Abstract
An apparatus, system, and method are disclosed for minimizing NOin exhaust gasses. The apparatus includes an ionization module configured to at least partially ionize an exhaust gas of an engine. A characterization module is configured to identify NOions present in the ionized exhaust gas, and an engine control module is configured to communicate with the characterization module and modify engine parameters in response to identified NOlevels. The system includes an internal combustion engine having an intake manifold configured to deliver an air-fuel mixture to at least one combustion chamber, an exhaust manifold configured to receive exhaust gasses from the combustion chamber, and the apparatus. The method includes controlling an ionization module configured to at least partially ionize an exhaust gas of an engine, identifying NOions present in the ionized exhaust gas, and modifying one or more selected engine parameters in response to identified NOlevels.
