    • Use of a fuel composition comprising a major amount of a fuel suitable for use in a compression-ignition engine, which fuel comprises one or more hydrocarbon components boiling within the diesel boiling range, at least one of which hydrocarbon components has been treated with a metal adsorbing or absorbing material in a different physical phase from the hydrocarbon component(s), preferably to reduce the level of at least one metal, more preferably the level of at least one heavier metal, most preferably the level of copper and/or iron and/or zinc, in said at least one hydrocarbon component, said treatment including physical separation of the hydrocarbon component from the metal adsorbing or absorbing phase, for the purpose of reducing subsequent formation of deposits, preferably combustion related deposits, during engine operation in a compression- ignition engine into which the fuel composition is introduced and/or of removing from the engine previously incurred deposits. Preferably the level of deposits in the engine after engine operation with said fuel composition in the engine is lower than the level of deposits in the engine after engine operation with an alternative fuel composition in the engine, said alternative fuel composition having essentially the same characteristics as said fuel composition but the hydrocarbon components of which have not been treated with said metal adsorbing or absorbing material.
    • 使用包含主要量的适用于压燃式发动机的燃料的燃料组合物,该燃料包括在柴油沸程范围内沸腾的一种或多种烃组分,其中至少一种烃组分已用金属处理 吸附或吸收与烃组分不同物理相的材料,优选降低至少一种金属的含量,更优选至少一种较重金属的含量,最优选铜和/或铁的含量,以及 /或锌,在所述至少一种烃组分中,所述处理包括烃组分与金属吸附或吸收相的物理分离,以便在发动机操作期间在压缩中减少随后的沉积物形成,优选燃烧相关沉积物 - 点燃发动机,其中引入燃料组合物和/或从发动机中除去先前发生的沉积物。 发动机运转后发动机运转时发动机中沉积物的沉积物水平低于在发动机运转后发动机运转时的发动机沉积物水平,所述替代燃料组合物具有与 所述燃料组合物,但其烃组分未用所述金属吸附材料或吸收材料处理。
