The three common reasons for engine cylinder pulling!

Engine pull cylinder refers to the cylinder inside the automobile engine is broken or pulled out of the groove mark by the piston.

After the engine pulls the cylinder, the car will have obvious shaking when starting, and the problem of acceleration will be obvious when driving.

Serious cylinder pulling, the engine can not start normally, the car can not work, only overhaul the engine can be solved.

The engine is not lubricated properly

As we all know, in car maintenance, the most basic one is the "three oils" : fuel, oil, transmission oil, of which oil can be said to be the blood of the engine. Because the oil can effectively reduce the friction generated by the engine gear operation, so as to protect the engine.

You should know that with the development of science and technology, the precision of the engine is getting higher and higher, if the long-term maintenance is not done, do not change the oil, the friction generated by the engine operation will become more and more large, and the internal damage is inevitable, which is what we call the cylinder pulling.

Therefore, the car mainly pays attention to regular replacement of oil, it is best to choose high-quality oil.

Engine high temperature

When the car's indicator light appears engine high temperature alarm, the owner must stop driving immediately. Because the engine temperature is too high, the probability of knocking will be increased, and the output power of the engine will decrease in order to reduce knocking. If the temperature is higher, frequent knocking may increase wear and tear, and the vehicle cannot run normally.

After the temperature is high to a certain extent, the oil cannot form an oil film of sufficient thickness, and the wear increases, and even the cylinder is pulled and glued.

As for the causes of high temperature of the engine, the main thermostat failure, coolant problems, oil performance or insufficient oil, cooler blocked, machine filter problems.

Foreign body in the cylinder

When a foreign body enters the cylinder, it will cause friction with the cylinder wall under the movement of the piston, resulting in cylinder pulling problems. As for the culprit of foreign bodies, the first is "carbon accumulation".

Carbon deposit is caused by insufficient combustion of fuel inside the engine, a large amount of carbon deposit will lead to a part of carbon deposit when the piston is running in the cylinder, and the operation of the engine for a long time in such a case will add up to more and more, and finally the friction between the piston and the cylinder will become larger and larger, resulting in cylinder pulling.
