Selective Catalytic Reduction (SCR)

Engines designed for SCR systems apply higher fuel injection pressure and optimize combustion for better fuel economy and response. This decreases PM formation but increases the amount of NOx in the exhaust. The exhaust gas is treated by injecting a urea solution, AdBlue®, into the exhaust flow. This turns the NOx in the exhaust gas into nitrogen and water which are harmless for the environment.


SCR characteristics

  • • Reduced PM by engine design
  • • Better fuel efficiency
  • • Compact technology and easy to install
  • • AdBlue® product well known and widely available
  • • No regeneration required
