The Rider Asked, What Will Happen If The Piston Ring Of The Motorcycle Is Broken?

The piston ring is an important part of the internal combustion engine. It mainly plays the role of sealing. If there is no piston ring between the cylinder block and the piston, then they will be slack and weak, and the engine cannot have sufficient negative pressure in the cylinder, so Piston rings are important to the engine

What if the piston ring is broken? It mainly depends on which piston ring is broken, because it is the same piston ring but their division of labor is different, so the faults shown will be slightly different.

The piston ring of a four-stroke engine is divided into an air ring and an oil ring. The air ring is an independent single piston ring, and the oil ring is either combined or integrated.

The main function of the air ring is to ensure that the engine has sufficient negative pressure in the cylinder. Once it damages the negative pressure in the cylinder, it will not meet the design requirements. As a result, the vehicle will have difficulty in starting, the power will drop, and in severe cases, the vehicle will not be able to start directly. .

The main function of the oil ring is to hang the excess lubricating oil on the cylinder wall back to the oil pan to ensure that the lubricating oil does not enter the combustion chamber. Once it is damaged, the most direct manifestation is that the engine burns oil and the exhaust pipe emits blue smoke.

The above are some adverse reactions after the piston ring is damaged, and the damage of the piston ring mainly includes normal wear and human factors.

Needless to say, normal wear and tear, any engine part has a normal service life, and the human factors are nothing more than poor oil quality and unreasonable maintenance. The most important part of unreasonable maintenance is not replacing the engine lubricating oil for a long time.

If the engine lacks lubricating oil, the cylinder piston will be pulled, and the piston ring will be injured. The piston ring in this state will also be broken, which is definitely a sad scene for the engine. , because it will directly scrap the entire cylinder block, so the lubricating oil must be replaced regularly in normal use.
