Abstract: An automotive lubricant composition comprising a base fluid and an ashless polymeric dispersant is claimed. The ashless polymeric dispersant has a number average molecular weight of between 500 and 10,000 and comprises a polar tall group which itself comprises a polymeric backbone of 2 to 30 monomeric repeat units, each repeat unit comprising a hydrocarbon chain functionalised by the presence of at least one electronegative element or moiety, the tail group being linked to a polar head group which comprises a polar moiety selected from at least one of acid, ester, amide or alcohol moieties. The dispersant has good dispersancy properties, when used as a sole dispersant or in combination with other dispersants. It provides enhanced seal resistance and has good oxidative stability in automotive applications as compared to current commercial products. Furthermore the low temperature viscosity of the automotive lubricant composition with the designed dispersant is superior to that of a composition with current commercial dispersants and the designed dispersant does not react with ZDDP and reduce the antiwear capabilities of ZDDP.

Abstract: Exhaust emissions resulting from the combustion of hydrocarbon fuels in compression ignition engines may be reduced using a homopolymer that may be polyisobutylene, polypropylene, and/or hyperbranched polyalpha-olefins. The homopolymer may have a molecular weight of from about 1600 to about 275,000. Optionally, an alkyl nitrate such as 2-ethylhexylnitrate (2EHN), and/or a peroxide, such as hydrogen peroxide, may also be used together with the homopolymer. Both NOx and particulate matter emissions (PM) may be reduced using ppm quantities of the additive compositions; alternatively, NOx emissions may be lowered or reduced while PM emissions do not substantially increase.
