Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk motocin 1996 (Nissan, Honda, Infiniti, Ford, Dodge, Acura, Toyota, da sauransu). Kodayake gabaɗaya a yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

P2001 da aka adana yana nufin tsarin sarrafa wutar lantarki (PCM) ya gano matakin nitrogen oxide (NOx) wanda ya wuce iyakar da aka tsara. Bankin 2 yana nufin gefen injin wanda baya ɗauke da silinda # 1.

Injin konewa yana fitar da NOx a matsayin iskar gas. Tsarin musanyawa na catalytic, waɗanda ake amfani da su don rage gurɓataccen iska na NOx a cikin injunan da ke amfani da iskar gas, ba su da inganci a cikin injunan dizal. Wannan ya faru ne saboda yawan iskar oxygen a cikin iskar gas na injunan dizal. A matsayin hanya ta biyu don dawo da NOx a cikin injunan diesel, dole ne a yi amfani da tarkon NOx ko tsarin talla na NOx. Motocin Diesel suna amfani da tsarin Zaɓin Rage Rage Rage (SCR), wanda tarkon NOx ya ƙunshi.

Ana amfani da Zeolite don tarko kwayoyin NOx don hana a sake su cikin yanayi. Gidan yanar gizo na mahadi na zeolite yana makale a cikin wani gida wanda yayi kama da mai canzawa. Iskar gas na wucewa ta cikin zane kuma NOx ya kasance a ciki.

Don sabunta tsarin zeolite, ana yin allurar sunadarai masu ƙonewa ko ƙonewa ta hanyar tsarin allura mai sarrafa lantarki. Anyi amfani da sunadarai iri -iri don wannan dalili, amma dizal shine mafi amfani.

A cikin SCR, ana amfani da firikwensin NOx daidai da na firikwensin oxygen a cikin injunan mai, amma ba sa shafar dabarun daidaita man. Suna kula da barbashin NOx maimakon matakan oxygen. PCM yana kula da bayanai daga firikwensin NOx kafin da bayan mai haɓaka don ƙididdige ingancin dawo da NOx. Hakanan ana amfani da wannan bayanan a cikin dabarun isarwa na mai rage ruwa NOx.

Ana allurar wakilin ragewa ta amfani da injector wanda ke sarrafawa ta hanyar lantarki daga PCM ko tsarin SCR. A tafki mai nisa ya ƙunshi ruwa NOx rage / dizal; yayi kama da karamin tankin mai. Ana haifar da matsi mai raguwa ta hanyar famfon mai sarrafa wutar lantarki.

Idan PCM ta gano matakin NOx ya wuce iyakar da aka tsara don banki 2, za a adana lambar P2001 kuma fitilar mai nuna rashin aiki na iya haskakawa.
