Abstract
Hot exhaust gases are directly mixed with fuel before injection into the intake manifold of an internal combustion engine driven vehicle. The exhaust gases effect a complete vaporization of the fuel before combustion, and mixing of the gases and fuel is accomplished through a Venturi nozzle. The fuel and gas mixture also passes through a length of coiled tubing prior to entry into the intake manifold, with this tubing allowing for additional mixing and drying of the gas and fuel mixture.
Claims2
An apparatus for improving fuel vaporization prior to combustion in an internal combustion engine, said apparatus comprising:
- a. fuel supply means comprising a fuel tank, a fuel pump, and a metering means;
- b. mixing chamber means;
- c. exhaust gas delivery means in fluid communication with said mixing chamber means, said exhaust gas delivery means comprising a first conduit extending between an exhaust manifold and said mixing chamber means;
- d. fuel delivery means in fluid communication with said mixing chamber means, said fuel delivery means comprising a second conduit interconnected between said fuel supply means and said mixing chamber means;
- e. venturi nozzle means positioned in said mixing chamber means, said exhaust gas and said fuel being intermixed in said Venturi nozzle means;
- and,
- f. additional fuel vaporization means comprising a coiled conduit through which said intermixed exhaust gas and fuel passes.
