    Abstract: The present invention relates to innovative quaternized polyetheramines and to the preparation thereof. The present invention further relates to the use of these compounds as a fuel and lubricant additive. More particularly the invention relates to the use of these quaternized nitrogen compounds as a fuel 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. The invention also provides additive packages comprising these polyetheramines, and fuels and lubricants additized therewith. The invention further relates to the use of these quaternized nitrogen compounds as an additive for gasoline fuels, especially for improving the intake system cleanliness of gasoline engines.

    Abstract: Use of a tertiary hydrocarbyl amine with Ci- to C2o-hydrocarbyl residues, the overall number of carbon atoms not exceeding 30, as an additive in gasoline for reducing injector nozzle fouling in direct injection spark ignition engines. A fuel additive composition essentially comprising nitrogen-containing dispersants, carrier oils, the above tertiary hydrocarbyl amines and optionally friction modifiers. A fuel composition comprising a major amount of gasoline and a minor amount of the above fuel additive composition.

    Abstract: Disclosed are polyisobutene amines of general formula R1CH2-NR2R3 in which R1 represents a polyisobutyl radical that is derived from isobutene and up to 20 percent by weight of n-butene and has a number average molecular weight Mn ranging from 600 to 770, and R2 and R3 independently represent hydrogen, a C1-C18 alkyl radical, C2-C18 alkenyl radical, C4-C18 cycloalkyl radical, C1-C18 alkyl aryl radical, hydroxy-C1-C18 alkyl radical, poly(oxyalkyl) radical, polyalkylene polyamine radical, or polyalkylene imine radical, or a heterocyclic ring along with the nitrogen atom to which they are bonded. Said polyisobutene amines are suitable as detergents in gasolines, reduce valve stickiness, and improve compatibility of the detergents with flotation oils and compatibility in fuel compositions containing a mineral fuel percentage and C1-C4 alkanols.

    Abstract: A fuel additive composition includes a polyalkenylsuccinimide, a mono or polyfunctional polyisobutene amine, and a carrier oil selected from the group of mineral oils, polyethers, polyetheramines, esters, and combinations thereof. The polyalkenylsuccinimide includes the reaction product of a hydrocarbyl dicarboxylic acid producing reaction intermediate and a nucleophilic reactant. The hydrocarbyl dicarboxylic acid producing reaction intermediate includes the reaction product of a polyolefin comprising C2 to C18 olefin units and having a number average molecular weight (Mn) of about 500 to 5,000 g/mol and a C4 to C10 monounsaturated acid reactant. The hydrocarbyl dicarboxylic acid producing reaction intermediate includes from 0.5 to 10 dicarboxylic acid producing moieties per molecule of the polyolefin. The nucleophilic reactant is selected from the group of amines, alcohols, amino alcohols, and combinations thereof.
