A motor fuel additive composition comprises a mixture of: (a) from about 5 to about 50 weight percent, based upon the total weight of the additive, of a detergent component selected from the group consisting of (i) a reaction product of a substituted hydrocarbon and an amino compound, and (ii) a polybutylamine or polyisobutylamine; and (b) a fuel conditioner component comprising (i) from about 2 to about 50 weight percent, based upon the total weight of the additive, of a polar oxygenated hydrocarbon compound and (ii) from about 2 to about 50 weight percent, based upon the total weight of the additive, of an oxygenated compatibilizing agent. The fuel conditioner component may additionally comprise a hydrophilic separant, an aromatic hydrocarbon, or mixtures thereof. Additionally, in some cases the hydrophilic separant may also act as the compatibilizing agent. The additive may also additionally comprise a carrier oil or fluidizer. The additive is prepared by mixing together the detergent and fuel conditioner components, and is advantageous in that the detergent and fuel conditioner components synergistically interact to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby inhibiting engine ORI.
一种汽车燃料添加剂组合物包括以下物质的混合物(a) 以添加剂总重量为基准,约 5%至约 50%的去污剂组分,该组分选自以下 组别:(i) 取代的碳氢化合物和氨基化合物的反应产物;(ii) 聚丁胺或 聚异丁胺;(b) 燃料调节剂组分,包括:(i) 极性含氧烃化合物,占添加剂总重量的约 2%至约 50%;(ii) 含氧相容剂,占添加剂总重量的约 2%至约 50%。燃料调节剂组分还可包括亲水分离剂、芳香烃或它们的混合物。此外,在某些情况下,亲水分离剂也可用作相容剂。添加剂还可额外包含一种载体油或流化剂。添加剂是通过将清洁剂和燃油改良剂成分混合在一起制备而成的,其优点在于清洁剂和燃油改良剂成分可协同作用,减少燃油进气系统沉积物的形成和燃烧室沉积物的形成,从而抑制发动机ORI。
