A multi-cyclone air purifier for an internal combustion engine comprises a rectangular housing 1 made of two identical half-molds 2 and 3, interconnected by welding or threaded connection, the side walls of which are convex outward for structural rigidity.

Support plates 4 are installed in half-forms. Separation elements 5 are installed in openings of the support plates 4 in horizontal rows, each of which is made in the form of a truncated cone-shaped cyclone 6, in which the purified air exhaust pipe 7 with scapula swirlers is partially placed 8. Separation elements 5 placed in half-shapes in such a way that they form a distribution channel 9, are combined in two blocks of 10 cyclones, each of which is placed in its half-form 2 and 3. The blocks 10 of the cyclones are restrictively threaded ties 11 located between the supporting plates 4 in the upper and lower parts of the blocks 10 of the cyclones. The restriction couplers 11 are connected to the support plates 4 by means of screws 12, and the cyclone tubes 6 installed in the support plates 4 occupy an optimal position relative to the cleaned air exhaust pipes 7 for operation of the separation elements 5. This connection with the restrictive couplers 11 ensures the efficiency and reliability of the separation elements 5, and, consequently, of the air cleaner itself. The support plates 4, in which the cyclone tubes 6 are placed, are hermetically fixed in the half-molds 2 and 3. On both sides, between the support plates 4 and the half-molds 2, 3, there is a dust collecting hopper 13, in the lower part of which a dust collecting valve 14 is installed. In the lower part of the dust collecting hoppers 13 between the walls of the half-molds 2 and 3 and the support plate 4 is a dust accumulator 15. The dust accumulator 15 additionally makes it possible to retain a significant amount thereof, with the exception of the possibility of back-casting under certain operating conditions of the air purifier into the separation elements and its penetration into the air purification system in the direction of the air filter inlet. In the lower part of the drive 15 dust passes into the pipe, on which the dust valve 14 is installed.

The exhaust air duct 16 is formed by the walls of the half-molds 2 and 3 and their support plates 4, made with a discharge pipe 17 located at the bottom for exhausting purified air. In the central upper part of the half-molds 2 and 3, opposite the cleaned air outlet pipe 17, there are curved walls 18, which help to rotate the air flow 90 ° from the top of the separation elements 5 of the cyclone blocks 10, thereby reducing the resistance and increasing the efficiency and reliability of the operation itself air purifier. On the inner surface of the half-molds 2 and 3, fixing grooves 19 are made to fix the position of the cyclone blocks 10 relative to the half-molds and to seal the support plates 4. The half-molds 2, 3 themselves are pressed through the fastening elements in the area of the fixing grooves 19 of the half-molds to the end of the plates 4 during assembly, This ensures a reliable connection "half-form - base plate".

In addition, sealing elements 20 are located in the fixing grooves 20. The sealing elements 20 ensure the tightness of the connections of the plates 4 with the half-molds 2, 3 and exclude the passage of untreated air from the inner space of the cyclone blocks 10 into the exhaust air duct 16, as well as the release of separated dust back into the block space 10 cyclones and prevent the backflow of dust into the separation elements 5, thereby increasing the reliability of the air cleaner.

For supplying untreated air to the air purifier in the half-molds 2 and 3, axial inlet pipes 21 are provided located in the upper part of the housing 1 above the distribution channel 9. In the lower part of the side walls of the half-molds 2, 3, openings 22 are made for removing atmospheric precipitation in the form of rain and, airborne dust. The air cleaner is fixed to the vehicle elements through shock absorbing elements (not shown) by means of fastening elements 23.

The air purifier operates as follows.

When the engine is running, dusty air is drawn in through the axial inlet pipes 21, passes through the distribution channel 9 organized in the central part, in which the air is evenly distributed over the organized groups of separation elements 5 of the half molds 2 and 3, and then directly between the separation elements 5. In the space between With support plates 4, the flow passes and is evenly distributed between the separation elements 5, enters the blade swirls 8 of the flow and receives rotationally screw motion in the cyclone tubes 6. Due to the centrifugal force dust particles thrown against the walls, and run in the dust hopper 13, and are accumulated in the accumulator 15 dust. Next, the air flow from the Central zone, turning 180 °, enters the tube 7 of the outlet of purified air. In this case, when the flow is turned, additional air purification from impurities also occurs. From the tubes 7, the stream of purified air enters the exhaust duct 16 and through the exhaust pipe 17 for purified air to the air filter. In this case, hitting the curved walls 18 when the air stream leaves the upper separation elements 5, the air stream rotates 90 ° from each of the blocks 10 of the cyclones in the upper part of the exhaust air duct 16, thereby accompanying a decrease in the resistance of the air cleaner. Thus, the air flows from the downstream separation elements 5 are rotated in the exhaust air duct 16 above by the generated air flow and are directed to the exhaust pipe 17 for purified air, and then to the elements of the air filtration system. When the engine is operating due to the created rarefaction of air in the dust collecting bins 13 and in the dust accumulator 15, the dust collecting valves 14 are in a closed state, the separated particles are collected and held in the dust accumulator 15. When the engine stops, the dust collecting valves 14 open, and the separated particles from the dust accumulator 15 are discharged outward, so the hopper 13 is automatically cleaned.

According to the claimed technical solution, the air purifier is reliable in operation, has a sufficiently high degree of air purification from particles suspended in the air, the design is simple, and can be mounted on the rear wall of the car cab with air intake both above and above the cab. The design of the air purifier is constructed in such a way that due to the side vertically located, opposite the central part of the blocks - distribution channel, as well as open and not blocked by cyclone tubes parts of the air exhaust pipes, inlet pipes, less resistance is provided and, thereby, the dust removal efficiency in wide range of air flow through the air purifier.

The claimed technical solution improves the reliability of the air cleaner and its effectiveness. 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, thus operating a car with this air purifier in dusty conditions, increasing the service life and service life interval for changing the main filter element of the car air purification system.

The claimed technical solution meets the requirement of industrial applicability and is possible for implementation on standard technological equipment using previously mastered technologies.
