Detailed introduction of the importance of the oil filter to the car

The importance of oil filter to the car

Even drivers who do not know mechanical knowledge know to change the oil and oil filter regularly. However, other liquids and filters also require regular maintenance. Clean oil and air also ensure the health of the occupants. Therefore, every time we have small maintenance and large maintenance, we have the replacement of organic oil and oil filter.

Oil filter function: filter impurities

Under normal circumstances, the various components in the engine are normalized by the lubrication of the oil, but the metal debris generated during the operation of the components, the incoming dust, the carbon deposits oxidized at high temperatures, and some of the water vapor will continue to mix. In the oil, a long time will reduce the normal service life of the oil, and in severe cases, it may affect the normal operation of the engine.

Therefore, the role of the oil filter at this time is reflected. Simply put, the role of the oil filter is mainly to filter most of the impurities in the oil, to keep the standby oil clean and prolong its normal service life. In addition, the oil filter should also have the characteristics of strong filtration capacity, low flow resistance and long service life.

Oil filter composition: housing + filter

Simply put, the oil filter is mainly composed of two parts: the filter element and the housing.
Of course, there are auxiliary components such as sealing ring, support spring, and bypass valve. The functions of these auxiliary components are not small. For example, the function of the bypass valve is that the oil will pass through when the filter paper fails due to excessive impurities. The valve flows into the engine for lubrication.

However, only the appearance of what we see is only the whole of the oil filter, and the filter paper, bypass valve and other parts are not visible.
Oil supply priority is an important principle to follow in design: that is, in extreme cases, even if the filter is clogged, it is necessary to ensure that the engine has sufficient oil supply to prevent the risk of dry grinding; especially in cold This is especially important when starting up.
Our filter is mainly through the bypass valve and check valve to fully guarantee the realization of the above functions. However, often the inferior oil filter or the bypass valve is normally open (the opening pressure is very small), so that the dirty oil is not filtered to the engine lubrication part under normal conditions, or can not be opened, so that the cold start or oil filter The engine is dry-ground when blocked.
Oil filter maintenance cycle: a consumable part
Normally, the oil filter is classified into the consumables, and in terms of replacement, the oil and oil filters are basically replaced together. If it is not replaced for a long time, it may cause the oil filter to lose its function and eventually affect the engine operation.
Proper installation and regular oil filter can prevent impurities from mixing into the engine during use of the internal combustion engine, preventing wear and movement of moving parts and oil blockage. When changing the lubricating oil, the oil filter must be replaced at the same time, which can better ensure the efficiency of the lubricating oil and will not affect the quality of the lubricating oil.
It is important to purchase a genuine oil filter, because the inferior oil filter will cause great damage to the vehicle, which will cause the car to wear, block the oil passage, and cause oil pressure disorder.
