The cylinder liner (code KS 21401) is a critical component in the Sulzer ZA40S engine, providing a durable and heat-resistant surface for the piston’s movement. Designed to withstand high temperatures and intense pressure, the liner ensures efficient combustion and minimizes wear on the engine block. Manufactured from high-quality materials, it offers excellent resistance to corrosion and thermal expansion, enhancing engine longevity and performance. Regular inspections and timely replacements of the cylinder liner are essential to maintaining optimal engine efficiency and preventing premature wear in demanding marine and industrial applications.
