Patent ID: 7240662

Claim:
A method to improve the kinetics and fuel efficiency of the combustion process in a fuel injected internal combustion engine, resulting in the reduction of fuel consumption and harmful emissions while maintaining performance of the engine, comprising: a) providing a constant volume of liquid hydrocarbon fuel from the fuel tank to the fuel rail and injectors of said fuel injected engine; b) maintaining said volume of liquid fuel for delivery to said injectors under an operating pressure between 25 and 60 psi, or as specified for each engine; c) directing said pressurised liquid fuel through a primary fuel supply conduit defining a heat exchange assembly that extends through a heating zone within the engine cooling system, having a fuel inlet and outlet; d) providing a fuel pressure relief valve located ahead of said heat exchange assembly and ahead of the fuel rail, rather than beyond the fuel rail, operational to return excess fuel unheated to the fuel tank; e) increasing the flow speed and volatility of said constant volume of pressurised liquid fuel by turbulating and heating the fuel in said heat exchange assembly to an optimal operating temperature in accordance with the following parameters: for fuel supplied at a pressure condition of 25 psi or higher, heat the fuel to an operating temperature range of 85 to 130 degrees F: for fuel supplied at a pressure condition of 30 psi or higher, heat the fuel to an operating temperature range of 85 to 160 degrees F: for fuel supplied at a pressure condition of 35 psi or higher, heat the fuel to an operating temperature range of 85 to 190 degrees F: for fuel supplied at a pressure condition of 40 psi or higher, heat the fuel to an operating temperature range of 85 to 220 degrees F: f) maintaining the temperature of the pressurised liquid turbulated fuel at its most optimal operating level without causing vaporisation of the heated liquid fuel prior to injection into the engine.
