Description

The invention relates to mechanical engineering, in particular to air-fuel mixture enrichment devices, and can be used in engine building.

A device is known for enriching a fuel-air mixture with oxygen, comprising an air filter, a compressor, and a filter-concentrator connected to the engine with an inlet pipe (AS USSR No. 853133, F02B 51/00, 08/07/1981) [1].

A disadvantage of the known enrichment is the volume, high cost of operation 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 by an air inlet pipe for enriching the air-fuel mixture, the electrodes of which are installed in the air inlet pipe with the possibility of supplying electric current to them, and an air stream with in it in a natural way with water or an air stream with an electrolyte introduced into it (an aqueous solution of Rolita) (RF Patent No. 2299347, F02M 27/04, 05/20/2007) [2].

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

The technical problem solved by the invention is to increase the productivity of the cell.

The problem is solved in that in the enrichment of the air-fuel mixture of an internal combustion engine containing an air filter and an electrolyzer connected to the engine with an air inlet pipe to enrich the fuel-air mixture, the electrodes of which are installed in the air inlet pipe with the possibility of supplying electric current to them, and an air stream passes through the electrolyzer naturally present in it water or a stream of air introduced into it, for example, through an atomizer with an electrolyte (aqueous solution rum of the electrolyte), according to the invention, the cell body at the inlet of the air flow into it is made by a diffuser to change the speed, pressure, direction of the air flow and to increase the contact time with the electrodes, and the air flow from it is enriched with oxygen and hydrogen, it is made a confuser what increases its productivity. The electrodes of the electrolyzer to accelerate the chemical reaction can be performed equipped with a catalyst, for example, sprayed with platinum black.

The invention is illustrated in the drawing.

The enrichment device contains an air filter 1 and a device for enriching the air-fuel mixture connected to the engine 2 with an air inlet 3, made in the form of an electrolyzer 4, the housing 5 of which is provided with a diffuser 6 at the inlet of the air stream, and a confuser 7 at the outlet of the enriched air stream from it. The electrodes 8 and 9 of the electrolyzer, for example, made of nickel mesh and equipped with a catalyst, for example, sprayed with platinum black, are installed in the electrolyzer body with the possibility of supplying electric current, for example, from an onboard battery. A stream of air passes through the electrolyzer with the natural way of the water present in it with the possibility of its dissociation (decomposition of water into hydrogen and oxygen) or an air stream with an electrolyte introduced into it, for example, by nozzle 10, for example, an aqueous solution of caustic potassium.

The enrichment agent operates as follows.

To start the enrichment in work on the electrodes 8 and 9 of the electrolyzer 4, for example, an electric current is supplied from the on-board battery. The atmospheric air cleaned from dust by the air filter 1 created by the operation of the piston of the engine 2, with atmospheric water naturally present in it, or with an electrolyte introduced into it and sprayed, for example, with nozzle 10 (an aqueous solution of caustic potassium), is drawn into the electrolyzer 4. Housing 5 of the electrolyzer, at the inlet made by diffuser 6, and at the outlet of enriched air from it made by confuser 7, changes the speed, pressure, flow direction and increases the contact time of the flow with electrodes 8 and 9, which put no impact on the work of the cell. In the electrolyzer 4, due to the passage of electric current, water decomposes into hydrogen and oxygen, and the presence of a catalyst accelerates this process, while the air flow is enriched with hydrogen and oxygen, then it enters engine 2 through the air inlet pipe 3 and is used to prepare the air-fuel mixture.

The proposed enrichment significantly increases the economic and environmental efficiency of the internal combustion engine. Will find wide application in engine building.
