What does the oil do to the semi trailer

The role of oil in the semi-trailer. Oil is an indispensable oil in the engine, which plays an important role in the service performance of the engine. Ordinary semi-trailer manufacturers summarize the information about the role of oil in semi-trailers.

The engine is the heart of the car. There are many metal surfaces in the engine that move against each other. These parts move fast and in poor conditions, and the temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear and tear of engine parts and extend the service life. What requirements should qualified lubricating oil meet? So what are the seven functions of lubricating oil?

1. Lubrication:

There is rapid relative sliding between piston and cylinder, between the spindle and the bearing bush, to prevent the parts from wearing too fast, it is necessary to establish an oil film between the two sliding surfaces. An oil film of sufficient thickness separates the surfaces of the parts that slide relative to each other so as to reduce wear.

2, rust prevention and corrosion prevention:

Lubricating oil can absorb on the surface of parts to prevent water, air, acid and harmful gases and parts contact.

3, shock absorption buffer:

When the engine cylinder port pressure rises sharply, suddenly aggravate the piston, piston chips, connecting rod and crankshaft bearing on the load is very big, the load through the bearing transmission lubrication, so that the impact load to withstand the role of buffer.

4. Anti-wear:

Rubbing surface add lubricant, can reduce the coefficient of friction, thereby reducing friction resistance, saving energy consumption, reduce wear: lubricant between the friction surface can reduce abrasive wear, surface fatigue, adhesive wear caused by friction loss.

5, auxiliary cooling:

The oil has a low specific calorific value and does not have a cooling effect in the engine itself. But the engine due to fuel combustion heat, when the engine is working, the oil can bring the heat back to the oil tank and then distribute it to the air to help the water tank cooling the engine, the real cooling effect is the water outside the engine housing (or antifreeze liquid class).

6, clean:

Good oil can bring the carbide, mud and worn metal particles on the engine parts back to the oil tank through circulation, and wash the dirt on the working surface of the parts through the flow of lubricating oil.

7. Sealed and leak-proof:

Oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent outside pollutants from entering.
