Air flow sensor, yomwe imadziwikanso kuti air flow meter, ndi imodzi mwama sensor ofunikira a injini yamagetsi yamagetsi yamagalimoto.Imatembenuza mpweya wotulutsa mpweya kukhala chizindikiro chamagetsi ndikutumiza ku gawo lolamulira lamagetsi (ECU).Monga chimodzi mwazizindikiro zodziwira jakisoni wamafuta, ndi sensor yomwe imayesa kutuluka kwa mpweya mu injini.VW air flow sensor sikuti ndi yotetezeka komanso yodalirika, komanso imakhala ndi ubwino wokhazikika, kusinthasintha komanso kukonza kosavuta.M'mawu amodzi, ndi kusankha bwino.
Mpweya wothamanga umagwiritsidwa ntchito poyeza mpweya womwe ukuyenda mu mpweya wa injini.Izi ndizofunikira pakuwerengera kuchuluka kwamafuta oti muwonjezere kuti mukwaniritse chiyerekezo choyenera chamafuta amafuta (AFR).AFR yabwino ndi 14.7: 1 (14.7 mapaundi a mpweya: 1.0 mapaundi a mafuta), koma AFR yeniyeni ndi yosiyana.Kuthamanga kungafunike AFR yokwera kwambiri mpaka 12:1, ndipo nthawi zina kuyenda panyanja kumatha kutsika mpaka 22:1.Ngati sensa ya MAF yawonongeka, gawo loyendetsa injini (ECM) silingathe kuwerengera jekeseni wa mafuta molondola, zomwe zingayambitse mavuto aakulu m'galimoto.

7 zizindikiro zoipaVW mpweya wotuluka sensor
Pali zizindikiro zingapo za kulephera kwa sensor ya MAF, koma sizizindikiro zonse zomwe zikuwonekera:
- Yang'anani ngati kuwala kwa injini kulipo: Mawonekedwe olakwika a machitidwe ndi mayendedwe ozungulira amatha kukhala ogwirizana mwachindunji ndi sensa ya MAF, koma kusintha kwamafuta ndi ma code misfire kumatha kulumikizidwanso ndi sensor ya MAF.
- Kuthamanga kolakwika: Ngati mukukumana ndi mavuto mukamathamanga mumsewu waukulu kapena magalimoto, zitha kukhala chifukwa cha vuto la sensor ya MAF, ndipo ECM ikhoza kuletsa jekeseni.
- Liwiro lopanda ntchito: Ngati palibe mafuta okwanira, zimakhala zovuta kupeza liwiro losalala lopanda ntchito.Ngati pali vuto ndi sensa ya MAF, injini sizingayende bwino, makamaka ikakhala idling.
- Kusauka kwamafuta amafuta: Sensa ya MAF siyenera kulephera kwathunthu kukhudza kuchuluka kwamafuta.Ngati ECM ili yolakwika, mafuta osafunikira amatha kuwonjezedwa, zomwe zimapangitsa kuti mafuta asamawonongeke.
- Utsi wakuda wakuda: Nthawi zina, ECM imatha kukhala yowuma kwambiri mpaka utsi wakuda umatuluka kuchokera ku utsi.Izi zithanso kudzaza chosinthira chothandizira.
- Kukayika kapena kuthamanga: Pakuthamanga kapena kuyenda panyanja, mutha kupeza kukayikira kapena mphamvu zadzidzidzi zachilendo, zomwe zingakhale zosokoneza.
- Zovuta kuyambitsa: Injini imafunikira mafuta ochulukirapo kuti iyambike kuposa kuyimitsa, koma ngati chizindikiro cha sensor ya MAF chapotozedwa, ECM singathe kulamula jekeseni wokwanira wamafuta kuti ayambitse injini nthawi yomweyo.
Mavutowa satanthauza nthawi zonse kuti sensor yanu ya MAF ndiyolakwika.Kutuluka kwa vacuum, zosefera za mpweya zotsekeka, utsi wocheperako, zosinthira zotsekera, kapena mapaipi olowera owonongeka atha kukhala chifukwa cha kusakwanira kwa sensor ya MAF, kotero chonde fufuzani kachitidwe kolowera kuti muthetse mavutowo kaye.
Momwe mungakonzere choyipaVW mpweya wotuluka sensor?
Ngati dongosolo lanu lotengera mpweya likuyenda bwino koma lili ndi zovuta, mutha kuyesa njira izi:
- Sansani fumbi.Limbani chitoliro cholowetsa mpweya ndikuyika fyuluta yatsopano ya mpweya kuti muteteze kulowerera kwa fumbi m'tsogolomu.
- Gwiritsani ntchito zotsukira.MAF sensor yotsuka yapadera imatha kuthana ndi kuipitsidwa kulikonse.
- M'malo mwake.Ngati masitepe awiriwa sakugwira ntchito, nthawi zambiri zimakhala zosavuta kusintha kachipangizo kakang'ono ka mpweya.
Kuzindikira zovuta zoyendetsa galimoto ndi njira yochotsera.Fananizani zida zagalimoto yanu ndi zidziwitso zodziwika bwino kuti muzindikire molondola komanso kukonza mwachangu.
Kusankha bwino VW air flow sensa kumatanthauza sitepe bwino kusankha galimoto yabwino, kotero muyenera kupeza odalirika ndi akatswiri VW mpweya otaya sensa fakitale.Yasen anatero.Ngati muli ndi chidwi ndi izi, mwalandilidwa kuti mutitumizire mtengo waulere.
