There are many internal friction parts in the engine, such as the main shaft of the crankshaft and the main bearing, the cam journal and the cam bearing, the piston, the piston ring and the cylinder wall surface, etc. These parts have fast movement speed and bad working environment. They need to have Proper lubrication can reduce wear and extend the life of the engine. As a result, the lubrication system began to play its due role. As a vehicle owner, it is necessary to understand the role of the vehicle lubrication system and maintenance skills.
What is a car lubrication system?
The automotive lubrication system, in a nutshell, is a general term for various components and lubricants (commonly known as "motor oil") that provide lubrication for the engine. The function of the lubrication system is to send the lubricating oil to all parts (crankshaft and bearings, camshafts and bearings, pistons and cylinders) with relative motion in the engine, forming a layer of lubricating film between the friction surfaces, reducing the friction of the parts, Reduce power consumption and parts wear.
As the engine's "blood", engine oil has the functions of lubrication, cooling, cleaning, sealing, and rust-proofing for engine oil. Regular replacement of engine oil has an important protective effect on the engine.
The oil is mainly stored in the oil pan. When the engine is running, it will drive the oil pump and use the pressure of the pump to send the oil pressure to all parts of the engine. The lubricated oil will be returned to the oil pan along the cylinder wall, etc., and used repeatedly.
The enemy of automotive lubrication systems: sludge
What we call “oil sludge†actually refers to the accumulation of solids in car engine oils or in the form of blocky, granular solids that are absorbed inside the engine. The excessive accumulation of sludge in the lubrication system will reduce the heat dissipation effect of the oil, accelerate the wear of the engine, make the oil circulation unfavorable, cause the engine noise to become loud, continue to increase the wear, and eventually cause serious mechanical failure. It can be seen that the sludge is very harmful to the automotive lubrication system and even the engine.
"Reduce Friction": Maintenance Tips for Automotive Lubrication Systems
Since the sludge is so harmful to the car, it is very important for the owner to understand the maintenance techniques to prevent the formation of sludge and the effective method to remove sludge from the lubrication system.
The key to the maintenance of the lubrication system: Changing the oil and oil filter on time The oil in the lubrication system will be repeatedly and fluidly lubricated. It is easy to bring impurities such as metal dust or dust that are worn by the organic parts. If it is not cleaned in time, it is dirty. The oil will accelerate the wear between parts. Therefore, an oil filter is installed on the oil passage of the lubrication system to filter the oil. However, after a long time, the filtered oil will become dirty, and sludge will form in the lubrication system over time. Therefore, after the vehicle has traveled a certain mileage, the owner must change the oil and machine filter for the vehicle.
The use of unsuitable engine oil or inferior engine oil can also form sludge
Each engine equipped with its own specific operating conditions requires the use of a suitable grade and viscosity of oil under conditions of different temperatures and environments. If the owner does not use the oil in accordance with the operating conditions of the engine, then the oil will not only not play the role of lubrication, but will also form sludge, and ultimately damage the engine.
In addition, some car owners are greedy for cheap, buy some low-quality inferior oil from the Internet for the car to change, this is also a kind of injury behavior. These poor engine oils not only do not have sufficient lubrication capacity, but are also particularly prone to sludge formation, damaging the lubrication system and the engine.
