Chinachake Chimene Muyenera Kudziwa Zokhudza Air Flow Sensor

Tanthauzo

Mpweya wothamanga wa mpweya, womwe umadziwikanso kuti mita yothamanga mpweya, ndi imodzi mwa masensa ofunikira mu injini ya EFI.Amasintha kutuluka kwa mpweya wokokedwa kukhala chizindikiro chamagetsi ndikutumiza ku chipangizo chowongolera zamagetsi (ECU).Sensa yomwe imayesa kuyenda kwa mpweya kupita ku injini ngati imodzi mwazizindikiro zowunikira jekeseni wamafuta.

Mtundu

Pali mitundu yambiri ya masensa akuyenda kwa mpweya pamakina ojambulira mafuta oyendetsedwa ndimagetsi.Masensa amtundu wa mpweya amatha kugawidwa mumtundu wa tsamba (mapiko mbale), mtundu wapakati, mtundu wa ray yotentha, mtundu wa filimu yotentha, mtundu wa mpukutu wa Karman, ndi zina zotero.

Blademtundu (mbale ya mapikotype) kuyenda kwa mpweyasensa

1. Yesani mtengo wokana

Choyamba, zimitsani choyatsira lophimba, kusagwirizana chingwe mphamvu batire, ndiyeno kusagwirizana waya cholumikizira cha mapiko mtundu mpweya otaya kachipangizo.Gwiritsani ntchito multimeter kuti muyese kukana pakati pa ma terminals.Mtengo wotsutsa uyenera kukwaniritsa mtengo wokhazikika.Apo ayi, sensa ya mpweya imawonongeka ndipo iyenera kusinthidwa.

2. Yesani mtengo wamagetsi

Choyamba lowetsani cholumikizira cha cholumikizira cha mpweya wotuluka, kenaka tembenuzirani choyatsira ku giya "ON" ndikugwiritsa ntchito multimeter kuyeza voteji pakati pa VC ndi E2 terminals komanso pakati pa VS ndi E2.Zotsatira za kuyeza ziyenera kukwaniritsa mtengo wokhazikika.Ngati sichoncho, sensa ya mpweya imawonongeka ndipo iyenera kusinthidwa.

3. Kuyeza chizindikiro cha ntchito

Chotsani cholumikizira chojambulira, yambitsani injini, kapena gwiritsani ntchito choyambira chokha kuti muzungulire injini ndikugwiritsa ntchito ma multimeter kuyeza voteji pakati pa ma terminals a VS ndi E2.Mphamvu yamagetsi iyenera kuchepetsedwa pamene kutsegula kwa tsamba kumawonjezeka pang'onopang'ono.Ngati sichoncho, zikutanthauza mpweya.Flowmeter yawonongeka ndipo ikufunika kusinthidwa.

Mtundu wa mpukutu wa Karmanmpweya wotuluka sensor

1. Yesani mtengo wokana

Choyamba, zimitsani cholumikizira choyatsira, chotsani chingwe chamagetsi cha batri, kenako cholumikizira waya cha mita yoyendera mpweya.Gwiritsani ntchito ma multimeter kuti muyeze kukana pakati pa THA ndi E2 ma terminals a mpweya wotuluka.Mtengo woyezedwa uyenera kugwirizana ndi mtengo wokhazikika.Ngati sichoncho, mita yoyendetsa mpweya imawonongeka ndipo ikufunika kusinthidwa.

2. Yesani mtengo wamagetsi

Lumikizani cholumikizira cholumikizira mita ya air flow kaye, kenako tembenuzirani cholumikizira kuti chikhale "ON" ndikugwiritsa ntchito multimeter kuti muwone kuchuluka kwamagetsi pakati pa ma terminals omwe alembedwa patebulo.Iyenera kukwaniritsa zofunikira zamtengo wapatali.Apo ayi, mita yoyendetsa mpweya imawonongeka ndipo iyenera kusinthidwa.

3. Kuyeza chizindikiro cha ntchito

Lumikizani cholumikizira chojambulira, yambitsani injini kapena gwiritsani ntchito choyambira chokha kuyendetsa injiniyo, ndipo gwiritsani ntchito oscilloscope kuyeza kugunda kwapakati pa terminal ya E1 ndi terminal ya KS.Payenera kukhala mawonekedwe amtundu wa pulse waveform, apo ayi mpweya wotuluka wawonongeka ndipo uyenera kusinthidwa.

Zotenthafnyengomtundu wa air flow sensor

1. Zimitsani chosinthira choyatsira, chotsani cholumikizira cholumikizira mita ya mpweya, ndipo gwiritsani ntchito multimeter kuyeza kukana pakati pa 3terminal ndi poyambira galimoto.Iyenera kukhala 0Ω.

2. Sinthani choyatsira kuti "ON" ndikugwiritsa ntchito multimeter kuyeza voteji pakati pa ma terminal 2 ndi 3 a mita yoyendera mpweya.Iyenera kukhala mphamvu ya batri.Ngati palibe magetsi kapena kupotoka kowerengera kuli kwakukulu kwambiri, yang'anani dera.Yang'anani ngati magetsi pakati pa 4 ndi 3 terminals ayenera kukhala pafupi ndi 5V, mwinamwake zikutanthauza kuti pali vuto ndi chingwe pakati pa ECU ndi sensa ya mpweya kapena ECU.Ngati pali mphepo yosasunthika poyima, fufuzani kuti voteji ya pansi pa terminal #2 ili pafupi 14V, apo ayi zikutanthauza kuti dera lapakati pa mita yoyendetsa mpweya ndi cholumikizira pampu yamafuta ndi lolakwika.Mpweya wapakati pa #3 ndi #5 uyenera kukhala pafupifupi 1.4V pamene palibe katundu.Pamene liwiro la injini likuwonjezeka, voteji pamapeto onse awiri ayenera kupitiriza kukwera, ndipo mtengo wapatali ndi pafupifupi 2.5V, apo ayi mita yoyendetsa mpweya iyenera kusinthidwa.

3. Zimitsani chosinthira choyatsira ndikuchotsa mita yoyendera mpweya.Ngati palibe mphepo, voteji pakati pa ma terminal 3 ndi 5 ayenera kukhala pafupifupi 1.5V.Gwiritsani ntchito chowuzira kuti muwuze mphepo yozizirira polowera mita ya mpweya, ndiyeno pang'onopang'ono musunthire chowuzira kumbuyo.Pamene mtunda ukuwonjezeka, mtengo wamagetsi pakati pa ma terminal 3 ndi 5 uyenera kuchepa pang'onopang'ono, apo ayi mpweya uyenera kusinthidwa ndi kuwerengera.

Ndikukhulupirira kuti zambiri zomwe tidagawana nazo za sensa ya air flow zitha kuthandiza aliyense.Zokonda zilizonse, talandiridwa kuti mulumikizane ndi wopanga wathu wa VW Air Flow Sensor.
