What is a car engine oil filter?

The car engine oil filter is an important part of the engine lubrication system. Its main function is to filter harmful impurities in the oil from the oil pan to ensure that the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving parts are cleanly and purely lubricated, cooled and cleaned, thereby extending the service life of these parts.

According to the structure, the car oil filter can be divided into replaceable, spin-on and centrifugal types, and according to the arrangement in the system, it can be divided into full-flow and split-flow types. In the car engine, the oil filter is usually located upstream of the oil pump, and its function is to filter out impurities in the oil to ensure that the various parts of the engine are well lubricated and cooled.

The filtering capacity of the oil filter is crucial to the normal operation of the engine. It can filter out metal particles, carbon sediments, soot particles, coal tar, oil oxides, dust and other impurities in the oil, thereby ensuring the normal operation of the engine. If the filtering capacity of the oil filter is insufficient, the impurities in the oil will enter the engine, causing increased wear of engine parts and even failure.

Therefore, it is very important to choose the oil filter that suits your car. Different models and brands of cars require different types of oil filters to ensure the best protection for the engine. It is recommended that car owners replace the oil filter at the same time as changing the oil to ensure the long-term stable operation of the engine.
