Fuel additive compositions containing an aliphatic amine, a polyolefin and an aromatic ester

摘要

A fuel additive composition comprising: (a) a fuel-soluble aliphatic hydrocarbyl-substituted amine having at least one basic nitrogen atom wherein the hydrocarbyl group has a number average molecular weight of about 700 to 3,000; (b) a polyolefin polymer of a C2 to C6 monoolefin, wherein the polymer has a number average molecular weight of about 350 to 3,000; and (c) an aromatic di- or tri-carboxylic acid ester of the formula: <IMAGE> wherein R is an alkyl group of 4 to 20 carbon atoms, and x is 2 or 3.
