This invention relates to combinations of (A) organometallic complexes and (B) antioxidants. These combinations can be used in diesel fuels for operating diesel engines equipped with exhaust system particulate traps. The combination of (A) and (B) is useful in lowering the ignition temperature of exhaust particles collected in the trap. The organometallic complex (A) 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 =X, -XR, -NR2, -NO2, =NR, =NXR, =N-R*-XR, α, β, γ, -CN, -N=NR and -N=CR2; 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, V, Cr, Fe, Co, Cu, Zn, Pb, Sb, and mixtures of two or more thereof. This invention is also directed to concentrates and diesel fuels, and to methods of operating a diesel engine equipped with an exhaust system particulate trap.

Diesel fuels containing organometallic complexes

This invention relates to 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 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 =X, -XR, -NR2, -NO2, =NR, =NXR, =N-R*-XR, α, β, γ, -CN, -N=NR and -N=CR2; 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, V, Cr, Mo, 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 diesel fuel.

Low-sulfur diesel fuels containing organometallic complexes

Carburants diesel à faible teneur en soufre qui sont utiles pour des moteurs diesel équipés de pièges pour matière particulaire dans le système d'échappement. Lesdits carburants contiennent une quantité efficace d'un complexe organo-métallique destiné à baisser la température de calcination des particules d'échappement recueillies dans le piège. La teneur en soufre de ces carburants diesel ne dépasse pas environ 0,1 % en poids, et de préférence environ 0,05 % en poids. Le complexe organo-métallique est soluble ou dispersible de manière stable dans ledit carburant diesel et est dérivé (1) d'un composé organique contenant au moins deux groupes fonctionnels attachés à une liaison hydrocarbure et (ii) d'un réactant métallique capable de former un complexe avec le composé organique (i), ledit métal étant tout métal capable de réduire la température de calcination des particules d'échappement. Les groupes fonctionnels comprennent =X, -XR, -NR2, -NO2, =NR, =NXR, =R-R*-XR, (I), (II), (III), -CN-N=NR et -N=CR2 dans lesquels X est O ou S, R est H ou hydrocarbyle, R* est hydrocarbylène ou hydrocarbylidène et a est un nombre (soit, zéro à environ 10).
