Abstract
The cylinders of a two-stroke cross-head marine diesel engine characterised by a power output of 4,000 kW per cylinder or greater are lubricated by a cylinder lubricant comprising a basestock of lubricating viscosity, on overbased metal detergent and an oil-soluble sulfur-containing compound or phosphorus-containing compound, thereby to raise the onset temperature of scuffing-type mechanical wear of the cylinder walls.
