The oxygenate significantly reduces particulate emissions from the exhausts of diesel powered engines.Type: GrantFiled: December 7, 2000Date of Patent: October 1, 2002Assignee: ExxonMobil Research and Engineering CompanyInventors: Lisa I-Ching Yeh, Richard Henry Schlosberg, Richard C.

Patent number: 6447558Abstract: 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.Type: GrantFiled: December 7, 2000Date of Patent: September 10, 2002Assignee: ExxonMobil Research and Engineering CompanyInventors: Lisa I-Ching Yeh, Richard Henry Schlosberg, Richard C.

Patent number: 6447557Abstract: 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.Type: GrantFiled: December 7, 2000Date of Patent: September 10, 2002Assignee: ExxonMobil Research and Engineering CompanyInventors: Lisa I-Ching Yeh, Richard Henry Schlosberg, Richard C.

Publication number: 20020026744Abstract: The invention relates to a motor fuel suitable for diesel, gas-turbine and jet engines and standard engines, comprising a mixture of organic compounds having oxygen-containing functional groups, and optionally a hydrocarbon fraction. The fuel is typically a stable homogeneous liquid at atmospheric pressure and normal ambient temperature and achieves a reduction of harmful pollutants in the exhaust emissions of the engines. A total of at least four different oxygen-containing functional groups are present in at least two different oxygen-containing organic compounds. The total concentration of organic compounds containing bound oxygen in the fuel composition generally varies from 5% and to 100% of the total volume of the fuel composition, and the concentration of the hydrocarbon compounds varies, correspondingly, from 95% to 0% of the total volume of the fuel composition.Type: ApplicationFiled: May 4, 2001Publication date: March 7, 2002Inventors: Angelica Golubkov, Igor Golubkov
