Description

The technical solution relates to the field of mechanical engineering and, in particular, to an exhaust gas neutralization device for an internal combustion engine.

Known liquid neutralizer exhaust gases of the internal combustion engine, containing the housing, partially filled with liquid, with inlet and exhaust manifolds.

The disadvantages of this device are;

1) when the engine is running at low speed, the liquid will fill the gas channel and the gas will pass through bubbles, which will drastically reduce the gas cleaning efficiency and may cause the engine to stop;

2) engine power decreases, as gas must pass through a layer of fluid;

3) the device ensures normal operation only with stable parameters of the engine.

A known exhaust system for an internal combustion engine comprising a liquid neutralizer, a pump, a valve, a radiator, a fan, and piping.

The disadvantages of this device are:

1) forced return of fluid;

2) when the pump is driven by an engine, the design of the driver is complicated;

3) when the pump is autonomous, there is a difficulty in regulating the supply of a certain amount of water with changes in engine operation parameters.

It is also known a device for the disposal of exhaust gases of an internal combustion engine (AS USSR No. 757751, F 01 N 3/04, 1978), comprising a sequential case with a neutralizer and a liquid Venturi scrubber, a tank with neutralizing liquid.

The disadvantages of this device are:

1) the complexity of the design and operation;

2) the neutralizing liquid circuit is forced;

3) is suitable only when working at the hospital, with constant parameters of the engine.

The aim of the technical solution is to increase the efficiency of the device due to the intensive mixing of gas with neutralizing liquid and the self-regulation of the process of supplying neutralizing liquid. Dependence on changes in the parameters of the engine.

This goal is achieved by the fact that the neutralizer is made in the form of 2 blocks and contains an inlet pipe passing through the first block and communicating with the exhaust manifold of the engine for the exhaust gas inlet, the displacement assembly is made in the form of a T-shaped inlet pipe and a liquid inlet pipe . On the inlet pipe, inside the first block, b

at the point of attachment of the liquid supply pipe, an auxiliary pipe is mounted, at an angle in it, which enters at one end into the inlet pipe, and at the second end goes inside the first block. In addition, the device contains a second block that is connected in the upper part with the first block inlet pipe, and in the lower part - by a suction pipe, at one end of which

an elastic element placed in the first block is installed, preventing the flow of neutralizing liquid from the first block into the second one. At the end of the inlet pipe placed on the second block, an additional elastic element is installed. The second unit has an outlet on which the catalytic unit is mounted. In the upper protruding part of the second block, there are mounted drop-breaking plates,

perpendicular to each other.

Distinctive features of the technical solution are: the suction pipeline, the first block is designed as

an additional tank communicated with the main tank by means of a suction pipe, at one end of which, placed in the first block, an elastic element is installed, the main tank is made with a volume exceeding the volume of the additional tank. The inlet pipe is made with a constant cross section, at the second end of which an additional elastic element is installed, and the auxiliary pipe is fixed on the inlet pipe, at the place of its connection with the liquid inlet pipe .;

The technical solution meets the criterion of novelty because has a different set of features.

The technical solution meets the criterion of significant differences because has features that do not coincide with the properties of features known technical

making.

FIG. 1 shows a general view of the device; in fig. 2 - the location of the device in the car; in fig. 3 - the device of the elastic element.

 The neutralizer contains the first unit 1. in which the displacement unit 2, consisting of the inlet pipe 3, the first end 4 of which is connected to the exhaust manifold of the engines and the liquid supply pipe 5, is placed, an auxiliary pipe 6 at an angle to the inlet is mounted on the inlet pipe 3 the pipe at the point of connection of the liquid supply pipe and enters one end of the cavity of block 1 and the other end of the inlet 3, the second block 7 in the upper part is connected to the first block by means of an inlet 3 an additional elastic element 8 is assembled from an elastic plate, and an elastic element 10 is mounted in the lower part of the suction pipe 9, preventing the movement of the neutralizing fluid from block 1 to block 7, made in the form of a flat ring 11 fixed at an angle to the end of the suction pipe 9 , elastic plate 12, reinforced by the upper end. The second unit 7, above the inlet nozzle inlet 3, has an outlet pipe 13 on which the catalytic unit 14 is mounted, inside the protruding part of the second unit 7, a drip catcher 15 is mounted, consisting of drip plates installed perpendicularly one to the other. The first block 1 has a drain pipe 16, the second block 7 has a drain pipe 17 and a pipe 18, for pouring neutralizing liquid into the device.

The device is housed in a car trunk 19 and is connected to an intake manifold of the engine via an inlet pipe. The device is installed across the longitudinal axis of the car in order to reduce the turbulence of the neutralizing fluid during its movement.

The device works as follows.

The device is installed in the boot of the car 19, is partially filled with a neutralizing liquid and connected by the inlet 4 to the exhaust manifold. The engine exhaust gas enters through the inlet pipe 3 to the displacement unit 2, the movement of the exhaust gas is separated, a part through the auxiliary pipe 6 enters into the interior of the unit 1, the second part moves through the inlet pipe. A part of the gas entering the inside of the block 1 creates pressure in it which presses on the working fluid and it enters the inlet manifold 3 through the liquid supply nozzle 5, which is picked up by the gas flow, neutralizing the liquid during

This is sprayed and intensively mixed with the gas stream (as a neutralizing liquid, for example, water can be).

The movement of the fluid through the pipe supply fluid 5 and its dispersion contributes to the ejection; formed after the auxiliary pipe 6. Moving through pipe 3, the exhaust gas is neutralized with a neutralizing mist and enters the second block 7. The additional elastic element 8, in the form of an elastic plate, directs the gas-liquid mixture downward to improve the conditions for separating the liquid with gas. It is more efficient to operate the whole device at low engine speeds, by covering the outlet opening of the inlet pipe 3. Part of the gas will flow through the auxiliary pipe 6 into unit 1 and will contribute fluid lift. The reflector is arranged in a similarity to a device that prevents liquid from overflowing from block 1 to block 7. The purified gas through the trap 15, where it is cleaned of neutralizing liquid, enters the exhaust line 13, then into the catalyst block 14, where carbon monoxide is the most harmful part of the gas is converted to carbon dioxide and goes outside. The installation of the catalyst unit s at the end of the process prevents the catalyst from clogging up; which improves gas cleaning efficiency (as a catalyst, for example, manganese dioxide can be).

Neutralizing fluid by increasing the volume of block 7, as compared with the volume of the inlet pipe and sharply reducing the flow rate of the mixture, precipitates vigorously in block 7 and re-enters unit 1 through the suction line 9 due to the increase in the level of fluid in block 7 and lowering in the block 1, in addition, the exhaust pipe 13 has a diameter smaller than the inlet pipe 3, to create additional pressure in block 7, which will contribute to the overflow of fluid from block 7 to block 1. The smaller diameter is from 0.25 to 0.75 of the inlet diameter The second nozzle 3 has an auxiliary nozzle 6, a nozzle for supplying liquid 5 and an exhaust pipe 13. The elastic plate 12. fixed at one end on the ring 11, which is mounted on the end of the suction pipe 9 at an angle, prevents the movement of the neutralizing liquid from block 1 to block 7, freely passes it in the opposite direction, so there is a circulation of neutralizing liquid in the device. As the fluid is greased, it is drained through nozzles 16 and 17. Fluid flow occurs through nozzle 18. The device operates on the principle of self-regulation, the higher the engine speed, the more intense the process of supplying fluid to the displacement unit, and hence the degree of gas purification.
