Regeneration of solvent based adsorbents for on-board Octane on demand and cetane on demand

摘要

A vehicle propulsion system, a vehicle fuel system, and a method of generating fuel for an internal combustion engine.An isolation unit for forming a portion of the fuel system includes one or more adsorbent based reaction chambers to selectively receive at least a portion of the loaded fuel and separate it into the octane enrichment and the cetane enrichment.The regeneration of the adsorbent is performed by the interaction with the solvent, and the solvent can be recycled by subsequent separation.The on-board fuel may first be sent to one or more combustion chambers within the internal combustion engine without passing through the separation unit, or alternatively, may be sent to the separation unit in a situation where the internal combustion engine may require a mixture of octane enrichment or cetane enrichment A controller may be used to determine a particular operating condition of the internal combustion engine.
