An oil filter, also known as an oil strainer, is a cylindrical component designed to remove impurities such as dust, metal particles, carbon deposits, and soot from engine oil, thereby protecting the engine. Key details about oil filters are as follows: 1. Function of an oil filter. It filters out harmful contaminants from the oil in the oil pan, delivering clean oil to moving parts like the crankshaft, connecting rods, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning effects, thus extending the lifespan of these components. 2. Structure of an oil filter. Types include replaceable, spin-on, and centrifugal filters; based on system layout, they can be categorized as full-flow or bypass filters. The filtration materials used in oil filters include filter paper, felt, metal mesh, and non-woven fabric.
