What is the relationship between engine cylinder pulling and oil?

As we all know, the power of the engine comes from the piston, which moves at high speed in the cylinder and back, and needs oil to achieve lubrication and cooling.

Now the cylinder wall of many engines is not smooth, but processed into small patterns, the main purpose is to make the oil better adhere to the surface, to ensure the lubrication of the cylinder wall and piston.

When the oil is unable to effectively form a sufficient oil film between the cylinder wall and the piston, or the oil film is destroyed, the cylinder pulling phenomenon may occur.

So, what causes the oil to fail to form enough oil film or oil film damage? Xiaobang will give you an analysis today

Low oil level

When the amount of oil is less to a certain extent, the cylinder wall and piston can not form an oil film, but also can not get the oil cooling, no lubrication protection, will form a pull cylinder.

Oil passage clogging

When the engine produces sludge, it is possible to cause oil channel blockage, and the result is the same as the lack of oil to form a pull cylinder.

Oil pump fault

The oil circulates in the engine, and the power of the lubricating protection of the engine comes from the oil pump. When the oil pump fails, the principle of pulling the cylinder is also the same as the insufficient amount of oil.

Oil viscosity is too low

Engine manufacturers will design different cylinder and piston processing accuracy according to the different design needs of the engine, and will specify the quality specification and viscosity grade of the oil used in each engine. When the viscosity grade of the oil used is too low, the specified viscosity can not be reached; Or the oil is contaminated during use, such as mixing water, fuel or adding inappropriate additives, the use of viscosity is too low, the thickness of the oil film is insufficient, and the cylinder may be formed.

Excessive engine temperature

When the engine temperature is too high, the temperature of the cylinder is too high, and the viscosity of the oil becomes very small because of the high temperature, and it can not stay on the cylinder wall, and it can not form an oil film, and the cylinder pulling phenomenon is likely to occur. Cylinder pulling due to excessive engine temperature is the most common cause. Therefore, usually we must pay attention to the maintenance and inspection of the engine cooling system, such as regularly replacing the coolant, checking the condition of the water tank and the amount of coolant.

Piston carbon deposit

When the piston produces carbon deposit, the hardness of carbon deposit is larger, the oil film is destroyed with the high-speed movement of the piston, and the cylinder is worn to a certain extent when the engine is operated for a long time.

In short, the correct selection of oil, timely replacement and maintenance, good car habits, the fault will be far from your car, free from your troubles.
