Abstract | This invention is a fuel composition comprising a major amount of base fuel and at least 3% w/w of an ester additive mixture derivable by reacting together either(a) (i) a saturated, aliphatic polyhydric alcohol having three or more primary alcohol groups, (ii) a C2-C15 saturated, aliphatic branched chain monohydric alcohol and (iii) a saturated, aliphatic C4-C10 dicarboxylic acid, or(b) a saturated aliphatic polyhydric alcohol having three or more primary alcohol groups with a C6-C15 saturated, aliphatic straight chain or branched chain monocarboxylic acid, or(c) a C2-C15 branched chain saturated aliphatic alcohol with a saturated, aliphatic dicarboxylic acid having 6-10 carbon atoms.The ester additive has a boiling point >=150° C., a molecular weight >=200 and an oxygen content >=13% by weight of said ester additive mixture. The additive significantly reduces particulate emissions from the exhausts of diesel powered engines. |
