Abstract
Compositions that include a detergent composition and an active metal compound are described wherein the detergent composition includes a quaternary ammonium salt detergent and optionally an oxygen-containing detergent, and wherein the active metal compound is in the form of a colloidal dispersion, comprising an organic phase, particles of an iron compound in its amorphous form, and at least one amphiphilic agent. These compositions can be used in fuels to provide improved engine performance by, for example, reducing fuel injector fouling in the engine and/or by improving the regeneration of the engine's particulate exhaust trap.
