To all whom it may concern:
Be it known that I, ALFRED C. STEWART, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented-a new and useful Carbureting Means for Use with Heav Fuels, of which the following is a speci cation.
This invention relates to means for providing a combustible mixture for internal combustion engines by mixing air with vapor of a liquid fuel, such as distillate, which is heavier and less volatile than gasolene, so that it is not readily taken up in the usual carbureting devices.
The main object of the present invention is to provide convenient and effective means for heating the fuel in the carbureting dev1ce.
Other objects of the invention will appear hereinafter.
The accompanying drawings illustrate an embodiment of the invention, and referring thereto: Figure 1 is a side elevation of an internal combustion engine with the carbureting device attached thereto, portions of the latter being shown in section. Fig. 2 is a transverse section on line 01 m Fig. 1.
1 designates an internal combustion engine of any suitable type, which is provided with a water jacket 2 and pipes 3 and doommunicating with said water jacket, pipe 4 leading to the outlet of a pump 5 whose inlet is connected by pipe 6 to the circulating system including the usual radiator. 7 designates the intake pipe or manifold for the engine which is connected to a throttle valve 9, said throttle valve also serving as a means for effecting carbureting or mixing action and being, for example, of the type shown in my application Serial No. 7 90,015, filed September 16, 1913. Said throttle valve may comprise a casing 10 open at its upper end to communicate with a laterally extending chamber 11, which is connected to the outlet of a carbureting device 12,
whose function is to receive the liquid fuel from a supply pipe 13 and to supply it in measured or definite quantities to the air passing through the carbureter from an air inlet 14 to the chamber 11. The inlet pipe 7 opens into the top of the chamber 11 and serves as a guide for a throttle valve member consisting of a tube 16 slidably mounted in the 'lower end portion of the pipe 7 and adapted at its lower end to cooperate with a the bottom of the casing 10 to operate as a throttle valve, the opposing portions 17 and 18 of the tubular member 16 and of the bottom 19 of the casing 10 being corrugated or ribbed as shown, so as to provide a tortuous passage between said passages when the throttle is slightly opened. An 0 crating means'fo'r the throttle valve is provi ed consisting of a crank 20 on a shaft 21, said crank engaging in a neck 22 on the throttle member 16 and said shaft being provided with an operating arm 24 connected to any suitable operating means. 'In place of the combined mixin and carbureting throttling device descri ed, any suitable carbureting device may be used.
A'heating pipe 25 is connected to the cir-' culating systemforthe water jacket of the engine, for example, to the outlet pipe. 3 from the water jacket, said pipe 25 being connected to a heating coil 26 in the exhaust pipe 27 for the engine and said coil being connected by a pipe 28 to a heating coil or heating devlce 30 extending around the casing 10 for the throttle and mixing device.
The operation is as follows: In the normal operation of the engine the heat of the engine cylinder or cylinders warms the water in the water jacket tube and the circulating system connection therewith. A portion of the water passes through the pipe 25 to the coil 26 in the exhaust pipe 27 wherein it is superheated or raised to a higher temperature than that which exists in the water jacket, the temperature of the From the coil 26 the heated water passes through. pipe 28 to the heating means 30 combined throttle, carbureting and mixing device 9, and thence passes by pipe 31'back to the circulating system of the water jacket, the pump 5 making a continual circulation of the water in the above described course. By suitably proportioning the heating coil 26 in the exhaust pipe the water 28 may be raised to any desired temperature suitable for the particular fuel which is being used.
With, the above described arrangement of parts and with the throttle device as constructed and arranged as herein described, and as disclosed in my application above referred to, the said throttle acts as a carbureting and mixing device, as well as a throttle, the carbureter roper serving primarily to supply a definite amount of fuel,
but said fuel being of such nature that it .it is heated suificiently by the heat supplied from the outer casing to. cause the oil tobecome vaporized and be taken up by the alr, so as to carburet the air and form an explosive mixture therewith. On account of the great heat carryin ca-.
pacity of Water it is possible with the a ove described arrangement wherein the water is heated to a relatively high temperature by the exhaust, to supply the necessary heat for insuring complete vaporizing and mixture of a comparatively heavy oil with the Water supplied through a comparatively small'pipe. This invention thereby enables the carbureter to be placed in a most convenient position by permitting the, necessary heat to be supplied thereto without the use of large and cumbersome pipe connections such as are necessary when the heat-of the exhaust is brought directly to the carbureter.
What I claim is:
1. In combination with an internal combustion engine provided with an exhaust and having a water jacket, a water circulatmg system for receiving heated water from the water jacket, carbureting means comprising a means for supplying a mixture of air and liquid fuel, heating means for applying heat to said mixture of air and fuel, a pipe communicating with the water circulatingfmeans and with said heating means to supply heat to the-said heating means from the circulating water, and means for applying heat to the water in said pipe to heat the same above the temperature of the Water jacket of the engine.
' 2. In combination with an internal combustion engine provided with an exhaust and having a water jacket, a water circulat-i ing system for receiving heated water from the Water jacket, and carbureting means comprising a means for supplyinga mixture of air and liquidfuel, heating means for applying heat to said mixture of air and fuel and a pipe communicatingwith the water circulating means and with said heating means to supply heat to the said heating means from the circulating water, said pipe includin a heating means exposed to the heat of t e exhaust of the engine for superheating the Water in said pipe. Intestimony whereof, I have hereunto set my hand at Los Angeles, California this 27th day of August 1913.
