Njira Yotsamira Pamafuta Pambuyo pa Chothandizira, Bank 2

Kodi izi zikutanthauzanji?

Iyi ndi nambala yofalitsira yomwe imatanthawuza kuti imakhudza mitundu yonse kuyambira 1996 mpaka mtsogolo. Komabe, njira zina zothetsera mavuto zimatha kusiyanasiyana ndi galimoto.

Code P2098, PTC Fuel Trim System Too Lean in Bank 2, imangoyikidwa m'malo owonda (mpweya wambiri komanso mafuta osakwanira), omwe PCM yazindikira kuchokera kuzizindikiro za ma sensa a oxygen. Banki 2 ikuimira mbali ya injini yomwe ilibe yamphamvu # 1.

Masensa angapo a okosijeni mumayendedwe otulutsa nthawi zonse amawonetsa kuchuluka kwamafuta mu osakaniza. Dongosolo lililonse lotulutsa mpweya lomwe lili ndi chosinthira chothandizira lidzakhala ndi masensa awiri - imodzi pakati pa injini ndi chosinthira ndi imodzi pambuyo pa chosinthira.

Masensa a oxygen amawonetsa makina oyang'anira injini kuchuluka kwa mpweya womwe ulipo mu utsi, womwe umagwiritsidwa ntchito kudziwa ndikuwongolera kuchuluka kwamafuta. Mukakhala ndi mpweya wokwanira, mafuta amafunika kusakanikirana, ndipo mosakanikirana nawo amakhala olemera. Izi zimachitika mwazinthu zingapo zomwe zimatchedwa "kuwerengera". Pamapeto pa sensa ndi zirconium, yomwe imagwira mpweya mwanjira yoti, ikatentha, imadzipangira mavuto. Iyenera kukhala mozungulira 250 madigiri Fahrenheit kuti igwire ntchito ndikupanga mpaka ma volts 0.8.

Panthawi yogwira ntchito, sensa ya okosijeni idzazungulira kamodzi pa sekondi imodzi ndikupereka kompyuta ndi magetsi kuyambira 0.2 mpaka 0.8 kwa osakaniza olemera. Kusakaniza koyenera kudzakhala pafupifupi ma siginecha pafupifupi 0.45 volts. Cholinga cha mafuta ku chiŵerengero cha mpweya mu kompyuta ndi 14.7: 1. Sensa ya okosijeni siidzagwira ntchito pa kutentha kochepa monga kuyambika - pachifukwa ichi, masensa ambiri akutsogolo ali ndi preheater kuti achepetse nthawi yawo yotentha.

Masensa okosijeni ali ndi ntchito ziwiri - kuwonetsa mpweya wosawotchedwa mu utsi ndipo, chachiwiri, kuwonetsa thanzi la chosinthira chothandizira. Sensa yomwe ili kumbali ya injini imawonetsa kusakaniza komwe kumalowa mu chosinthira, ndipo sensor yakumbuyo imawonetsa kusakaniza komwe kumasiya chosinthira.

Pamene masensa ndi transducer akugwira ntchito mwachizolowezi, kauntala ya sensa yakutsogolo idzakhala yayikulupo kuposa yakumbuyo, kuwonetsa transducer yabwino. Masensa akutsogolo ndi kumbuyo akayenderana, chojambulira cha oxygen chakumaso ndicholakwika, chosinthira chatsekedwa, kapena chinthu china chikuyambitsa cholakwika cha sensor ya oxygen.

Khodi iyi ikhoza kuzindikirika kapena singawonekere pang'ono poyang'ana injini. Zimatengera chifukwa chake, komabe palibe chomwe chingalephereke mgalimoto osasokoneza china chake. Tsatirani vutoli ndikukonza nambala yanu posachedwa kuti mupewe kuwononga zinthu zina.

Zizindikiro

Zizindikiro za chikhombo cha P2098 zimasiyana kutengera kapangidwe kake kapena kachitidwe kake komwe kamawononga mafuta. Sikuti aliyense adzapezeke nthawi yomweyo.
