Selective catalytic reduction (SCR) for diesel engines
Selective catalytic reduction (SCR) is an advanced active emissions control technology system that injects a liquid-reductant agent (urea) through a special catalyst into the exhaust stream of a diesel engine. SCR catalyst can removes nitrogen oxides from diesel vehicles, in the SCR process, the reducing agent reacts with NOX to convert the pollutants into nitrogen, water and tiny amounts of carbon dioxide, which is then expelled through the vehicle tailpipe. Applications include medium and heavy-duty diesel trucks, all on round and non-road vehicle and various construction machinery vehicles.
