Cylinder strain is the abrasion of reciprocating position between piston and cylinder liner. The essence of strain is the loss of lubrication between metals and the formation of dry friction. Generally speaking, the scratch problem mainly occurs on some old models. For example, if the carbon deposit is not cleaned for a long time, the volume of the combustion chamber will be reduced, resulting in a relatively large heat load.

Some overhauled engines are not handled properly in the running-in process, which will also cause cylinder pulling. The so-called engine scratch is due to insufficient lubrication of the inner wall of the cylinder and signs of adhesion, so the engine power will drop, and in severe cases, the engine oil will burn. The main reason for this phenomenon is the lack of lubrication, so in general, as long as the engine has enough high-quality lubricating oil, it will not cause cylinder friction, but there are exceptions in everything. If the engine temperature is too high, even if the engine oil is sufficient, the cylinder will be scratched.

This is because when the engine is running at ultra-high temperature, the lubricating performance of lubricating oil will decrease, and the high cylinder liner pressure is caused by carelessness. After filling the oil, forget the next filling time. If it takes more than a few days, it's no big deal Always check the dipstick as long as the engine does not run out of oil. In this case, never be careless. Once the cylinder is damaged, you must disassemble the engine and replace it with a new one. A set of cylinder liners is quite expensive, even if it is new, it is not as good as the original one. Generally speaking, it is difficult for a car to have a cylinder failure. As long as the owner regularly maintains and does not drive violently, this will not happen at all.

This fault can also occur if the oil quality is not good. The jamming machine is not a general fault, but a major fault and needs to be overhauled. In the final analysis, it is the negligence of car maintenance. Although there are many reasons for scratches, the actual probability of scratches is not as high as expected, so in the process of using a car, it is actually less likely to encounter scratches on the cylinder. But we should also pay attention to prediction and avoidance in advance. Another reason why the engine is stuck is to check whether the water in the water tank is insufficient or whether the water pump is running. There are several reasons. If the fan belt doesn't work, it will cause high temperature. If the pump doesn't work well, it will also cause high temperature. Fortunately, there will be a reminder on the dashboard that the water temperature is high or the oil quantity is low.

Therefore, when the thermometer or oil lamp is on, stop and check in time to avoid unnecessary losses. When the carbon accumulated in the cylinder falls into the gap between the piston and the cylinder, the piston will be forced to scrape the cylinder wall when it moves back and forth. If the explosion continues, the oil film will also be destroyed and directly contact with the cylinder wall, resulting in overheating of the cylinder inner wall and scratching of the cylinder. This car keeps high speed for a long time. Excessive speed here means that the speed reaches more than 5000 rpm, which will increase the load of the engine. The water temperature will be too high, which will eventually lead to cylinder friction. Therefore, car owners should develop good habits and maintain their cars in time when using cars at ordinary times.

Especially when you reach the mileage or age, change the oil, and don't drive violently. Often stepping on the accelerator will not only increase fuel consumption, but also damage the engine. As long as we know the causes of congestion, manage it scientifically, use it correctly, strictly abide by the operating rules and take preventive measures, we can reduce or even eliminate congestion.
