What is the function of the engine lubrication system?

Engine lubrication system function: it can make the oil film contact between the moving parts, the cooling effect uses the fluidity of the oil, the cleaning effect circulates the flowing oil, the sealing effect uses the viscosity of the oil, the anti-rust effect, in addition, there is also the vibration absorption effect. The oil absorbs vibrations between the moving pairs, which reduces noise and extends the life of the engine.

The function of the lubrication system is to continuously supply the oil to the friction surface of each moving part to form a thin layer of lubricating oil film to avoid the adverse consequences of wear and heating caused by direct friction between the parts, and increase the movement resistance. The lubrication system has the following five functions.

1. Lubricating engine oil can make the oil film contact between moving parts, reduce friction resistance and power loss, and reduce the wear of machine parts.

2. The cooling effect uses the fluidity of the engine oil to take away part of the heat of the engine parts and prevent the parts from being burned due to excessive temperature.

3. The cleaning effect is to circulate the engine oil, and take away the metal particles that the engine grinds during the work, the dust that sucks people from the atmosphere and some solid substances produced by fuel combustion, so as to prevent the formation of abrasives between the parts and aggravate the wear.

4. The sealing effect uses the viscosity of the engine oil to make the oil adhere to the surface of the moving parts, improve the sealing effect of the parts, and reduce air leakage.

5. Anti-rust effect: the lubricating oil film is adsorbed on the metal surface, separating air and water, and playing the role of anti-rust and anti-corrosion.

Lubricate the engine friction pair, and also have the functions of cooling, hydraulic, sealing, and shock absorption.

The functions of the engine lubrication system are: 1. Lubrication: when the engine is running, a certain oil film is kept in the middle of the relatively moving parts and stored between the surfaces, so that the friction between the parts is not directly generated, so that the friction coefficient is reduced, the friction loss is reduced and the surface wear of the moving parts is reduced; 2. Cooling effect:

When the engine is working, a large amount of heat is generated, and the heat energy is converted into kinetic energy. In addition, the lubrication system also has a cleaning effect, when the engine is working, the lubricating oil can take away the dirt and fine particles generated by the friction on the parts, so as to keep the parts clean and reduce the friction.

The functions of the engine lubrication system are: 1. Lubricate the surface of moving parts, reduce wear and power consumption of the engine; 2. Clean the friction surface, clean the grinding debris and foreign matter; 3. The amount of heat generated by cooling friction; 4. Improve the tightness between moving parts to prevent air leakage or oil leakage; 5. Protect the surface of parts to prevent corrosion and rust; 6. As hydraulic oil; 7. Form an oil film on the surface of moving parts to absorb impact and reduce vibration. The engine lubrication system consists of an oil supply device, a filter device and an instrument signal device, and its working principle is:

The main oil pump sucks the lubricating oil from the oil pan, pumps the lubricating oil into the oil cooler, and the cooled lubricating oil enters the main oil pipe at the lower part of the body after filtering through the oil filter, and is transported to each lubrication point under pressure.

The role of the engine lubrication system: oil film contact can be formed between the moving parts. The cooling function utilizes the fluidity of the oil, the cleaning function utilizes circulating oil, and the sealing function utilizes the viscosity and anti-rust function of the oil.

In addition, it has a vibration-absorbing function. The oil absorbs vibrations between the acting pairs, which reduces noise and extends the life of the engine.

The function of the lubrication system is to continuously supply oil to the friction surface of the moving parts to form a thin layer of lubricating oil film, so as to avoid adverse consequences such as wear and heating caused by direct friction between the parts, and increase the movement resistance. The lubrication system has the following five functions.

1.Lubricating oil can create oil film contact between moving parts, reduce friction resistance and power loss, and reduce component wear.

2.Cooling uses the fluidity of the oil to take away some of the heat from the engine parts, preventing the parts from burning out due to excessive temperature.

3.Circulating engine oil is used for cleaning, taking away the metal particles that are worn off when the engine is working, the attractive dust in the atmosphere, and some solid substances produced by fuel combustion, preventing the formation of abrasives between parts and aggravating wear.

4.The sealing function uses the viscosity of the oil to make the oil dust surface touch the surface of the transport and information carrying parts, improve the sealing effect of the parts, and reduce air leakage.

5.Anti-rust function: The lubricating oil film is adsorbed on the metal surface to separate the air body from the water, thereby preventing rust and corrosion.

The functions of the engine lubrication system are specifically introduced: 1. Lubrication effect: The oil can make the oil film contact between the moving parts, reduce the friction resistance and power loss, and reduce the wear of the parts. 2. The cooling effect uses the fluidity of the engine oil to take away part of the heat of the engine parts and prevent the parts from being burned due to excessive temperature.

3. The cleaning effect is to circulate the engine oil, and take away the metal particles that the engine grinds during the work, the dust that sucks people from the atmosphere and some solid substances produced by fuel combustion, so as to prevent the formation of abrasives between the parts and aggravate the wear. 4. The sealing effect uses the viscosity of the engine oil to make the oil adhere to the surface of the moving parts, improve the sealing effect of the parts, and reduce air leakage. 5. The principle of anti-rust is that the lubricating oil film is adsorbed on the metal surface to separate the air and water to prevent rust and corrosion.

1) Lubrication.

When the engine is running, a certain oil film is kept in the middle of the relative moving parts and stored between the surfaces, so that the friction between the parts is not directly connected to the ballast, so that the friction coefficient is reduced, the friction loss is reduced and the surface wear of the moving parts is reduced, the effective power of the engine is improved, and the service life of the parts is ensured.

2. Cooling effect:

When the engine is working, a large amount of heat is generated, and the heat energy is converted into kinetic energy, and the work is done. The excess heat after the work must be quietly dissipated in time. Otherwise, the temperature will be too high and the mechanism will be damaged.

The lubricating oil takes away the heat in some parts to keep the temperature of the working part from being too high.

3) Cleaning effect.

When the engine is working, the lubricating oil can carry away the dirt and fine particles generated by friction on the parts, so as to keep the parts clean and reduce wear.

4) Occlusive effect.

The lubricating oil closes the gap between the piston and the cylinder. The oil film formed by the lubricating oil can increase the tightness to prevent gas crossing, and make up for small gaps to prevent noise from imitating.

The engine lubrication system refers to the functions of lubrication, cleaning, cooling, sealing and anti-corrosion.

1. Lubrication: lubricate the surface of moving parts, reduce friction resistance and wear, and reduce the power consumption of the engine.

2. Cleaning function: The engine oil is continuously circulated in the runwei pants slip system to clean the friction surface and take away abrasive debris and other foreign substances.

3. Cooling effect: the continuous circulation of engine oil in the lubrication system can also take away the heat generated by friction and play a cooling role.

4. Sealing effect: form an oil film between the moving parts to improve their tightness, which is conducive to preventing air leakage or oil leakage.

5. Anti-rust and corrosion rubber: form an oil film on the surface of the parts, protect the surface of the parts, and prevent corrosion and rust.
