Description

FIELD OF THE INVENTION

[0001] This invention relates to a novel class of linked aromatic compounds that act as potent soot dispersants in lubricating oil compositions and lubricating oil compositions containing same. More specifically, the invention is directed to compounds that, when added to lubricating oil compositions provide soot dispersing performance in the industry standard “Mack T11” engine test, with reduced levels of additive nitrogen. The invention is further directed to a novel class of precursor compounds from which such soot dispersants can be derived.BACKGROUND OF THE INVENTION

[0002] Global Heavy Duty Diesel (HDD) engine emission legislation requires stepwise reductions in NO and particulate emissions between 1989 and 2009. Many diesel engine manufacturers are now incorporating into HDD engines an Exhaust Gas Recirculation (EGR) system that is operated in a condensing mode for at least a portion of the time the engine is operated (e.g., at least 10% of the time the engi...
