As a result of the analysis of the prior art on patents and other sources of scientific and technical information, an analogue characterized by features identical to all the essential features of the claimed technical solution was not found. Therefore, the proposed technical solution meets the condition of patentability "novelty."

A multi-cyclone air purifier for an internal combustion engine comprises a housing 1 made of two identical half forms 2 and 3, interconnected along a longitudinal line by welding or screws. The side walls of the half-molds 2 and 3 are made convex at the edges and concave inward in the middle part.

Support plates 4 are installed in the housing 1, in the openings of which separation elements are installed in horizontal rows on the basis of bladed swirls of air flow, each of which is made in the form of a truncated conical cyclone tube 5, into which the purified air exhaust pipe 6 with bladed swirls 7 is partially placed The separation elements are combined into two blocks of 8 cyclones, each of which is placed between the half-molds 2 and 3 and is fixed from movement by the sealing elements of the blocks of 8 cyclones located on interior surfaces of half-forms.

The exhaust air duct 9 is formed by the side walls of the half-molds and supporting plates 4 and is made with a pipe 10 located in the lower part for the removal of purified air. The side walls of the half-molds 2 and 3 in the area of the air duct 9 are made concave inward, form guide surfaces in the air duct, which ensures a decrease in resistance and the direction of air flow towards the nozzle 10.

Along the side walls of each of the half-molds 2 and 3 opposite the open and non-overlapping cyclone tubes 5 parts of the air exhaust tubes 6, inlet openings 11 are made, which are arranged vertically to evenly distribute the air flow to horizontally positioned cyclones. This arrangement of the inlet openings 11 reduces the possibility of atmospheric precipitation falling into the air cleaner and snow sticking, blocking the inlet of the air cleaner.

Dust collecting bins 12 are formed from the ends by the side walls of the half-molds 2 and 3 and the nearest supporting plate 4, have a nozzle in the lower part and are equipped with an automatic dust-collecting valve 13 for dust discharge when the engine is stopped.

The blocks 8 of the cyclones are equipped with a retaining partition 14 with rod mounting tips for fastening with screws. The partition 14 divides the inner space of the air purifier in the area of each block of 8 cyclones into two compartments 15 and is installed in the vertical direction, which eliminates harmful turbulence and shock from oncoming flows when air is supplied to horizontally located cyclones.

Holes 16 are made in the lower part of the side walls of the half-molds to remove atmospheric precipitation in the form of rain and dust.

To prevent foreign objects from entering the air purifier with air, the inlet openings 11 are equipped with grilles 17.

The air purifier operates as follows.

When the engine is running, dusty air is drawn in through the inlet 11, then it is distributed over the compartments 15 of the air purifier units 8. In the space between the support plates 4, the flow passes and is evenly distributed between the separation elements, flows to the scapular swirlers 7 of the flow and receives a rotational screw motion in the cyclone tubes 5. Due to the action of centrifugal force, dust particles are thrown to the walls and are driven into dust collecting bins 12. Next, the flow air from the Central zone, turning 180 °, enters the tube 6 of the outlet of purified air. In this case, when the flow is turned, additional air purification from impurities also occurs. From the tubes 6, the cleaned air enters the exhaust duct 9 and then to the air filter.

When the engine is operating due to rarefaction in the dust collecting bins 12, the nipple valves 13 are in a closed state and separated particles are collected in them. When the engine stops, the nipple valves 13 open, and the separated particles spill out, so the hopper 12 is automatically cleaned.

The air purifier according to the claimed technical solution has a sufficiently high degree of air purification from particles suspended in the air, the design is simple, it can be mounted on a car, for example, on the rear wall of the car cab. The design of the air purifier is constructed in such a way that due to the lateral vertically opposite parts of the inlet air ducts that are open and not blocked by cyclone tubes, as well as due to the vertical partitions and the side walls being concave, less resistance is provided and dust removal efficiency is improved over a wide flow range air through the air purifier.

The claimed technical solution also allows to increase the reliability of the air purifier and its efficiency due to the execution of the walls of the housing in a certain way molded and convex outward and inward, reducing the resistance of the air purifier, reducing the ingress of atmospheric precipitation into the air purifier and the sticking of snow blocking the entrance to the air purifier. In addition, this solution, while maintaining a compact design, its aesthetics, as well as the manufacturability of the product, will improve the main indicators of the internal combustion engine and the characteristics of the vehicle as a whole, operate a car with this air purifier in dusty conditions, increase the resource and the service interval for changing the main filter element car air purification systems.

The technical solution meets the requirements of industrial applicability and is possible for implementation on standard processing equipment.
