The primary functions are to provide a wear-resistant surface for piston movement, transfer heat from combustion to the cooling system, maintain cylinder geometry, and ensure proper sealing of combustion gases.
Yes, worn cylinder liners can be replaced through engine rebuilding processes. This is more cost-effective than replacing entire engine blocks and extends engine service life.
Common causes include excessive wear from poor lubrication, overheating leading to thermal cracking, cavitation erosion from coolant pressure fluctuations, and corrosion from combustion byproducts.
