When operating cars in hot climates, atmospheric dust, i.e. quartz particles, through the engine breathing system are mixed with fuel in the engine along with the air flow, as a result of friction during the reciprocating movement of the piston, metal particles appear as a result of monitoring the processes mechanical corrosion and decay. Taking into account the fact that abrasive corrosion products have a very negative effect on engine efficiency, it is supposed to capture metal particles formed during corrosion by installing a magnet on the engine lubrication system dipstick.

The development of the automobile industry in our country is growing rapidly. Today, based on the localization program, many parts of automobile parts are produced in our Republic. In particular, "General Motors Powertrain-Uzbekistan" JSC, located in the Tashkent region, launched the production of car engines. 960 projects were implemented in Uzbekistan within the 2017 localization program. In the next two years, it is planned to implement about 1150 projects worth 3.4 billion dollars in Uzbekistan. This was announced at the press conference dedicated to the prospects for the development of industrial cooperation and localization processes at the Ministry of Economy of the Republic of Uzbekistan. In particular, in 2022, at the expense of the implementation of 960 projects, the production of localized products worth 6.5 trillion soums is set. In addition, 122 types of products that need to be localized based on domestic standardization have been identified. The process of studying additional reserves (reserves) for reducing the import of products showed that there is an opportunity to reduce imports by an additional 23% due to the expansion of inter-sectoral industrial cooperation and the organization of production of modern types of products that replace imports. The main reason for the increase of dust particles in the atmosphere is the change in the natural and climatic conditions. As a result of an increase in the air temperature from the normal level, due to a decrease in the relative humidity of the air in the atmosphere, dust particles on the ground rise into the atmosphere as a result of the wind. During the operation of vehicles, dust particles in the atmosphere together with the air flow through the respiratory system of the car, that is, 95-99% of the dust particles are retained by the air filter, and the remaining 1-5% are mixed with fuel. is introduced into the combustion chamber. As a result, during the reciprocating reciprocating movement of the piston, the friction of dust, i.e., quartz particles, between the piston and the cylinder mirror causes corrosion and metal particles are separated. Separated abrasive wear products, mixed with lubricants and falling into the crankcase, are collected at the bottom of the pallet. As a result, in the process of moving together with the oil, the friction working at high load lubricates the surface of the contact surfaces and takes away the excess heat with it. In this process, abrasive wear products cause rapid wear on contact surfaces that touch each other, such as cylinder-piston group, crankshaft and connecting rod necks. As a result of this, a gap appears between the sleeve and the piston, and during the compression stroke of the fuel-air mixture in the combustion chamber, the gases pass into the crankcase due to high pressure, and the oil enters the combustion chamber and burns together with the fuel. As a result, the power of the engine decreases, the consumption of fuel and lubricants increases, and indicators of durability and reliability decrease. In order to prevent this, by installing a magnet on the dipstick for measuring the level of oil in the crankcase, it is necessary to catch abrasive wear products in the oil. Trapped metal particles and crankcase oil are cleaned in the process of measurement. As a result, economic savings are achieved.
