Description
June 17, 1930. LAVERGNE MECHANICAL DEVICE FOR THE SUPPLY OF EXPLOSIBLE GAS T0 INTERNAL COMBUSTION ENGINES Filed April 18, 1927 Patented June 17, 1930 warren stares rarest crates JEAN LAVERGNE, OF PARIS, FRANCE, ASSIGN'OR T RENE FOREST, 0F PARIS, FRANCE MECHANICAL DEVICE FOR. THE STIWPLY OF EXPLGSIBLE GAS TO INTERNAL- COMBUSTION ENGINES Application filed April 18, 1927, Serial No. 184,736, and in France April 24, 1926.
It is observed that in engines employing carburetted gas or air, the admission of the power fluid to the cylinders is effected by the piston during the suction stroke.
This suction produces in the cylinder a pressure which is below atmospheric pressure, and this causes a circulation of the fluid through the carburettor, the conduits and the valves, so as to fill up the vacuum which is set up by the downward strolre of the piston.
For this reason, the pressure of the gas drawn into the cylinder is equal to the atmospheric pressure less the pressure represented by the flow oi the fluid through the carburettor, conduits and valves.
This loss of pressure increases with the speed of. the engine. In this manner the power couple or the engine will decrease, i. e. the weight oi the gas admitted, per revolution of the engine, will diminish progressively according as the speed increases.
My invention has for its object to mechanically compensate for such losses of 25 pressure so as to obtain, irrespectively oi? the speed, a constant weight of gas in the cylinders at each revolution of the engine.
The said invention is disclosed in the following description with reference to the appended drawings, wherein:
Fig. l is a general view showing thefeeding device mounted upon the engine.
Fig. 2 is a sectional view of the injector.
In Fig. 1, 1 is the engine, 2 the carburettor and 3 a mechanically operated compressor; 4 is the injector; 5 and 6 are respectively the suction and delivery conduits of the coinpressor 3; 7 is the feeding conduit for the engine. 1
The injector 4: which is shown in section in Fig. 2, consists of the central nozzle 8, the intermediary divergent element- 9 and the main divergent conduit 10. 11 is the suction chamber of the injector.
The operation is as follows:
A certain portion of the gas from the carburettor 2, which will be termed inducing gas, is drawn through the conduit 5 by the compressor 3, it being compressed to a suflicient degree and then discharged through the conduit 6 into the nozzle 8. Due to the flow of the fluid through the said nozzle, there will be produced a vacuum in the chamber 11 depending upon the speed of However, according to the size of the motor, the inducing gas could be supplied by sepa rate carlniretoi s. in this case the carburetor supplying the inducing gas is to be connected directly with the conduit 5, the communication of which is interrupted with the carburetor while the gas of the carburetor 2 or the induced gas is drawn by the pressure caused by the gas at its leaving the nozzle 9%. it evident that instead of the carburetor 2 a number of carburetors could be used so as to supply the induced gas.
Since the compression is adiabatic, the increased tcmperature oi the inducing gas will f ther the lminogcncity of the car- 'burctted mixture, and the energetic stirring caused by the injector will produce the phenomenon of turbulence which. increases the jn'opagation oi the explosive wave.
Claims: 1. A device of the kind described comprising a carburetor, an injector arranged in the feed conduit, a compressor having its suction conduit connected with the carburet- 2. A device of the kind described comprising a carburetor, an injector in the .ieed conduit, a divergent intermediary Venturi tube and a diver 'ent principal Venturi tube, a compressor having its suction conduit con- .65 the inducing gas and the induced gas.
'nected with the carburetor and its delivery conduit connected with the injector, av charm ber surroundlng the feed In eGtOr, a condult connecting the said chamber with the carburetor.
In teetlmony whereof I afllx my slgnature.
