    Abstract: This invention is a fuel composition for use in internal combustion engines comprising a major amount of a base fuel which contains no more than 10% by weight of olefins and no more than 10% by weight of esters, and greater than 5% by weight based on the total composition of an oxygenate selected from the group consisting of a saturated, aliphatic monohydric alcohol having on an average from 8 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons, and mixtures of the alcohol(s) and ketone(s). The amount of the oxygenate in the fuel composition is sufficient to provide the fuel with at least 0.5% by weight of oxygen. The oxygenate significantly reduces particulate emissions from the exhausts of diesel powered engines.

    Abstract: This invention relates to a diesel fuel composition comprising a major amount of a base fuel and a relatively minor amount of at least one chemical component other than that generated in a refinery process stream which component is miscible with the base fuel in such proportions that the T30 temperature of the resultant composition is in the range from 205-240° C. The control of the T30 temperature within the specified range by blending with the minor component results in a significant reduction in particulate emissions.

    Abstract: This invention relates to an ultra-low sulphur fuel composition comprising (A) a major amount of a base fuel having (a) no more than 50 ppm by weight of sulphur, (b) no more than 10% by weight of olefins and (c) no more than 10% by weight of an ester and (B) at least 1% by weight based on the total fuel composition of an oxygenate selected from its group consisting of a saturated, aliphatic monohydric alcohol having 4 to 20 carbon atoms, ketone having on an average 5 to 25 carbons and mixtures of the alcohol(s) and ketone(s) and having no other oxygen atom in its structure. These specific oxygenates further reduce particulate emissions from the exhausts of engines powered by ultra-low sulphur diesel fuels which fuels are already known to generate low particulate emissions. These oxygenates are capable of an impressive performance with respect to particulate emissions over a broad range of vehicles and driving cycles when compared with the performance of oxygenates used hitherto.

    Abstract: This invention is a method of reducing particulate matter emission from internal combustion engines which use a diesel fuel composition comprising a major amount of a diesel fuel having a base fuel which contains no more than 10% by weight of olefins and no more than 10% by weight of esters, by admixing said fuel with greater than 5% by weight based on the total composition of a saturated, aliphatic monohydric alcohol having on an average from 4 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons and mixture of said alcohol(s) and ketone(s). The amount of the oxygenate in the fuel composition is sufficient to provide the fuel with at least 0.5% by weight of oxygen. The oxygenate significantly reduce particulate emissions from the exhausts of diesel powered engines.
