Abstract: Gasoline blends and methods for producing gasoline blends containing high concentrations of a butanol isomer and having good cold start and warm-up driveability characteristics are disclosed.

Abstract: A process for determining the distillation characteristics of a liquid petroleum product that contains an azeotropic mixture of an oxygenated or nitrogen-containing component and at least one petroleum blending component.

Abstract: This invention relates to corrosion inhibitor additive combinations giving long acting performance in oxygenated gasoline blends comprising either low carbon number (<3) or high carbon number (greater than or equal to 4) alcohols or mixtures thereof and adapted for use in fuel delivery systems and internal combustion engines. The invention also is concerned with a process for conferring anti-corrosion properties to oxygenates in gasoline fuel mixtures wherein the oxygenate comprises biologically-derived butanol.

Abstract: A technique for engine control to account for fuel effects including providing an internal combustion engine and a controller to regulate operation thereof, the engine being operable to combust a fuel to produce an exhaust gas; establishing a plurality of fuel property inputs; establishing a plurality of engine performance inputs; generating engine control information as a function of the fuel property inputs and the engine performance inputs; and accessing the engine control information with the controller to regulate at least one engine operating parameter.

Abstract: Compositions of oxygenated gasolines are disclosed that have reduced vapor pressure compared to those containing a single oxygenate and no RVP reducing compound. Such compositions can be formed at a refinery or at a terminal. Methods of reducing vapor pressure of an oxygenated gasoline are disclosed and methods of reducing vapor pressure constraints upon a refinery in the production of oxygenated gasoline are disclosed. Fundamental properties of RVP reducing compounds are disclosed including IR spectrum analysis. Processes and methods for blending and distributing these fuels are also disclosed.

Abstract: A diesel fuel composition is disclosed, as well as a method for reducing NOx emissions from a diesel engine at minimum fuel consumption wherein the diesel engine operates in a low temperature combustion mode, comprising the step of adding to the diesel engine at least one diesel fuel or blending component for a diesel fuel having 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 an effective emissions reducing amount of a nitrogen-free cetane improver.

Abstract: A gasoline deposit control additive composition for use in a fuel comprising from about 70 to about 95 volume percent of hydrocarbons in the gasoline boiling range and from about 5 to about 30 volume percent of at least one alcohol, comprising the imine or tertiary amine product of the reaction between (a) at least one aldehyde or ketone or mixture thereof having the formula R16CHO, R16CH2CHO, R17(C=0)R18 or R17CH2(C=0)R18, wherein R16, R17, and R18 are the same or different and are each independently a straight or branched chain hydrocarbyl or aryl group that contains from 1 to 18 carbon atoms, and (b) a primary or secondary amine functionality.
