Abstract
The present invention provides friction-modifying fuel additives and fuel compositions including an alkanolamine, which are effective for enhancing engine performance wherein the additive is free of esters or the ratio of amides to esters is greater than 1.4 to 1 and methods for making and using the same.
Claims59
A fuel additive for providing friction modification in an internal combustion engine comprising a friction modifying amount of alkanolamides, wherein the additive is free of esters or the molar ratio of amides to esters within said additive is greater than 1.4 to 1.
A fuel composition comprising
- a) a major amount of an internal combustion engine hydrocarbon fuel;
- and
- b) a minor amount of a fuel additive comprising a friction modifying amount of alkanolamides, wherein the additive is free of esters or the molar ratio of amides to esters within said additive is greater than 1.4 to 1.
A method of making a fuel additive comprising:
- a) reacting a fatty acid, ester or oil with an alkanolamine, thereby producing one or more reaction products useful as a fuel additive, wherein the additive is free of esters or the ratio of amides to esters within said reaction product is greater than 1.4 to 1.
