SEMT Pielstick PC2-5 Cylinder Liner

Product Overview:
The PC2-5 Cylinder Liner is a precision-engineered component designed specifically for PC2-5 series marine and stationary diesel engines, originally manufactured by SEMT Pielstick and now widely supported across the industry. It serves as the critical inner wall of the engine cylinder, providing a durable and thermally stable surface for piston ring sealing, combustion containment, and heat transfer to the engine cooling system.

1. Engine Compatibility: Designed for optimal performance in PC2-5 series medium-speed, four-stroke diesel engines.

2. Material & Manufacturing: Manufactured from high-grade, centrifugally cast grey iron or alloy cast iron. This ensures superior wear resistance, excellent tribological properties, and high thermal conductivity. The internal surface typically features a honed finish or proprietary surface texturing (e.g., plateau honing) to facilitate optimal piston ring run-in and long-term lubrication.

3. Design: Incorporates strategic external fluting or cooling channels to maximize coolant flow and heat dissipation. Precision-machined at the flange and sealing areas to guarantee a perfect fit within the engine block and secure head gasket sealing.

4. Durability: Engineered to withstand extreme internal pressures, high thermal loads, and corrosive combustion by-products, thereby extending engine overhaul intervals.

1. Forms the combustion chamber wall, containing high-pressure gases.

2. Guides the piston assembly throughout its stroke.

3. Transfers heat from combustion to the engine coolant jacket.

4. Provides a controlled, wear-resistant surface for piston ring operation to maintain compression and control oil consumption.
