The electrolysis chamber 13 (Fig. 2) is filled to the working level with electrolyte and contains a series of galvanically and mechanically serially connected microchambers 34 formed by electrode plates 35 arranged vertically and separated by sealed dielectric gaskets 36. The mechanical connection of the microcameras is carried out by insulating studs 37 from the electrodes between two dielectric walls.

38. Microcameras are combined into groups.

39, which are electrically connected in parallel.

All microcameras 34 and groups 39 communicate with each other. At the top of each plate electrode 35, there are gas collection holes, and at the bottom, drainage holes for electrolyte. Electrode plates 35 protrude beyond the dielectric spacers 36 to form the cooling fins of the electrolysis chamber 13. Wall 38 contains fittings 40 and 41 for supplying electrolyte and for discharging the hydrogen-oxygen gas mixture and outlets 42 for connecting sensors ov.

The optimal electrolysis process takes place when there is a certain potential UonT on each microcamera and when a certain current Iopt passes through the microcamera. For different power sources, the number of microcameras in each group

Thus, depending on the required amount of hydrogen-oxygen gas mixture, the required number of groups of microchambers in the electrolysis cell is collected.

The power supply system works as follows.

Liquid fuel, such as gasoline, from the fuel tank 1 through the fuel restriction valve 2 and the controllable fuel supply valve 3 are supplied to the carburetor 4, where it is mixed with the incoming air and sent to the combustion chamber. The fuel efficiency is significantly increased by adding to it an additional hydrogen-oxygen gas mixture enriched in liquid fuel vapor. This gas mixture is formed by the electrolysis of water and its subsequent enrichment in the mixer.

When the ignition key 20 is turned on, the power supply from the battery 24 through the included first 27 and second 29 switches is supplied to the plates-electrodes 35 of the electrolysis chamber 13. The hydrogen-oxygen mixture produced in the electrolysis chamber 13 reaches the working pressure in 30 seconds. Pressure control is carried out by the gas mixture pressure indicator 15. Through the second check valve 14, the gas mixture enters the mixer 16, made in the form of a bubbling chamber, where the gas mixture is enriched with liquid fuel vapor.

In the mixer (Fig. 3), liquid fuel vapors are formed both as a result of its evaporation and as a result of its spraying under the pressure of a mixture of hydrogen and oxygen. Progress under working pressure through a 43 h nozzle, mixer 16, filled to a certain level with liquid fuel, and passage through

About the sprayer 44, located in the lower part of the housing 45, and the fuel layer, the hydrogen-oxygen gas mixture is enriched with its vapor and accumulates in the upper part of the mixer 16 under

5 with the same working pressure, ready for feeding to the carburetor 4.

The degree of enrichment of the vapor of liquid fuel is controlled by a needle 46 overlying the jet 47 connected to the nozzle 48 of the branch of the

gas mixture. Next, the gas mixture through the gas mixture regulator 6, associated with the accelerator 7, and the safety valve 5 flows into

5, a carburettor air channel 4. Adjusting the position of the needle 46 provides a degree of enrichment of the hydrogen-oxygen gas mixture with liquid fuel vapor. Fuel is fed to the mixer.

0 16 through channel 49 through the third non-return valve 18 by pump 21 from fuel tank 1. The level of fuel in mixer 16 is monitored by sensor 19.

Maintain working pressure

jc in the electrolysis chamber 13 is carried out by the sensor 30. When the maximum working pressure is reached, the sensor 30 turns off the second switch 29 and removes power from the electrodes

electrolysis chamber 13. The electrolysis process is terminated. As the gas mixture is consumed and the pressure in the electrolysis chamber 13 is reduced to the minimum operating temperature. sensor 30 again

45 connects the power supply to the electrodes. Thus, the device maintains an operating pressure level.

With a decrease in the level of electrolyte in the electrolysis chamber 13 into it by

0, the signal of sensor 11 by pump 10 through the first non-return valve 12 is supplied electrolyte from reservoir 8. In the absence of electrolyte in tank 8, sensor 9 of electric level 9 operates

and blocks the operation of the pump 10. At the same time, the electrolyte level indicator 33 is turned on.

When the electrolyte level decreases in the electrolysis chamber 13 below the maximum allowable, the electrolyte emergency level sensor 28 is triggered and the first switch 27 turns off the power supply from the electrolysis chamber 13.

To prevent the electrode surface of the electrolysis chamber 13 from becoming contaminated with solid deposits during the electrolysis process, the polarity of the electrodes is periodically changed by polarized relay 31. Switching the relay is controlled by a pulse counter.

The system can also be used for welding and soldering ferrous and non-ferrous metals, for which an outlet valve 17 is installed for connecting a gas torch.
