Fuel switch for MAN B&W two stroke engines

As the sulphur cap 2020 is coming closer we advise for MAN B&W two stroke engine types piston rings with special coating. When operating on fuel containing sulphur, the sulphuric acid that is formed during the combustion process will condens on the surface of the liner. That will cause a contolled amount of corrosion and that will create on it's turn a level of wear and that causes a high number of open graphite lamellas in the cast iron matrix. 

When operation on low-sulphur fuel, the level of corrosion is very low and the liner wear is very minimal in most cases. Over time it will lead to polishing of the running surface. As the surface will become so smooth the open graphite lamellas are closed and make it hard to sustain a proper oil film. 

When the oil layer(film) is compromised, the piston rings that are in contat with the liner may generate high friction due to metal-to-metal contact. This will lead to liner scuffing.

Cermet-coated piston rings

Cermet is compositie material composed of ceramic and metal materials. Cermet is ideally designed to have the optimal properties of both ceramic, such as high temperature resistante and hardness, and those of metal. The margin towards scuffin increases. The cermet will recover after an incident. (The cylinder liner may need machining at the next overhaul to ensure correct running-in of the updated rings).
