Application filed July 7, 1921, Serial No. 483,035, and in France August 2, 1920.
The invention relates to an improvement in carburetors designed for the selective use of light and heavy hydrocarbons, with means for vaporizing the heavier hydrocarbon beyond the carburetor and delivering it to the carburetor for mixing with the air.
The improved carburetor is provided with means for controlling the air admission, means for controlling the passage of the lighter hydrocarbon to be mixed with the air, means for controlling the passage of the heavier hydrocarbon beyond the carburetor to the vaporizer, and means for controlling the passage of the vaporized heavier hydrocarbon for admixture with the air, all said means being governed by the movement of a single element and being simultaneously and similarly controlled.
The invention is illustrated in the accompanying drawing, in which the View illustrates the improved carburetor in longitudinal section, partly in elevation, a vaporizer heated by the exhaust products of combustion of the engine, and connections between the vaporizer and carburetor illustrated diagrammatically.
Referring to the drawing, 1 is a stationary cone, cooperating with a movable circular disc 2, these two parts constituting the air admission device of the carburetor. The admission device for volatile petroleum or any other light fuel adapted to be used in a liquid state, is constituted by a movable cone 3, cooperating with a circular or cylindrical passage 4, which opens into a chamber 5. Said chamber 5 may be provided with stuffing boxes 6 and has slots 7, through which atomized fuel may freely pass into the air current passage 7 at any rate of speed of the engine.
The fuel pipe for feeding the lighter hydrocarbon to the apparatus is connected thereto at 8, and is provided with a cock 8 or the like. A stuffing box 9 is provided to secure local tightness.
The device for feeding lamp-oil or any other heavy fuel intended to be vaporized is formed of a movable cone 11 cooperating with a circular or cylindrical passage 10.
The fuel pipe is connected at 12 and provided with a cook 12 or the like. The fuel admitted through device 1011 flows through pipe 29, connected at 13 to the carburetor and 1S vaporized in the vaporizer 30.
Said vaporizer is heated by means of exhaust gases of motor 31.
The means whereby vapors from the vaporlzer are admitted to be mixed with air comprise a movable cone 16 cooperating with ac'lrcular or cylindrical passage 17, the vapor pipe 32 from thevaporizer being connected at 18 and the pipe 26 through which vapors are conducted to the place where they are to be mixed with air being connected at 19. Stuffing boxes 21 and 22 secure the tightness of this portion of the apparatus.
The spindle 20 is movable longitudinally and carries the circular disc 2 as well as said cones 3, 11 and 16. Said spindle is to be con nected according to the various conditions of application of the invention to exterior operating devices, which may be of any well known type. The carburetor is made up of several separable'sections, at least three such being employed, involving primarily a central or hot section and end sections through which the respective fuels are admitted and controlled. Bolts 23 are used in the present form of construction for the purpose of spacing the hot portions 16, 17, 18 and 19 of the apparatus as far as possible from the remaining portions which are to remain in a cold condition. The part 24 is screwed onto the air and fuel admission devices, cold air being admitted thereto at 25. A. pipe 26 connects the fuel vapor admission device to the device 27-28, wherein fuel vapors will be mixed with air in accordance with the consumption of the engine. It, therefore, results that the explosive mixture is not produced within the carburetor, but between the exhaust part of the carburetor and the motor valves, whereby the carburetor functions only in correctly proportioning the various parts making up the mixture.
When the engine is stopped, both the cocks 8 and 12' are cut off. For starting, which cannot be obtained with lamp oil, cock 8 corresponding to the light fuel is opened.
The driver operates the spindle 20 and this liquid hydrocarbon is admitted to the car buretor together with the air required for the combustion and then rotates the motor crank (cock 12' being shut 01f although the admissions 11 and 1617 are open, owing to I the displacement of spindle 20).
sov
The motor starts and may run indefinitely with light oil, but as the heating value of the lamp oil is much higher than that of the light oil (liquid hydrocarbon), it is convenient that, after starting, lamp oil in the form of vapors be used.
With this object in view, cock 12 is operated, whereby lamp oil is fed to the vaporizer, after which the admission of the vapors produced in the vaporizer to the carburetor itself, is opened. Atthe same time, cock 8 may be cut 01?. The. vaporizer is heatedby the combustion gases from the motor.
What I claim to be new is 1. In ,a carburetor designed for the useof heavy or lighthydrocarbon made up of several interconnected body portions, one of such body. portions having an, air inlet, a mixture outlet, a valve controlling communication between the air inletandfuel outlet, a light hydrocarbon inlet, avalve controlling communication between the light hydrocarbon inlet andthe fuel outlet, a second body portion spaced from thefirst mentioned body. portion and including a heavy hydrocarbon vapor inlet, a heavy hydrocarbon vapor outlet leading to andcommunicating with the fuel outlet of the first mentioned body portion, .a valve arrangedbetween the said inlet and outlet of the second body portion, a third body portion spaced from the second body .portion and having a heavy hydrocarbon inlet outlet andaheate d by the exhaust gasesof an engine, a lighter hydrocarbon inlet. formed in the carburetor, a valve for controlling the lighter hydrocarbon and the air admltted through the air inlet, a means of communication between the vaporizer and thecarburetor through which the vaporized heavy hydrocarbon is directed, an outlet from the car-.
buretor for the vapor of the heavy hydrocarbon, said outlet leading said vapor to and mixingitwith the air from the air inlet at a point beyond the admixture. ofthe lighter hydrocarbon with said air, anda valve for controlling the passage of the vaporized heavy hydrocarbon through the carburetor to the outlet therefor, that. .part of the carburetor arranged forthe passage of the heavy hydrocarbon vapor being spacedfrom the remainingparts of the carburetor to avoid undue heating of such remaining parts.
