Heater and Vaporizer for Internal-Combustion Engines, of which the following is a specification.
Our invention relates to internal combustion engines such as are now constructed to burn gasolene, or similar hydrocarbon fuels.
The principal object of the invention is to provide means whereby heavy hydrocarbon oils of low boiling point may be utilized in such an engine. This is accomplished by vaporizing the oil by means of the engine exhaust and by mixing the oil with suitable proportions of steam, the mixture then being further heated before being passed into the carbureter.
The invention comprises means whereby a very light and volatile fuel may be used for starting purposes, and means whereby the user of the engine can at any time change the apparatus so that either, high or low boiling point fuel may be used.
In the drawings, which are for illustrative purposes onlyzFigure 1 is a somewhat diagrammatic cross section of an automobile equipped with our invention. Fig. is an enlarged View, partly in cross sect1on,'of our invention as applied to the exhaust pipe of an internal combustion engine. Fig. 3 is a cross section on a plane represented by the line w m of Fig. ,2. Fig. 4 is an enlarged cross section of the-water connection and radiator cap of the automobile. Fig. 5 is a cross sectional plan view of the valve. Fig. 6 is a cross section on a plane represented by the line ov -w of Fig. 5, looking in the direction of the arrows.
The invention is illustrated as applied to an automobile, this being the most common application of internal combustion engines.
1n the drawings, an automobile 11 is shown on which an engine 12 is mounted, the engine having a carbureter 13. A radiator 14 is connected through pipes 15 and 16 with the water jacket of the engine, the radiator being provided with a water connection 17 and a cap 18 through which the radiator may be filled. An exhaust 'mani fold 19 is connected through a pipe 20 with a muflier 21. Located under the seat 22 is a may be placed in the tank 23. A vaporizing,
chamber 30, having a cross section similar to that shown in Fig. 3 adapted to fit against the exhaust pipe 20, is secured to the exhaust pipe by means of aclamp 31 arid by means of a small copper pipe 32, this copperpipe 32 being wound around the vaporizing chamber 30 as shown in Fig. 2, the exhaust pipe 20, vaporizing chamber 30, and the pipe '32, being insulated by an asbestos covering 33. Located in the vaporizing chamber 30 are a series of baffle plates 34, and located near the lower end thereof are a series of screens 35. A pet-cock 36 is provided at the lower end of the vaporizing chamber 30 through which waste water, dirt, etc., may be drawn as they accumulate. The lower end 37 of the pipe 32 is connected into a T 38, one branch of which is connected through a pipe 39 with the interior of the main tank 23. The other branch of the T 38 is connected through a pipe 40 with a change-over valve 42. The upper end 43 of the pipe 32 is connected to a 'l' 44, one branch of which is connected through a pipe 45 with the upper end of the vaporizing chamber 30, the other branch being. connected through a valve 46 with a pipe 47 v the pipe 47' extending into the interior of valve 42 with the auxiliary tank 25, the
upper projection 53 of the valve 42 being connected through a pipe 54 with a projection 55 formed on the vaporizing chamber 30. The valve 42 has the construction illustrated in Figs. 5 and 6 in whichv the shell has the projections 41, 53 and 51 formed thereon, and in addition has a projection 61 which is connected through a pipe 62 with the carbureter 13. A cover 63 closesone end of a cylindrical opening 64 formed in the shell 60, a cylinder 65 turning in the cylindrical opening 64 and being controlled through a stem 66 which projects through a stutling box 67 formed in the cover 63. An operating rod 68 extends through the fioor 69 of the automobile 11 so that the cylinder can readily be turned. A right angle opening 7 0 is formed in the cylinder 65, the opening 7 0 connecting with an openthe engine .12, the-valve 65 is turned by means of the rod 68 into such a position that the pipe 40 connects directly With the pipe 62, the pipes 54 and 50 being closed by the cylinder 65. Gasolene is then taken from the tank 23 directly into the carbureter 13 in. accordance With standard practice in the art, the automobile operating in the ordinary manner. If it is desired to burn a heavy distillate the cylinder 65 is turned so as to connect the pipe 54 with the pipe 62, the pipes 50 and 44; being closed. The heavy distillate is then taken through the pipe 54: into the pipe 32, passing around the exhaust pipe 20 and around the vaporizer 30, the heated liquid being discharged through the pipe. 45 into the top of the vaporizing chamber 30. If the valve 46 is closed,'there Will be no flow through the pipe 47. If it is desired the valve 46 may be opened, Water vapor being taken off the top of the radiator 14: through the pipe 47. The amount of this water vapor Will depend largely on the temperature of the engine, large amounts of this vapor being taken off as the water in the jackets of the engine approaches or passes the boiling point. The heated fuel and the Water vapor pass downwardly through the vaporizing chamber 30, being broken up and mixed by the diaphragms 34 and being finely subdivided and further mixed by the screen members 35. The finely divided and mixed Water vapor and fuelare drawn through the pipes 5% and 62 into the carburetor where the liquid is further vaporized before being passed into the engine. When heavy fuel is used in the main tank 23, it is extremely difficult to start the engine when cold, due to the low boiling point of such heavy hydrocarbon. For the purpose of making starting easy, the auxiliary fuel tank 25 is supplied, a small quantity of light gasolene being carried therein for starting. When it is desired to start the engine, the cylinder 65 is turned so that the pipe 50 is in communication With the pipe 62, light gasolene being then taken from the tank 25 into the carbureter 13 so that the engine can be started in the usual manner.
