Internal combustion engine equipped with fuel reforming system

A fuel reforming system for an internal combustion engine, comprising:

• fuel reforming means for converting a hydrocarbon gas mixture containing a hydrocarbon gas, water vapor and air to a reformed gas mixture containing a reformed gas and an unreformed hydrocarbon gas;
• cooling means for cooling said reformed gas mixture and condensing said unreformed hydrocarbon gas into a high octane liquid fuel;
• and
• control means for controlling selective supply of said reformed gas and said high octane liquid fuel to the engine in accordance with an engine operating condition.

A process for converting a hydrocarbon fuel to a reformed gas and a high octane liquid fuel for use in an internal combustion engine, comprising:

• mixing said hydrocarbon fuel with water and gasifying a mixture of said hydrocarbon fuel and said water to obtain a mixture of a hydrocarbon gas and water vapor;
• mixing said mixture of said hydrocarbon gas and said water vapor with air to obtain a hydrocarbon gas mixture;
• converting said hydrocarbon gas mixture to a reformed gas mixture containing a reformed gas and an unreformed hydrocarbon gas through reformation by a water vapor reformation reaction and a partial oxidation reaction;
• and
• cooling said reformed gas mixture in such a manner that said unreformed hydrocarbon gas is condensed into said high octane liquid fuel and separated from said reformed gas.
