The difference between car air filters and oil filters
2025-07-05
In automotive maintenance, filters play a crucial role. Their primary function is to filter out various impurities that enter the engine, ensuring its proper operation. Among the numerous filters, the air filter and the oil filter are two of the most critical. Although their basic functions are similar, there are significant differences in their functionality, installation location, and specific working principles.
The main function of the air filter is to filter out particulate matter, dust, sand, and other impurities from the air entering the engine. During engine operation, air needs to be mixed with fuel before combustion. If the air contains a large amount of impurities, these impurities will enter the combustion chamber, not only reducing combustion efficiency but also accelerating engine wear. Therefore, the air filter is crucial; it ensures that the air filter and oil filter have significant differences in function, installation location, structure and material, and maintenance and replacement. The air filter mainly filters impurities from the air entering the engine, keeping the air passage unobstructed; while the oil filter mainly removes impurities from the oil, keeping the oil clean. Understanding and properly maintaining these two filters is important for maintaining normal engine operation and extending its service life.
