  • Fuel additive compositions for diesel engine equipped with a particulate trap
    Patent number: 7585336
    Abstract: A fuel additive composition comprising a solution or dispersion of an oil soluble metal carboxylate or metal complex derived from a compound of the formula: where R1, R2, R3 and R4 represent hydrogen or a hydrocarbyl having 1-30 carbon atoms (C1-C30), but at least two of R1, R2, R3 or R4 are C1-C30 hydrocarbyl; R5 is a hydrocarbyl having 1 to 120 carbon atoms and m and n may each be zero or an integer such that the total number of carbon atoms in the carboxylate is not more than 125.
