How much do you know about
oil filters
Oil filter, also known as oil grid. It is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine.
oil filters are divided into full-flow and split-flow. The full-flow filter is connected in series between the oil pump and the main oil passage, so it can filter all the lubricating oil entering the main oil passage.The shunt cleaner is connected in parallel with the main oil passage, and only filters part of the lubricating oil sent by the oil pump.
Basic introduction to
oil filter
During the working process of the engine, metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperatures, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, and extend its service life. The
oil filter should have strong filtering ability, small flow resistance and long service life. Generally, several filters with different filtration capacities are installed in the lubrication system - filter, coarse filter and fine filter, which are respectively connected in parallel or in series in the main oil passage. (The one connected in series with the main oil passage is called a full-flow filter, and all the lubricating oil is filtered through the filter when the engine is working; the one connected in parallel is called a split-flow filter). Among them, the coarse filter is connected in series in the main oil passage, which is a full-flow type; the fine filter is connected in parallel in the main oil passage, which is a split-flow type. Modern car engines generally only have a filter and a full-flow oil filter. The coarse filter is used to filter out impurities with a particle size of 0.05 mm or more in the oil, and the fine filter is used to filter out small impurities with a particle size of 0.001 mm or more.
