Idatha ye-OBD-II DTC

Ukusebenza kwesihlungi se-Diesel Particulate Ngezansi kweThreshold Bank 2

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Yokuhlola (i-DTC) yikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (ngo-1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

I-DTC ibhekisa kudivayisi yokulawula ukungcola ebizwa ngesihlungi se-particulate. Kufakwe ngo-2007 nakuma-diesel kamuva, kuqeda umule emagesi abo okukhipha. Cishe uzoyibona le DTC ku-Dodge, Ford, Chevrolet noma i-GMC picking trucks, kodwa futhi ingasebenza nakwezinye izimoto zikadizili ezifana ne-VW, Vauxhall, Audi, Lexus, njll.

I-DPF - isihlungi se-diesel particulate - sithatha uhlobo lwesiguquli se-catalytic futhi sitholakala ohlelweni lwe-exhaust. Ngaphakathi kune-matrix yezinhlanganisela ezimboza amavesi njenge-cordierite, i-silicon carbide, nemicu yensimbi. Ukusebenza kahle kokususwa kwensisi kungama-98%.

Isithombe esinqunyiwe sesihlungi se-particulate (DPF):

I-DPF idala ingcindezi encane emuva ngesikhathi sokusebenza. I-ECU yemoto - ikhompuyutha - inezinzwa zempendulo yengcindezi kusihlungi se-particle ukuze ilawule ukusebenza kwayo. Uma nganoma yisiphi isizathu - emijikelezweni emibili yomsebenzi - ithola ukungezwani phakathi kwebanga lokucindezela, ibeka ikhodi P2003 ekhombisa iphutha.

Ungakhathazeki, lawa madivayisi anekhono lokuzivuselela lokushisa insizi enqwabelene futhi abuyele emsebenzini ojwayelekile. Zihlala isikhathi eside.

Uma lokhu sekwenzekile, izibani zizocisha futhi ikhodi izosula. Kungakho ibizwa ngekhodi yohlelo - ikhombisa iphutha "ngesikhathi sangempela" futhi iyalisula njengoba iphutha lilungiswa. Ikhodi eqinile ihlala kuze kube yilapho ukulungiswa kuqedwa futhi ikhodi ikhishwa ngesandla kusetshenziswa isithwebuli.

Zonke izimoto zidinga ithuluzi lokususa i-nitrogen oxides ekhishwe emkhathini, ebingeke ibe khona futhi eyingozi empilweni yakho nasemoyeni. Isiguquli se-catalytic sinciphisa ukukhishwa okuvela ezinjini zikaphethiloli. Ngakolunye uhlangothi, udizili unenkinga enkulu.

Njengoba ukushisa kukaphethiloli ocindezelwe kakhulu kusetshenziselwa ukuvutha ngokuzenzekelayo, izinga lokushisa kuma-cylinder heads liphezulu kakhulu, okudala indawo engathi sína yokuzalanisa i-nitrogen oxide. I-NOx yakheka emazingeni okushisa aphezulu kakhulu. Onjiniyela babazi ukuthi badinga ukusebenzisa i-EGR - Exhaust Gas Recirculation - ukuze banciphise uphethiloli ongenayo ukuze behlise izinga lokushisa ekhanda futhi banciphise ukukhishwa kwe-NOx. Inkinga yayiwukuthi izinga lokushisa likadizili laliphezulu kakhulu futhi lenza inkinga yaba nzima kakhulu.

Bakulungisa lokhu ngokusebenzisa isipholile senjini ukupholisa uwoyela wenjini kanye nepayipi le-EGR ukuze kugcinwe izinga lokushisa lekhanda lesilinda lingaphansi kwalelo elalidinga ukwenza i-NOx. Isebenze kahle kakhulu. I-DPF iwumugqa wokugcina wokuzivikela ekukhiqizweni ngokususa umule.

QAPHELA. Le DTC P2003 iyefana ne-P2002, kepha i-P2003 isebenza ebhange 2, okuluhlangothi lwenjini olungenayo isilinda # 1.

izimpawu

Izimpawu zekhodi yenkinga ye-P2003 zingafaka:

• Ukwehla komnotho kaphethiloli kwenzeka lapho uhlelo lokuphathwa kwezinjini luzama ukukhuphula izinga lokushisa kwamagesi okukhipha umlilo ukuze kushe insizi eyeqile ku-DPF.
• Ilambu lenjini yesheke elinekhodi P2003 lizokhanyisa. Isibani singahlala sikhanyisiwe noma sikhanyiswe ngezikhathi ezithile ngesikhathi sokuvuselelwa kwe-DPF. Injini izonqena uma ishesha.
• Uwoyela wenjini uzokhombisa ukuxubeka ngenxa yama-ECM azama ukukhuphula izinga lokushisa kwenjini. Ezinye izimoto zihamba kancane ngemuva kwesikhungo esiphezulu ukushisa inani elincane likaphethiloli ukukhuphula izinga lokushisa kwamagesi okukhipha. Amanye alawa mafutha angena esikhwameni sokuthwala. Lapho i-ECM inquma isidingo sokuvuselelwa kwe-DPF, impilo kawoyela yehliswa kakhulu.
• Uma i-DPF ingasuswa, i-ECU izobuyela ku- "Limp Home Mode" kuze kube yilapho isimo silungiswa.

Izizathu ezingenzeka

Izizathu zale DTC zingafaka:

• Le khodi izodala isivinini esincane kakhulu. Ukuze ushise umule ku-DPF kudinga ukushisa okubalelwa ku-500 ° C kuye ku-600 ° C. Ngisho nangemizamo ye-ECU yokulawula injini, kunzima kuyo ukukhiqiza ukushisa okwanele ukuhlanza i-DPF ngesivinini senjini ephansi.
• Ukuvuza komoya phambi kwe-DPF kuzoshintsha ukufundwa kwenzwa, okuholela kukhodi
• Amasu angalungile noma izingxenye ze-ECU zivimbela ukuvuselelwa okufanele.
• Okokhelekayo okunesibabule esikhulu kuvala i-DPF ngokushesha
• Ezinye izesekeli ze-aftermarket nokuguqulwa kokusebenza
• Isici sesihlungi somoya esingcolile
• I-DPF eyonakele

Izinyathelo zokuxilonga kanye nezixazululo ezingaba khona

Izixazululo zikhawulelwe ngandlela thile njengoba i-DPF ingenasici, kepha igcwele okwesikhashana ngezinhlayiya zomsizi. Uma ilambu likhanya futhi nekhodi ye-P2003 isethiwe, landela inqubo yokuxazulula inkinga ngokuqala ngokuhlola okubukwayo.

Hlola i-DPF kubhlokhi # 2 nganoma yikuphi ukuxhumana okuxekethile ohlangothini lwenjini lapho kunamathela khona kumbhobho wokukhipha.

Hlola ngokubonakalayo i-DPF ngaphambili nangemuva kwama-transducers wokucindezela umahluko (block 2). Bheka izintambo ezishisiwe, izixhumi ezikhululekile noma ezonakalisiwe. Nqamula izixhumi bese ubheka izikhonkwane ezigoqiwe noma ezonakalisiwe. Qiniseka ukuthi izintambo zenzwa azithinti i-DPF. Qala isilayishi bese ubheka ukuvuza kumshini noma eduze kwawo.

Uma konke kuhamba kahle ngezinyathelo ezingenhla, shayela iloli cishe imizuzu engama-30 ngejubane lomgwaqo ukukhuphula izinga lokushisa kwegesi okuphezulu ngokwanele ukuvuselela i-DPF. Ngokwami, ngithole ukuthi ukufaka idling injini nge-1400 rpm cishe imizuzu engama-20 kunikeza imiphumela efanayo.

Uma inkinga isaqhubeka ngemuva kokushayela ngejubane lomgwaqo omkhulu, kungcono uye nayo esitolo ubacele ukuthi bayifake kukhompyutha yokuxilonga efana neTech II. Akubizi futhi bangaqapha izinzwa nama-ECU ngesikhathi sangempela. Bangabona amasiginali avela kuzinzwa futhi babheke ukuthi ngabe i-ECU empeleni izama ukuvuselela kabusha. Ingxenye embi ivele ngokushesha.

Uma uhamba uzungeza idolobha futhi lokhu kuyinkinga ephindaphindekayo, kunesinye isixazululo. Izitolo eziningi zingaphinde zenze kabusha ikhompyutha yakho ukuvimbela inqubo yokuzivuselela kumasekhondi ambalwa. Ngemuva kwalokho susa i-PDF bese uyifaka esikhundleni ngepayipi eliqondile (uma livunyelwe endaweni yakho). Inkinga isixazululiwe. Ungayilahli i-DPF noma kunjalo, kubiza imali eningi uma uyithengisa noma uyidinga ngokuzayo.

QAPHELA. Ukuguqulwa okuthile okufana namakhithi e- "cold air intake" (CAI) noma ama-exhaust kits kungadala le khodi futhi kungathinta newaranti yomkhiqizi. Uma unokuguqulwa okunjalo nale khodi, buyisela ingxenye ephindayo endaweni bese ubona ukuthi ikhodi iyanyamalala. Noma zama ukuxhumana nomakhi wezikhwama ukuthola izeluleko zokubona ukuthi lolu udaba olwaziwayo yini.

Izingxoxo ezihlobene ze-DTC

• Ikhodi yephutha P2003 yeNissan Altima 2007 3.5Eyami i-nissan altima 2007 3.5 SE. Ukhombise uphawu lwesevisi yenjini kwathi uma ngikhuluma nomakhenikha waqhamuka nephutha le-P2003. Kodwa uthi kuyamangaza ukuthola leyo khodi yemoto kaphethiloli. Ngidinga usizo ukuze ngithole ukuthi yini. 🙄: ukugoqa:... 

Udinga usizo olwengeziwe ngekhodi le-p2003?

Uma usadinga usizo nge-DTC P2003, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
