    • This invention relates to low-sulfur diesel fuels which are useful with diesel engines equipped with exhaust system particulate traps. These fuels contain an effective amount of an organometallic complex to lower the ignition temperature of exhaust particles collected in the trap. The sulfur content of these diesel fuels is no more than about 0.1% by weight, preferably no more than about 0.05% by weight. The organometallic complex is soluble or stably dispersible in the diesel fuel and is derived from (i) an organic compound containing at least two functional groups attached to a hydrocarbon linkage, and (ii) a metal reactant capable of forming a complex with the organic compound (i), the metal being any metal capable of reducing the ignition temperature of the exhaust particles. The functional groups include .dbd.X, --XR, --NR.sub.2, --NO.sub.2, .dbd.NR, .dbd.NXR, .dbd.N--R*--XR, ##STR1## --CN, --N.dbd.NR and --N.dbd.CR.sub.2 ; wherein X is O or S, R is H or hydrocarbyl, R* is hydrocarbylene or hydrocarbylidene, and a is a number (e.g., zero to about 10). Useful metals include Na, K, Mg, Ca, Sr, Ba, Ti, Zr, V, Cr, Mo, Mn, Fe, Co, Cu, Zn, B, Pb, Sb, and mixtures of two or more thereof. This invention is also directed to methods of operating a diesel engine equipped with an exhaust system particulate trap using the foregoing low-sulfur diesel fuels.
    • 本发明涉及用于配备有排气系统颗粒捕集器的柴油发动机的低硫柴油燃料。 这些燃料含有有效量的有机金属络合物以降低在捕集器中收集的废气颗粒的着火温度。 这些柴油的硫含量不超过约0.1重量%,优选不超过约0.05重量%。 有机金属络合物可溶于或稳定分散于柴油中,并衍生自(i)含有连接至烃键的至少两个官能团的有机化合物,和(ii)能够与有机化合物形成络合物的金属反应物 (i)中,金属是能够降低排气颗粒的着火温度的任何金属。 官能团包括= X,-XR,-NR2,-NO2,= NR,= NXR,= N-R * -XR,图像-CN,-N = NR和-N = CR2; 其中X为O或S,R为H或烃基,R *为亚烃基或亚烃基,a为数(例如0至约10)。 有用的金属包括Na,K,Mg,Ca,Sr,Ba,Ti,Zr,V,Cr,Mo,Mn,Fe,Co,Cu,Zn,B,Pb,Sb及其两种或更多种的混合物。 本发明还涉及使用前述低硫柴油燃料来操作配备有排气系统微粒捕集器的柴油发动机的方法。
