[0002] The cylinder liners of large engines are similar to those of ordinary automobile engines. They are parts used to fix the piston and form a sealed space. The difference is that large engines are often larger and more complex, and the cylinder liners cannot be lifted manually. Usually, the cylinder liners are lifted by mechanical equipment and then installed on the engine, which needs to withstand higher pressure and temperature. The cylinder liners of large engines are usually made of high-strength alloy materials to ensure their durability and stability. These materials have good thermal conductivity and wear resistance, and can meet the needs of long-term high-load operation.
