Udizili Particulate Hlunga B Pressure Inzwa Circuit

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto kusukela ngo-1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, njll.). Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Uma imoto yakho ibonisa injini yesikhombi se-service code P245E kungekudala, i-powertrain control module (PCM) ithole ukungasebenzi kahle kugesi kagesi we-DPF pressure sensor, obizwa nge-B. Ngokusobala, le khodi kufanele yethulwe kuphela ezimotweni ezinedizili injini.

I-DPF yenzelwe ukususa amaphesenti ayisishiyagalolunye ezinhlayiya zekhabhoni (insizi) emagesi aqeda udizili. Umsila uvame ukuhlotshaniswa nentuthu emnyama ephuma emsini wokukhipha lapho injini kadizili ingaphansi kokusheshisa okuqinile. I-DPF ibekwe esikhwameni sensimbi esakhelwe ngaphakathi esifana nesiguquli esingaguquki noma esiguquguqukayo. Itholakala enhla nomguquli wokuguqula kanye / noma noxhaka we-NOx. Ngenkathi izinhlayiya ezinkulu zomsizi zibhajwe entweni ye-DPF, izinhlayiya ezincane namanye amakhemikhali (amagesi e-exhaust) angadlula kuyo. I-DPF isebenzisa izinhlobo ezahlukahlukene zamakhemikhali okubamba umusi nokudlulisa amagesi wokukhipha injini. Lokhu kufaka phakathi iphepha, imicu yensimbi, imicu ye-ceramic, imicu yodonga lwama-silicone, nezintambo zodonga lwe-cordierite.

I-Cordierite iwuhlobo lokuhlunga okusekelwe ku-ceramic kanye nohlobo oluvame kakhulu lwefayibha esetshenziswa kuzihlungi ze-DPF. Ayibizi futhi inezici ezinhle kakhulu zokuhlunga. Ngeshwa, i-cordierite inezinkinga zokuncibilika emazingeni okushisa aphezulu, okuyenza ijwayele ukwehluleka uma isetshenziswa ezinhlelweni zokuhlunga eziyizinhlayiyana.

Inhliziyo yanoma yisiphi isihlungi sezinhlayiya isici sokuhlunga. Lapho i-exhaust yenjini idlula endaweni, izinhlayiya ezinkulu ze-soot zivaleleka phakathi kwemicu. Njengoba i-soot ikhula, umfutho wegesi yokukhipha ukhuphuka ngokufanele. Uma umule owanele usuqoqiwe (futhi nomfutho we-exhaust usufinyelele izinga elihleliwe), isici sokuhlunga kufanele sivuselelwe ukuze kuvunyelwe amagesi e-exhaust ukuthi aqhubeke edlula ku-DPF.

Izinhlelo ezisebenzayo ze-DPF zivuselelwa ngokuzenzakalela. Ngamanye amagama, i-PCM ihlelelwe ukufaka amakhemikhali (kufaka phakathi kepha kungagcini kudizili nokukhipha uketshezi) kumagesi okukhipha ngezikhathi ezihleliwe. Lesi senzo senza ukuthi izinga lokushisa kwamagesi okukhipha umoya likhuphuke futhi izinhlayiya zomsizi ezibhajwe zishiswe; ukuzikhulula ngesimo se-nitrogen ne-oxygen ions.

Inqubo efanayo isetshenziswa ezinhlelweni ezingenzi lutho ze-DPF, kepha idinga ukubandakanyeka komnikazi futhi (kwezinye izimo) umlungisi oqeqeshiwe. Ngemuva kokuqala kwenqubo yokuvuselela, kungathatha amahora ambalwa. Ezinye izinhlelo zokuvuselela okungenzi lutho zidinga ukuthi i-DPF isuswe emotweni futhi ihlinzekwe ngumshini okhethekile oqeda inqubo futhi asuse kahle izinhlayiya zomsizi. Lapho izinhlayiya zomsizi zisuswe ngokwanele, i-DPF ibhekwa njengokuvuselelwa futhi ingcindezi ye-exhaust kufanele iphendule ngokufanele.

Ezimweni eziningi, inzwa yengcindezi ye-DPF ifakwa egumbini lenjini, kude ne-DPF. Ihlola ingcindezi yangemuva yamagesi aqeda ngaphambi kokufaka isihlungi se-particulate. Lokhu kutholakala ngamathumbu abicah (okukodwa noma ngaphezulu) axhunywe kwi-DPF (eduze ne-inlet) kanye ne-DPF sensor sensor.

Lapho i-PCM ithola isimo sengcindezi yokukhipha engekho ngaphakathi kokucacisiwe komkhiqizi, noma okokufaka kagesi kusuka ku-DPF B sensor sensor kudlula imikhawulo ehleliwe, ikhodi ye-P245E izogcinwa futhi isibani senjini yensizakalo sizokhanyisa kungekudala.

Izimpawu nobukhali

Izimo eligcinelwe le khodi zingaholela ekulimaleni kwenjini noma kohlelo lukaphethiloli futhi kufanele zilungiswe ngokushesha. Izimpawu zekhodi ye-P245E zingafaka:

• Intuthu emnyama eyeqile iphuma epayipini lokukhipha
• Ukunciphisa ukusebenza kwenjini
• Ukushisa kwenjini okwandisiwe
• Amazinga wokushisa aphezulu

izizathu

Izizathu ezingaba khona zokusetha le khodi:

• Isiziba sedizili yokukhipha injini yedizili asinalutho.
• Uketshezi Lokukhipha Udizili olungalungile
• Inzwa yengcindezi eyiphutha ye-DPF
• Amashubhu we-DPF sensor sensor / hoses avalekile
• Isifunda esivulekile noma esifushane kusifunda se-DPF pressure sensor B
• Ukuvuselelwa kabusha kwe-DPF okungasebenzi
• Uhlelo lokuvuselelwa olusebenzayo lwe-DPF

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Ukuxilonga ikhodi ye-P245E, uzodinga isithwebuli sokuxilonga, i-digital volt / ohmmeter, kanye nencwadi yemisebenzi evela kumenzi. I-thermometer ye-infrared nayo ingasebenza kahle.

Imvamisa ngiqala ukuxilongwa ngokuhlola ngamehlo amahhanisi nezixhumi ezihambisanayo. Nginganaka ngokukhethekile i-wiring ehanjiswa eceleni kwezingxenye zokushisa okushisayo nemiphetho ebukhali. Bheka okhethweni bebhethri nebhethri ngalesi sikhathi bese uhlola umphumela we-generator.

Ngibe sengixhuma isithwebuli ngathola wonke amakhodi agciniwe futhi ngafriza idatha yozimele. Lokhu ngikubhala phansi ukuze ngisetshenziswe esikhathini esizayo. Lokhu kungasebenziseka uma le khodi kuvela ukuthi iphakathi. Manje sula amakhodi bese uhlola ukushayela imoto.

Uma ikhodi isethwa kabusha ngokushesha, hlola ukuthi uketshezi lwenjini edonsa ngodizili lukhona (uma lukhona) nokuthi luhlobo oluyilo yini. Isizathu esivame kakhulu ukuthi le khodi igcinwe ukungabi khona kuketshezi lwenjini yedizili. Ngaphandle kohlobo olufanele lukadizili okhipha uketshezi lwenjini, i-DPF ngeke ivuselelwe kahle, okuholele ekukhuleni okungaba khona kwengcindezi yokukhipha.

Bheka imanuwali yensizakalo yomkhiqizi ukuthola imiyalo yokuthi ungayivivinya kanjani inzwa yengcindezi ye-DPF usebenzisa i-DVOM. Uma inzwa ingahlangabezani nezidingo zokumelana nomkhiqizi, kufanele ithathelwe indawo. Uma inzwa ilungile, hlola amapayipi wokuhlinzekwa kwenzwa ye-DPF ukuthola ukuvinjelwa kanye / noma amakhefu. Hlanza noma ufake amanye amapayipi uma kudingeka. Kufanele kusetshenziswe amapayipi okushisa abicah aphezulu.

Uma inzwa inhle futhi izintambo zikagesi zilungile, qala ukuhlola amasekethe wesistimu. Nqamula wonke amamojula wokulawula ahambisanayo ngaphambi kokuhlola ukumelana kanye / noma ukuqhubeka ne-DVOM. Lungisa noma shintsha amasekethe avulekile noma afushane lapho kudingeka.

Amanothi wokuxilonga angeziwe:

• Uma ama-hose we-DPF sensor sensor ancibilikile noma aqhekeka, kungadingeka ukuthi uphinde usebenze kabusha ngemuva kokushintshwa.
• Thinta ibhukwana lomnikazi / lesevisi ukuthola ukuthi ngabe imoto yakho inesistimu esebenzayo yokuvuselela kabusha i-DPF noma i-passive system.
• Izimbobo zezinzwa ezivalekile namashubhu enzwa avalekile kuvamile

Izingxoxo ezihlobene ze-DTC

• Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.
