ABSTRACT:
In an internal combustion engine, fuel is delivered from a fuel source through a pressurized fuel line into a first flow conditioner. A return pressure regulator is connected to the pressurized fuel line and bleeds excess fuel pressure back into the fuel source. The first flow conditioner disrupts the flow of the fuel in the fuel line and disperses the fuel molecules. From the first flow conditioner, the fuel travels into a fuel expander which is connected to a source of heat. The fuel is heated in the fuel expander thereby exciting the fuel molecules. From the fuel expander the fuel is directed through a second flow conditioner to further agitate the fuel molecules. A metered amount of fuel is then passed into the internal combustion engine for combustion by the engine. A fuel pressure regulator is connected to the internal combustion engine and maintains a constant fuel pressure in the fuel delivery system. Surplus fuel unused by the engine is passed through the fuel pressure regulator and into a fuel recirculation line. The fuel recirculation line is connected to the pressurized fuel line at a position close to the first flow conditioner to further elevate the temperature of the fuel delivered to the internal combustion engine.
