  • Publication number: 20110265773
    Abstract: A diesel fuel composition is disclosed, as well as a method for reducing NOx and smoke emissions from a diesel engine at minimum fuel consumption which comprises adding to the diesel engine at least one diesel fuel or blending component for a diesel fuel which has a combination of a low T50 in the range of from 190° C. to 280° C., a high cetane number in the range of from 31 to 60, and optionally a high distillation curve slope in the range of from 58° C. to 140° C., which combination is effective to afford a combination of the lowest NOx and smoke emissions at the lowest fuel consumption at independent engine control values for the diesel engine that are optimum to afford production of a combination of the lowest NOx and smoke emissions at the lowest fuel consumption, whereby the NOx and smoke emissions from the diesel engine are reduced by at least 10% and 15%, respectively.

    Abstract: The present invention relates to Compositions of fuels for transportation are disclosed, particularly organic compositions which are liquid at ambient conditions. More specifically, it relates to transportation fuels comprising suitable organic distillates, as a predominant component, and limited, but essential, amounts of a component comprising oxygen-containing organic materials, which materials are typically derived from natural petroleum. Beneficially, the oxygen content of these transportation fuels is at least 0.02 percent by weight. Preferably the oxygen content these transportation fuels is in a range from about 0.2 percent to about 10 percent by weight.

  • Publication number: 20030196372
    Abstract: A fuel additive package is disclosed that prevents degradation of hydrocarbon fuels upon storage and permits extended use of such motor fuels without intake-valve deposit formation in vehicle motors. The additive contains an antioxidant, metal deactivator, corrosion inhibitor, and detergent. The corrosion inhibitor, preferably a carboxylic acid containing a carbon number equal to or less than 18 and the detergent component, preferably a polyisobutylene diamine are selected to avoid antagonistic effects with the antioxidant and metal deactivator components while the antioxidant and metal deactivator components are used in markedly reduced amounts to avoid antagonistic effects resulting in increased intake-valve deposits.
