Micropump applications diesel engine emissions control
To meet new NOx emissions standards, diesel engine manufacturers are turning to Selective Catalytic Reduction (SCR). SCR is an emissions control system that injects liquid urea into the catalytic converter in the exhaust stream of engines. The urea converts the NOx into harmless nitrogen and water. Gear pumps are used to deliver urea under pressure to a nozzle in the exhaust stream. Micropump Gear pumps provide the smooth flow and precise flow control required for this application.
SCR Technology is used in Heavy-duty trucks, automotive, off-road construction, mining, agriculture, power generation, locomotives, and ships for diesel engine emission control.
