ADBLUE / SCR REMOVAL

ADBLUE (Diesel Exhaust Fluid)

AdBlue is a fluid used to reduce emissions in diesel engines. Also commonly known as "Diesel Exhaust Fluid" (DEF). AdBlue is used in SCR (Selective Catalytic Reduction) systems to reduce nitrogen oxide (NOx) emissions in modern diesel engines.

FUNCTION OF ADBLUE (Diesel Exhaust Fluid)

1. Function:

AdBlue is a solution of urea and pure water injected into the exhaust system of diesel engines, converting harmful NOx emissions in exhaust gases into harmless nitrogen and water vapor.

2. Working Principle:

SCR System: AdBlue solution is injected into the exhaust system while the exhaust gases of the diesel engine pass through the SCR catalyst.
Chemical Reaction: AdBlue turns into ammonia (NH3) at high temperatures. This ammonia reacts with NOx in the SCR catalyst and turns into harmless nitrogen (N2) and water vapor (H2O).
Emission Reduction: This process significantly reduces NOx emissions, minimizing harmful gases released into the environment.

COMPONENTS OF ADBLUE (Diesel Exhaust Fluid)

  • Adblue tank
  • Adblue pump
  • Adblue injector
  • Adblue temp and NOX sensors
  • Adblue catalyst
  • Adblue heaters

PROBLEMS OF ADBLUE (Diesel Exhaust Fluid)

  • Limp mode problem
  • Malfunction light coming on (Check Engine Light)
  • Adblue lamp remains on
  • AdBlue range warning on dashboard
  • Increase in emission values
  • Low engine performance
  • The vehicle won't start

NUOVOLTA SOLUTION OF ADBLUE (Diesel Exhaust Fluid)

  • Official diagnostic tool must reset the relevant module.
  • DTC codes should be read and removed with a diagnostic tool
  • Apply the solution of the module related to NUOVOLTA
  • Write the mod file to the ECU
  • Check the dashboard and DTC logs. Take it for a test drive
  • If all the checks are OK, it means the problem is solved
