Abstract
An additive for gasoline comprises a polyoxyethylene sorbitol polyoleate. It may be provided to the gasoline, which is typically gasohol, as a dispersion in a gasoline - miscible solvent to typically provide an additive concentration in the gasoline of 100 to 1000 p.p.m. The additive acts to prevent formation of a separate alcohol-water phase in the gasoline by making the phase more readily dispersable in the gasoline.
Claims10
A method for improving the quality and performance of an internal combustion engine, which method comprises the steps of:
- (a) introducing gasoline into the fuel tank of the internal combustion engine;
- and
- (b) adding to the gasoline, in an amount effective to improve the performance of an internal combustion engine, a stable dispersion of 3 to 20 volume percent of a compound consisting essentially of polyoxyethylene sorbitol polyoleate in a gasoline-miscible oxygenated organic solvent;
- and
- (c) operating the engine.
A method for improving the quality and performance of an internal combustion engine, which method comprises the steps of:
- (a) introducing gasoline into the fuel tank of the internal combustion engine;
- and
- (b) adding to the gasoline, in an amount effective to improve the performance of an internal combustion engine, a stable dispersion of an effective amount of a compound consisting essentially of polyoxyethylene sorbitol polyoleate in a gasoline-miscible oxygenated organic solvent to cause any water-alcohol phase to remain intimately dispersed throughout the gasoline;
- and
- (c) operating the engine.
