Abstract: A method of cleaning up deposits in an indirect injection diesel engine, the method including combusting in the engine a diesel fuel composition having a quaternary ammonium salt additive; and optionally one or more further nitrogen-containing detergents; wherein the quaternary ammonium salt additive comprises the quaternised reaction product of a hydrocarbyl substituted succinic acid derived acylating agent and a compound able to react with said acylating agent and which includes a tertiary amine group; wherein each molecule of the hydrocarbyl substituted succinic acid derived acylating agent includes on average at least 1.2 succinic acid moieties.

Abstract: Fuel additive compositions having at least one acylated detergent, at least one Mannich detergent, and at least one polyether and/or polyetheramine. The acylated detergent may be the reaction product of a hydrocarbyl-substituted acylating agent and a nitrogen containing compound having at least one amino group, that may optionally be quaternizable, and at least one oxygen or nitrogen atom capable of reacting with the hydrocarbyl-substituted acylating agent. The compositions are useful for reducing the formation of carbonaceous deposits and/or cleaning carbonaceous deposits in an engine, such as a gasoline direct injection engine.

Abstract: A component and a system for mitigating coke formation during delivery of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. Tuning the zeta potential of the contact surface allows selective attraction and/or repulsion of coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid. A method of mitigating coke formation during delivery of a hydrocarbon fluid includes tuning a zeta potential of the contact surface of the component and injecting or circulating the hydrocarbon fluid through the system such that the contact surface selectively attracts and/or repels coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid.

Abstract: A fuel additive for fuel formulations comprising calcium sulfonates in an amount effective to limit or eliminate valve seat recession in engines utilizing such fuel formulations. The fuel additive may also include a detergent, particularly in an amount to enhance the VSR limiting effect of the calcium sulfonates. Also included are fuel formulations containing calcium sulfonates in a concentration effective to limit vale seat recession in engines utilizing the fuel formulations. Methods for treating VSR in piston engines are also provided.
