DIESEL FUEL CONTAINING ESTER TO REDUCE EMISSIONS

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 thr ee or more primary alcohol groups, (ii) a C2-C15 saturated, aliphatic branc...

More Information
Summary: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 thr ee or more primary alcohol groups, (ii) a C2-C15 saturated, aliphatic branched chain monohydric alcohol and (iii) a saturated, aliphatic C4-C10 dicarboxyli c acid, or (b) a saturated aliphatic polyhydric alcohol having three or more primary alcohol grouped 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 molecula r weight >=200 and an oxygen content >=13 % by weight of said ester addi tive mixture. The additive significantly reduces particulate emissions from the exhausts of diesel powered engines.
