CYLINDER OIL , SULFUR CONTENT IN FUEL AND COLD CORROSION
Now a days the average sulfur content of HFO used for marine diesel engines is about 2.7%. This will further reduce with forthcoming stricter emission legislation. With such varying content of sulfur in fuel forces us to use appropriate cylinder lub oil in the engines. With the enforcement of new legislation regarding SOx emission, the engine maker's declared without giving any thought that their engines are compatible with fuel having low sulfur including distillate fuel. But there was deep research and study about the use of appropriate cylinder oil in relation to varying sulfur content of fuel.This study was required because of the presence of cold corrosion in cylinder liners. The cold corrosion is considered to be the most influencing cause of wear in the liners, which is basically due to the condensation of SO3 in exhaust gases. In order to neutralize sulfuric acid the cylinder lub oil must contain appropriate alkaline components. The B...
