SCR Trouble Cause

Filter Clogging

-pH9 Alkalescent AUS + Aldehyde’s Carboxylic acid = Ammonium Salt
Insoluble Matter
-AUS Metallic Ions + Atmospheric CO2 = Metallic Salt

Injection Clogging

-Biuret & Triuret + 250 ℃ Exhaust gas = Cyanuric acid Salt
-AUS NH3 + Aldehyde’s Carboxylic acid = Ammonium Salt

Exhaust Catalyst Blockage

-Damage of AUS Injection blockage due to NOx
-Biuret & Triuret + 250 ℃ Exhaust gas = Cyanuric acid Salt
– Aldehyde’s Carboxylic acid + NH3 = Ammonium Salt
-AUS Metallic Ions + CO2 = Metallic Salt

Trouble Result

-NOx emit out to atmosphere
-Engine Power & Fuel Efficiency down.
-SCR Function down.
-Parts Change Cost USD 4,200 (7 break down out of 10)
-Engine Damage.
