The invention relates to mechanical engineering, in particular to engine-building, namely to the exhaust gas silencer of an internal combustion engine, and is an improvement to the engine exhaust silencer. St. No. 1116194.

The aim of the invention is to increase the efficiency of the silencer.

The drawing shows a silencer, a longitudinal section.

The silencer contains a vortex chamber 1 with a tangential inlet w, it has a nozzle 2 connected to a mixing chamber 3, made in the form of a cylinder with a wall of porous material and equipped with a cylindrical casing 4 with a tangential nozzle 5 for supplying liquid, a discharge chamber 6, located around the mixing chamber 3 and provided with a tangential retraction w, a tube 7 by it, a guide deflector 8 located coaxially with a gap relative to the cylindrical casing 4, and a portion 9 of rotation of the vapor-gas stream of toroidal shape about developed by the end of the cylindrical housing 4 and rotating screen 10. The liquid outlet 11 is located in the lower part of the exhaust chamber 6, the rotating screen 10 is provided with an axial protrusion 12 mounted in the bearing 13 on the stationary radial ribs 14. An additional mixing junction is provided with the tangential inlet 2 chamber 15, made in the form of a truncated cone, conjugated with a large base with an additional vortex chamber 16, equipped with a gas inlet 17, mounted tangentially, and coaxially with an additional chambers 15 and 16, at their interface, install 35 liquid injector 18. Liquid to injector 18 is fed through pipe 19 passing coaxially through bottom 20 of additional swirl chamber 16.

parietal layer of the conical mixing chamber, is pressed in a swirling flow to the inlet of the tangential supply st. cutting 2. At the same time, a liquid (for example water) is sprayed from the nozzle 18, which is mixed with the hot exhaust gases. At the same time the liquid boils with the formation of steam. The steam is mixed with the gas, which contributes to an increase in the volume of the gas flow and the speed of rotation of the vortex in the tan. In this case, the swirling flow enters the vortex chamber 1, where the vortex additionally acquires movement along a helical line and is directed to the mixing chamber 3, where it is mixed with the fluid entering through the porous wall. As the gas-vapor mixture rotates in the mixing chamber not only along a helical line, but also around it, the fluid particles are pulled out in a vortex and are ejected in the radial direction (Ii direction, one hundred percent of the center of the mixing chamber 3. In this case, a finely dispersed structure is formed in the entire volume of the mixing chamber liquid droplets, which are an effective medium for noise suppression and soot deposition (adhesion on droplets of a liquid).

As soon as the mixing chamber 3, the rotating gas-vapor flow expands and decreases its speed, the liquid drops in the gas-vapor flow are thrown onto the walls of the exhaust chamber 6 by means of the section 9 of the steam-gas flow rotation. From the steaming chamber 6 of the outlet, liquid with soot particles is discharged from the outlet chamber through the branch pipe I, where the rotation of the liquid is limited by the radial ribs 14.

The soot-cleaned rotating gas flow is discharged through a channel formed by the outer wall of the cylindrical casing 4 and the wall of the deflector guide 8. The velocity of the gas flow after exiting the noise is as follows.

in a way.

The exhaust gas flow from the internal combustion engine through the tangential inlet pipe 17 enters the additional vortex chamber 16, where it swirls and, continuously rotating, is accelerated into

by increasing the radius of rotation of the flow, then increases again when entering the deflector 8, followed by a smooth slowdown and enters the upper part of the outlet chamber 6, from where the gas leaves the silencer through the tangential outlet 7,

The soot-cleaned rotating gas stream is discharged through a channel formed by the outer wall of the cylindrical casing 4 and the wall of the deflector guide 8. The velocity of the gas stream after exaggeration of the radius of rotation of the stream then increases again at the entrance of the deflector 8 with subsequent smooth deceleration and enters the top of the chamber 6, from which the gas leaves the silencer through a tangential outlet 7,
