How to Identify the Model of an Oil Filter?
1 Answers
The model of an oil filter can usually be found on the filter housing, which typically includes the manufacturer's part number, or you can refer to the vehicle's maintenance manual. Below is additional information about oil filters: 1. During engine operation, contaminants such as dust, carbon deposits oxidized under high temperatures, sludge deposits, and water continuously mix with the lubricating oil. The function of the oil filter is to remove these mechanical impurities and sludge, ensuring the cleanliness of the lubricating oil and extending its service life. An oil filter should possess characteristics such as strong filtration capability, low flow resistance, and a long service life. 2. An oil filter, also known as an oil strainer, can be categorized into full-flow and bypass types. A full-flow filter is connected in series between the oil pump and the main oil gallery, filtering all the lubricating oil entering the main oil gallery. A bypass filter is connected in parallel with the main oil gallery, filtering only a portion of the oil delivered by the pump. Structurally, oil filters can be classified into replaceable, spin-on, and centrifugal types. The filtration materials used in oil filters include filter paper, felt, metal mesh, and non-woven fabric.
