Description

The invention relates to engine building, in particular to devices enriching the air-fuel mixture, and can be used in internal combustion engines.

Known enrichment of the air-fuel mixture of an internal combustion engine, containing an air filter and an electrolyzer connected to the engine through an air inlet pipe for enriching the air-fuel mixture. Where through the electrolyzer passes a stream of air with naturally present water or a stream of air with an aqueous solution of electrolyte introduced into it (RF Patent No. 2299347, publ. 05.20.2007).

A disadvantage of the known enrichment is the low productivity of its cell.

Closest to the proposed invention is a device for enriching the air-fuel mixture of an internal combustion engine, comprising a cathode, an anode fixed in the cathode cavity with dielectric perforated gaskets, a diffuser nozzle for supplying through it into the cathode cavity a pump of an aqueous electrolyte solution from an electrolyte tank and air purified by a filter and regulated by a metering device, the outlet pipe equipped with a droplet separator and the bottom of the cathode, an overflow pipe with a check valve with an electrolyte tank (RF Patent No. 2405960, publ. 10.12.2010) (prototype).

A disadvantage of the known enrichment is a low-efficient and complex system for supplying air to the device.

The technical problem solved by the invention is to increase the efficiency of intake of atmospheric air into the electrolyzer while simplifying the design of the device.

The problem is solved in that in the enrichment of the ICE fuel-air mixture containing the cathode, the anode is fixed in the cathode cavity with perforated dielectric inserts, the diffuser pipe feeds through it into the cathode cavity an electrolyte pump from the tank and atmospheric air, cleaned from dust by a filter and regulated by a metering device for example, an air damper, an outlet pipe provided with a droplet separator, for example a nozzle made of ceramic rings, and connected to the engine air inlet pipe, and the bottom h st cathode cavity, an overflow pipe with a check valve communicating with the electrolyte tank.

According to the invention, the nozzle-diffuser of the feed through it into the cathode cavity by a pump of an aqueous electrolyte solution from the tank and atmospheric air, cleaned from dust by a filter and regulated by a metering device, is made in the form of an ejector with the possibility of suction by it, and in a constantly circulating mode of pump supply into the cathode cavity in mixtures with atomized electrolyte from an electrolyte tank and cleaned of dust from the filter and regulated by a metering device, for example, an air damper, of atmospheric air. In this case, the constantly circulating pump feed of an aqueous solution of electrolyte from the tank to the ejector is made by an adjustable metering device, for example, a crane.

The invention is illustrated in the drawing.

The ICE fuel-air mixture enricher contains a cathode 1, anode 2, fixed in the cathode cavity with perforated dielectric inserts 3. An ejector 4 for constantly circulating supply and atomization of an aqueous solution of an electrolyte with a pump 5 from an electrolyte tank 6 and suctioned by an ejector 4 that has been cleaned by the filter 7 from dust and is controlled by the metering a device 8, for example, an air damper, atmospheric air into the cavity of the cathode 1. In this case, the supply of electrolyte pump 5 from the tank 6 to the ejector 4 is made adjustable by metering devices ohm 9, for example by crane. The bottom of the cavity of the cathode 1, an overflow tube 10 with a check valve 11 in communication with the electrolyte tank. The outlet pipe 12, equipped with a droplet separator 13 for outputting the gas mixture from the cavity of the cell through the droplet separator 13 and in communication with the air inlet pipe 14 for supplying the gas mixture to the engine 15.

The enrichment of the engine air-fuel mixture is 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 current, regulated, for example, by the engine control unit 15, is supplied to the electrodes of the cathode 1, anode 2 of the electrolyzer. Then, a pump 5 is turned on, which takes an aqueous solution of electrolyte from the electrolyte tank 6 and, under the control of a metering device 9, for example, a crane, and in a constantly circulating mode supplies it to the ejector 4. In the ejector 4, the energy of the working medium (electrolyte) moving with a large speed, transmitted to the sucked-in medium (atmospheric air). Due to this, the air cleaned from dust by the filter 7 and 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 device. In the process of ejection, the working medium-electrolyte and atmospheric air sucked in by the ejector 4 are sprayed finest, mixed together and in the form of fog of the air-electrolyte mixture from the ejector 4 enter the working cavity to the electrodes of the electrolyzer. Where due to the flow of current through the atomized electrolyte there is an intensive decomposition of water into hydrogen and oxygen. The resulting gas mixture due to the presence of air and water vapor in it becomes absolutely explosion-proof when it is received in the electrolyzer, and when it is subsequently used in the internal combustion engine. Then the mixture of gases - hydrogen, oxygen, air and water vapor passes through the perforated dielectric insert 3, is cleaned of electrolyte droplets in the droplet separator 13 and through the outlet pipe 12 enters the air inlet pipe 14 of the engine 15 and is used to prepare a highly efficient air-fuel mixture. The electrolyte condensed in the bottom of the cavity of the cathode 1 through a perforated dielectric insert 3 and through an overflow pipe 10 with a check valve 11 is gravity drained into the electrolyte tank 6 and reused.

The proposed ICE fuel-air mixture enrichment significantly increases productivity, explosion safety, efficiency, electrolyzer and, as a result, the efficiency of the internal combustion engine.
