How much do you know about filters?
Filter refers to the filter paper from the role of filtering impurities or gas accessories. Generally refers to the car filter, which is an engine accessory.
Filters are divided into different filtering functions: oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter, air conditioning filter, etc. The engine has three types of filters: air, oil, and fuel, which are generally called "three filters", plus air conditioning filters, commonly known as four filters. They are responsible for the filtration of the lubrication system, the medium in the combustion system, the engine intake system, and the cabin air circulation system.
Filter The oil filter is located in the engine lubrication system. Its upstream is the oil pump, and the downstream is the parts that need to be lubricated in the engine. Its function is to filter out harmful impurities in the oil from the oil pan, and supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs with clean oil to play the role of lubrication, cooling and cleaning, thereby Extend the life of these parts.
Filter type
Filter The centrifugal oil filter has a rotor sleeved on a shaft and two nozzles with opposite injection directions. When the oil enters the rotor and comes out of the nozzle, the rotor rotates quickly to make the oil in the rotor body When it is cleaned, the impurities in the oil are centrifugally thrown onto the inner wall of the rotor, and the oil from the nozzle flows back to the oil pan.
Filter The centrifugal oil filter is characterized by stable performance. There is no filter element that needs to be replaced. As long as the rotor is removed regularly, the dirt deposited on the rotor wall can be reused. Its life can be equivalent to the engine. Its shortcomings are complex structure, high price, bulkiness, etc., and higher technical requirements for users.
