Nitrogen Enriched Combustion of a Natural Gas Internal Combustion Engine to Reduce NOx Emissions (IN-03-120)

Argonne licensing opportunity

A method and system for reducing nitrous oxide emissions from an internal combustion engine. An input gas stream of natural gas includes a nitrogen gas enrichment which reduces nitrous oxide emissions. In addition ignition timing for gas combustion is advanced to improve FCE while maintaining lower nitrous oxide emissions.
