摘要： A diesel fuel composition, and a method for removing the injector deposits in a diesel engine using the same are provided to reduce the generating rate of the deposits in a modern diesel engine fuel injector, effectively. A diesel fuel composition comprises a major amount of diesel fuel, a minor amount of at least one metal compound, and a minor amount of detergent additive. The detergent additive is used to remove or reduce injector deposits in a diesel engine operated by diesel fuel containing a minor amount of a metal-containing compound. The detergent additive comprises two kinds of compounds expressed by different chemical formulas. The diesel engine has a fuel injector having a plurality of spray-holes, wherein each of the spray-holes has an inlet and an outlet. The fuel injector has one or more of the following characteristics: a spray-hole which is tapered such that the inlet diameter is larger than the outlet diameter, a spray-hole having an outlet diameter of 0.10 mm or less, a spray-hole of which an inner edge of the inlet is rounded, six or more spray-holes, an operating tip temperature over 250°C.
摘要翻译：提供了一种柴油燃料组合物和用于使用该柴油发动机的柴油发动机中的喷射器沉积物的去除方法，以有效地降低现代柴油发动机燃料喷射器中沉积物的产生速率。柴油燃料组合物包含主要量的柴油燃料，少量的至少一种金属化合物和少量洗涤剂添加剂。洗涤剂添加剂用于去除或减少由含有少量含金属化合物的柴油燃料操作的柴油发动机中的喷射器沉积物。洗涤剂添加剂由不同化学式表示的两种化合物组成。柴油发动机具有燃料喷射器，其具有多个喷射孔，其中每个喷射孔具有入口和出口。燃料喷射器具有以下特征中的一个或多个：喷射孔，其锥形，使得入口直径大于出口直径，喷口孔的出口直径为0.10mm以下，喷孔为其入口的内边缘是圆形的，六个或更多个喷孔，操作尖端温度超过250℃。
