Abstract

Abstract An additive composition for use in fuel to be combusted in an internal combustion engine, the composition comprising, in admixture form: (a) between about 0.05 and 25% relative weight parts of an organic peroxide, and (b) between about 0.1 and 25% relative weight parts of detergent selected from the component group that consists of: (i) fatty amines (ii) ethoxylated and propoxylated derivatives of fatty amines (iii) fatty diamines (iv) fatty imidazolines (v) polymeric amines and derivatives thereof (vi) combination of one or more of said (i) through (v) components with carboxylic acid or acids having from three to forty carbon atoms.
