GAS ENGINE FACTORY "DEUTZ" in DEUTZ near COLOGNE. Innovations in gas engines.

Patented in the German Empire on August 15, 1879.

The innovations essentially consist in the working cylinders of two high-pressure gas engines, in which the force effects on the working piston only occur on every second stroke, with a third cylinder in the Way to combine the tense gases according to their action in the high-pressure cylinders alternately enter a third, the low-pressure cylinder, and continue there have an expanding effect on a piston and a common drive shaft. This becomes a Increased efficiency of the gases and a smooth running of the machine achieved.

The pistons E ₁ and E ₁ connected to the crankshaft by push rods suck a combustible mixture of air and gas into the two high-pressure cylinders C ₁ and C ₁ , FIG. On the second slope, the mixture is ignited and the work performed; on the second slope, the gases are blown out, whereupon the same game is repeated.

This mode of action of the gases in the individual working cylinders C ₁ and C ₂ is so distributed that a force is exerted on every revolution of the crankshaft, although the pistons move to and fro at the same time or almost at the same time as a result of the position of the crank pins. So if one of the pistons E ₁ and E ₁ causes the suction on a pendulum, the tension acts on the other. the gases that have just been ignited, and while one of them compresses when walking back, the other blows out the combustion gases.

Instead of letting the burnt, but still tense gases into the open, they are released through the. Valves ^ ₁ and ^ ₂ , Fig. 1 and 4, and through the countervalves z, and 4 alternately in the Niederdruckcylmder D behind the piston F connected to the crankshaft, on which the same press when going, while they press when falling "through the Outlet valve h are driven out.

During two revolutions of the crankshaft, therefore, take place in the three cylinders in the series after the following processes take place:

In the high pressure cylinder C ₁ :

1st half turn of suction,

2. - ,, .- '"* - compress,

3. - - work (high pressure),

4. - - Transfer.

In .Low pressure cylinder D:

1. blow out half a turn,

2. - - work (low pressure),

3. - - blowing out,

4. - - work (low pressure).

In the high pressure cylinder C ₁ : 1st half turn of work (high pressure),

Transfer,
Suction,
Compress.

With this arrangement, there are two forces acting on each revolution of the crankshaft, and alternately one effect with high pressure and one with low pressure, like off from the above scheme.

The transfer of the still tensioned gases from the working cylinders into the low-pressure cylinder can take place before the high pressure piston reaches its outer dead point has, the low-pressure piston on the other hand must have just reached the inner dead point.

In the space between the transition valve g _t or ^ ₂ on the one hand and the low-pressure piston on the other hand, the tension of the burnt gases at the moment of passage is kept approximately equal to the tension in the relevant high-pressure cylinder (similar to compression, in a steam cylinder) and this is achieved here by closing the discharge valve earlier and compressing the burnt residues in the low-pressure cylinder. The purpose of this compression is to relieve the transfer valves, avoid the substance when the stressed gases suddenly pass into the low-pressure cylinder and avoid the harmful space.

The counter valves 2 and 4 are located between the transfer valves g ₁ and g ₂ and the blow-out valve h; they have the purpose of the passage of the tense gases from the one

High-pressure cylinder to block the passage after the other high-pressure cylinder.

The countervalves z and L are alternately opened for compression in the low-pressure cylinder a little earlier than the relevant transfer valves gi and ^ ₂ , at the latest when the outflow valve h closes.

The movement of the two transfer valves and the two countervalves takes place by means of the connecting rod k and lever /, FIG. 4, at the end of the control shaft n, which also moves the two coupled slides O ₁ and O. The blow-out valve is moved by means of an angle lever / by the two cams q _x and q ₂ on the control shaft.

In order not to get into the Hochdruckcylindern when starting the machine to strong compression a respective Auslafsventil is down to the same, - and R ₂ is attached, which can escape the sucked mixture partially. These valves are also moved by the control crank by means of the lever /, which presses on the displaceable starting levers S ₁ and S , FIG. 4.

In order to avoid a vacuum in the low-pressure cylinder when starting, the discharge valve h, Fig. 3, is vented by the sliding starting nail t by bringing it into its innermost position so that the valve cannot go down and the piston F only atmospheric air draws in and blows out again. The whole starting device is put into action as soon as the engine is in motion. The starting levers S ₁ and S ₂ , Fig. I, and the starting nail t, Fig. 3, then have the position indicated by the dotted line.

The gas supply to the slides O ₁ and O 1, FIG. 2, the two high pressure cylinders and the regulation of the machine takes place through the gas regulation valve u, FIG. 3; the same is opened twice with one rotation of the control shaft. The two slides are under each other by a gas pipe v, Fig. 2, and the latter is connected to the valve by the pipe w, Fig. 3.

If gas with air is sucked in through one of the slides, the gas is admitted at the same time completed in the other slider.

The low pressure cylinder can be omitted and the machine is designed to a twin machine with pistons moving in the same direction, but alternating action. Even you can connect a low pressure cylinder with just one high pressure cylinder.
