L'AUS 32 (en anglais : aqueous urea solution) est une solution aqueuse d'urée composée de 32,5 % d'urée et de 67,5 % d'eau déminéralisé est utilisée dans le processus de réduction catalytique sélective (SCR). C'est un fluide d'échappement diesel (FED) (en anglais Diesel exhaust fluid, DEF), aussi appelé AdBlue (marque déposée). L' AUS 32 est standardisée selon la norme ISO ...
The SCR catalyst reduces NOx (NO/NO2) by injecting and diffusing AdBlue (an aqueous dilution of Urea) into the exhaust stream upfront of the catalysts then converting the AdBlue (Urea) into gaseous ammonia (NH3) within the exhaust.

Feb 17, 2019· AdBlue is the German brand name for a clear, non-toxic—though slightly corrosive to some metals—aqueous urea solution used to treat exhaust on modern clean diesel engines. The generic name for a chemically equivalent solution used in the non-European market (predominantly North America) is Diesel Emissions Fluid (DEF).
A:AdBlue is a diesel exhaust fluid used in vehicles with Selective Catalytic Reduction (SCR) technology to reduce harmful gases being released into the is a % solution of high_purity,synthetically manufactured urea in de-mineralized is a safe-to-used fluid.
Its principle is based on NH3, urea [CO (NH2) 2], etc. Before the boiler is atomized or injected into the boiler, it is atomized by the heat in the furnace. Sprayed into the furnace temperature range of 800 ℃ ~ 1100 ℃, the reducing agent quickly thermally decomposed into NH3 and other by-products, and then NHCR and NOx in the flue gas ...
AdBlue® is injected into the exhaust gas flow and morphes into ammonia (NH3). During a chemical reaction this ammonia reduces the harmful NOx parts within the exhaust stream. The NOx parts are unchained and rebonded into nitrogen and water vapor. By side effect AdBlue® also reduces the fuel consumption up to 5% and fine dust emissions.
Our device for countries that havent euro 4/5/6 ecologic rules. Adblue remove emulator, stoped the DEF liquid flowing in scr system. Adblue remove emulator sell for countries that havent adblue liquid and use for during the remove faults in adblue systems. This is a personal decision to buy this device.
AdBlue ® ist eine hochreine, wässrige Harnstofflösung, die als Betriebsstoff in Dieselfahrzeugen eingesetzt wird. AdBlue ® ermöglicht die Reduzierung von Stickoxid-Emissionen um bis zu 90 Prozent. Die farblose AdBlue®-Flüssigkeit gefriert bei -11,5 °C. Bei +80 °C zerfällt AdBlu ® in gasförmiges Ammoniak (NH3) und Kohlendioxid (CO2). Bereits bei +30 °C sind erste Ammoniak-Spuren ...

Aug 12, 2018· When AdBlue is injected into the hot exhaust steam, it is reduced to water and urea. At a temperature of about 400 degrees Fahrenheit (170 Celsius), the urea reforms into ammonia (NH3) which then reacts with NOx gasses in the converter to produce benign nitrogen gas and water vapor.
Components of NH3 Slip Detection Logic 29-Sept-2010 2010 DEER Conference 4 Frequency Analysis • By observing the frequency content of the upstream and downstream NOx signals, there is potential to detect presence of NH3 slip in the downstream signal. Statistical Analysis • By observing how well the downstream NOxsignal moves relative to the
AdBlue® is injected into the exhaust pipe, located before the SCR catalyst and after the engine. When heated inside the exhaust pipe, AdBlue® decomposes into ammonia (NH3) and carbon dioxide (CO2). When the NOx react with the ammonia inside the catalyst, the harmful NOx molecules are transformed into harmless nitrogen (N2) and water (H2O). 5.

Sep 09, 2019· Adblue is injected directly into the exhaust system to assist in the Nox reduction process. it basically aids the system to clear soot deposits out when it turns to ammonia in order for the emissions system to be fully functioning. Some vehicle manufacturers don't need it but sadly VW do.

Mar 08, 2019· AdBlue Fluid injection unit; AdBlue tank; AdBlue injection control unit. The AdBlue is injected from the AdBlue tank into the exhaust pipe, which is in front of the SCR catalyst, but downstream of the engine. As it is heated in the exhaust, the AdBlue changes into ammonia (NH3) and carbon dioxide (CO2).
AdBlue® Fluid injection unit; AdBlue® tank; AdBlue® injection control unit. AdBlue® is injected from the vehicle’s dedicated AdBlue storage tank into the exhaust pipe, which is just before the SCR catalyst, but downstream of the engine. As it is heated in the exhaust, AdBlue® releases ammonia (NH3) and carbon dioxide (CO2).
