Abstract
A method for cleaning engine fuel injectors which includes connecting the injectors to a canister containing an aerosol formulation comprising a liquid cleaner and a compressed air propellant, and thereafter forcing the cleaner through the injectors to remove contaminating deposits therefrom. The compressed air serves both as a combustion oxidant, as well as the propellant for the cleaner. In addition to including a material capable of dissolving injector contaminants, the cleaner may include as components thereof detergents, dispersants, detergent and dispersant solvents, lubricants, and other substances useful in cleaning processes.
