Abstract: A fuel composition including a fuel and a fuel additive including a fuel soluble detergent selected from succinimide compounds of the Formula (I), Mannich detergents of the formulae (IIa), and amine detergents of the formulae (IIIa) and (IIIb). The fuel soluble detergents are derived from a specific class of ethylene-alpha olefin copolymers having an Mn of less than 5,000 g/mol, an ethylene unit content of more than 40 mol % to less than 90 mol %; a terminal unsaturation of 70 mol % or greater; at least 70 mol % of the unsaturation is terminal vinylidene, one or more tri-substituted isomers of the terminal vinylidene or any combination thereof, an average ethylene run length of less than 2.6; and wherein nC2,Actual>nC2,Statistical. Methods employing the fuel compositions for operating diesel and gasoline engines to reduce injector valve deposits, valve sticking and injector nozzle fouling, and a method for stabilizing a diesel fuel composition.

Abstract: A fuel additive concentrate for gasoline, a gasoline fuel containing an additive mixture, a method for reducing wear in an engine and in a fuel delivery system of a gasoline engine, and a method for improving injector performance. The additive concentrate includes an aromatic solvent and a mixture that contains (i) N,N-bis(2-hydroxyethyl)alkylamide, (ii) 2-((2-(bis(2-hydroxyethyl)amino)ethyl)amino)ethyl alkanoate and N-(2-(bis(2-hydroxyethyl)amino)ethyl)-N-(2-hydroxyethyl)alkylamide, and (iii) fatty acid ester(s) and amide(s) derived from a self-condensation product of diethanolamine (DEA) containing at least 3 amino groups. A weight ratio of (i) to (ii) to (iii) in the concentrate ranges from about 8:2:0 to about 2:5:3. The fuel additive mixture is substantially devoid of glycerin and remains fluid at a temperature down to about −20° C.

Abstract: The present disclosure relates to methods and fuel compositions for reducing or eliminating fuel injector deposits in high pressure gasoline engines. The fuel compositions include gasoline and a synergistic combination of a fuel injector clean-up mixture including a heterocyclic amine, diamine, or open chain derivative thereof and a hydrocarbyl substituted dicarboxylic anhydride derivative selected from a diamide, acid/amide, acid/ester, diacid, amide/ester, diester, and imide.

Abstract: Polyisobutylenes (PIBs) containing a high proportion of vinylidene end groups are generally favored over conventional PIBs because of their higher reactivity in reactions that are needed to prepare fuel and lubricant additives. However, detergent additives that have been prepared from conventional PIBs actually perform better than detergent additives prepared from high reactive PIBs. Specifically, detergent additives that were prepared from conventional PIB that was then enriched with tri- and tetra-PIB resulted in altered thermal stability and improved detergency of the resulting compound as compared to the structures which were created using a high proportion of vinylidene end groups.
