Abstract: A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may 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 a heat exchange relation with existing system infrastructure. 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, where adsorbed and remainder portions taken from the separation unit may be stored in separate tanks for later mixing and use within the combustion chamber.

A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate.

Abstract: The present invention provides a novel apparatus and method for the gasification of liquid petroleum fuel (gasoline), that has been atomized and emulsified with atmospheric air, by implementing a multi-Stage Heat Exchanger System. The first stage employs a spigot mounted carburetor or fuel injection unit, positioned in a straight line laminar flow path, flowing into an exhaust gas heated “Shell and Tube” style heat exchanger unit. In the second stage, the already heated gasoline vapor mixture then flows into an attached compressor housing inlet of a “Draw through Turbine Heat Exchanger Compressor” component, which through an impeller means, further heats and compresses the vaporous air and gasoline mixture. The third stage, utilizes an “Exhaust Gas Heat Exchanger Coil” or alternative “Heat Exchanger Sphere”, which is fitted internally, into conduction heated metal open plenum style intake manifold. The heated gaseous air and fuel vapor mixture then flows into the engines valve controlled cylinder head intake ports, and into the engines combustion chambers. The heated air and fuel mixture is maintained in a dry homogenous gaseous form. The entire flow path of atmospheric air and gasoline vapor mixture is consistently kept heated in a uniform manor after leaving the carburetor or fuel injection unit, until it enters the engines combustion chamber. This eliminates condensation of the gaseous gasoline vapor back into a liquid form. The intent of this invention is to greatly increase the efficiency, fuel mileage and power output, and also to significantly reduce automotive exhaust emissions, from an internal combustion engine. The present invention provides a novel apparatus and method for the gasification of liquid petroleum fuel (gasoline), that has been atomized and emulsified with atmospheric air, by implementing a multi-Stage Heat Exchanger System.
