    • Coking in and around the injector nozzles of indirect injection compression ignition engines is reduced by means of distillate fuel with which has been blended suitable concentrations of (i) organic nitrate ignition accelerator, and (ii) an additive selected from the group consisting of fuel-soluble aliphatic hydrocarbon-substituted succinimide, succinamide and mixtures thereof. The aliphatic hydrocarbon group contains about 12-36 carbon atoms and is derived from an isomerized straight chain .alpha.-olefin.Also described are additive mixtures of (i) and (ii) for use in distillate fuels in amounts sufficient to reduce the coking tendencies of such fuels when used in the operation of indirect injection compression ignition engines.
    • 间接喷射压缩点火发动机的喷射器喷嘴内和周围的焦化通过混合了适当浓度的(i)有机硝酸盐点火促进剂的馏出燃料和(ii)选自燃料 - 可溶性脂族烃取代的琥珀酰亚胺,琥珀酰胺及其混合物。 脂族烃基含有约12-36个碳原子,衍生自异构化的直链α-烯烃。 还描述了用于馏出燃料中的(i)和(ii)的添加剂混合物,其量足以在间接注射压燃式发动机的操作中使用时降低这种燃料的焦化倾向。
