Description

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

A device is known for enriching a fuel-air mixture with oxygen, comprising an air filter, a compressor, and a filter enrichment connected to the engine.

/ A.s. USSR No. 853133, F02B 51/00, 08/07/1981 / [1].

A disadvantage of the known device is cumbersome, expensive to operate and the lack of simultaneous enrichment of the air-fuel mixture with oxygen and hydrogen.

Closest to the proposed invention is an air-fuel mixture enrichment engine of an internal combustion engine, comprising an air filter and an electrolyzer connected to the engine through an air inlet pipe to enrich the air-fuel mixture. A stream of air with naturally present water or a stock of air with an aqueous electrolyte solution introduced into it passes through the electrolyzer.

/ RF patent No. 2299347, F02M 27/04, 05/20/2007 / [2].

A disadvantage of the known concentrator is the low efficiency of its electrolyzer in operation.

The technical problem solved by the invention is to simultaneously increase the efficiency of both the electrolyzer and the engine as a whole.

The problem is solved in that the device enriching the air-fuel mixture of the internal combustion engine, containing the electrolyzer body, connected by the inlet pipe to the air filter, the outlet pipe to the engine air intake pipe, the anode and the cathode, the cell body is made of a sealed cathode, for example, of a cylindrical shape and equipped with a pipe with a hermetically sealed lid for introducing an aqueous electrolyte solution into it. The inlet pipe is made with a check valve and with the possibility of supplying to the bottom of the electrolyzer a controlled, for example, a damper controlled by the engine control unit, and a gas-air filter being cleaned by the filter from a pressure source, for example, from an engine exhaust system or from a compressor. The outlet pipe is made equipped with a droplet eliminator, for example, a nozzle made of ceramic rings, and with the possibility of aspirating gases from the electrolyzer connected to the engine air inlet pipe. The anode is made in the form of a perforated cylinder concentrically with the casing from the ends fixed in it by dielectric perforated gaskets.

The invention is illustrated in the drawing.

A device for enriching an air-fuel mixture of an internal combustion engine contains an electrolyzer body 1 made of a sealed cathode, for example, of a cylindrical shape and equipped with nozzles 2 with a hermetically sealed cover 3 for introducing an aqueous electrolyte solution into the body. The inlet pipe 4, made with a check valve 5 and with the possibility of supplying to the bottom part 6 of the electrolyzer, regulated, for example, by the engine control unit, the shutter 7 and the gas gas being cleaned by the filter 8 from the pressure source, for example, from the exhaust pipe 9 of the engine 10 or from compressor / not shown /. The outlet pipe 11, made with a drip catcher 12, for example, a nozzle of ceramic rings and with the possibility of aspirating gases from the electrolyzer connected to the air inlet pipe 13 with the air filter 14 of the engine. The anode 15, made in the form of a perforated cylinder concentrically with the body, from the ends fixed in it by dielectric perforated gaskets 16.

A device that enriches the air-fuel mixture of the internal combustion engine, works as follows.

To start the device into operation through the pipe 2, an electrolyte is poured into the working cavity of the electrolyzer, for example, an aqueous solution of caustic potassium to a level that approximately half covers the horizontal section of the pipe 2, after which the pipe 2 is hermetically closed by a cover 3. Then, on the electrodes, the cathode 1, the anode 15 of the electrolyzer, for example, from an on-board battery, supply an electric current regulated, for example, set by the control unit of the engine 10, and the engine 10 is turned on. electrolyte decomposition of water into hydrogen and oxygen. In this case, the operation of the piston of the engine 10 in its air inlet pipe 13, and therefore in the electrolyzer body 1, creates a gas suction rarefaction. And in the exhaust pipe 9, on the contrary, creates an excess pressure of the exhaust gases. Due to this rarefaction and this overpressure, the exhaust gas purified by the air filter 8 and, for example, at the command of the control unit, is regulated by the damper 7 or the air, for example, from the compressor, is supplied through the inlet pipe 4 with a check valve 5 to the bottom part 6 of the cell body 1. Here, gas or air with a perforated gasket 16 breaks into small bubbles and then passes through the electrolyte level in the electrolyzer, removes and removes gas bubbles resulting from electrolysis 1 and 15, mixes with these gases and, rising upward, creates an airlift circulation of the electrolyte in electrolyzer. All this positively affects the process of decomposition of water into hydrogen and oxygen, since due to the created conditions of intensive blowing and suction of the gas mixture from the cavity of the electrolyzer, the density of the bubbles formed on the electrodes decreases, which significantly reduces the transition resistance "electrolyte-electrode", increases productivity, decreases heat and increases the safety of the cell in operation. The mixture of gases and water vapor obtained as a result of electrolysis passes through the upper perforated gasket 16, then the mixture in the drop trap 12 is cleaned of water droplets and is sucked out of the electrolyzer body 1 through the outlet pipe 11. Next, the mixture enters and mixes with atmospheric air, sucked in through the air filter 14 into the air inlet pipe 13, and is used in the engine 10 to prepare the air-fuel mixture.

The proposed device, enriching the air-fuel mixture of the internal combustion engine, significantly increases productivity, safety of the electrolyzer in operation and increases the economic, environmental efficiency of the engine as a whole. Will find wide application in engine building.
