2P8889

The 2P8889 Cylinder Liner is a vital engine component engineered to provide a robust and precise bore for the piston within the engine’s combustion chamber. Typically manufactured from high-grade, heat-treated gray cast iron, this liner is designed to withstand the extreme temperatures and pressures generated during the combustion process. Its internal surface features a meticulously honed cross-hatch pattern, which is crucial for optimizing piston ring seating, ensuring proper oil retention and distribution, and minimizing friction and wear, thereby extending the life of both the liner and piston rings. The flange of the liner is often strengthened through processes like roll-burnishing to resist cracking. Manufactured to strict dimensional tolerances, the 2P8889 liner ensures a consistent and stable environment for piston movement, which is essential for maintaining optimal engine compression, controlling oil consumption, and overall engine efficiency.
