摘要:
A method of operating a vehicle system including an internal combustion engine is disclosed, the method comprises separating a second fuel from a first fuel, the second fuel having a greater concentration of at least one component than the first fuel; combusting at least the first fuel at least during a first engine load; and combusting at least the second fuel at least during a second engine load higher than the first engine load.
摘要:
Systems and methods are provided for extracting components of a mixed fuel into at least one substantially non-polar component and at least one polar fuel component. In one example approach, a volume of a mixed fuel is added to an extractor and a polar solvent is used to extract components of the mixed fuel. The extracted components may be selectively provided to an engine in a ratio based upon engine operating conditions.

In an apparatus comprising a fuel tank, an internal combustion engine, and a separator positioned fluidically between the fuel tank and the internal combustion engine, a method of operating the apparatus is disclosed, wherein the method comprises inputting a mixed fuel containing a hydrocarbon component and an oxygenated component into the separator, separating the fuel in the separator into a hydrocarbon-enriched fuel fraction and an oxygenated fuel component-enriched fuel fraction, and controlling an amount of the hydrocarbon-enriched fuel fraction and an amount of the oxygenated fuel component-enriched fuel fraction provided to the engine based upon an engine operating condition.
摘要:
An apparatus comprising an internal combustion engine, a fuel tank, a fuel separator disposed fluidically between the fuel tank and the engine, wherein the fuel separator comprises first and second passageways separated at least partially by a selective barrier that selectively transports a first fuel in a fuel mixture at a higher rate than a second fuel in the fuel mixture, and wherein the first passageway is configured to receive an input of fuel from the fuel tank, and an extraction fluid source in fluid communication with the second passageway of the fuel separator.

In an apparatus having an internal combustion engine, a method of operating the engine is disclosed, comprising providing a mixed fuel from a fuel tank to a separator, separating at least a portion of the hydrocarbon fuel component from the mixed fuel by transporting a hydrocarbon fuel component through a material in the separator that selectively transports the hydrocarbon fuel component, thereby forming a first oxygenated fuel component-enriched fuel fraction and a second hydrocarbon-enriched fuel fraction, and providing fuel from the first fuel fraction and fuel from the second fuel fraction to the engine in a ratio based on an engine operating condition.
