Menene Sensor NOx?

Firikwensin NOx wani ɓangare ne na tsarin rage NOx bayan magani da ake amfani da shi a cikin motocin dizal tare da tsarin SCR na tushen urea. Na'urar firikwensin da ke sama na mai kara kuzarin SCR kai tsaye yana auna ma'aunin iskar gas na NOx, wanda ke taimakawa tantance mafi girman adadin allurar urea. Ana amfani da firikwensin NOx a ƙasa na mai kara kuzari na SCR don saka idanu akan aikin mai kara kuzari.
