    摘要: The present invention relates to a cylinder lubricant having a BN determined according to standard ASTM D-2896 greater than or equal to 15, preferably greater than 20, preferably greater than 30, advantageously greater than 40 milligrams of potash per gram of lubricant, comprising: one or more lubricating base oils for marine engines, at least one detergent based on alkali or alkaline-earth metals, overbased with metallic carbonate salts, optionally in combination with one or more neutral detergents, one or more fatty amines and/or derivatives of oil-soluble fatty amines having a BN determined according to standard ASTM D-2896 comprised between 150 and 600 milligrams of potash per gram, preferably comprised between 200 and 500 milligrams of potash per gram. This lubricant has sufficient neutralization power vis-à-vis the sulphuric acid formed during the combustion of high-sulphur fuel oils, while limiting the formation of deposits during the use of low-sulphur fuel oils.
