    Abstract: This invention relates to copper-containing organometallic complexes, and to concentrates and diesel fuels containing said complexes. The diesel fuels are useful with diesel engines equipped with exhaust system particulate traps. The copper-containing organometallic complex is used for lowering the ignition temperature of exhaust particles collected in the trap. The copper-containing 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 copper-containing metal reactant capable of forming a complex with the organic compound (i). The functional groups are =X, -XR, -NR., -NO., =NR, =NXR, =N-R*-XR, -CN, -N=NR or -N=CR.; 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). The copper can be combined with one or more metals selected from the group consisting Na, K, Mg, Ca, Sr, Ba, V, Cr, Mo, Fe, Co, Zn, B, Pb, Sb, Ti, Mn and Zr. This invention is also directed to methods of operating a diesel engine equipped with an exhaust system particulate trap using the foregoing diesel fuel.

    Abstract: 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, -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.

    Abstract: This invention relates to copper-containing aromatic Mannich complexes, and to concentrates and diesel fuels containing said complexes. The diesel fuels are useful with diesel engines equipped with exhaust system particulate traps. The copper-containing aromatic Mannich complex is used for lowering the ignition temperature of exhaust particles collected in the trap. The copper-containing aromatic Mannich complex is obtainable by contacting either component (A) or component (B) with component (C); component (A) being at least one compound represented by the general formula wherein R is an alkyl group of 1 to about 6 carbon atoms, and R is a saturated or unsaturated aliphatic hydrocarbyl group of about 16 to about 20 carbon atoms; component (B) being a mixture of (B)(I) and (B)(II), component (B)(I) being at least one compound represented by the general formula wherein R is an alkyl group of about 9 to about 18 carbon atoms, R is an alkylene group of 1 to about 4 carbon atoms, and R is a saturated or unsaturated aliphatic hydrocarbyl group of about 16 to about 20 carbon atoms; and component (B)(II) is at least one compound represented by the formula wherein R and R are independently alkyl groups of about 9 to about 18 carbon atoms, and R is an alkylene group of 1 to about 4 carbon atoms; and component (C) is at least one copper reactant.d re

    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 =X, -XR, -NR2, -NO2, =NR, =NXR, =N-R*-XR, -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, 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.
