There are many parts that rub against each other inside the engine, such as crankshaft main journal and main bearing, cam journal and cam bearing, piston, piston ring and cylinder wall, etc. These parts move fast and work in harsh environment. Proper lubrication is required between intervals to reduce wear and prolong the life of the engine. As a result, the lubrication system began to play its due role. As a car owner, it is necessary to understand the role of the car’s lubrication system and maintenance skills.
??What is an automotive lubrication system?
Automobile lubrication system, in layman’s terms, is a general term for various components and lubricating oils (commonly known as “oil”) that provide lubrication to the engine. The function of the lubrication system is to deliver the lubricating oil to all parts with relative motion in the engine (crankshaft and bearing, camshaft and bearing, piston and cylinder), and form a lubricating oil film between the friction surfaces to reduce the friction of parts, Reduce power consumption and parts wear.
??Oil is the key to automobile lubrication system
Oil as the “blood” of the engine, has the functions of lubricating, cooling, cleaning, sealing and preventing the engine oil. rust and other effects, regular oil changes have an important protective effect on the engine.
Oil is mainly stored in the oil pan. When the engine is running, the oil pump will be driven, and the pressure of the pump will be used to send the oil pressure to all parts of the engine. The lubricated oil will return to the oil sump along the cylinder wall and other routes, and be recycled for repeated use.
??The enemy of automobile lubrication system: sludge
What we call “sludge” actually refers to deposition in automobile oil, or adsorption Lumpy, granular solids inside an engine. Excessive accumulation of sludge in the lubrication system will reduce the heat dissipation effect of the oil, accelerate the wear of the engine, cause poor oil circulation, cause the engine noise to become louder, continue to aggravate the wear, and eventually cause serious mechanical failures. It can be seen that the sludge is very harmful to the automobile lubrication system and even the engine.
Since the sludge is so harmful to the car, it is necessary for car owners to understand the maintenance skills to prevent the formation of sludge, as well as effective methods to remove sludge from the lubrication system.
