Known solutions in most cases have insufficient reliability and cleaning efficiency, due to the fact that they cover the dirty air area, in addition, there is no water separator and dirt trap, which reduces cleaning.

The task to which the claimed technical solution is directed is to increase the efficiency of the air intake and cleaning of moisture that has entered the inside.

The problem is solved in that the air intake for the internal combustion engine, made in the form of an air duct, on the one hand communicating with the air filter, and on the other hand equipped with inlet windows, brought up on the car, the axis of which is located in a horizontal position, dumping device in the form of a nipple valves, we will communicate with the atmosphere, as well as the upper outer wall, straight horizontal sections and a vertical section located after the inlet windows, the atmospheric moisture separator from the fluid with the accumulator and the drain hole, additionally contains air pre-treatment units with separation elements based on both sides direct-flow cyclones, including cyclone tubes, flow swirls, cleaned air exhaust tubes, while the cyclone tubes have a notch, pre-treatment units have guide walls, and the water separator contains a divider, in addition, the upper outer wall is made and bent along the radius, and the vertical section is made of elliptical section step-grooved.

The air intake for the internal combustion engine is made in the form of an air duct containing on one side an outlet pipe 1 communicating with an air filter, and on the other hand provided with two inlet windows 2 and 3. Moreover, on the air intake, the upper outer wall 4 is made radially curved, which eliminates the possibility of turbulence of the air flow in this area, thereby increasing the flow resistance and ensuring the efficiency of the air intake. Entrance windows 2 and 3 are located opposite each other and brought up on the car, while the axis of the windows is located in a horizontal position. The inlet windows 2 and 3 have openings 5. The air intake also includes a discharge device 6, made in the form of a nipple valve communicating with the atmosphere and located in the lower part of the pipe 7. After the inlet windows 2 and 3, the air inlet has straight horizontal sections 8 and vertical section 9 made of elliptical cross section step-grooved. In front of the outlet pipe 1, a atmospheric moisture separator is made from the fluid, which contains a divider 10, designed to trap and disperse the water or moisture that has got inside, a reservoir 11 and a drain hole 12. In this case, the divider 10 allows you to get local disturbance of the fluid flow and direct the ingress of water or moisture from the atmosphere to the drive 11, thereby increasing the efficiency of the air intake. The air intake also contains, on both sides, air pre-purification units 13 with direct-flow cyclone separation elements 14, including cyclone tubes 15, cleaned air exhaust tubes 16 mounted coaxially to the cyclone tubes 15. The cyclone tubes 15 are made with flow swirlers 17 installed therein and a cut-out 18, which is designed to discharge the dust that has got inside, increasing work efficiency. The pre-treatment blocks 13 have guide walls 19, which increase the efficiency of work by protecting contaminated particles from entering the cyclone tubes 15. The pre-cleaning blocks 13 are connected to the straight horizontal sections 8 by an overlap and are fixed with fasteners 20. For connecting the air intake to the vehicle fasteners 21 and 22, made in the form of holes in the upper and lower parts of the air intake.

Thus, the claimed air intake allows to increase the cleaning efficiency through the use of direct-flow cyclones, in which there are cutouts 18 and guide walls 19, which exclude the re-capture of particles by air flows from the atmosphere of neighboring cyclones, which contributes to the reliable movement of the separated particles in the direction of the pipe 7, on which a reset device 6 is installed, in addition, the use of direct-flow cyclones allows to reduce the resistance of the system, thereby increasing the efficiency of the air intake.

The air intake works as follows. Atmospheric air is drawn in during operation of the internal combustion engine through the inlet windows 2 and 3, entering the separation elements 14, where it is unwound by swirls 17 of the flow installed in the cyclone tubes 15. Mechanical particles are discarded by centrifugal force through the cutout 18 in the cyclone tubes 15, and then move into the space of the preliminary cleaning unit 13 of the separation elements 14 in the direction of the nozzle 7 and the discharge device 6. The cleaned air is directed through the purified air exhaust pipe 16 into the air cleaner towards the outlet pipe 1. In the presence of precipitation in the air and passing through the preliminary cleaning unit 13 of the separation elements 14, precipitation in the form of water or moisture is deposited on the inner walls of the air purifier, due to the step-grooved surface, turbulence of the near-wall flow contributes to the deposition of sediments. Water or moisture contained in the air stream and flowing down the inner walls of the casing enters the divider 10 and flows through it into the accumulator 11 and is discharged through the openings 12. When the internal combustion engine stops, the discharge device 6 opens and mechanical particles are removed from the block 13 preliminary cleaning, and the presence of the guide walls 19 prevents the separated mechanical particles from entering the upper separating elements of the preliminary cleaning unit 13 into the fluid flows when moving to the pipe 7, thereby ensuring air purification and increasing the efficiency of the air intake.

The claimed technical solution improves the efficiency of the air intake. 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.
