What is the Function of an Engine Oil Filter?
1 Answers
The function of an engine oil filter is to reduce the frictional resistance between moving parts in the engine and minimize wear on components. Engine oil is continuously delivered to the friction surfaces of moving parts to form a lubricating oil film for lubrication. Engine oil inherently contains a certain amount of gum, impurities, water, and additives. During engine operation, the introduction of metal particles, contaminants from the air, and the formation of oil oxidation products increase the impurities in the oil. In addition to filtration, the oil filter also ensures the quality of the engine oil, such as viscosity, acid value, and the content of antioxidants. These indicators deteriorate under prolonged high-temperature operating conditions, so it is necessary to change the engine oil regularly to ensure that these parameters remain within acceptable limits.
