MTU Schematic SCR System
Schematic of the SCR system
Selective catalytic reduction describes a way to minimize the amount of nitrogen oxide contained in the exhaust gases. A urea-water solution is injected into the exhaust gas flow upstream of the SCR catalytic converter, thus producing nitrogen and water during the selective catalytic reduction process.

N2: Nitrogen
NH3 Ammonia
NO Nitrogen Monoxide
