Multi-Fuel Plasma Injector

The inventive subject matter provides apparatus, systems and methods for treating and delivering a fuel to a combustion chamber of an engine in order to improve efficiency of the engine. In one aspect of the invention, a fuel injector that cooperates with an internal combustion engine to combust a first fuel to produce power is presented. The fuel injector includes a fuel inlet, a pre-conditioning vortex chamber, and an excitation chamber. The fuel injector includes a vortex chamber that conforms a pulsed amount of the first fuel to produce a vortex that includes a coherent dynamic pressure wave. The fuel injector also includes an excitation mechanism that at least partially ignites the fuel.
