The task to which the claimed technical solution is directed is to increase the efficiency of air purification from impurities.

The problem is solved in that a multicyclone air cleaner for an internal combustion engine, comprising a rectangular housing, on the upper base of which there is a lid, forming a cavity for air purification, with a discharge pipe fixed to it, upper and lower bases made with holes in which are installed respectively cleaned air discharge tubes with flow swirls and cyclone tubes, a dust collecting hopper containing a disconnecting partition to form compartments, and provided with a nip valve, side walls made with the possibility of air intake, inlet windows, which are located opposite the entrance to the scapular flow swirls and are equipped with gratings, and holes for removing water and dust, made in the lower part of the side walls, additionally have a longitudinal partition located in the housing at the upper base between the separation elements, mounted on the opposite side relative to the cover, and directed to the lower base.

An analysis of the known technical solutions, carried out according to scientific, technical and patent documentation, showed that the set of essential features of the claimed technical solution is not known from the prior art, therefore, it meets the patentability condition of the utility model “novelty”.

The utility model is illustrated by the following drawings:

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

FIG. 2 - same, right view, enlarged image;

FIG. 3 is the same, cross-sectional view of the air purifier along the axes of the cyclones, an enlarged image.

A multi-cyclone air purifier for an internal combustion engine contains a rectangular housing 1, separation elements 2, including cyclone tubes 3, vane swirlers 4 flows with tubes 5 for the removal of purified air, a dust collecting hopper 6. Housing 1 is made in a box shape with an open upper part, with a lower base 7 and the upper base 8, on which the cover 9 is mounted with the outlet pipe 10 mounted on it. The housing 1 includes integral lateral, end walls, and two side walls thereof filled with the possibility of air intake through the inlet windows 11, which are located opposite the entrance to the blade vortexes 4 of the stream. The upper base 7 and the lower base 8 are made with holes 12, which are staggered in four rows. They have cleaned air exhaust pipes 5 and cyclone tubes 3. The upper base 8 of the housing 1 is equipped with a vertical longitudinal partition 13 of a certain height, which is directed to the lower base 7 and is fixed at the upper base 8 between the separation elements 2 from the opposite side relative to the cover 9. The longitudinal partition 13 is designed to reduce resistance from possible interaction of oncoming air flows supplied to the air purifier through the inlet windows 11 located on its side walls kah. As a result of this, and due to an increase in the energy of the air in the separation element used in the process of air purification, there is an increase in the efficiency of the cleaning quality, thereby increasing the efficiency of the air purifier itself. The cover 9 has a domed shape and is mounted on the upper base 8, forming a cavity for directing purified air. In the lower part of the side walls, holes 14 are made 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 grilles 15.

The dust hopper 6 contains a disconnecting partition 16 for the formation of compartments 17. The partition 16 between the compartments 17 of the dust hopper 6 is designed to prevent harmful flow of air, and with it dust that may be thrown into the separation element 2. For automatic dust discharge when the engine is stopped each compartment 17 is equipped with a nipple valve 18 mounted on the nozzle 19 of compartment 17. To install the air cleaner on a car or vehicle inside the housing 1 may be provided mounting brackets 20, stiffening the side wall of the air cleaner, and which are located at the same distance from the end walls of the housing, so that the axis of the location of the pair of holes for fasteners is located in the wall of the housing between the inlet windows 11.

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 15, passes into the interior of the air cleaner and is evenly distributed between the separation elements 2 due to the presence of a vertical longitudinal wall 13. When the air stream enters the swirls 4, it receives a rotational screw motion in cyclone tubes 3. Due to the action of centrifugal force, dust particles are thrown to the walls and driven into compartments 17 of the dust collecting hopper 6. Further, the air flow from the central zone, turning chivayas 180 °, arrives in the tube 5 discharging purified air. In this case, when the flow is turned, additional air purification from impurities also occurs. From the tubes 5, the cleaned air enters the interior of the lid 9 and then passes through the outlet pipe 10 to the air filter. When the engine is running due to rarefaction in the hopper 6, the nipple valves 18 are in a closed state, separated particles are collected in them. When the engine stops, the nipple valves 18 open and the separated particles spill out, so the hopper 6 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, and can be mounted on a truck, for example, on the rear wall of the cab. Due to the lateral horizontally located inlet windows of the inventive air purifier, located opposite the open and non-overlapping parts of the air exhaust tubes that are not blocked by cyclone tubes, less resistance is provided and dust extraction efficiency is increased in a wide range of air flow through the air purifier.

The claimed technical solution allows to increase the efficiency of air purification from impurities and reduce the local resistance of the device itself. In addition, this solution, while maintaining a compact design and aesthetics of the design, as well as manufacturability, allows to collectively improve the main indicators of the internal combustion engine and makes it possible to operate the car in dusty environments, thereby increasing the resource and service interval for changing the main filter element of the system car air purification.

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