FRICTION MODIFIER ALKOXYAMINE SALTS OF CARBOXYLIC ACIDS AS ADDITIVES FOR FUEL COMPOSITIONS AND METHODS OF USE THEREOF

摘要

A friction modifier comprises alkoxylated amine salt or etheramine salt of saturated carboxylic acid. Independent claims are also included for: (a) an additive concentrate composition comprising saturated carboxylic acid salt of alkoxylated amine, and detergent package containing detergent and carrier fluid; (b) a fuel composition comprising combustible fuel and additive concentrate (50-2500 ppm); (c) a method of combusting a fuel by combining a fuel which is combustible in a gasoline engine having intake valves with a fuel additive concentrate; and (d) a method of increasing the fuel efficiency in a gasoline combustion engine by combusting a gasoline fuel comprising fuel boiling in the gasoline boiling range, and saturated carboxylic acid salt of alkoxylated amine or etheramine.
