AI Technical Summary

Benefits of technology

This patent describes a gasoline additive that increases the octane rating of gasoline. The additive contains an oxygenate and an optical brightener. The patent also describes a method for making the additive and a gasoline blend that contains the additive. The technical effect of this patent is to improve the quality and performance of gasoline as an engine fuel.

Problems solved by technology

When used in high compression internal combustion engines, gasoline has the tendency to “knock.” Knocking occurs when combustion of the air / fuel mixture in the cylinder does not start off correctly in response to ignition because one or more pockets of air / fuel mixture pre-ignite outside the envelope of the normal combustion front.
However, the production and storage of the large quantities of these materials at oil refineries can be costly.
In addition, limitations on the use of high concentrations of additives by regulatory mandate increase the difficulty and expense of refining operations that produce high-octane fuels.

Abstract

A gasoline additive composition includes an oxygenate gasoline additive; and an optical brightener. The gasoline additive composition can be used in a gasoline blend.

Description

BACKGROUND[0001]This disclosure is directed to a process for improving octane boosters for gasoline, the improved boosters, and gasolines containing the boosters.[0002]Commercial gasoline, which is fuel for internal combustion engines, is a refined petroleum product that is typically a mixture of hydrocarbons (base gasoline), additives, and blending agents. Additives and blending agents are added to the base gasoline to enhance the performance and the stability of gasoline, and can include anti-knock agents, anti-oxidants, metal deactivators, lead scavengers, anti-rust agents, anti-icing agents, upper-cylinder lubricants, detergents, and dyes.[0003]When used in high compression internal combustion engines, gasoline has the tendency to “knock.” Knocking occurs when combustion of the air / fuel mixture in the cylinder does not start off correctly in response to ignition because one or more pockets of air / fuel mixture pre-ignite outside the envelope of the normal combustion front.
