Yanmar 6N18 engine block

The Yanmar 6N18 engine block is a strong cast iron structure that forms the main body of the engine, supporting components like the crankshaft and cylinder liners. It uses a duplex (double-wall) design with built-in passages for cooling water, lubricating oil, and air, ensuring efficient performance, durability, and reliability in marine operations. Key Features * Heavy-duty cast iron construction for high strength and long life * Duplex (double-wall) design for rigidity and reduced vibration * Integrated cooling water jackets for effective heat dissipation * Built-in lubrication oil galleries for smooth operation * Boost air passages to support turbocharging * Precision main bearing housing for proper crankshaft alignment * Replaceable cylinder liner arrangement for easy maintenance * Side covers and access doors for inspection and servicing
