Mene ne wannan yake nufi?

Wannan sigar lambar rikitarwa ce mai rikitarwa (DTC) kuma galibi ana amfani da ita ga motocin OBD-II. Alamar mota na iya haɗawa, amma ba'a iyakance ta ba, Mercedes-Benz, Sprinter, VW, Audi, Ford, Dodge, Ram, Jeep, da sauransu.

NOx (nitrogen oxide) ana amfani da na'urori masu auna firikwensin don tsarin hayaki a cikin injunan diesel. Babban manufar su shine ƙayyade matakan NOx da ke fitowa daga iskar gas bayan konewa a cikin ɗakin konewa. Sannan tsarin yana sarrafa su ta hanyar amfani da hanyoyi daban-daban. Idan aka yi la'akari da yanayin aiki na waɗannan na'urori masu auna firikwensin, an yi su ne da haɗin yumbu da wani takamaiman nau'in zirconia.
