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)
- Injector (located in the catalyst)
- NOx sensor (located at the end of the SCR system)
