    摘要: A method for operating an internal combustion engine includes combusting a fuel and air mixture within a combustion chamber of an internal combustion engine, thereby forming an exhaust gas, passing the exhaust gas out of the combustion chamber, performing a startup procedure, the startup procedure including passing the exhaust gas from the combustion chamber to a storage unit, capturing criteria pollutants of the exhaust gas with the storage unit, passing the exhaust gas from the storage unit to an aftertreatment system, heating the aftertreatment system to an activation temperature with the exhaust gas from the storage unit, and subsequent to heating the aftertreatment system to the activation temperature, performing a secondary procedure, the secondary procedure including passing the exhaust gas from the combustion chamber to the aftertreatment system thereby forming a treated exhaust gas, and passing the treated exhaust gas to the storage unit.

    摘要: The present application is directed to systems and methods for on-board fuel separation. The system includes: a source fuel tank for liquid fuel; a pump; and a membrane module. The membrane module includes a hydrophilic membrane, a retentate channel, and a permeate channel. The retentate and permeate channels are on opposing sides of the membrane. The membrane module receives fuel from the source fuel tank and separates the liquid fuel into a high octane fraction that collects in the retentate channel and a low octane fraction that diffuses through the membrane to the permeate channel. The system further includes a low octane fuel tank for receiving at least a portion of the low octane fraction, a high octane fuel tank for receiving at least a portion of the high octane fraction, and an engine configured to selectively receive at least a portion of the low and high octane fractions.

    摘要: Systems and methods for capturing carbon dioxide (CO2) in exhaust gases of a vehicle include delivering the exhaust gas to a cooled section of a rotary contactor, the rotary contactor including openings that extend from a first side of the rotary contactor to a second side of the rotary contactor. The CO2 of the exhaust gas is adsorbed with a sorbent of the cooled section of the rotary contactor, where the non-CO2 components of the exhaust gas pass through the openings. The cooled section of the rotary contactor is heated with a hot fluid of the vehicle to release the adsorbed CO2 and convert the cooled section of the rotary contactor to a heated section of the rotary contactor. The heated section of the rotary contactor is cooled to convert the heated section of the rotary contactor back to the cooled section of the rotary contactor.

    摘要: Systems and methods for treating automotive vehicle emissions on board an automotive vehicle include the use of waste heat recovery, electrochemical water splitting, phototcatalytic water splitting, and selective catalytic reduction. Waste heat recovery is used to power electrochemical water splitting, or photocatalytic water splitting. Photons collected from a solar panel are used in photocatalytic water splitting, or in photo-assisted selective catalytic reduction. Hydrogen gas generated by water splitting is used in conjunction with catalytic reduction units to catalytically reduce NOx in an engine exhaust gas.
