Ndi mpweya wotani womwe OBD imazindikira mu utsi?

09.11.2022 /

Injini yanu imatha kuyaka - moto - womwe umapanga mpweya wotulutsa mpweya. Mipweya yamitundumitundu imapangidwa pakamagwira ntchito bwino ndipo iyenera kuyendetsedwa bwino chifukwa mipweya yambiri imakhala yowononga ikatulutsidwa mumlengalenga. Ndi malingaliro olakwika omwe anthu ambiri amawona kuti makina a on-board diagnostic (OBD) agalimoto yanu amazindikira mpweya, koma sizili choncho. Imazindikira zolakwika pazida zotulutsa mpweya (chosinthira chothandizira, masensa okosijeni, valavu yotsuka tanki yamafuta, etc.).

Masensa a oxygen

Zina mwazosokoneza pano zikugwirizana ndi chosinthira chothandizira komanso sensa ya okosijeni yagalimoto. Galimoto yanu ikhoza kukhala ndi chosinthira chimodzi kapena ziwiri zosinthira mphamvu ndi sensa imodzi kapena zingapo za okosijeni (zina zimakhala ndi masensa angapo a okosijeni omwe ali pamalo osiyanasiyana muutsi).

Chosinthira chothandizira chimakhala pafupifupi pakati pa chitoliro chotulutsa mpweya pamagalimoto ambiri (ngakhale izi zitha kusiyana). Ntchito yake ndikuwotcha ndikuwotcha mpweya wotuluka m'magalimoto onse. Komabe, dongosolo la OBD siliyesa mipweya imeneyi, kupatulapo mpweya.

Masensa a okosijeni (kapena masensa a O2) ali ndi udindo woyeza kuchuluka kwa okosijeni osapsa mu utsi wagalimoto yanu ndiyeno kutumiza chidziwitsocho ku kompyuta yagalimoto. Malingana ndi chidziwitso chochokera ku masensa a O2, makompyuta amatha kusintha kusakaniza kwa mpweya-mafuta kuti asayende mowonda kapena olemera (oxygen wochepa kwambiri kapena mpweya wochuluka, motsatira).

Zida zina zoyendetsedwa ndi dongosolo la OBD

Dongosolo la OBD limayang'anira magawo angapo osiyanasiyana okhudzana ndi mafuta / evaporation system, emission system, ndi machitidwe ena, kuphatikiza:

  • Vuto la EGR
  • Thermostat
  • chotenthetsera chothandizira
  • Kukakamiza crankcase mpweya wabwino
  • Zigawo zina za dongosolo la AC

Komabe, dongosolo la OBD siliyang'anira mpweya - limayang'anira magetsi ndi kukana, zomwe zingasonyeze vuto ndi zigawozi (ndipo chifukwa chake mpweya wonse wa galimotoyo).
