The oil filter, also known as the machine filter, is located in the engine lubrication system. The upstream of the auto oil filter is the oil pump, and the downstream is the parts that need to be lubricated in the engine. The auto oil filter filters out harmful impurities in the oil from the oil pan, and supplies the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs with clean oil for lubrication, cooling, and cleaning. Thereby extending these parts.
Engine oil has the function of lubricating and cleaning corrosion and rust in the car. In the cleaning process, there will inevitably be a lot of dust, particulate metal and carbon deposits caused by insufficient combustion. These can be removed by the operation of the engine oil. All the dirt is taken away, but the dirt that is taken away needs to be filtered by the car oil filter. The filtered oil will become cleaner and cleaner, and it has a non-negligible role in protecting the engine. Only the oil filter can ensure that the dust, metal debris, various carbon deposits and impurities carried by the engine during the working process can be effectively filtered, extending the life of the engine and reusing the oil in the entire lubrication system.
According to the structure, the auto oil filter can be divided into replaceable, spin-on, and centrifugal; according to the arrangement in the system, it can be divided into full flow and split flow. Filter materials used in auto oil filters include filter paper, felt, metal mesh, and non-woven fabrics.
The replaceable auto oil filter is to put the filter element and other parts, such as springs, sealing rings, etc., into a metal shell, and connect the shell filter element and the like with a metal filter seat through a pull rod. The advantage of the replaceable auto oil filter is that it is low in cost and only needs regular maintenance and replacement of the filter element; the disadvantage is that there are too many sealing points, and the maintenance and replacement of the filter element may miss parts, which is easy to cause loopholes, and replacement is troublesome.
The characteristic of the spin-on filter is that there is a check valve, a bypass valve, and only one sealing point inside. The integral replacement greatly improves the sealing performance and is easy to replace. The filter element material is mostly imported filter paper, so the filtration efficiency is high. , The flow resistance is small, and the life is long.
Auto oil filter is an important part of engine lubrication system. The function of the oil filter is to filter out the impurities produced during the operation of the engine and the deposits produced during the use of the oil. Reduce the wear of parts in the lubrication system and avoid blockage of the oil circuit. Blockage of the oil circuit will affect the normal use of the engine.
