Abstract:
1. An apparatus for reducing NOx exhausted from combustion engines comprising: a first end, a second end, and a middle portion, wherein the first end comprises a connector capable of being adapted to an intake of a combustion engine; the second end comprises an interface exposed to an air source; the middle portion communicating air from the second end to the first end and comprising an oxygen enhancer, such that the air communicated from the air source to the combustion chamber of the engine has enhanced oxygen content; a controller coupled with the middle portion for regulating the air flow with enhanced oxygen content and a quantity of fuel for maintaining a designed output power of the engine based upon combusting the fuel in the engine with air having ambient air concentration of oxygen so that the output power from the engine upon combustion of the fuel with oxygen enriched air is the same power as would be produced by combusting the fuel in air with ambient oxygen concentration; and a fuel supply to supply the quantity of fuel to produce the designed engine power output according to the controller.
