In fact, the role of engine oil is more than that. It has many kinds and complex components. We will talk about it later.
The oil pump is the most important part in the lubrication system. Its function is to ensure that the oil circulates in the lubrication system and can deliver a sufficient amount of oil at a high enough pressure to the lubrication parts at any engine speed.
The structure of oil pump can be divided into gear type and rotor type.
The advantages of gear oil pump are high efficiency, small power loss and reliable operation; The disadvantage is that the intermediate transmission mechanism is required, and the manufacturing cost is relatively high.
The advantages of rotor type oil pump are compact structure, large oil supply, uniform oil supply, low noise and high oil suction vacuum. Rotor pumps are widely used in modern engines.
In the lubrication system, there are also some valve components, which are mainly used to limit or protect the system pressure, protect the lubrication system components, and prevent the return of lubricating oil.
Pressure limiting valve: installed on the oil pump end cover. It is used to limit the maximum oil pressure in the lubricating system
Bypass valve of primary filter: installed on the primary filter. If the filter element of the primary filter is blocked by impurities, the engine oil will open the bypass valve and directly enter the main oil passage to ensure that there is enough lubricating oil for all parts of the engine.
Full flow oil filter Most of the full flow oil filters used in modern automobile engines are filter type. The oil enters the filter center from the periphery of the paper filter element, and then flows into the main oil passage of the engine body through the oil outlet. When the oil flows through the filter element, impurities are trapped on the filter element. The paper filter element is made of microporous filter paper treated with phenolic resin, which has high strength, good corrosion resistance and moisture resistance. Paper filter element is widely used because of its light weight, small volume, simple structure, good filtering effect, low resistance and low cost.
