摘要:
A fuel additive composition comprising:(a) an aromatic ester compound of the formula: ##STR1## or a fuel soluble salt thereof, wherein R is hydroxy, nitro or --(CH.sub.2).sub.x --NR.sub.5 R.sub.6, wherein R.sub.5 and R.sub.6 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms and x is 0 or 1;R.sub.1 is hydrogen, hydroxy, nitro or --NR.sub.7 R.sub.8, wherein R.sub.7 and R.sub.8 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms;R.sub.2 and R.sub.3 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms; andR.sub.4 is a polyalkyl group having an average molecular weight in the range of about 450 to 5,000; and(b) an aliphatic hydrocarbyl-substituted amine having at least one basic nitrogen atom, wherein the hydrocarbyl group has a number average molecular weight of about 400 to about 1,000.The fuel additive compositions of this invention are useful as fuel additives for the prevention and control of engine deposits.
