In the accompanying drawing the general arrangement of the machine is shown in Figs. Fig. 7 shows the arrangement of a generator, such as the same for generating generator gases is required for machine operation. The peculiarity of the system lies in that the explosive effect of a mixture of air with fuel gas or flammable vapors is used in such a way that the strong initial pressure of the ignited mixture first is directed to a small working piston area, and then to a larger one with further expansion Piston area to come into effect.

The working cylinder A is therefore provided with an ordinary differential piston, the lower annular surface of which transfers the strong initial pressure of the exploding mixture and the upper larger surface the weaker final pressure of the expanded mixture to the crankshaft. The control of the inlet and outlet of the gases is effected by the two slides a and b , which are moved by the control disk c . The air pump D is connected to the crankshaft and has the purpose of either compressing an explosive mixture, depending on the type of operating material, or just compressing the air, which is then suitably saturated with flammable gases or vapors.

The pressed mixture, in the case of operation with coal fluorescent or generator gases, comes from the pump D through a shut-off valve n, which is controlled by the regulator F , by means of the inlet slide α to the explosion chamber C, where it is itself through a suitable flame mechanism, Fig. 1 is ignited in order to then 'exert its effect below and above the piston. The hot products of combustion either escape directly into the open air during lighting gas operation, or they are used for heating purposes.

When operating with light petroleum and similar substances, the equipment of the machine as follows:

In order to reach the ignition flames, the small gasometer g is arranged, which has the purpose of containing the gas for the flames e and i . The same thing is produced by the small air pump h pushing air through a layer soaked with naphtha, thus creating a combustible air mixture. The naphtha is fed in through a tube. On the same eccentric which sets the pump h in motion hangs the oil pump /, which has the purpose of conveying oil in very definite quantities. In the case of light oil, the same is introduced into the air pipe m by means of a pressure pipe, where it is brought into contact with the compressed air stream and is absorbed by it. The withdrawing gases enter the room G and heat you up. Line. The latter, which is arranged in the drawing as it is necessary for operation with crude oil and similar heavy oils, has the purpose in operations with medium oils to preheat the compressed air. Behind the valve η the air is after the snake from which it flows back into the line in a warmed state (Fig. 6) in order to flow through the layer impregnated with petroleum, to suck it up accordingly and to reach the explosion chamber as an explosive mixture. When operating with heavy oils, the arrangement is brought into use, as can be seen in the drawing.

The oil pump presses a certain amount of oil per revolution after the retort G into the coiled tube, which is heated by means of a burner before the machine is started.

The imported oil is depending on how it runs down, evaporated or. gassed, and finally reach the gases through the pipe q after the suction tube / pump D. To the condensation of event entrained Oeldämpfe disregard possible to '*' ■ hold, the sucked air is passed r through the tube woselbst weak preheated same will

The gas, which has to feed the two ignition flames, is taken out of the retort by means of a tube ί and the small gasometer g serves as a pressure regulator at the same time. The tube t, which is provided with a tap at the appropriate point, is used to drain the liquid residues that form from the retort every now and then. The small air pump is of course completely omitted here, as is the direct one

Claims (3)

Injection of OeI into the pipeline. Because of event. Setback, of the burning mixture from the explosion chamber are close to the inflow opening into the same wire mesh inserted. When operating with generator gases, the arrangement of the machine is almost the same as with Coal gas operation, only here the heat of the exhausting combustion products is used to to preheat air by means of a fan driven through the machine is pressed under the grate of the generator and forced into its heated state before entering under the grate. To saturate water vapor, that is a rational one Decomposition of the water thus brought through the combustion zone takes place. The general arrangement of the generator can be seen in FIG. The air, which previously passed the evaporator ν, passes through this nozzle -u into the combustion zone. The fuel layer can be seen through the rod w and the arrangement of the pouring cylinder is the usual one. The gas first enters the hydraulic system x, from where it enters the coil y in order to be passed through the theercysterne ζ to the gasometer H , from where it is used after the machine. Patent claims: ι. The peculiar exploitation of the action of an ignited explosive mixture of Air and gas or flammable vapors by using two different Pressure surfaces a uniform operation of the drive piston is achieved. 2. Use of the heat that escapes from the working cylinder Combustion products are included for heating the atmospheric required to operate gas engines Air. 3. Use of this gas engine system for stationary operation as well as for movement of transport apparatus on water and on land. For this purpose I sheet drawings.
