Composition And Function of Engine Lubrication System

The lubrication system is the basic protection for the normal operation of the internal structure of the car, and it can be said to be an essential part of the car. If there is an abnormality in the lubrication system, it will not only increase the wear of the engine parts but also cause a cylinder explosion. Therefore, we must have a very good understanding of the existence of this system. So what is the composition and function of the engine lubrication system? Let's find out together.

Components and functions of engine lubrication system

Oil pan - as the name suggests is used to store lubricating oil. Secondly, the oil pan can also dissipate heat for the lubricating oil.

Oil pump——A certain amount of lubricating oil is pumped out from the oil pan, pressurized by the pump for oil, and sent to the surface of each engine part (circulation), so as to play a role in lubrication.

Oil filter - to filter out impurities, wear debris, sludge and moisture in the lubricating oil to ensure that the lubricating oil in the engine parts is relatively clean. Such as kubota d902 oil filter.

Oil machine filter - mainly to filter out the impurities with large particle sizes in the lubricating oil to ensure the quality of the oil quantity.

Main oil passage - is an important part of the lubrication system, cast directly on the cylinder block and cylinder head used to deliver lubricating oil to each lubricating part

Pressure limiting valve - used to limit the lubricating oil pressure output by the oil pump. Avoid the decrease of lubricating effect due to too much oil entering the fine filter.

Oil pump suction pipe - to prevent large particles of impurities in the oil from entering the lubrication system.

Crankcase ventilation device——to prevent part of the combustible mixture and exhaust gas from escaping into the crankcase through the gap between the piston ring and the cylinder wall.

The role of the engine lubrication system

The lubrication system, as the name implies, is to lubricate the internal parts. When the engine is working, it will continuously deliver a sufficient amount of clean engine oil at an appropriate temperature to the friction surfaces of all transmission parts, thereby forming a lubricating oil film. Not only can it effectively alleviate the friction of parts, but it can also reduce power loss, ensure the service life of the engine, and provide a good working condition.
