Mapepala a OBD-II DTC

Kuchita Bwino kwa NOx Pansi Pakuyandikira, Bank 1

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse za 1996 (Nissan, Honda, Infiniti, Ford, Dodge, Acura, Toyota, etc.). Ngakhale ndizachilengedwe, njira zowongolera zimatha kusiyanasiyana kutengera mtundu / mtundu.

P2000 yosungidwa imatanthauza kuti gawo loyendetsa mphamvu yamagetsi (PCM) lapeza mulingo wa nitrogen oxide (NOx) womwe uli pamwamba pa malire omwe adapangidwira. Bank 1 amatanthauza mbali ya injini yomwe ili ndi silinda nambala wani.

Injini yoyaka imatulutsa NOx ngati mpweya wotulutsa utsi. Makina osinthira othandizira, omwe amagwiritsidwa ntchito kuchepetsa mpweya wa NOx mu injini zamafuta, sagwira bwino ntchito mu injini za dizilo. Izi ndichifukwa cha kuchuluka kwa mpweya wabwino mumagetsi otulutsa ma injini a dizilo. Monga njira yachiwiri yopezera NOx mu injini za dizilo, msampha wa NOx kapena dongosolo la kutsatsa la NOx liyenera kugwiritsidwa ntchito. Magalimoto a dizilo amagwiritsa ntchito makina a Selective Catalytic Reduction (SCR), omwe msampha wa NOx ndiwonso.

Zeolite imagwiritsidwa ntchito kutchera ma molekyulu a NOx kuti atetezedwe kuti asatulukire mumlengalenga. Tsamba la zeolite limakhala mkati mwa nyumba yomwe imawoneka ngati chosinthira chothandizira. Mpweya wotulutsa mpweya umadutsa pa chinsalu ndipo NOx amakhalabe mkati.

Pofuna kukonzanso kapangidwe ka zeolite, mankhwala oyaka kapena oyaka moto amabayidwa kudzera mu jakisoni woyang'anira zamagetsi. Mankhwala osiyanasiyana agwiritsidwa ntchito pazinthu izi, koma dizilo ndiwothandiza kwambiri.

Mu SCR, masensa a NOx amagwiritsidwa ntchito chimodzimodzi ndi masensa a oxygen m'magetsi a mafuta, koma samakhudza njira yosinthira mafuta. Amayang'anira tinthu ta NOx m'malo mwa mpweya. PCM imayang'anira zambiri kuchokera pama sensa a NOx isanachitike komanso itatha chothandizira kuwerengera kuyambiranso kwa NOx. Izi zimagwiritsidwanso ntchito pamalingaliro operekera madzi NOx ochepetsa.

Wothandizira kuchepetsa amabayidwa pogwiritsa ntchito jakisoni yemwe amayang'aniridwa ndi PCM kapena gawo la SCR. Dambo lakutali lili ndi madzi NOX ochepetsa / dizilo; ikufanana ndi thanki yaying'ono yamafuta. Kupanikizika kocheperako kumapangidwa ndi pampu yamafuta yoyendetsedwa zamagetsi.

PCM ikazindikira mulingo wa NOx wopitilira malire omwe adakonzedweratu, nambala ya P2000 idzasungidwa ndipo nyali yosonyeza kuwonongeka itha kuwunikira.

Zizindikiro

Zizindikiro za chikhombo cha P2000 zitha kuphatikizira izi:

• Utsi wochuluka wochokera ku utsi wa injini
• Kuchepetsa magwiridwe antchito amtundu wonse
• Kuchuluka kwa kutentha kwa injini
• Kuchepetsa mafuta

zifukwa

Zomwe zingayambitse kachidindo kameneka ndi monga:

• Woperewera kapena wochulukirapo msampha wa NOx kapena chinthu cha NOx
• Opunduka dizilo utsi madzimadzi dongosolo jekeseni
• Nox wosayenera kapena wosayenera wochepetsera madzi
• Operewera utsi dongosolo mpweya recirculation
• Kutulutsa kwakukulu kwamafuta kutayikira kutsogolo kwa msampha wa NOx

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Kuti mupeze nambala ya P2000, mudzafunika chojambulira cha matenda, digito volt / ohmmeter (DVOM), ndi gwero lazidziwitso zamagalimoto monga All Data (DIY).

Ndikuyamba ndikuwona zowonera zonse zolumikizira ndi zolumikizira m'dongosolo. Muziganizira Kulumikizana pafupi zigawo zikuluzikulu za utsi otentha ndi zishango lakuthwa utsi.

Onetsetsani dongosolo la utsi kuti lichepetse ndikukonzekera ngati kuli kofunikira.

Onetsetsani kuti thanki ya SCR ili ndi zocheperako ndipo ndiyabwino. Tsatirani malingaliro a wopanga mukamawonjezera kuchepetsa madzi.

Onaninso momwe makina ogwiritsira ntchito mpweya amatayirira (EGR) akugwiritsira ntchito. Bweretsani ma code onse a EGR musanayese kudziwa nambala iyi.

Fufuzani ma DTC onse osungidwa ndikuimitsa data ya chimango polumikiza sikani ku doko lodziwira zagalimoto. Lembani izi; izi zitha kukhala zothandiza kupeza kachidindo kakanthawi. Chotsani ma code pamakina ndikuyamba injini. Ndimalola kuti injini ifike kutentha kwanthawi zonse ndikuyesa kuyendetsa galimoto kuti ndiwone ngati nambala yachotsedwayo.

Ngati yasintha, tsegulani sikani ndikuwona zidziwitso za NOX. Chepetsani kusanja kwanu kuti mukhale ndi zofunikira zokha ndipo mupeza zambiri zolondola.

Ngati masensa ena a NOx sakugwira ntchito, fufuzani fuseti yolowetsedwa mu chipinda cha injini kapena pansi pa bolodi. Masensa ambiri a NOx amapangidwa ndi waya wa 4 wokhala ndi waya wamagetsi, waya wapansi ndi zingwe zamagetsi ziwiri. Gwiritsani ntchito DVOM ndi bukhu lautumiki (kapena deta yonse) kuti muwone ma batri amagetsi ndi zizindikilo zapansi. Chongani kachipangizo kachizindikiro chizindikiro pa injini pa kutentha yachibadwa ntchito ndi liwiro ulesi.

Zowonjezera zowonjezera:

• Kusankha kolakwika kapena kusowa kwamadzi oletsa kukalamba ndiye chifukwa chofala kwambiri kuti code ya P2000 isungidwe.
• Kuchotsa valavu ya EGR nthawi zambiri kumakhala chifukwa chosagwira ntchito kwa msampha wa NOx.
• Mkulu magwiridwe antchito aftermarket utsi dongosolo zigawo zikuluzikulu kungathenso P2000 yosungirako

Mukufuna thandizo lina ndi code P2000?

Ngati mukufunabe thandizo ndi DTC P2000, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
