Selective Catalytic Reduction
SCR

Diesel engine selective catalytic reduction (SCR) ceramic products of the main function is to reduce NOx in diesel exhaust emissions.
Urea aqueous solution is fully mixed by the mixer tail gas generated ammonia (NH₃) into the SCR catalytic converter. Nitrogen oxides NOx in the catalytic converter through internal reaction will generate harmless nitrogen dioxide (NO₂) and water (H₂O), reducing NOx emissions.
