In an embodiment, a fuel nozzle includes at least one port for receiving fuel, a sidewall forming ports for introducing fuel into a pre-combustion chamber, and a plurality of conduits formed between the first end and the sidewall. In one embodiment, a method includes creating a gaseous, homogenous premixture of fuel and oxidizer in a first pre-combustion vortex chamber, which includes introducing fuel at an axis of the oxidizer vortex both axially and radially through an injector having a plurality of ports through a sidewall arranged in a plurality of rows substantially parallel to one another. In an embodiment, an apparatus includes a pre-combustion fuel mixing device having a housing with a first pre-combustion vortex chamber having a first compartment, a second compartment, and a third compartment.
The present invention provides methods and apparatus for premixing fuel and oxidant for combustion. The methods and apparatus may include a two stage vortex, each stage accommodating different flow rate ranges. The vortex pulverizes fuel and optimally mixes the fuel with an oxidant prior to introduction into a combustion chamber. The premixing results in more complete combustion and, consequently, fuel efficiency may be increased and pollution may be decreased. The present invention also enables introduction of fuel and oxidant to an engine without creating any shockwaves in engine cylinders, which may otherwise occur with current fuel injection systems.
