First Claim
Patent Images
1. A fuel composition comprising a hydrocarbon boiling in the gasoline range and from 10 to 10,000 parts per million of a polyamino alkenyl or alkyl succinimide wherein one or more of the nitrogens of the polyamino moiety is substituted with ##STR22## wherein W is oxygen or sulfur;
- X is oxygen, sulfur, or >
NR5 wherein R5 is hydrogen or alkyl of from 1 to 20 carbon atoms; and
R4 is an alkylene group of from 2 to 5 carbon atoms or an alkylene group of from 2 to 5 carbon atoms substituted with 1 to 3 alkyl groups of from 1 to 2 carbon atoms each with the proviso that both W and X are not both oxygen.

Abstract
Disclosed herein are additives which are useful as dispersants and detergents in lubricating oils. In particular, this invention is directed toward polyamino alkenyl or alkyl succinimides which have been modified by treatment with a compound of the formula: ##STR1## wherein W is oxygen or sulfur; X is oxygen, sulfur or R5 N< wherein R5 is hydrogen, and alkyl of from 1 to 20 carbon atoms; and R4 is an alkylene group of from 2 to 5 carbon atoms or an alkylene group of from 2 to 5 carbon atoms substituted with from 1 to 3 alkyl groups of from 1 to 2 carbon atoms each with the proviso that both W and X are not both oxygen. The modified polyamino alkenyl or alkyl succinimides of this invention have been found to possess dispersancy and detergency in lubricating oils. These modified succinimides are also useful as dispersants and detergents in fuels.
