SCR – a urea-based solution.

SCR / 2012 / de+en

SCR stands for selective catalytic reduction. A chemical reaction converts nitrogen oxides to water and pure nitrogen. The conversion process is aided by a synthetically produced, diluted urea solution (AdBlue®) delivered via a separate storage tank. The advantage of SCR technology is an optimal combustion process within the engine coupled with increased efficiency. A second tank system for AdBlue® needs to be installed in the vehicle. The necessary equipment as well as the delivery and replenishment of the urea solution itself mean additional costs associated with using this technology.

  1. Charge-air cooler
  2. Air filter
  3. Dosing and control module
  4. Urea tank
  5. DOC
  6. Injector
  1. AdBlue®: 32.5 % urea/water solution
  2. Electronically controlled injection of AdBlue® into exhaust gas flow (approx. 3–7 % of diesel volume)
  3. Engine exhaust gas flow
  4. High temperature converts urea to ammonia
  5. Ammonia and NOx react in SCR catalytic converter to yield nitrogen and water
  6. To exhaust pipe
