Some Methods to Prevent the Wear of Piston-Cylinder When Using Low Sulphur Fuel Oil (LSFO) for All Ships Sailing on Emission Control Areas (ECAs)

Abstract

The IMO (International Maritime Organization) of MARPOL 73/78, Regulations for the Prevention of Air Pollution from Ships, has been adopted and took effect from May 2005 and had significantly to the present. The increases in a number of ships are leading to a large of number of exhaust gas emission into the environment. It is main reason that the Annex VI, MARPOL 73/78 is extremely necessary to require the ships need to comply. Furthermore, the marine fuel is used mainly for marine diesel engine nowadays, heavy fuel oil with high sulphur content. However, the IMO's regulations show that from January 1, 2020, fuel oil that is used on board should have no more than 0.50% sulphur content in order to protect the environment. Its benefit will have positive effect to the environment. On another side, the diesel engine operation especially the corrosion phenomenon for all piston-cylinder components will have negative effect due to the use of low sulphur fuel oil (LSFO). This chapter concentrates on researching the above phenomenon and gives some methods to restrict the negative influence on using the kind of low sulphur fuel oil. The results are fundamental knowledge for all vessels to comply the regulations of MARPOL 73/78 while sailing on ECAs.
