What are the types of oil filters?

[StLandon]

Oil filters are classified into full-flow and bypass types. The oil filter is one of the four filters in a vehicle, 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 engine oil, protecting the engine from wear. Below is an introduction to full-flow and bypass filters: 1. Full-flow oil filter: Most modern automotive engines use full-flow filters, which are typically of the filtration type. Engine oil enters the filter from the outer side of the paper filter element, flows to the center of the filter, and then exits through the outlet into the engine's main oil passage. As the oil passes through the filter element, impurities are trapped on the element. 2. Bypass oil fine filter: Bypass oil fine filters come in two types: filtration and centrifugal. Filtration-type filters face a trade-off between filtration capacity and flow rate, whereas centrifugal-type filters offer advantages such as high filtration efficiency, large flow capacity, and resistance to sediment buildup. Therefore, centrifugal oil filters are commonly used as bypass oil fine filters in automotive engines.
