Abstract: The present disclosure provides an amide friction modifier which exhibits improved low temperature compatibility with fuel. The amide friction modifier is formed from a hyper-branched fatty acid and an amine. Methods to reduce the frictional property of a fuel and a fuel composition including the amide friction modifier are also disclosed.

Abstract: New, highly effective Mannich detergents for use in hydrocarbon fuels are described which reduce engine deposits in spark and compression ignition internal combustion engines. They are Mannich condensation reaction products obtained from reacting: (i) a polyamine having a sterically-hindered primary amino group, (ii) a hydrocarbyl-substituted hydroxyaromatic compound, and (iii) an aldehyde. These Mannich detergent compounds may be dispersed in a liquid carrier to provide a fuel additive concentrate for hydrocarbon engine fuels which effectively control engine deposit formation in intake valves and also other engine regions such as port fuel injectors and combustion chambers.

Abstract: There is disclosed a Mannich reaction product and a reaction to create a Mannich reaction product prepared from an amino alcohol, a high molecular, weight hydroxy aromatic compound, and an aldehyde. Compositions comprising a hydrocarbon fuel and the reaction product are also disclosed.

Abstract: A fuel additive composition including a Mannich product, a polyetheramine, and a friction modifier is disclosed. Also, disclosed are a fuel composition comprising the fuel additive composition, an engine combusting the fuel composition, and a method of preventing and/or forming deposits in an engine.

Abstract: A fuel composition and methods for using it for controlling deposit formation in a spark-ignition internal combustion engine, such as a direct injection engine, comprising a spark-ignition fuel, a detergent, and a deposit inhibitor compound.

Abstract: An improved process for preparing a Mannich product employs an intermediate or pre-formed triazine. The product is useful as a detergent in fuel compositions. The fuel compositions containing the Mannich product are useful for controlling intake valve deposits in engines.

Abstract: A method and composition for suppressing coal dust include a metal-containing compound, such as an organo-manganese, that provides the additional benefit of being a combustion improver. The organometallic compound is mixed with any appropriate dust suppressant liquid. The organometallic compound may include methylcyclopentadienyl manganese tricarbonyl.

Abstract: The invention provides a device containing an ion-exchange resin to which is chemically bound a fuel additive material which will gradually be released from the resin into a fuel in which the device is placed.

Abstract: The present invention relates to a method for controlling deposit formation on intake valves while simultaneously exhibiting “no-harm” on combustion chamber deposits in engines by combusting in the engine a fuel composition containing an ethanol content greater than about 5% by volume and a Mannich-base detergent additive. The invention also relates to a high ethanol-content gasoline fuel containing a Mannich-base detergent in an amount effective for improving the reduction of intake valve deposits resulting from the combustion in an engine of the fuel.

Abstract: Optical components and highly-polished metal surfaces are cleaned with a first composition comprising 1,1,2-trichloro-1,2,2-trifluoroethane, isopropyl alcohol, dimethylformamide and 2-ethoxyethanol; then, while the surface is still wet with said first composition, a second composition, comprising at least about 85% 1,1,2-trichloro-1,2,2-trifluoroethane and containing less than 10 ppm of non-volatile residues, is applied to rinse the surface; and the surface is permitted to dry.
