Description

The invention relates to the field of mechanical engineering, in particular to devices for enriching a fuel-air mixture, and can be used in engine building.

A well-known internal combustion engine containing a system for preparing and supplying a lean air-fuel mixture to a cylinder and a system for separately supplying hydrogen to a cylinder is used to enrich the working mixture in a cylinder and increase engine economic efficiency (see RF patent No. 1329273, publ. 01.20.1997).

A disadvantage of the known engine is complexity, cumbersome due to the presence of two systems for supplying two types of fuel. Including hydrogen from a cylinder. The lack of enrichment of the air-fuel mixture with oxygen.

Closest to the proposed invention is a device for enriching the air-fuel mixture with oxygen, containing an air filter, a compressor and a filter-enrichment connected to the engine through an air inlet pipe (see AS USSR No. 853133, publ. 07.08.1981).

The disadvantages of the known enrichment are cumbersome, expensive to operate and the lack of simultaneous enrichment of the air-fuel mixture with hydrogen and oxygen.

The technical problem solved by the invention is to increase the efficiency of the internal combustion engine due to the simultaneous enrichment of the air-fuel mixture with oxygen and hydrogen.

The stated technical problem is solved in that in the enrichment of the air-fuel mixture of the internal combustion engine containing the air filter and the device for enriching the air-fuel mixture connected to the engine by the air inlet pipe, according to the invention, the device for enriching the air-fuel mixture is made in the form of an electrolyzer, the electrodes of which are installed in the air inlet pipe, with the possibility of supplying electric current to them, moreover, an air stream with the present in it passes through the electrolyzer stestvennym by water or air stream with an electrolyte inserted therein (aqueous electrolyte solution).

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. Electrodes 5 and 6 of the electrolyzer, for example, made of nickel mesh, are installed in the air inlet 3, with the possibility of supplying electric current, for example, supplied from the on-board battery 8. Through the electrolyzer 4, an air stream freely flows with the water present in it with the possibility of its dissociation (decomposition of water into hydrogen and oxygen Orod) or air flow introduced into its flow, e.g., a nozzle 7, an electrolyte (an aqueous electrolyte solution).

The enrichment agent operates as follows.

Before starting the enrichment in work on the electrodes 5 and 6 of the electrolyzer 4, for example from the on-board battery 8, an electric current is supplied. The atmospheric air created by the work of the piston of the engine 2, cleaned from dust by the filter 1, is sucked into the electrolyzer 4 through the air inlet pipe 3. The air stream with water naturally present in it or with electrolyte introduced into it and sprayed, for example, with nozzle 7 (water solution) potassium hydroxide) freely passes through the electrodes 5 and 6 of the electrolyzer 4. In the electrolyzer 4 due to the passage of electric current, for example, supplied from the battery 8, water decomposes into hydrogen and oxygen, while the air flow enriched with hydrogen and oxygen. Enriched in the electrolyzer 4 with hydrogen and oxygen, the air through the air inlet pipe 3 enters the engine 2 and is used to prepare the air-fuel mixture.

The proposed enrichment at the same time enriches the air-fuel mixture with hydrogen and oxygen, which significantly increases the economic and environmental efficiency of the internal combustion engine. The enrichment will find application in engine building.
