Ukusebenza ngempumelelo kwe-P2001 NOx Ngezansi kweThreshold Bank 2
Idatha ye-OBD-II DTC
Ukusebenza kahle kwe-NOx Ngezansi kweThreshold, iBhange 2
Kusho ukuthini lokhu?
Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto zango-1996 (iNissan, Honda, Infiniti, Ford, Dodge, Acura, Toyota, njll.). Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.
I-P2001 egciniwe isho ukuthi i-powertrain control module (PCM) ithole ileveli ye-nitrogen oxide (NOx) eyeqa umkhawulo ohleliwe. I-Bank 2 isho ohlangothini lwenjini olungenayo isilinda # 1.
Injini yomlilo ikhipha i-NOx njengegesi yokukhipha. Izinhlelo zokuguqula izinto, ezisetshenziselwa ukunciphisa ukukhishwa kwe-NOx ezinjinjini eziphehla igesi, azisebenzi kahle ezinjinini zikadizili. Lokhu kungenxa yokuqukethwe okuphezulu komoya-mpilo kumagesi okukhipha izinjini zikadizili. Njengendlela yesibili yokubuyiselwa kwe-NOx ezinjinini zikadizili, kufanele kusetshenziswe isicupho se-NOx noma uhlelo lwe-NOx adsorption. Izimoto zikadizili zisebenzisa amasistimu we-Selective Catalytic Reduction (SCR), okuyingxenye yomgibe we-NOx.
I-Zeolite isetshenziselwa ukubamba ama-molecule we-NOx ukuwavimbela ukuthi angakhishelwa emoyeni. Iwebhu yamakhemikhali e-zeolite aboshelwe ngaphakathi kwendlu ebukeka njengesiguquli se-catalytic. Amagesi okukhipha adlula ngendwangu futhi i-NOx ihlala ngaphakathi.
Ukuvuselela ukwakheka kwe-zeolite, amakhemikhali avuthayo noma avuthayo ajovwa ngohlelo lokujova olulawulwa ngogesi. Amakhemikhali ahlukahlukene asetshenziselwe le njongo, kepha udizili yiwona osebenza kakhulu.
Ku-SCR, izinzwa ze-NOx zisetshenziswa ngendlela efanayo nezinzwa zomoya-mpilo ezinjinini zikaphethiloli, kepha azithinti isu lokuzivumelanisa nophethiloli. Baqapha izinhlayiya ze-NOx esikhundleni samazinga e-oxygen. I-PCM iqaphe idatha kusuka kuzinzwa ze-NOx ngaphambi nangemva kokufaka ukubala ukusebenza ngokutakula kwe-NOx. Le datha isetshenziswa futhi nesu lokulethwa kwe-liquid NOx reductant.
Umenzeli wokwehliswa ujovwa kusetshenziswa umjovo olawulwa ngekhompyutha kusuka kwi-PCM noma imodyuli ye-SCR. Idamu elikude liqukethe i-NOx reductant / diesel enamanzi; ifana nethangi likaphethiloli elincane. Ingcindezi enqamulelayo yenziwa yimpompo kaphethiloli elawulwa ngogesi.
Uma i-PCM ithola ileveli ye-NOx edlula umkhawulo ohleliwe webhange 2, kuzogcinwa ikhodi engu-P2001 bese kuthi isibani sesikhombisi esingasebenzi kahle sikhanye.
izimpawu
Izimpawu zekhodi ye-P2001 zingafaka:
- Intuthu eyeqile kusuka ekuqothulweni kwenjini
- Kwehliswe ukusebenza kwenjini ngokuphelele
- Ukushisa kwenjini okwandisiwe
- Ukunciphisa ukusebenza kwephethiloli
izizathu
Izimbangela ezingaba khona zale khodi yenjini zifaka:
- Isicupho se-NOx esinamaphutha noma esigcwele ngokweqile noma isici sesicupho se-NOx
- Iphutha le-diesel exhaust fluid injection system
- I-NOx engafanele noma engafanele yokunciphisa uketshezi
- Isistimu yokubuyiswa kwegesi engasebenzi
- Ukuvuza okukhulu kwegesi okukhiphayo phambi kwesicupho se-NOx
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.
Ukuthola ikhodi ye-P2001, uzodinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wolwazi lwemoto njenge-All Data (DIY).
Ngingaqala ngokubheka ngamehlo wonke amahhanisi nezintambo ezisohlelweni. Gxila ezintanjeni eduze kwezakhi zohlelo lokushisa okushisayo kanye namaphiko abukhali wokukhipha, ikakhulukazi kuBlock 2.
Bheka uhlelo lokukhipha ukuvuza nokungalungisi uma kunesidingo.
Qiniseka ukuthi ithangi le-SCR liqukethe okwehliswayo futhi elisezingeni elifanele. Landela izincomo zomkhiqizi lapho ungeza uketshezi olwehlisayo.
Hlola ukusebenza kohlelo lokukhipha igesi lokukhipha ugesi nge-scanner. Buyisela wonke amakhodi e-EGR agciniwe ngaphambi kokuzama ukuthola le khodi.
Buyisa wonke ama-DTC agciniwe bese uqandisa idatha yozimele ngokuxhuma isithwebuli esikhumulweni semoto sokuxilonga. Bhala phansi lolu lwazi; lokhu kungasiza ekutholeni ikhodi yezikhathi ezithile. Sula amakhodi ohlelweni bese uqala injini. Ngingavumela injini ifinyelele ekushiseni okujwayelekile kokusebenza bese ngivivinya ukushayela imoto ukubona ukuthi ikhodi isuliwe yini.
Uma isethwe kabusha, xhuma isithwebuli bese ugcina idatha yenzwa ye-NOx. Nciphisa ukusakaza kwakho kwedatha ukufaka imininingwane efanele kuphela futhi uzothola imininingwane enembile kakhulu.
Uma ngabe iyiphi inzwa ye-NOx ingasebenzi, hlola i-fuse efuthwe egumbini lenjini noma ngaphansi kwedeshibhodi. Izinzwa eziningi ze-NOx zenziwe ngocingo olungu-4 olunentambo yamandla, ucingo oluphansi nezintambo ezinamasiginali amabili. Sebenzisa i-DVOM ne-manual manual (noma yonke idatha) ukuhlola amandla wamandla webhethri namasiginali womhlaba. Bheka isignali yokukhipha inzwa enjinini ekushiseni okujwayelekile kokusebenza nangejubane elingenzi lutho.
Amanothi wokuxilonga angeziwe:
- Ukukhetha okungalungile noma ukuntuleka koketshezi olunqanda ukuguga yisizathu esivame kakhulu sokuthi ikhodi ye-P2001 igcinwe.
- Ukuqeda i-valve ye-EGR imvamisa kuyisizathu sokungasebenzi kahle kwesicupho se-NOx.
- Ukusebenza okuphezulu ngemuva kwezimpawu zohlelo lokukhipha uhlelo nakho kungaholela kwisitoreji se-P2001
Izingxoxo ezihlobene ze-DTC
- Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.
Udinga usizo olwengeziwe ngekhodi engu-P2001?
Uma usadinga usizo nge-DTC P2001, 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.
