Abstract:
1. A diesel fuel composition for fuel injection comprising: a major amount of low sulfur diesel fuel selected from the group consisting of: biorenewable fuels, biodiesel fuel, gas-to-liquid (GTL) fuels, and synthetic fuels; and a reaction product of (a) a hydrocarbyl substituted dicarboxylic acid or anhydride, wherein the hydrocarbyl substituent is selected from the group consisting of a polyethylene radical, a branched polybutylene radical, and mixtures thereof, and (b) an amine compound or salt thereof of the formula wherein R is selected from the group consisting of a hydrogen and a hydrocarbyl group containing from about 1 to about 15 carbon atoms, and R 1 is selected from the group consisting of hydrogen and a hydrocarbyl group containing from about 1 to about 20 carbon atoms and wherein the reaction product is made at a temperature ranging from about 155° to about 200° C. at atmospheric pressure and contains at least one amino triazole group and wherein the reaction product is present in an amount ranging from 5 mg to 200 mg per Kg of fuel composition which amount is sufficient to improve the performance of diesel direct and/or indirect fuel injectors.
