Adsorbent-based fuel system for on-board cetane on-demand and octane on-demand

摘要

How to operate a vehicle propulsion system, a vehicle fuel system, and an internal combustion engine. The separation unit that forms part of the fuel system adsorbs one or more so that the separation unit can selectively receive at least a portion of the onboard fuel and separate it into octane-enriched and cetane-enriched components. Includes wood-based chambers. Regeneration of adsorbents is carried out in relation to heat exchange with the existing system infrastructure. Using the controller, the on-board fuel is sent to one or more combustion chambers in the internal combustion engine without first passing through the separation unit, or instead the internal combustion engine is an octane-enriched or setan-enriched mixture. The specific operating conditions of the internal combustion engine can be determined so that it can be sent to the separation unit in situations where it may be necessary, so that the suction and the rest from the separation unit can later be mixed and used in the combustion chamber. , May be stored in separate tanks.
