Automotive filters: types and their purpose

Air filters clean the air entering the engine from harmful contaminants, ensuring optimal working conditions and reducing abrasion by friction engine components interacting

In the process, the internal combustion engine (ICE) consume large amounts of air. Established that (on average) for the combustion of 1 liter of fuel required as many as 10 000 cubic decimeters air, which, depending on the climate and season contains various types of pollution, such as dust, pollen, insects, etc. They can cause damage to the engine, thereby significantly reducing its service life. That is why the filters kotoryemogut hold up to 99.9% of impurities in the air and falling into the engine air intake system built into the car.

Air filters consist of a hood, located near the engine, and a replaceable filter tips (cartridge).

By design, the air filters are divided into light, used in passenger cars, pickup trucks and SUVs, and heavy, mounted on trucks. Light filters have a rectangle or circle. Round filters are used in the older cars, and have a relatively small amount of filter material compared to the body. In this sense, the rectangular filter is much better. Therefore, they are used in new models of cars. Another advantage of the panel filters - their ecological value. Most of these filters do not contain metal parts, which facilitates the processing of used filters.


Oil filters effectively remove from the engine or transmission oil harmful pollution resulting from abrasion and degradation of engine oil into each internal combustion engine (ICE), a oil filter. Their function is to prevent the entry of any external contamination in engine lubrication system, and at the same time to remove any contamination that was created during engine operation. The main sources of pollution: particulate matter trapped in the combustion chamber with the air and fuel, wear products moving engine parts, water and carbon residues formed during the combustion process, the results of the collapse of the engine oil.

Modern engine oil filters are different designs. They can be divided into two groups, according to a method of preventing contamination. Barrier filters, which is used as a cleaning layer porous material absorbs pollution when oil flows through it. Energy filter, which is separated from the oil pollution in the vortex field of gravitational and magnetic forces. Engine lubrication system equipped with one or the other type of filters, or both simultaneously. The use of a suitable type of filter in the lubrication system of the car is its type and is determined during the development of the engine.

Placing two filters in the lubrication increases cleaning efficiency and extending the duration of the filters. Fuel filters provide a complete cleaning of the fuel particles of particulate matter, especially dangerous for elements of the fuel system and engine. Fuel supply advanced engine includes many fine elements, whose correct operation is required for the smooth operation of the engine. Fuel pump, carburetor or injectors are very sensitive to any impurities in the fuel. Determined that each liter of fuel may contain up to a milligram of various impurities. Special filters are installed in the fuel system of the vehicle to provide the best operating conditions of the engine, and extend the life of its parts. The purpose of these filters is to remove solid components, water, paraffin embedding of the fuel, and precipitation of organic matter (bacteria in the water that enters the fuel). Real efficiency fuel filter depends on the quality of fuel used, as well as the structural features of the engine. In the carburetor fuel systems of gasoline engines with filters 99% efficiency retain particles up to 8 mm in diameter, and fuel injection systems, filters achieve the same efficiency only with particles of diameter 3.2 mm. Obtaining such a high degree of purification and, at the same time, maintaining a long filter life, made possible by the use of multi-stage purification. All filters used in the fuel systems - flow, and therefore all of the fuel that enters the combustion chamber must pass through them. Moving from the fuel tank to the combustion chamber, the fuel is at least through one filter, but sometimes even three.

Hydraulic filters are adapted to operate in extreme conditions due to high pressure and dynamic changes in oil consumption. During the entire period of operation keep the high efficiency removal of contaminants from the oil.

Hydraulic filters are used in various devices and mechanisms, often working under difficult conditions. The reliability of the hydraulic system depends, in large part, on the properties of oil and reliability of each element (pump, servo, filling, valves, etc.) are subject to high pressure, friction and other mechanical influences. To ensure the best operating conditions of hydraulic special filters to clean the hydraulic oil.
