<p>ALKYLDIAMINOAMIDS OF FATTY ACIDS AS GASOLINE ADDITIVES Gasoline fuel compositions containing a dual additive comprising a composition having the general formula R-NHCH2CH2CH2NHCO-R' is improved by incorporation therewith of a second additive having the general formula R"OCH2CH2CH2NHCH2CH2 CH2NHCOR' in which R is an aliphatic hydrocarbon radical having 10-20 carbon atoms; R' is an aliphatic hydrocarbon radical having 9-19. carbon atoms and R" is an aliphatic hydrocarbon radical having '0-15 carbon atoms. The carburization systems of internal combustion engines operating on gasolines containing these additives remain low in harmful deposits of varnish scale which normally results from untreated fuel.</p> |
