(magazine Inventor and Rationalizer, No. 12, 2010) [2].

A disadvantage of the known enrichment is the lack of air mixing during the supply and atomization of the electrolyte into the cavity of the cathode body, which reduces the efficiency of the electrolyzer and increases the explosiveness of the gas mixture in the cathode body.

The technical problem solved by the invention is to increase the efficiency and explosion safety of the concentrator.

The problem is solved in that the enrichment of the fuel-air mixture of the internal combustion engine, comprising a cathode casing, an anode fixed in the cavity of the cathode casing by dielectric perforated inserts, a pipe-diffuser of a continuously circulating supply and atomization of an aqueous electrolyte solution by a pump from the tank into the cathode casing , the bottom part of the cathode body, an overflow pipe in communication with the tank, and its upper part, equipped with a droplet separator and air intake, cleaned from dust by an air filter that is sucked in in the upper part of the cathode casing and through the bypass pipe with a shut-off device, for example, an air damper, into the ICE air inlet pipe, a pipe for removing the gas mixture from the electrolyzer, also in communication with the engine air inlet pipe. According to the invention, the nozzle-diffuser of the continuously circulating supply and atomization of the electrolyte by the pump from the tank to the cathode body is made in the form of an ejector with the possibility of suction by it, and in the constantly circulating mode of the pump supply to the cathode body, mixed with the sprayed electrolyte from the electrolyte tank, cleaned by a filter from dust and regulated by a metering device, for example, an air damper of atmospheric air, which improves atomization, increases the efficiency of the electrolyzer and its explosion safety. In this case, the constantly circulating supply of electrolyte by the pump from the tank to the ejector is made by an adjustable metering device, for example, a crane, and an overflow tube communicating the bottom of the cathode casing with the tank is equipped with a check valve.

The invention is illustrated in the drawing.

The enrichment of the air-fuel and internal combustion engine mixture comprises a cathode casing 1, an anode 2 fixed in the cavity of the cathode casing by dielectric perforated inserts 3, an ejector 4 for continuously circulating supply and atomization of a mixture of an aqueous electrolyte solution with a pump 5 from an electrolyte tank 6 and suctioned by an ejector cleaned with a filter 7 from dust and regulated by a metering device 8, for example, an air damper, atmospheric air into the cathode casing. In this case, the constantly circulating supply of the electrolyte pump from the tank to the ejector is made by an adjustable metering device 9, for example, a crane. The enrichment agent also contains a bottom part of the cathode casing with an overflow tube 10 with a check valve 11 in communication with the electrolyte tank, an upper part of the cathode casing equipped with a bypass air inlet 12 with a shut-off device 13, for example, an air damper, from the filter 14, into the cell and into the air inlet the pipeline 15 of the engine 16, the pipe 17 for withdrawing a mixture of gases from the electrolyzer, equipped with a droplet separator 18, for example a nozzle of ceramic rings, and supplying it to the engine air inlet pipe.

The enrichment of air fuel and a mixture of internal combustion engine operates as follows.

To start the enrichment in operation, the tank 6 is charged with an electrolyte, for example, an aqueous solution of potassium hydroxide, and a constant electric current regulated, for example, by the engine control unit 16, is supplied to the electrodes of the cathode 1 and the anode 2 of the electrolyzer. an aqueous solution of electrolyte and under the control of a metering device 9, for example, a crane, and in a constantly circulating mode delivers it to the ejector 4. In the ejector 4, the energy of the working medium / electrolyte / moving at high speed is transferred to the subs yvaemoy medium / atmospheric air /. Due to this, the air cleaned from dust by the filter 7, regulated by the metering device 8, for example, an air damper, is sucked in by the ejector 4 in the required volume, which significantly improves and simplifies the operation of the entire device. In the process of ejection, the working medium — the electrolyte and the aspirated atmospheric air — is finest atomized, mixed together and in the form of a fog of the air-electrolyte mixture, from the ejector 4 enters the working cavity to the electrodes of the electrolyzer. Here, due to the flow of current through a sprayed aqueous electrolyte solution, water decomposes into hydrogen and oxygen. The resulting mixture of gases, due to the presence of air and water vapor in it, becomes completely explosion-proof when it is received in the electrolyzer and when it is supplied and used in the engine 16. Then the mixture of gases - hydrogen, oxygen, air and water vapor passes through a perforated dielectric insert 3, it is cleaned of water droplets in the droplet separator 18 and mixes with the water coming here through the pipe 12, under the control of the metering device 13, for example, an air damper, cleaned by dust from the air filter 14, which made It is obtained in the device completely non-explosive gas mixture for further use. After that, the gas mixture through the pipe 17 of the gas outlet and under the regulation of the metering device 13 approaches the air inlet pipe 15 of the engine 16 and is used in it to prepare a highly efficient air-fuel mixture. The electrolyte condensed in the bottom of the cathode housing 1, through a perforated dielectric insert 3 and through an overflow tube 10 with a 1: 1 check valve, is gravity drained into the electrolyte tank 6 and is recycled.

The proposed enrichment of the air-fuel mixture of the internal combustion engine significantly increases the economic, environmental efficiency and safety of the enrichment and the internal combustion engine as a whole.
