Concept: denitrification of waste gas in the concept vocabulary

Concept URI	http://www.eionet.europa.eu/gemet/concept/2072
Preferred label	denitrification of waste gas
Definition	Current methods for controlling NOx emissions in motor vehicles include retardation of spark timing, increasing the air/fuel ratio, injecting water into the cylinders, decreasing the compression ratio, and recirculating exhaust gas. For stationary sources, one abatement method is to use a lower NOx producing fuel or to modify the combustion process by injecting steam into the combustion chamber.
