62 adjacent the upper end thereof is provided with a notch 53, and a second notch 54 is disposed adjacent the lower end of the stem 62, being positioned diametrically opposite from the notch 63. The lever 48 has a valve lifting dog 65 secured thereto by means of a pivotal member 68, and a relatively light spring 51 is carried by the lever 48 and engages the dog 65 so as to constantly urge the dog 55 toward the stem 52.

A valve holding dog 61 is rockably mounted on cars 68 carried by the cap 60, and an arm 59 is formed with the dog 61 and extends laterally of the cap 60. A spring 10 is carried by the cap 60 and engages the arm 69 so as to constantly urge the dog 61 toward the stem 62. The lever 48 is provided with a laterally projecting dog releasing pin 1| which when the float 41 is in the lowermost position is adapted to engage the arm 69 so as-to rock the dog 61 to a released position and permit the valve member 59 to drop downwardly to a port closing position. At the time that the float 41 is in its lowermost position, the valve plug 44 is moved to an open position by means of the arm 5|, link 53 and arm 45, so that the fuel will be discharged into the heating member 23.

The heating member 23 has the element 3| thereof energized by means of a battery 12 which is suitably mounted on the frame l0, and this battery 12 may be in addition to the usual battery 13 which is used in the normal operation of the motor vehicle. The battery 12 is connected to the heating element 3| by means of a wire 14, and a switch 15 is interposed in the wire 14 so that the heating element 3| may be energized independent of the operation of the motor vehicle. The battery 13 may also be connected to the switch 15 by means of a wire 15 so that when desired or necessary the battery 13 may be used to energize the heating element 3|.

In the use and operation of the motor vehicle embodying this invention, the switch 15 is initially operated to close the electric circuit to the heating element 3|. It will be understood that one side of the heating element 3| is connected to the frame Ill, and that one side of the battery is grounded to the frame I0, so that in practice only one wire is necessary to connect the heating element 3| with the battery 12 or the battery 13. The engine E may be initially turned over with the usual starter so as to effect operation of the pump I1 and cause a quantity of fuel to be drawn from the supply tank I!) through the pipe 2| and pipe 42 and discharged into the heating member 23. Assuming that the heating member 23 is initially empty, and that the float 41 is in the position shown in full lines in Fig. 4, the'valve plug 44 will be held in an open position permitting the fuel to be freely discharged into the heating member 23. At this time the valve plug 59 will be engaged with the seat 55 so as to cut of! flow of the furl through the pipe 4| to the auxiliary thermal tank 33. The switch 15 may now be closed so as to energize the heating element 3| and thus heat up the fuel in the heating member 23.

The size of the heating member 23 is substantially smaller than the auxiliary thermal tank 33 so that only a relatively small amount of fuel will soon fill this member. As the float 41 rises in the heating member 23 the lifting dog 65 will engage in the notch 63 of the stem 52 and thus lift the valve 59 to an open position. When the valve 59 is in an open position the dog 61 will be disposed in a position confronting the notch 54 and will be moved thereinto by means of the spring 10 so that the valve 59 will thus be held in an open position until the float 41 is lowered.

When substantially all of the fuel in the heating member 23 has been discharged through the pipe 4| into the auxiliary thermal tank 33 the pin 1| carried by the lever 49 will strike the arm 59 carried by the dog 61 and swing this dog to a released position, permitting the valve 59 to gravi tatingly drop to a closed position. The fuel in the tank 33 may freely flow to the carburetor I5. If desired the hot exhaust gases from the engine E may be made to circulate about the heating member 23 and/or the auxiliary thermal tank 33, so that after the .engine E has been started the heating element 3lsrnay be cut 01!.

With a structure or this kind the cheaper and heavier fuel, such as kerosene or the like may be used to run the engine, and this fuel may be used during the entire engine operation.
