    Abstract: Title: METAL SALTS USEFUL AS ADDITIVES FOR FUELS AND LUBRICANTS This invention relates to metal salts of the general formula Ay-My+ (I) wherein M represents one or more metal ions, y is the total valence of all M and A represents one or more anion containing groups having a total of about y individual anionic moieties and each anion containing group is a group of the formula (II) wherein T is selected from the group consisting of (V) or (VI) wherein each R5 is independently selected from O- and OR6 wherein R6 is H or alkyl and each t is independently 0 or 1, wherein each Ar is independently an aromatic group of from 4 to about 30 carbon atoms having from 0 to 3 optional substituents selected from the group consisting of polyalkoxyalkyl, lower alkoxy, nitro, halo or combinations of two or more of said optional substituents, or an analog of such an aromatic group, wherein T is as hereinbefore defined, each R is independently alkyl, alkenyl or aryl having at least 8 carbon atoms, R is H or a hydrocarbyl group, R2 and R3 are each independently H or a hydrocarbyl group, each m is independently an integer ranging from 1 to about 10, x ranges from 0 to about 8, and each Z is independently OH, (OR4)bOH or O- wherein each R4 is independently a divalent hydrocarbyl group and b is a number ranging from 1 to about 30 and c ranges from 0 to about 3 with the proviso that when t in Formula (II) = 0, or when T is Formula (V), then c is not O provided that the sum of m, c and t does not exceed the unsatisfied valences of the corresponding Ar. Additive concentrates for preparing lubricants and fuels other than two-cycle engine lubricants and fuel compositions as well as lubricating compositions and fuel compositions other than those for two-cycle engines are also disclosed.

    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.
