What is an SCR system ?

SCR - selective catalytic reduction -this system converts nitrogen oxides (NOx) to N2 and H2O. The NOx reduction reaction takes place with injecting AdBlue(DEF) into catalytic converter.

The system consists of the following elements:

• Urea Reservoir (AdBlue-DEF)
• heaters (preventing freezing of liquid during negative temperatures)
• pump
• Injector (located in the catalyst)
• NOx sensor (located at the end of the SCR system)
