As request or standard packing |
| Power conversion: It converts the combustion pressure inside the cylinder into mechanical thrust, transferring driving force to the connecting rod and crankshaft. |
| |
| Pressure sealing: Together with piston rings, it seals the combustion chamber to prevent compressed gas and combustion gas from leaking down to the crankcase. |
| |
| Heat transfer: It absorbs high heat from combustion and conducts heat to the cylinder wall via piston rings for cooling. |
| |
| Oil control cooperation: It works with oil rings to scrape excess lubricating oil off the cylinder liner and maintain proper oil film for lubrication. |
| |
| Guiding movement: It keeps linear reciprocating motion stable inside the cylinder liner and prevents side deflection during operation. |
