OBD-II DTC Dhata

Superheat catalyst system, bhangi 2

Izvi zvinorevei?

Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekufambisa uye inoshanda kune mazhinji OBD-II mota (1996 uye nyowani). Izvi zvinogona kusanganisira, asi hazvingogumiri ku, Ford, Hino, Mercedes Benz, VW, nezvimwewo. Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nemhando yegore, gadzira, modhi uye kutapurirana kugadzirisa.

Kana kodhi P200F yakachengetwa pamotokari yako yedhiziri yeOBD-II, zvinoreva kuti powertrain control module (PCM) yaona tembiricha yakawandisa yechipiri bank catalyst system. Bank 2 iboka reinjini risina nhamba imwe silinda.

Iyo catalytic system mumotokari yemazuva ano ine injini yedhiziri inomhanya pamafuta ane hushamwari hwezvakatipoteredza yakagadzirirwa kudzikisa anokuvadza emhepo magasi asati apinda mumhepo. Exhaust emissions inosanganisira kunyanya mahydrocarbons (HC), carbon monoxide (CO), nitrogen oxide (NOx) uye particulate matter (soot - in diesel engines). A catalytic converter inonyatso sefa hombe (ine meshes yakanaka) inogona kumira kutonhora kwakanyanya. Exhaust magasi kubva muinjini anopfuura mairi, uye zvinokuvadza zvinobuda zvinobatwa neplatinamu sefa chinhu. Iyo tembiricha yakanyanyisa inogadzirwa mukati meiyo catalytic converter inobatsira kupisa zvinokuvadza zvinobuda.

Iyo catalyst system inoitisa kudzikisira (kunyanya) mamwe ese emafesi emhepo, kunyangwe mamwe mashandisirwo akave akashongedzerwa neNox musungo.

Exhaust Gesi Kutenderera (EGR) masisitimu anotora rimwe danho mukuderedza NOx emissions. Nekudaro, yanhasi makuru, enjini dzedhiziri dzine simba kwazvo hadzigone kusangana nemabatiro akaomarara emubatanidzwa (eUS) neEGR chete, inoshandura inoshandura uye musungo weNOX. Neichi chikonzero, masarudzo akasarudzika ekuderedza (SCR) akagadzirwa.

SCR masisitimu anojekesa Diesel Exhaust Fluid (DEF) mukati memagetsi ekumusoro kumusoro kweiyo firita firita uye / kana chinogadzirisa chinoshandura. Iyo chaiyo yakaverengerwa DEF jekiseni inokwidza tembiricha yechinhu chesefa uye ichiitendera kuti ishande zvakanyanya. Izvi zvinowedzera hupenyu hwebasa rechinhu chesefa uye zvinobatsira kudzikisira kuburitswa kwemagasi ekukuvadza anokuvadza mumhepo.

Exhaust gasi tembiricha sensors inoiswa pamberi uye mushure mekugadzirisa kuongorora kupisa kwayo uye kugona. Iyo yese SCS system inoongororwa uye inodzorwa nePCM kana inomira-yega mutyairi (iyo inobatana nePCM). Chero zvazvingaitika, mutungamiriri anotarisa iyo O2, NOx uye yekupedza gasi tembiricha maseru (pamwe nezvimwe zvigadzirwa) kuona nguva yakakodzera yeiyo jekiseni reEF. Precision DEF jekiseni inodiwa kuchengetedza iyo yekuzora gasi tembiricha mukati meyakagamuchirwa parameter uye kugadzirisa iyo filtration yezvinosvibisa.

Kana iyo PCM ikaona yakanyanyisa catalyst tembiricha (yechipiri mutsara weinjini), P200F kodhi inochengetwa uye irikusashanda chiratidzo mwenje inogona kuvhenekera.

Kucheka kweyakajairwa particule firita:

Chii chakakomba cheiyi DTC?

Chero ipi yakachengetwa catalytic system macode anogona kuve epamberi kune akavharika ekuzadza system. Iyo yakachengetwa P200F kodhi inofanirwa kurapwa seyakakomba uye inogadziriswa nekukurumidza sezvazvinogona. Kukuvadza kweCatalyst kunogona kuitika kana iwo mamiriro akakonzera kuenderera kwekodhi asina kugadziriswa nenzira yakakodzera.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP200F yekunetseka kodhi inogona kusanganisira:

• Yakaderedzwa injini kuita
• Hutsi hutema hwakawandisa kubva mumotokari chiutsi
• Yakadzikira mafuta kunyatsoshanda
• Mamwe makodhi ane chekuita nemweya

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi kodhi zvinogona kusanganisira:

• Yakaputsika SCR system
• Yakakanganisa SCR injector
• Isirizvo kana kukwana DEF fluid
• Yakaremara pedza gasi tembiricha sensor
• Yakashata SCR controller kana programming kukanganisa
• Kununura kunodonha pamberi pechigadziro
• Kuisirwa kweisiri-yepakutanga kana yepamusoro-inoshanda yezvinhu zveiyo chiutsi system

Ndeapi mamwe matanho ekutambudza iyo P200F?

Kana macCR macodhi akachengetwawo, anofanirwa kujekeswa vasati vaedza kuongorora iyo P200F yakachengetwa. Exhaust idonhedza pamberi pechigadziro chinoshandura chinofanira kugadziriswa usati waedza kuongorora iyi mhando yekodhi.

Kuti uongorore iyo P200F kodhi, iwe unozoda kuwana kune yekuongorora scanner, digital volt / ohmmeter (DVOM), infrared thermometer ine laser pointer, uye mota-yakatarwa yekuongorora ruzivo sosi.

Kana iwe uchikwanisa kuwana technical Service Bulletin (TSB) inoenderana negore rekugadzira, gadzira uye modhi yemota; pamwe neinjini yekufambisa, yakachengetwa kodhi / makodhi uye zviratidzo zvakawanikwa, inogona kupa ruzivo rwakakosha rwekuongorora.

Iwe unofanirwa kutanga kuongororwa kwako nekuona nekuongorora iyo SCR jekiseni system, pedza gasi tembiricha sensors, NOx sensors, uye oksijeni sensor harnesses uye zvinongedzo (02). Yatsva kana yakakuvara wiring uye / kana zvinongedzo zvinofanirwa kugadziriswa kana kutsiviwa usati waenderera.

Wobva wabatanidza iyo scanner kune iyo mota yekuongorora socket uye unotora ese akachengetwa makodhi uye inoenderana kuomesa furemu data. Nyora chinyorwa cheruzivo urwu usati wabvisa makodhi uye bvunzo kutyaira mota kusvikira iyo PCM yapinda yakagadzirira modhi kana kodhi yadzoswazve.

Iyo kodhi iri yepakati uye inogona kuve yakanyanya kuoma kuongorora (parizvino) kana PCM ikaenda yakagadzirira modhi. Muchiitiko ichi, mamiriro akakonzera kuchengetedzwa kwekodhi angangoda kuwedzera kusati kwanyatso kuongororwa.

Kana iyo kodhi ikatangazve, tsvaga yako mota ruzivo sosi yekuongorora ekuvharisa madhayagiramu, chinongedzo pinouts, chinongedzo kumeso kutarira, uye chikamu chekuyedza maitiro uye maratidziro. Iwe uchazoda ruzivo urwu kuti upedze nhanho inotevera mune yako kuongororwa.

Shandisa infrared thermometer kuona iyo chaiyo tembiricha pamberi uye mushure mekugadzirisa. Cherekedza iyo scanner dhata kuyerera kuti uenzanise yako chaiyo mhedzisiro neruzivo pane iyo scanner dhata inoratidza skrini. Zvakare enzanisa iyo data kubva kunopera gasi tembiricha sensors pakati pemitsara yeinjini. Kana pedza gasi tembiricha inopesana yawanikwa, tarisa ma sensors anoenderana uchishandisa iyo DVOM. Maseru asingasviki nemagadzirirwo emugadziri anofanirwa kutarisirwa kunge akaremara.

Kana ma sensors ese nematunhu ari kushanda nemazvo, fungidzira kuti chinhu chinobatsira chakakanganisika kana kuti iyo SCR system iri kunze kwehurongwa.

• Ita shuwa kuti DEF dura rakazadzwa neiyo chaiyo fluid uye iyo SCR system iri kushanda nemazvo.

Inoenderana DTC hurukuro

• Ikozvino hapana misoro inoenderana mumaforamu edu. Tumira chinyorwa chitsva paforum izvozvi.

Unoda rumwe rubatsiro neP200F kodhi?

Kana iwe uchiri kuda rubatsiro neiyo P200F kodhi, tumira mubvunzo mune zvakataurwa pazasi peichi chinyorwa.
