Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk abin hawa tun 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, da sauransu). Kodayake gabaɗaya a yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Idan motarka ta nuna injin injin ba da daɗewa ba lambar nuna alamar sabis P245E, tsarin sarrafa wutar lantarki (PCM) ya gano rashin aiki a cikin da'irar lantarki na firikwensin matsa lamba na DPF, wanda aka sanya wa B. A bayyane yake, wannan lambar yakamata a gabatar da ita kawai a cikin motocin da dizal injiniya.

An tsara DPF don cire kashi casa'in cikin dari na sinadarin carbon (toka) daga iskar gas mai guba. Soot galibi ana alakanta shi da hayaƙin baƙar fata wanda ke fitowa daga hayaƙin hayaƙi yayin da injin dizal yake cikin hanzari. DPF ɗin yana cikin kwandon shara mai haɗe da ƙarfe wanda yayi kama da murfi ko mai juyawa. Yana can saman canjin mai jujjuyawa da / ko tarkon NOx. Yayin da manyan ɓoyayyen toka ke makale a cikin ɓangaren DPF, ƙananan barbashi da sauran mahadi (iskar gas) na iya ratsa ta. DPF yana amfani da nau'ikan abubuwan haɗin abubuwa daban -daban don tarko toka da wuce iskar gas. Waɗannan sun haɗa da takarda, firam ɗin ƙarfe, firam ɗin yumbu, firam ɗin bangon silicone, da fibers na bango.

Cordierite wani nau'in tacewa ne na yumbu da mafi yawan nau'in fiber da ake amfani da su a cikin matatun DPF. Yana da ƙarancin tsada kuma yana da kyawawan halayen tacewa. Abin takaici, cordierite yana da matsalolin narkewa a yanayin zafi mai yawa, yana sa ya zama mai saurin gazawa lokacin amfani da tsarin tacewa mara kyau.

Zuciyar kowane irin tacewa shine abin tacewa. Lokacin da sharar injuna ta ratsa cikin sinadari, manyan ɓangarorin soot suna makale tsakanin zaruruwa. Yayin da soot ke haɓaka, ƙarfin iskar gas yana ƙaruwa daidai da haka. Da zarar isashen soot ya taru (kuma matsi na shaye-shaye ya kai matakin da aka tsara), dole ne a sake sabunta nau'in tacewa don ba da damar iskar gas ɗin ta ci gaba da wucewa ta cikin DPF.

Tsarin DPF masu aiki suna sabuntawa ta atomatik. A takaice dai, an tsara PCM ɗin don allurar sunadarai (gami da amma ba'a iyakance ga dizal da ruwa mai ɗorewa ba) a cikin iskar gas a cikin lokacin da aka tsara. Wannan aikin yana sa zafin zafin iskar gas ya tashi kuma ƙona ɓoyayyen toka da aka kama; sake su a cikin nau'in nitrogen da ions oxygen.

Ana amfani da irin wannan tsari a cikin tsarin DPF mai wucewa, amma yana buƙatar sa hannun mai shi da (a wasu lokuta) ƙwararren mai gyara. Bayan fara aikin sabuntawa, yana iya ɗaukar sa'o'i da yawa. Sauran tsarin farfadowa na yau da kullun suna buƙatar cire DPF daga abin hawa kuma yana aiki da injin na musamman wanda ke kammala aikin kuma yana cire barbashin so da kyau. Lokacin da aka cire ɓoyayyen ɓoyayyen isasshen, ana ɗaukar DPF ya sake farfadowa kuma dole ne matsin lamba ya amsa daidai.

A mafi yawan lokuta, ana shigar da firikwensin matsa lamba na DPF a cikin injin injin, nesa da DPF. Yana lura da matsin lamba na baya na iskar gas kafin su shiga matattara ta musamman. Ana samun wannan tare da (ɗaya ko fiye) hoses na silicone waɗanda ke da alaƙa da DPF (kusa da mashiga) da firikwensin matsa lamba na DPF.

Lokacin da PCM ta gano yanayin matsin lamba wanda baya cikin ƙayyadaddun masana'anta, ko shigar da wutar lantarki daga firikwensin matsa lamba na DPF B ya wuce iyakokin da aka tsara, za a adana lambar P245E kuma fitilar injin sabis zai yi haske ba da daɗewa ba.

Alamomi da tsanani

Yanayin da aka adana wannan lambar na iya haifar da injin ciki ko lalacewar tsarin mai kuma yakamata a gyara shi nan da nan. Alamomin lambar P245E na iya haɗawa da:

• Hayakin hayaƙi mai yawa daga bututun mai shaye shaye
• Rage aikin injiniya
• Ƙara yawan zafin jiki na injin
• Mafi girman yanayin watsawa

dalilai

Dalilai masu yiwuwa don saita wannan lambar:

• Tashar tafkin ruwa na injin dizal babu komai.
• Ba daidai ba Ruwan Haɗar Diesel
• Raunin firikwensin matsa lamba na DPF
• DPF matattarar firikwensin matsin lamba / hoses sun toshe
• Buɗewa ko gajarta kewaye a cikin firikwensin matsa lamba na DPF B
• Rarrabawar DPF mara tasiri
• Tsarin aikin farfadowa na DPF mara aiki

Hanyoyin bincike da gyara

Kyakkyawan farawa shine koyaushe bincika takaddun sabis na fasaha (TSB) don takamaiman abin hawa. Matsalar ku na iya zama sanannen batun tare da sanannen gyaran masana'anta kuma yana iya adana ku lokaci da kuɗi yayin bincike.

Don tantance lambar P245E, zaku buƙaci na'urar bincike, volt / ohmmeter na dijital, da littafin sabis daga mai ƙera. Hakanan thermometer na infrared zai iya zuwa da kyau.

Yawancin lokaci ina fara ganina ta hanyar duba abubuwan haɗin gwiwa da masu haɗawa. Zan ba da kulawa ta musamman ga wayoyin da ake biye da su kusa da abubuwan da ke shaye shaye masu zafi da gefuna masu kaifi. Duba tashoshin baturi da baturi a wannan lokacin kuma duba fitowar janareta.

Sannan na haɗa na'urar daukar hotan takardu kuma na sami duk lambobin da aka adana da daskare bayanan firam. Zan rubuta wannan don amfanin gaba. Wannan na iya zama da amfani idan wannan lambar ta zama ta ɓace. Yanzu share lambobin kuma gwada fitar da abin hawa.

Idan lambar ta sake farawa nan da nan, bincika cewa injin mai ƙona injin diesel (idan an zartar) yana nan kuma yana daidai. Mafi yawan dalilin da yasa aka adana wannan lambar shine rashin iskar gas ɗin injin dizal. Ba tare da madaidaicin nau'in murfin injin din diesel ba, DPF ba za a sake sabunta shi da kyau ba, wanda zai haifar da yuwuwar hauhawar matsin lamba.

Koma zuwa littafin sabis na mai ƙira don umarnin kan yadda za a gwada firikwensin matsa lamba na DPF ta amfani da DVOM. Idan firikwensin bai cika buƙatun juriya na masana'anta ba, dole ne a maye gurbinsa. Idan firikwensin yayi kyau, duba DPF matattarar firikwensin samar da bututu don toshewa da / ko karya. Tsaftace ko maye gurbin hoses idan ya cancanta. Dole ne a yi amfani da manyan bututun silicone masu zafi.

Idan firikwensin yana da kyau kuma layukan wutar lantarki suna da kyau, fara gwada da'irar tsarin. Cire duk hanyoyin sarrafawa masu alaƙa kafin gwada juriya da / ko ci gaba tare da DVOM. Gyara ko maye gurbin da'irori masu buɗewa ko gajarta kamar yadda ya cancanta.

Ƙarin bayanin kula:

• Idan hoses na firikwensin matsa lamba na DPF sun narke ko sun fashe, yana iya zama dole a sake komawa hanya bayan sauyawa.
• Tuntuɓi littafin maigidan / sabis don bincika ko abin hawa yana sanye da tsarin farfadowa na DPF mai aiki ko tsarin wucewa.
• Kunshe tashoshin firikwensin da bututun firikwensin firikwensin na kowa

Tattaunawar DTC mai dangantaka

• A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.

Kuna buƙatar ƙarin taimako tare da lambar p245E?

Idan har yanzu kuna buƙatar taimako tare da DTC P245E, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.
