Abstract
A vehicular propulsion system, a vehicular fuel system and a method of producing fuel for an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based reaction chambers to selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced components. Regeneration of an adsorbate takes place through interaction with a solvent, while subsequent separation allows the solvent to be reused. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.
