ANTI-KNOCK INTERNAL COMBUSTION ENGINE FUEL

摘要

COMPOSITION AND METHOD An improved fuel composition comprising a major amount of hydrocarbons boiling in the gasoline boiling range; a minor amount of at least one hydrocarbon-soluble compound of a metal selected from the group consisting of manganese, technetium, rhenium and mixtures thereof capable of improving the octane number rating of the composition; a minor amount of at least one aliphatic alcohol containing from 1 to about 8 carbon atoms per molecule; and a minor amount of water wherein the compound and the combination of alcohol and water are present in mutually activating amounts to improve the octane number rating of the fuel composition. An improved method for fueling an internal combustion engine using the composition described above is also disclosed.
