Lubricants containing a bimetallic detergent system and a method of reducing NOx emissions employing same |
| abstract |
A lubricating oil composition comprising a major amount of an oil of lubricating viscosity and an additive system comprising (A) from about 0.1 to about 5% by weight of a detergent composition comprising at least two metal overbased compositions wherein said detergent composition consists essentially of (A-1) at least one alkali metal overbased detergent and (A-2) at least one calcium overbased detergent, wherein the ratio of total base number on a per 100 TBN and diluent-free basis contributed by the alkali metal detergent to the total base number contributed by the calcium detergent ranges from about 99.5-20 to about 0.5-80; (B) from about 1 to about 10% by weight of a succinimide dispersant; and (C) from about 0.1 to about 5 % by weight of a metal dihydrocarbyl dithiophosphate of the formula (I) wherein R<1 >and R<2 >are each, independently, hydrocarbyl groups containing from 3 to 13 carbon atoms, M is a metal and n is an integer equal to the valence of M. Also disclosed are methods for cleaning the combustion chamber of internal combustion engines, a method for reducing fuel consumption of internal combustion engines and a method for reducing NOx emissions of internal combustion engines. |
