A disadvantage of the known technical solution is the uneven distribution of air over cyclones and a decrease in the efficiency of air purification, in addition, the increased local resistance of the device affects the decrease in the performance of the internal combustion engine, and as a result, the deterioration of the vehicle.

The task to which the claimed technical solution is directed is to increase the efficiency of the air purifier while maintaining its compact design, aesthetics, as well as the manufacturability of its manufacture.

To solve the problem in a multi-cyclone air purifier for an internal combustion engine containing a rectangular housing, on the upper base of which there is a lid, forming a cavity for purified air, with a discharge pipe fixed to it, the side walls are made with the possibility of air intake, and the upper and lower bases are made with holes in which respectively installed pipes for the removal of purified air with flow swirls and cyclone tubes, a dust collector, side walls are made the input windows which are placed in front of the blade and provided with flow swirlers gratings, wherein the bottom of the side walls are provided with holes for removing water and dust, and a dust hopper comprises uncoupling partition to form compartments.

In addition, the holes of the upper and lower bases of the housing are staggered, and the dust hopper is equipped with a nipple valve.

The combination of distinctive features, namely, that the side walls are made with inlet windows, which are located opposite the entrance to the scapular flow swirls and are equipped with gratings, while in the lower part of the side walls holes are made to remove water and dust, and the dust collecting hopper contains a disconnecting partition for the formation of compartments, allows to improve the quality of purified air, and thereby increase the efficiency of the air purifier.

As a result of a search conducted on patent and other scientific and technical literature, no analogue was found that coincided with the claimed technical solution for the entire set of essential features. Therefore, the claimed technical solution meets the condition of "novelty."

The claimed technical solution is illustrated by drawings, which depict:

FIG. 1 - multicyclone air purifier for an internal combustion engine, front view;

FIG. 2 is the same, a longitudinal sectional view of the air cleaner across the axes of the cyclones;

FIG. 3 is the same, cross-sectional view of the air cleaner along the axes of the cyclones (enlarged image).

A multi-cyclone air purifier for an internal combustion engine comprises a rectangular housing 1 made with a lower base 2, an upper base 3, on which a cover 4 is mounted with a discharge pipe 5 fixed to it, separation elements 6 including cyclone tubes 7, vane swirlers 8 of a flow with tubes 9 for the removal of purified air, dust hopper 10.

The housing 1 is made in a box-shaped form with an open upper part, includes one side, end walls made at the same time, while two of its side walls are made with the possibility of air intake through the inlet 11 located opposite the entrance to the blade vortexes 8 of the stream. The upper and lower bases 2 and 3 are made with holes 12 staggered in four rows, in which tubes 9 for purifying air and cyclone tubes 7 are installed respectively. The cover 4 has a dome shape, is mounted on the upper base 3 and forms a cavity for direction purified air. Holes 13 are made in the lower part of the side walls to remove water and / or dust. To prevent ingress of foreign objects into the air cleaner along with air, the inlet windows 11 are equipped with gratings 14.

The dust hopper 10 includes a disconnecting partition 15 for the formation of compartments 16, each of which is equipped with a nipple valve 17 for automatic dust discharge when the engine is stopped.

Inside the housing 1, mounting brackets 18 are provided for mounting the air cleaner to the vehicle.

The air purifier operates as follows.

When the engine is running, the dusty air stream is drawn in through the inlet windows 11 with grilles 14, passes into the inner space of the air cleaner and is evenly distributed between the separation elements 6. When the air stream enters the swirls 8, it receives a rotational screw motion in the cyclone tubes 7. Due to the action of centrifugal forces of the dust particle are thrown to the walls and are driven into the compartments 16 of the dust collecting hopper 10. Then, the air flow from the central zone, turning 180 °, enters the cleaning pipes 9 a lot of air. In this case, when the flow is turned, additional air purification from impurities also occurs. From the tubes 9, the cleaned air enters the interior of the lid 4 and then passes through the outlet pipe 5 to the air filter. When the engine is operating due to rarefaction in the hopper 10, the nipple valves 17 are in a closed state, separated particles are collected in them. When the engine stops, the nipple valves 17 open and the separated particles spill out, so the hopper 10 is automatically cleaned.

According to the claimed technical solution, the air purifier has a sufficiently high degree of air purification from particles suspended in the air, by its simple design, it can be mounted on a truck, for example, on the rear wall of the cab. The design of the air purifier is designed in such a way that due to the lateral horizontally located inlet windows located opposite the parts of the air exhaust pipes that are open and not blocked by cyclone tubes, less resistance is provided and dust removal efficiency is increased in a wide range of air flow through the air purifier.

The claimed technical solution allows to increase the efficiency of the air cleaner, reduce the local resistance of the device. In addition, this solution, while maintaining a compact design and product aesthetics, as well as manufacturability, improves the main indicators of the internal combustion engine and the characteristics of the vehicle as a whole, makes it possible to operate the car in dusty conditions, to increase the resource and service interval for changing the main filter element of the cleaning system car air.
