AdBlue® SCR* technology: Reduced NOx emissions
© Celanese Fuel Systems Solutions 23
► AdBlue® = aqueous urea solution used in Selective Catalytic Reduction (SCR) Systems
► Reduces nitrogen oxide concentration in the exhaust emissions from diesel engines.
► Use of SCR technology in vehicles eliminates the need to switch to the so called ‘rich-burn mode’ to regenerate the storage
► Diesel engine can be further improved for reduced fuel consumption.
* Selective Catalytic reduction Adblue is a registered trademark of VDA
Fortron® PPS Celstran® LFT PP and LFT PA Hostaform® POM
For direct contact with AdBlue® e.g. pumps, valves, sensors
AdBlue Contamination below all limits tested according DBL 5419
