Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gabaɗaya kuma ta shafi yawancin motocin OBD-II (1996 da sabuwa). Wannan na iya haɗawa amma ba'a iyakance ga Mercedes, Sprinter, Ford, GMC, Chevrolet, da dai sauransu Yayin janar, ainihin matakan gyara na iya bambanta dangane da shekarar ƙirar, ƙirar, ƙirar da tsarin watsawa.

Tsarin mai haɓakawa yana da alhakin rage (galibi) duk iskar da ke fitarwa, kodayake wasu aikace -aikacen kuma suna sanye da tarkon NOx.

Tsarin sake dawo da iskar Gas (EGR) ya ɗauki wani mataki na rage fitar da hayaƙi na NOx. Koyaya, manyan injunan diesel na yau ba za su iya cika ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan ƙawancen tarayya (US) tare da kawai EGR, DPF / catalytic converter, da NOx trap. A saboda wannan dalili, an ƙirƙiri tsarin rage yawan kuzari (SCR).

Tsarin SCR suna allurar tsarin ragewa ko Diesel Exhaust Fluid (DEF) a cikin iskar gas ɗin da ke saman matattara mai rarrafe, tarkon NOx da / ko mai jujjuyawa ta hanyar bawul ɗin allurar ragewa (solenoid). Allurar da aka lissafa daidai DEF tana ɗaga zafin zafin abun tace kuma tana ba shi damar yin aiki da inganci. Yana ƙara tsawon rayuwar sabis na abubuwan tacewa kuma yana taimakawa rage fitar da gurɓatattun iskar gas mai haɗari zuwa cikin yanayi. Duk tsarin SCR ana sarrafawa da sa ido ta ko dai PCM ko mai tsayawa kai tsaye (wanda ke hulɗa da PCM). A kowane hali, mai kulawa yana lura da O2, NOx da firikwensin zafin zafin gas (gami da sauran abubuwan shiga) don ƙayyade lokacin da ya dace don allurar DEF (rage). Ana buƙatar allurar DEF madaidaiciya don kiyaye zafin iskar gas a cikin abubuwan da aka yarda da su da kuma inganta tacewar gurɓatattun abubuwa.
