Abstract:
A fuel additive for a gasoline fuel composition, a gasoline fuel composition and a method for reducing wear in a gasoline delivery system of an engine. The fuel additive includes a synergistic mixture of (i) N,N-bis(hydroxyalkyl)-alkylamine, and (ii) an amide reaction product of a hydroxy acid, hydroxy ester, or lactone and an amine or ether amine, wherein a weight ratio of (i) to (ii) in the synergistic mixture ranges from about 1:5 to about 5:1.
Abstract:
A diesel fuel additive for use in association with bio-diesel fuel and/or petroleum derived diesel fuel having one or more solvent(s) and one or more pour-point depressant(s), wherein the pour-point depressant(s) include a polyglycerol ester, such as polyglycerol polyricinoleate and/or polyglycerol esters of mixed fatty acids. Augmentive agents may include ethylene vinyl acetate and/or polyethylene vinyl acetate.
Abstract:
Nitroparaffins are added to gasoline together with synthetic lubricants of the ester type (e.g. synthetic jet turbine oil) and are used as fuel in glow engines, jet engines and internal combustion engines in general to improve combustion efficiency, especially by lowering fuel consumption while increasing the output and providing cleaner burning.
Abstract:
AN ADDITIVE HAVING DETERGENCY AND LUBRICITY PROPERTIES FOR INCORPORATION IN PETROLEUM HYDROCARBON AND PETROLEUM HYDROCARBON COMOSITIONS CONATINING SAID ADDITIVE. THE ADDITIVE IS THE CONDENSATION PRODUCT OF A POLYETHERPOLYESTER POLYOL CONTAINING FROM 2 TO ABOUT 12 HYDROXYL GROUPS AND A MONOCARBOXYLIC ACID WHEREIN ABOUT 85100% OF THE HYDROXYL GROUPS OF THE POLYOL ARE ESTERIFIED BY CONDENSATION WITH THE MONOCARBOXYLIC ACID. THE ADDITIVE IS GENERALLY INCORPORATED IN HYDROCARBON FUELS AND HYDROCARBON LUBRICATING OILS, BUT ITS GREATEST UTILITY IS IN HYDROCARBON LUBRICATING OILS. THE PREFERRED LUBRICATING OIL COMPOSITION IS A 2-CYCLE ENGINE OIL COMPROSING A MAJOR PROPORTION OF A HYDROCABON LUBRICATNG OIL AND A MINOR PROPORTION OF THE ADDITIVE OF THE INVENTION.
Abstract:
An additive for low-sulfur mineral oil distillates having improved cold flowability and paraffin dispersancy, comprising at least one ester of an alkoxylated polyol and at least one polar nitrogen-containing paraffin dispersant.
Abstract:
The low temperature properties of a blend of biofuel and petroleum-based fuel oil are improved by the addition of an ethylene-unsaturated ester copolymer, or a comb polymer, or a polar N compound, or a compound having at least one linear alkyl groups connected to a non-polymeric organic residue.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are the oligomeric/polymeric reaction products of aromatic anhydrides and epoxides (or their corresponding acid/diol equivalents), with optional termonomers.
Abstract:
An additive having detergency and lubricity properties for incorporation in petroleum hydrocarbon and petroleum hydrocarbon compositions containing said additive. The additive is the condensation product of a polyetherpolyester polyol containing from 2 to about 12 hydroxyl groups and a monocarboxylic acid wherein about 85-100 percent of the hydroxyl groups of the polyol are esterified by condensation with the monocarboxylic acid. The additive is generally incorporated in hydrocarbon fuels and hydrocarbon lubricating oils, but its greatest utility is in hydrocarbon lubricating oils. The preferred lubricating oil composition is a two-cycle engine oil comprising a major proportion of a hydrocarbon lubricating oil and a minor proportion of the additive of this invention.
Abstract:
A middle distillate having a maximum um sulfur content of 0.05% by weight and containing fatty acid esters of alkoxylated polyols having at least 3 OH groups (A) and also at least one cold flow improver (B). The cold flow improver includes at least one copolymer of ethylene and one or more ethylenically unsaturated carboxylic esters having an ethylene portion of from 60 to 90 mol %.
