  • Composition and method to improve the fuel economy of hydrocarbon fueled internal combustion engines
    Patent number: 9447351
    Abstract: A composition and method of improving the fuel economy of hydrocarbon fuel-powdered internal combustion engines. The composition contains a propoxylated and/or butoxylated reaction product of (a) at least one fatty acid, fatty acid ester, or mixture thereof and (b) a dialkanolamime. The composition is added to a hydrocarbon fuel in an amount of about 5 to about 2,000 ppm, based on the weight of the hydrocarbon fuel, to reduce friction within the engine and achieve an enhanced fuel economy.
