Abstract:
A polymeric surfactant obtained by the reaction of: (i) a polyolefin oligomer functionalized with at least one group deriving from a dicarboxylic acid, or a derivative thereof; and (ii) a polyoxyalkylene of linear oxyalkylene units. The polyoxyalkylene is linked to a long-chain alkyl group optionally containing one or more ethylenic unsaturations. The polymeric surfactant may be utilized to stabilize a fuel of an emulsion between water and a liquid hydrocarbon. The fuel has high stability over time, without forming carbonaceous deposits which adhere to metal surfaces.

Abstract:
A fuel oil composition comprising a major amount of fuel oil and a polymeric additive of Mn 1,000 to less than 3,000. The polymeric additive comprises the condensation reaction product of an aliphatic aldehyde having 1 to 4 carbon atoms and a mixture of alkylphenols comprising a major amount of a monoalkylphenol with more than 10 to less than 35 mole % of a dialkylphenol. The alkyl groups of the phenol have 1 to 20 carbon atoms. The polymeric additive is useful for improving the low temperature flow properties of a fuel oil.
Abstract:
An emulsifying composition which includes an ethoxylated alkylphenol, a fatty acid amide, naphtha and oleic acid. The composition is used for emulsifying fuel and water mixtures in internal combustion engines, open flame burners (boilers) or the like. Preferably the composition includes one part polyoxyethylene-nonylphenol, two parts coconut diethanolamide, two parts heavy naphtha and one part oleic acid, by volume. The invention also extends to a hydrocarbon fuel including a composition in accordance with the invention and to a method of forming a hydrocarbon fuel and water emulsion including the composition.
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:
A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkylated amine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkylated amine, such as n-butylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy. Moreover, the use of the friction modifier (a) in combination with a detergent package permits increased fuel efficiency to be obtained without increasing the incidence of IVD deposits in combustion engines running on a fuel modified with the additive concentrate.
