Abstract

The invention makes it possible to reduce fuel consumption and exhaust emissions. The intake air is fed into the gap between the electrodes 3 and 5, the first of which is made in the form of a grid, and the second is in the form of a metal plate covered with a continuous layer of electrical equipment 6. Fuel, not mixed with air, is supplied from the nozzle 7 to the surface of the dielectric 6 and it is under the influence of email. the floor spreads on it in the form of a liquid film 8. In the interelectrode gap, a layer 9 of ionized medium is formed, which varies with the frequency of the output voltage of the high-voltage source 1, causing ultrasonic vibrations in the flow. Under the influence of these fluctuations, and changing e-pol. the film fuel evaporates and its vapors are intensively mixed with the ionized medium. Forming a fuel-air mixture has a completely evaporated fuel and a partially ionized medium, the combustion takes place with great efficiency. 1 il. S (l

This invention relates to mechanical engineering, in particular, to methods for preparing a fuel-air mixture in an internal combustion engine.

The aim of the invention is to reduce fuel consumption and exhaust gas toxicity.

The drawing shows the device DP preparation of the air-fuel mixture in the internal combustion engine of the implementation of the proposed method.

The device contains a high-voltage alternating voltage source 1, the output 2 of which is connected to the electrode 3, made in the form of a grid, and the output 4 - to the electrode 5, made in the form of a metal plate, covered with a continuous layer of the dielectric 6o. with a source of liquid fuel (not shown).

The proposed method of preparing the air-fuel mixture is carried out as follows.

When the engine is in operation, air is sucked into the last air into the gap by electrodes 3 and 5, and fuel not mixed with vzdukh is supplied from nozzle 7 to the surface of dielectric 6 on which, under the influence of an electric field, this fuel spreads in the form of a liquid film 8, an electric field ionize in the gap, resulting in the formation of an ionized layer 9 of the medium, which oscillates with the frequency of the output

spraying source I, causing ultrasonic oscillations in the stream passing through the electrode gap. These vibrations, together with the varying electric field, vaporize the fuel from the film, and the fuel vapors are intensively mixed with the ionized medium, which moves in the interelectrode gap, so that the air-fuel mixture, the fully evaporated fuel, and the partially ionized medium form at the output of the device. Combustion of such a mixture occurs with great efficiency, reducing fuel consumption, and the engine exhaust gases have less toxicity. Invention Formula The method of preparing the air-fuel mixture in an internal combustion engine by passing a stream in a variable electric field between two electrodes, one of which is made in the form of a grid, so that, in order to reduce the flow rate fuel and exhaust emissions, air is passed into the gap between the electrodes, and fuel, not mixed with air, is supplied to the surface of another electrode covered with a continuous dielectric layer, with the formation of a liquid film on it, in the interelectrode gap, ionize the air and The ionized medium is excited by ultrasonic vibrations of the vaporization of the film of fuel, and its resulting vapors are mixed with the ionized medium.
