摘要： Systems and methods are provided for estimating the total base number of used oil in an engine. The systems and methods can involve characterizing the sulfur content and at least one other element content of the oil both before introduction into the engine and after passing through an engine cylinder during combustion. Depending on the aspect, a total base number of the oil prior to use can also be measured, or the total base number before use can be estimated based on the at least one element content.

摘要： A method for improving antiwear performance and demulsibility performance in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and an antiwear additive as a minor component. The antiwear additive includes a zinc dialkyl dithiophosphate compound represented by the formula Zn[SP(S)(OR 1 )(OR 2 )] 2 wherein R 1 and R 2 are independently primary or secondary C 1 to C 8 alkyl groups. The R1 and R2 primary or secondary alkyl groups of the zinc dialkyl dithiophosphate compound, and the amount of the zinc dialkyl dithiophosphate compound in the lubricating oil, are sufficient for the lubricating oil to exhibit improved antiwear performance and demulsibility performance. The lubricating oils of this disclosure are suitable for use in marine system oils for two-stroke marine diesel engines.
