Abstract
A fuel composition for use in internal-combustion engines has an alcohol component, a water component, and a cetane-enhancer component. An anhydrous emulsifier component may be either a glyceryl monooleate or ammonium oleate, and is present in an amount effective for the fuel, alcohol, water, and emulsifier components to form an emulsion. The fuel, alcohol, water, and emulsifier components are present in amounts effective to reduce emissions of nitrogen oxides by a threshold amount upon combustion of the fuel composition, relative to fuel alone.
Claims29
A fuel composition for use in internal-combustion engines, the fuel composition comprising:
- a fuel component;
- an alcohol component;
- a water component;
- an anhydrous emulsifier component chosen from the group consisting of glyceryl monooleate and ammonium oleate, being present in an amount effective for the fuel, alcohol, water, and emulsifier components to form an emulsion;
- and
- a cetane-enhancer component.
A fuel composition for use in internal-combustion engines, the fuel composition comprising:
- a hydrocarbon fuel component suitable for use in internal-combustion engines;
- an alcohol component;
- a water component;
- an anhydrous emulsifier component;
- and
- wherein the water and emulsifier are each provided in preselected amounts that are effective to achieve the desired NOX reduction, and wherein the water is provided in an amount according to the following formula:
- x % water to produce the desired NOX reduction in the range of 3-4x.
A fuel composition for use in internal-combustion engines, the fuel composition comprising:
- a hydrocarbon fuel component suitable for use in internal-combustion engines;
- a water component;
- an emulsifier component, the emulsifier being present in an amount effective for the hydrocarbon fuel, polar fluid, and emulsifier components to form an emulsion,
- wherein the emulsifier consists essentially of purified glyceryl monooleate;
- and
