Engine Cylinder Liner and piston ring is a critical friction pair of a car which works in high temperature and pressure. The friction pair is easily abraded and out of shape because of working in a complex environment for a long time, which shortens the life of the Engine and results in a waste of money. That's the reason why it means so much for the piston ring manufacturer and the cylinder liner manufacturer to find a way to mitigate the situation.
There are several reasons for the abrasion such as the high temperature and the lack of lubrication. It's normal for an engine to be abraded for structural reasons. While, an inappropriate use and maintenance will probably result in an uneven wear.
A combustible mixture of air and fuel burning in the engine can produce water and acidic oxide, which will finally be turned into mineral acids. The mineral acids coupled with other organic acids produced while burning will corrode the surface of the cylinder liner and the engine main bearing. The corrosion will be scraped by the piston ring during the friction, which causes the deformation of the cylinder liner.
Mechanical impurities such as the dust in the air or the gases in the lubricating oil will slip in and out of the cylinder with the master cylinder piston, which increases the abrasion.
Things will get worse if the effect of the lubricating oil filter is poor. Metal fragment will pile up in the bottom of the engine, which will definitely cause great damage to the engine cylinder liner and the piston ring.
In view of the above reasons, following measures should be taken to maintain the engine cylinder liner and the piston ring:
1. Remember, a car should be started with a low gear until the temperature of the oil is normal. In this way you can reduce the wear caused by the shortage of lubricating oil in gear oil pump.
2. Choose the best value of the lubricating oil according to the seasons and the performance of the engine. Keep this in mind that we should never purchase inferior crude oil.
3. Keep the temperature of the engine between eighty to ninety degrees. Water vapor condenses into water droplets in the engine to produce acids because of the low temperature just as mentioned earlier. Meanwhile, accidents occur easily when the temperature of the engine is over ninety degrees.
