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.

Oxygenated butanol gasoline composition having good driveability performance

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.

Process for determining the distillation characteristics of a liquid petroleum product containing an azeotropic mixture

This invention relates to corrosion inhibitor additive combinations giving long acting performance in oxygenated gasoline blends comprising either low carbon number (&#x3c;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.

Corrosion inhibitor compositions for oxygenated gasolines

The invention relates to butanol compositions for fuel blending and fuel blends comprising such compositions. The compositions and fuel blends of the invention have desirable performance characteristics and can serve as alternatives to ethanol-containing fuel blends. The invention also relates to methods for producing such butanol compositions and fuel blends.

Butanol compositions for fuel blending and methods for the production thereof

A gasoline blend and a method for producing a gasoline blend containing low concentrations of a butanol isomer and having good cold start and warm-up driveability characteristics are disclosed.

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.

Engine control techniques to account for fuel effects

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&#xb0; C. to 280&#xb0; 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.

Composition and method for reducing NOx emissions from diesel engines at minimum fuel consumption

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 RCHO, RCHCHO, R(C=0) Ror RCH(C=0) R, wherein R, R, and Rare 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.

Gasoline deposit control additive composition

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.

Transportation fuels

An unleaded reduced emissions gasoline having at least one of an octane less than about 86.7, a sulfur content less than about 40 ppmw sulfur and containing an oxygenate, and having reduced emissions by comparison to a minimum 87 octane gasoline. A method for reducing emissions from an automotive internal combustion engine is provided for a single vehicle and for a fleet. A method for reducing emissions by use of a distribution network is disclosed and a system for reducing emissions by a combination of a refinery and the vehicles is disclosed.
