What are the two types of oil fine filters?

[VanKaden]

The classification of oil filters: full-flow and bypass. The oil filter is one of the four filters, the other three being the air filter, cabin air filter, and fuel filter. The function of the oil filter is to remove impurities from the oil, protecting the engine from wear. The filtration principles of oil filters can be divided into three categories: mechanical separation, centrifugal separation, and magnetic adsorption. Below is a detailed introduction: 1. Mechanical separation: Commonly seen as mesh filtration, where the filter material has small holes of a certain size on its surface. Solid particles in the oil larger than these holes are trapped on the outer surface of the filter material. 2. Centrifugal separation: Involves passing the oil through a high-speed rotating rotor, where impurities are thrown towards the inner wall of the rotor by centrifugal force, thus separating them from the oil. 3. Magnetic adsorption: Uses permanent magnets to attract iron particles in the oil, preventing them from circulating and damaging engine components.
