    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: A liquid composition is described which comprises (A) a major amount of a fluorine containing hydrocarbon containing one or two carbon atoms, and (B) a minor amount of a soluble organic lubricant free of acetylenic and aromatic unsaturation and comprising at least one sulfone or sulfoxide characterized by the formulae R1(R2)SO2 (I) R1(R2)SO (II) wherein R1 and R2 are each independently hydrocarbyl groups, -R3O(O)CR4, -NR4R5 or -R3NR4R5 groups wherein R3 is a hydrocarbylene group, and R4 and R5 are each independently hydrocarbyl groups, or R1 and R2 are hydrocarbylene groups joined together to form a cyclic moiety including the sulfur atom, or R1 is a hydrocarbyl group and R2 is OR6 wherein R6 is a hydrocarbyl group. The liquid compositions exhibit excellent thermal stability and are useful particularly as refrigeration liquids in refrigerators and air-conditioners including auto, home and industrial air-conditioners.

    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.
