What is the function and lubrication method of automobile lubrication system?

1. The effect of the lubrication system: lubricate the surface of moving parts, reduce friction resistance and wear, and reduce the power consumption of the engine.Cleaning function: The oil continues to circulate in the lubrication system, cleans the friction surface, and takes away abrasives and other foreign matter.

2. The all-round maintenance of the lubrication system is conducive to improving the service quality of repair shops and special maintenance stations, increasing business projects, and continuously stabilizing and expanding the vehicle source.

3. The basic task of the lubrication system is to continuously supply lubricating oil to the friction surface of each part to reduce the friction and wear of the parts. Although the lubrication system does not participate in the engine function conversion, it can ensure the normal operation of the engine and make it have a long service life.

4. The role of the lubrication system The lubrication system, as the name implies, plays the role of lubricating internal parts. When the engine is working, a sufficient amount of clean oil with appropriate temperature will be continuously transported to the friction surface of all transmission parts, thus forming a layer of lubricating oil film.

5. The lubrication system is a component of the engine, and its functions are: lubrication, cooling, cleaning, sealing and buffering.

Engine lubrication system

1. Main oil channel - is a key component of the lubrication system, immediately sending Cast on the motive cylinder block and cylinder head, which is used forTransport lubricating oil to each lubrication position Pressure relief valve - used to limit the working pressure of the lubricating oil pump. Prevent the actual effect of lubrication from being reduced due to too much residual oil entering the fine filter.

2. Function of the engine lubrication system: When the lubrication function engine is running, the oil film can be formed between the relative moving parts, reducing the friction coefficient, reducing friction loss and surface wear, and improving the effective power of the engine, so as to ensure the service life of the parts.

3. The main components of the engine lubrication system are as follows: oil pump: the function is to increase the oil pressure and ensure the continuous circulation of oil in the lubrication system. At present, there are two widely used oil pumps: external megging oil pumps and internal megging oil pumps. Among them, gear oil pump and rotary oil pump are two commonly used oil pump types.

4. The function of the gasoline engine lubrication system is to form an oil film between the various moving parts of the engine to reduce friction and wear, and ensure the normal operation of the engine.

5. Splash lubrication: When the engine is working, the oil droplets splashed up when the crankshaft, camshaft and other moving parts rotate or from the oil hole on the connecting rod head are used to lubricate the friction surface. The objects of lubrication are cylinder walls, cams, piston pins, etc.

What is the function of the engine lubrication system?

What is the function of the engine lubrication system? Refer to the correct answer: form an oil film on the surface of moving parts to reduce wear and power loss, and play a lubricating role. The circulating lubricating oil flows on the surface of the parts.Move, absorb part of the heat generated by the friction of the parts, maintain the appropriate working temperature of the parts, and play a cooling role.

The basic task of the lubrication system is to continuously supply lubricating oil to the friction surface of each part and reduce the friction and wear of the parts. Although the lubrication system does not participate in the engine function conversion, it can ensure the normal operation of the engine and make it have a long service life.

The function of the lubrication system is to transport a certain amount of clean lubricating oil to the surface of the relatively moving parts to achieve liquid friction, reduce frictional resistance, and reduce the wear of the machine parts. And clean and cool the surface of the parts. The lubrication system is usually composed of a lubricating oil channel, an oil pump, an oil filter and some valves. Cooling system.

The functions of the engine lubrication system are as follows: reduce friction resistance: lubricationThe action of the engine oil can form an oil film contact between the moving parts to reduce friction resistance and power loss and reduce the wear of the machine parts. Prevent the temperature of parts from being too high: The cooling effect is to use the fluidity of the oil to take away part of the heat of the engine parts to prevent the parts from being burned due to excessive temperature.

The main function of the lubrication system is to continuously supply lubricating oil to various sports parts to reduce the wear of moving parts and engine power loss.
