ABSTRACT:
A certain fuel-soluble nitrogen-hydrocarbyl-substituted nitrogenous composition has been found to display a previously unreported detergency in the internal combustion engine when present in fuels to the extent of 10-4,000 ppm. The nitrogenous composition is composed of a hydrocarbyl group bonded to a nitrogenous substrate. The hydrocarbyl substituent contains from 30 to about 400 carbon atoms, and the nitrogenous substrate is a carbamate, urea or amide.
