  • Low-sulfur diesel fuels containing organo-metallic complexes
    Patent number: 5518510
    Abstract: 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 mount 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.
