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:
The present invention relates to methods of improving the low temperature storage and performance properties of fatty acids and/or derivatives thereof, as well as compositions containing fatty acids and/or derivatives thereof having superior lower temperature storage and performance properties.
Abstract:
The present invention relates to novel quaternized ammonium salts of hydrocarbyl epoxides, to the preparation thereof and to the use thereof as a fuel additive and lubricant additive, such as, more particularly, as a detergent additive; for reducing or preventing deposits in the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.
Abstract:
Provided are additives of formula I for use in hydrocarbonaceous compositions, such as petroleum or liquid fuels: (I) wherein R1, R2, R3, R4, and R5 are as defined herein. The additives improve the corrosion resistance of the compositions. The additives also enhance the antimicrobial efficacy of any added biocides contained in such compositions.
Abstract:
A diesel fuel additive package, diesel fuel containing the additive and methods for operating an engine on the diesel fuel and additive. The fuel additive includes a reaction product of (a) a hydrocarbyl substituted dicarboxylic acid or anhydride, and (b) an amine compound or salt thereof of the formula wherein R is selected from hydrogen and a hydrocarbyl group containing from about 1 to about 15 carbon atoms, and R1 is selected from hydrogen and a hydrocarbyl group containing from about 1 to about 20 carbon atoms. The reaction product contains at least one amino triazole group. Component (2) of the additive is a hydrocarbyl succinimide dispersant. The additive also includes (3) a C2 to C10 alkyl alcohol; and (4) optionally, a lubricity additive. In the additive, a weight ratio of component (1) to component (2) in the fuel ranges from about 1:3 to about 1:5.
Abstract:
The present invention provides a fuel additive composition comprising (a) an alkoxylate detergent, (b) a fatty acid or derivative thereof, or mixtures thereof wherein the additive composition is soluble in the fuel where the fuel is a blend of hydrocarbonaceous and nonhydrocarbonaceous fuel with a nonhydrocarbonaceous fuel content of at least 50 percent by weight. Additionally, the present invention further provides for a fuel composition comprising such a additive composition and such a fuel. The present invention also provides for a method of operating an engine and a method of reducing deposits in a fuel system by using such an additive composition and fuel blend.
Abstract:
An additive composition for fuels such as diesel oil and fuel oil, used respectively for diesel engines and boilers of various types, containing a metal oxidation catalyst, in which the metal is iron, cerium, calcium, or their binary or ternary mixtures, an organic nitrate and a dispersing agent. The additive composition is able to reduce the formation of particulate emitted by diesel engines and boilers.
