    • The invention concerns a method for supplying iron, via the fuel, to the particulate trap of a diesel engine exhaust in a form suitable for promoting trap regeneration. The method involves the addition to the fuel of a defined colloid of iron oxide. Combustion of this colloid produces iron-containing compounds, especially iron oxides, which collect in association with carbonaceous particulate matter in the particulate trap, and function to promote the combustion of this matter.The colloid in particular shows a lower level of associated deposit formation on the fuel injectors than the iron additives of the prior art. The method is thus particularly suitable for modern engines showing increased susceptibility to fuel injector deposits. The colloid also shows a balance of properties providing excellent suitability for use as an additive in fuels, and especially in diesel engine on-board dosing devices.
    • 本发明涉及一种通过燃料将铁供应到适于促进陷阱再生的形式的柴油发动机排气的颗粒捕集器的方法。 该方法包括加入定义的氧化铁胶体的燃料。 该胶体的燃烧产生含铁化合物,特别是氧化铁,其与颗粒捕集器中的碳质颗粒物质相结合,并且促进该物质的燃烧。 胶体特别表现出比现有技术的铁添加剂更低水平的燃料喷射器上相关的沉积物形成。 因此,该方法特别适用于显示对燃料喷射器沉积物的敏感性增加的现代发动机。 胶体还显示了在燃料中尤其是柴油发动机车载计量装置中特别适合用作燃料添加剂的性能的平衡。
