FUEL ADDITIVE MIXTURE PROVIDING RAPID INJECTOR CLEAN-UP IN HIGH PRESSURE GASOLINE ENGINES

摘要

The present disclosure relates to methods and fuel compositions for reducingoreliminating fuel injector deposits in high pressure gasoline engines. The fuelcompositionsinclude gasoline and a synergistic combination of a fuel injector clean-upmixture including aheterocyclic amine, diamine, or open chain derivative thereof and ahydrocarbyl substituteddicarboxylic anhydride derivative selected from a diamide, acid/amide,acid/ester, diacid,amide/ester, diester, and imide.
