The cylinder liner (code H 21401) is a fundamental part of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 engine, forming a durable and heat-resistant surface within the engine block. Designed to withstand high combustion pressures and reduce friction, it protects the cylinder from wear and extends the engine’s lifespan. Crafted from advanced alloys, this component ensures optimal heat dissipation and smooth piston movement, making it crucial for maintaining efficiency and reliability in industrial and marine engine operations
