Abstract (en)

Formation of deposits in fuel injectors of diesel fueled engines is inhibited by addition of an alkenyl succinic acid to the diesel fuel. The invention provides a composition, for inhibiting the formation of deposits in diesel fuel injection systems, comprising an alkenyl succinic acid or mixtures thereof, a composition comprising a diesel fuel and, in an amount effective to inhibit formation of deposits in injection systems, an alkenyl succinic acid or mixtures thereof and a method of inhibiting the formation of deposits in fuel injectors of diesel fueled engines which comprises adding to said diesel fuel a composition comprising an alkenyl succinic acid or mixtures thereof in an amount effective to inhibit the formation of deposits. The acid may be tetrapropenyl succinic acid and the compositions may comprise a hydrocarbon solvent such as xylene.
