Description

 The invention relates to a device for processing fuel-air mixtures, mainly before their inlet into internal combustion engines, and is intended for use in thermal power plants located on vehicles or stationary vehicles.

 Known devices for treating air by ionization or magnetic field before feeding it to internal combustion engines (ICE). One of these devices contains two main tubular electrodes mounted concentrically and isolated from each other, as well as at least one additional tubular electrode located concentric with the main one (see, for example, ed. St. USSR N 1590607, class F 02 M 27 / 04, 1988). This device is intended only for air treatment without affecting the fuel, which does not allow sufficiently intensify the fuel-air mixture.

 It is also known a device for treating fuel with an electric field before entering it into an internal combustion engine, comprising a hollow body with two fittings, positive and negative electrodes made of an insulating material, a body and a fuel discharge pipe (see, for example, ed. St. USSR N 1671934, class F 02 M 27/04, 1989). This device only processes the fuel without affecting the air, which also reduces the possibility of intensive combustion of the fuel-air mixture. In addition, the disadvantage of this and the aforementioned device is that the fuel and air are not exposed to mechanical forces that contribute to their better homogenization and dispersion.

 The objective of the invention is a more complete combustion of the fuel-air mixture due to the combined effects of fields and mechanical forces of various nature.

 This goal is achieved by the fact that inside the working chamber of the device and coaxially with it there is a shaft on which, with the help of elastic elements, a ring is made with the possibility of rotation and vibration, made in the form of even sectors of non-magnetic and ferromagnetic materials, alternating between themselves, on sectors of ferromagnetic the material is rigidly reinforced with spiral-shaped perforated vanes made of ferromagnetic material, and sources of constant magnetic fields with north and south poles are installed in the side walls ah working chamber pairs on opposite sides and are arranged in series on one and on the other side with respect to the normal to the shaft axis plane passing through the middle of the ring.

 In FIG. 1 shows a General view of the device; in FIG. 2 is a top view of ring 5.

 In FIG. 1, 2 the following designations are used: 1 shaft; 2 gland nut; 3 stuffing box packing; 4 blade with holes drilled in it; 5 ring; 6 spring plate; 7, 14 - sources of magnetic fields; 8, 15 pole lugs; 9 outlet pipe; sectors of the material: 10 ferromagnetic, 11 non-magnetic; 12 - tapering part of the working chamber; 13 working chamber; 16 inlet pipe.

 The device operates as follows.

 The fuel-air mixture (for example, a mixture of gasoline and air vapors obtained in the carburetor of an internal combustion engine) is supplied through the inlet pipe 15 to the working chamber 13. At the same time, a system consisting of a shaft 1, elastic elements fixed thereon, spring plates 6 is rotated. , rings 5 and blades 4. The ring and blades are rigidly interconnected and can vibrate together relative to shaft 1 due to the presence of spring plates between the latter and the ring 6. The tightness between the shaft and the working chamber is about It is provided by means of a sealing assembly comprising a nut 2 and a seal 3.

 Simultaneously with the rotation of this system, the ring 5 and the blades 4 vibrate. Vibration is achieved due to the following.

 Ring 5 consists of hard-wired sectors 10 of ferromagnetic material (for example, transformer steel) and sectors 11 of non-magnetic material (for example, bronze). Each of the pairs of sectors 10 and 11 is located opposite each other (on opposite sides of the ring 5) and they alternate with each other. When the ring 5 is rotated, it is sequentially located either by sectors 10, or by sectors 11 opposite to the pole pieces 8 and 15. In the case when the ferromagnetic sectors 10 are opposite the latter, then under the influence of magnetic fields the ring 5 is attracted to the pole pieces. With this attraction, ring 5 shifts: its upper left part to the left, and its lower right part to the right (i.e., the ring shifts counterclockwise if you look at its cross section shown in Fig. 1). The magnitude of this displacement depends on the strength of the magnetic fields emitted by the pole pieces, the mass of the ring 5 and the blades 4 rigidly connected to it, the gap between the pole pieces and the ring, as well as on the elastic forces developed by the spring plates 6.

 After the rotation of the ring 5 and the location opposite the pole tips of the sectors 11 of non-magnetic material, the ring 5 under the action of the elastic forces of the spring plate 6 returns to its original position. So when the rotation of the ring 5, it, together with the blades, is shifted by a certain angle under the action of magnetic fields, then it returns to its original position. The vibration frequency depends on the speed of rotation of the ring 5.

When passing through the working chamber 13 and its tapering part 12, the fuel-air mixture is simultaneously exposed to a complex of fields and mechanical forces:
alternating magnetic fields emitted by the blades 4. Such fields are created due to the fact that the blades are made of ferromagnetic material and are magnetized from the ferromagnetic sectors 10 with which they are rigidly connected. A change in the direction of the magnetic fields occurs due to the fact that after every 180 ^o rotation of the ring 5, the sectors and blades are under the influence of either the north or south poles of the magnets;
alternating electric fields emitted in the gaps between the blades 4. Such fields are created due to the fact that with each change in the direction of the magnetic fields this is accompanied by the appearance of induced electric fields in the gaps between the blades, each of which does not contact each other (according to the law of electromagnetic induction );
dispersing mechanical fields arising from the rotation of the blades 4 due to impacts of their planes on drops of fuel and forcing the latter through holes drilled in the blades;
centrifugal mechanical forces arising from the rotation of the blades 4, which discard the fuel-air mixture on the inner walls of the ring 5 and the narrowing part 12 of the working chamber;
excess pressure created by rotating blades 4, having a spiral shape and working as an axial type fan.

 In addition, the excess pressure developed by the blades also contributes to the improvement of engine performance by creating a certain back-up of the fuel-air mixture before it enters the cylinders.

 Due to the impact of the complex of the described fields and mechanical forces, the fuel-air mixture is intensively homogenized, chemically activated and dispersed, which contributes to its more complete combustion, increased engine efficiency, and reduced toxicity of exhaust gases.
