Abstract:
A fuel composition comprising:(A) a major amount of a base distillate fuel having a. no more than 50 ppm by weight of sulphur, b. no more than 10% by weight of olefins, c. no more than 10% by weight of an ester d. a density below 850 kg/m3 and a T95 of no more than 345Â° C.; and (B) at least 1% by weight based on the total fuel composition of an additive for reducing particulate emissions consisting essentially of an oxygenate selected from the group consisting of saturated, aliphatic monohydric primary, secondary, tertiary alcohol and mixtures thereof having an average of from 4-20 carbon atoms, one or more mono- or poly-ketone or keto-monohydric aliphatic alcohol having on an average 5 to 25 carbons, and mixtures of the aforesaid alcohol(s) and ketone(s) and having no other oxygen atom in its structure, the amount of the oxygenate in the composition being sufficient to provide the fuel with at least 2% by weight of oxygen.
