Abstract
Fuel consumption of an internal combustion engine being operated on a normally liquid hydrocarbon fuel of the gasoline boiling range is reduced by the addition to the fuel of a friction-reducing amount of a sulfurized fatty acid amide, ester or ester-amide of an oxyalkylated amine.
Claims6
As a composition of matter, a liquid hydrocarbon fuel for use in a spark-ignited internal combustion engine comprising a major amount of normally liquid hydrocarbon of the gasoline boiling range and a friction-reducing amount of an additive selected from sulfurized fatty acid esters, sulfurized fatty acid amides and sulfurized fatty acid ester-amides of an alkanol amine, said amine having the formula ##STR7## wherein R' is divalent aliphatic hydrocarbon radical containing 2-4 carbon atoms, n is an integer from 1 to 10, and R" is selected from hydrogen and the group --R'O).sub.n --H.
