  • Polyalkylene succinimide deposit control additives and fuel compositions containing same
    Patent number: 5114435
    Abstract: Deposits on intake valves in gasoline internal combustion engines are reduced by an additive for fuel compositions comprising a mixture of (1) a polyalkylene succinimide, (2) a polyalkylene and (3) a mineral oil. The invention also comprises a fuel composition made up of a major amount of liquid hydrocarbon fuel such as gasoline or diesel and a minor amount of the aforesaid mixture. In still another aspect the invention comprises a method for removing and/or preventing engine deposits which adversely affect the performance of gasoline powered engines by running the engine with a fuel containing an effective amount of the previously described mixture.
