What Does Cylinder Wall Mean?

[DiMolly]

Cylinder wall refers to the inner surface of an engine cylinder in an automobile. Here is some relevant information: 1. The cylinder wall is prone to wear due to exposure to high-temperature, high-pressure combustion gases and contact with the high-speed moving piston. To enhance wear resistance and prolong the cylinder's service life, different cylinder structures and surface treatment methods are employed. 2. There are three types of cylinder structures: sleeveless cylinders, dry liners, and wet liners. Generally, lubricating oil is required for lubrication. 3. The stress conditions of a cylinder during operation are influenced by many factors. The pressure difference between the gases inside and outside the cylinder affects it, and the cylinder also bears the reaction force from the steam flow when it impacts stationary parts. Therefore, special attention is needed when selecting a cylinder type. Choosing an unsuitable cylinder may not only damage the equipment but also delay work progress.
