Abstract
Abstract Normally liquid fuel compositions containing N-substituted morpholines of the formula O(CH.sub.2 CH.sub.2).sub.2 NR'YR" wherein R' is a divalent organic radical of at least one to about 30 carbon atoms, Y is --O--, --S--, ##EQU1## or --NR 3 --, R 3 is a hydrogen atom or a hydrocarbyl radical of at least one carbon atom and R" is a monovalent hydrocarbon radical of at least 20 carbon atoms, exhibit improved carburetor detergency and anti-icing properties. They also show intake system deposit inhibition. Particularly preferred embodiments of the invention are gasolines containing the above-described morpholines wherein Y is ##EQU2## R' is 1,3-propylene and R" is a hydrocarbyl group of at least about 40 carbon atoms.
