The oil filter is part of the car's grease system. The filter catches and delays the products of wear and cleaning the engine oil.

The motor oil not only lubricates the details, but also flashes the nagar and microscopic shavings that are inevitable in the operation of any mechanism. If you don't clean the oil, the abrasive particles will scratch the surface of the working parts.

History of oil filter creation

It is believed that the car oil filter was invented by Bobby Evans in 1923. He called his "Purolator" product, "collecting" from three other words-"pure oil later"

oil filter device

Filter is part of the engine grease. This shall normally be fitted to the oil pump. To attach the filter, a floor-threaded box is provided with an external thread that coincides with the internal carving at the end of the filter. Inside the body is a filter element, non-return valve and transfer valve. A rubber sealing ring is fitted to the housing of the oil pump around the exit wound in the flat end of the filter.

A special segment or segment key is used to unroll the filter, which can be purchased at the automotive parts store

In some lubrication systems (e.g. Opel Corsa D car), the filter body is stationary and non-replaceable, and the valve is mounted. In these systems, only the soft filter element changes.

How the oil filter works

After starting the engine, the pressure oil starts flowing from the pump to the oil filter through the small inlet orifts located on the circle on the end of the filter.

The leave valve, under pressure, passes the oil to the cavity between the filter body and the filter element. The oil is "infiltrate" through it, filtered and enters the internal cavity of the oil filter. Then, passing through the exit wound, it continues the lubrication system to the fittings.

The vast majority of modern automobiles use a filter element from multiple layers of paper

In case of pollution of the filter element or in cases of high density of the motor oil, the filter opens with the transfer valve. It allows the oil to pass through the filter and then on the whole system without cleaning, bypassing the filter element. The transfer valve is intended to exclude oil starvation of the engine.

When the engine is switched off, the pump will stop feeding the oil to the filter. The non-return valve is being closed, which prevents oil from flow from the top of the lubricating system back to the engine pan. This allows grease to remain in the pits of parts of the GRM mechanism and reduces their wear at the next engine start.

Possible failures of the oil filter

The filter element is able to detect and retain only a certain amount of pollution. When it is filled and "beaten", the filter valve opening is opened, and the system, bypassing the filter element, begins to circulate the raw oil. This accelerates the wear of the engine parts and can lead to serious breakdowns.

The filter return valve holds the oil in the lubricating system. Depending on the size of the filter, its quantity can be quite significant. When the replacement oil is merged from the pallet of the crankcase, account must be taken of the volume that holds the oil filter-it shall be replaced at the same time with the rest of the mass, otherwise the old, used oil will continue to circulate in the lubricating system.  That is why it is very important to change the motor oil and oil filter at the same time.

The magnet attached to the internal surface of the pallet of ACPR is a variety of oil filter. It is used to capture the largest metal abrasive particles

After you have analyzed the status of the filter after the replacement, and the mileage from the time of the previous service, it is possible to judge the state of the car engine as a whole.

The rapid filter contamination can lead to the cooling of the liquid in the oil when it is released from the cooling system.

It is very important to make seasonal changes of oil and oil filter. Winter oil, even compared to all-season oil, more liquid. Therefore, even at a low temperature, it passes through the filter element rather than gets into the engine's lubricating system without cleaning. This could lead to an oil fasting, at least during engine start-up.

The oil filters play an important role in maintaining the engine and extending the service of all parts of the engine. The regular and timely replacement of these filters is no less important than the replacement of the engine oil itself.
