Marine Cylinder Head Manufacturer's Main Products

Wärtsilä cylinder head 6L20

Wärtsilä cylinder head 6L20 is constructed using durable grey cast iron. It incorporates several advanced features to optimize performance and reliability:

  • Efficient Cooling: The thermally loaded flame plate is effectively cooled by circulating cooling water. This water is directed from the periphery to the center of the head, ensuring efficient heat dissipation.

  • Valve Rotators: Each valve is equipped with valve rotators, which enhance valve movement and minimize wear, contributing to extended valve lifespan.

Sulzer Cylinder Head RTA84T

Sulzer RTA84T low-speed marine diesel engines are specifically designed to provide efficient propulsion for extremely large crude oil tankers (VLCCs and ULCCs). There are several features of Sulzer cylinder head RTA48T:

  • Secure Fastening: The cylinder cover is secured by eight elastic studs, providing a reliable and secure attachment to the engine block.

  • Anti-Corrosion Cladding: To protect the cylinder covers from hot corrosive or erosive attack, anti-corrosion cladding is applied downstream of the injection nozzles. This safeguards the cylinder covers and helps maintain their integrity over time.
