Abstract
A method for reducing NOx emissions during operation of an internal combustion engine in commerce which, when burning hydrocarbon fuel as a primary fuel, in the absence of any secondary fuel, has a characteristic stoichiometric ratio. The method includes: in the absence of electrolytic activity, providing and entraining a quenching species in a gaseous medium; and then interacting the quenching species with constituents present during oxidation of the primary fuel in a combustion chamber of the engine.

A method for reducing NOx emissions during operation of an internal combustion engine in commerce which, when burning liquid hydrocarbon fuel as a primary fuel, in the absence of any secondary fuel, has a characteristic stoichiometric ratio, the method comprising:
- providing a free nitrogen quenching species for interaction with constituents present during oxidation of the primary fuel in a combustion chamber of the engine while operating the engine at an air-to-fuel ratio greater than the characteristic stoichiometric ratio.
