The present invention relates to the field of fuel additives for fuel compositions and more particularly to a composition that can be used as a friction modifier, and its preparation process. More particularly, the present invention concerns a composition comprising at least one fatty acid amide of diethanolamine (DEA) and at least one fatty acid ester and/or amide of DEA oligomer, and it preparation process.

Composition useful as friction modifier

A fuel composition, a lubricant composition, and methods for reducing friction or wear of moving parts. The fuel composition includes gasoline and from about 10 to about 500 ppm by weight of a dialkylaminoalkanol of the formula R(R)NCHCH(R)R. The lubricant composition includes base oil of lubricating viscosity and from about 0.05 to about 5.0 weight percent of a dialkylaminoalkanol of the formula R(R)NCHCH(R)R. In the above formulas wherein Ris an alkyl group or a hydroxy alkyl group containing from 8 to 50 carbon atoms; Ris an alkyl group containing from 1 to 4 carbon atoms; Ris selected from H and OH; and Ris selected from H, an alkyl group containing from 1 to 4 carbon atoms, and CHOH and wherein at least one of Rand Rcontains a hydroxyl group and provided that when Ris a hydroxyalkyl group, Ris OH and Ris CHOH.

Dialkylaminoalkanol friction modifiers for fuels and lubricants

A fuel additive concentrate for gasoline, a gasoline fuel containing an additive mixture, a method for reducing wear in an engine and in a fuel delivery system of a gasoline engine, and a method for improving injector performance. The additive concentrate includes an aromatic solvent and a mixture that contains (i) N,N-bis(2-hydroxyethyl)alkylamide, (ii) 2-((2-(bis(2-hydroxyethyl)amino)ethyl)amino)ethyl alkanoate and N-(2-(bis(2-hydroxyethyl)amino)ethyl)-N-(2-hydroxyethyl)alkylamide, and (iii) fatty acid ester(s) and amide(s) derived from a self-condensation product of diethanolamine (DEA) containing at least 3 amino groups. A weight ratio of (i) to (ii) to (iii) in the concentrate ranges from about 8:2:0 to about 2:5:3. The fuel additive mixture is substantially devoid of glycerin and remains fluid at a temperature down to about &#x2212;20&#xb0; C.
