Chithunzi cha mawaya a 3-waya crankshaft position sensor
Zamkatimu
M'nkhaniyi, muphunzira za XNUMX-waya crankshaft position sensor ndi mawonekedwe ake amawaya.
Ngati munayamba mwayikapo kapena kuyesa sensa ya 3-waya ya crankshaft nokha, mwina mukudziwa momwe zimachitikira. Kuzindikira mawaya a 3 sikukhala ntchito yophweka. Kumbali ina, muyenera kudziwa komwe mungawalumikize.
Sensa ya crankshaft ndi chida chofunikira chamagetsi chodziwira kuthamanga kwa injini ndi nthawi yoyatsira. Sensa ya crankshaft ya 3-waya imabwera ndi 5V kapena 12V reference, sigino, ndi mapini apansi.Mapini atatuwa amalumikizana ndi ECU yagalimoto.
"Zindikirani: Kutengera mtundu wagalimoto, cholumikizira cholumikizira cha crankshaft sensor chimasiyana."
Phunzirani zonse za 3-waya crankshaft masensa kuchokera m'nkhani ili pansipa.
Muyenera kudziwa china chake chokhudza crankshaft sensor
Ntchito zazikulu za sensor crankshaft ndikuzindikira kuthamanga kwa injini ndi nthawi yoyatsira. Sensa iyi ndi gawo lofunika kwambiri la injini za dizilo ndi mafuta.
Zindikirani. Kutengera mtundu wagalimoto, cholumikizira cholumikizira cha crankshaft sensor chimasiyana.
Mwachitsanzo, mitundu ina imabwera ndi 2-waya sensa ndipo ina imabwera ndi 3-waya sensa. Mulimonsemo, njira yogwirira ntchito ndi ndondomeko yolumikizira sizidzasiyana kwambiri.
Chidule mwamsanga: Sensor ya crankshaft ya 3-waya imatha kugawidwa ngati masensa a Hall effect. Zimaphatikizapo maginito, transistor, ndi zitsulo monga germanium.
Chithunzi chojambula cha 3-waya crankshaft sensor
Monga mukuwonera pachithunzi pamwambapa, sensor ya 3-waya crankshaft imabwera ndi mawaya atatu.
- Waya wolozera
- chizindikiro waya
- dziko lapansi
Mawaya onse atatu olumikizidwa ku ECU. Waya umodzi umayendetsedwa ndi ECU. Wayayu amadziwika kuti 5V (kapena 12V) voltage reference waya.
Waya wamagetsi amachoka ku sensa kupita ku ECU. Ndipo potsiriza, waya wapansi umachokera ku ECU, monganso waya wa 5V.
Reference voltage ndi ma signal voltage
Kuti mumvetse bwino kayendedwe ka magetsi, muyenera kukhala ndi chidziwitso chazomwe mumagwiritsa ntchito komanso ma voltages.
Mphamvu yamagetsi ndi mphamvu yomwe imachokera ku ECU kupita ku sensa. Nthawi zambiri, voteji iyi ndi 5 V, ndipo nthawi zina imatha kukhala 12 V.
Mphamvu yamagetsi ndi magetsi omwe amaperekedwa ku ECU kuchokera ku sensa.
Chidule mwamsanga: Kuyang'ana buku la eni galimoto yanu ndi njira yabwino yodziwira mtundu wa crankshaft sensor. Mwachitsanzo, bukuli lili ndi tsatanetsatane monga mtundu wa sensor ndi voltage.
Kodi 3-waya sensor imagwira ntchito bwanji?
Chinthu chikayandikira sensa, mphamvu ya maginito ya sensa imasintha, zomwe zimapangitsa kuti pakhale magetsi. Pomaliza, transistor imakulitsa mphamvu iyi ndikuitumiza ku kompyuta yomwe ili pa board.
Kusiyana pakati pa 2-waya ndi 3-waya masensa
Sensa ya 3-waya ili ndi zolumikizira zitatu ku ECU. Sensa yamawaya awiri imakhala ndi zolumikizira ziwiri zokha. Ili ndi ma siginecha ndi mawaya apansi, koma palibe waya wolozera pa sensa ya XNUMX-waya ya crankshaft. Waya wamakina amatumiza magetsi ku ECU, ndipo waya wapansi amamaliza kuzungulira.
Mitundu itatu ya crank sensors
Pali mitundu itatu ya masensa a crankshaft. Mu gawo ili, ndipereka kufotokoza mwachidule za iwo.
wochititsa chidwi
Ma pickups ochititsa chidwi amagwiritsa ntchito maginito kuti anyamule phokoso la injini. Masensa amtunduwu amayikidwa pa cylinder block ndipo mutha kuyimitsa sensor ya crankshaft pafupi ndi crankshaft kapena flywheel.
Masensa amtundu wa inductive safuna kufotokozera kwamagetsi; amapanga mphamvu zawozawo. Chifukwa chake, sensa yamawaya awiri ndi inductive-mtundu wa crankshaft sensor.
Chochita cha Hall
Masensa akuholo amakhala pamalo amodzi ngati masensa ochititsa chidwi. Komabe, masensa awa amafuna mphamvu zakunja kuti zigwire ntchito. Chifukwa chake, amaperekedwa ndi waya wowonetsa ma voltage. Monga ndanenera, voteji iyi ikhoza kukhala 5V kapena 12V. Masensa awa amapanga chizindikiro cha digito kuchokera ku siginecha ya AC yolandiridwa.
Chidule mwamsanga: Masensa atatu a crankshaft ndi amtundu wa Hall.
AC linanena bungwe masensa
Ma sensor a AC amasiyana pang'ono ndi ena. M'malo motumiza ma siginecha a digito monga momwe masensa a Hall amachitira, masensa okhala ndi zotulutsa za AC amatumiza siginecha yamagetsi ya AC. Masensa amtunduwu amagwiritsidwa ntchito kwambiri mu injini za Vauxhall EVOTEC.
Mafunso ofunsidwa kawirikawiri
Ndi mawaya angati omwe amalumikizidwa ku sensa ya malo a crankshaft?
Chiwerengero cha mawaya chikhoza kusiyana kutengera mtundu wagalimoto. Mwachitsanzo, magalimoto ena amabwera ndi masensa a mawaya awiri ndipo ena amabwera ndi masensa a mawaya atatu.
Monga mukumvetsetsa, sensa yamawaya awiri ili ndi mawaya awiri, ndipo sensa yamawaya atatu imakhala ndi mawaya atatu.
Chifukwa chiyani masensa atatu a crankshaft amafunikira ma voliyumu?
Masensa atatu a crankshaft amafunikira magetsi kuchokera kunja kuti apange voteji. Chifukwa chake, masensa awa amabwera ndi ma terminals atatu ndipo imodzi mwaiwo imayimira mphamvu yamagetsi. Ma terminals ena awiri ndi olumikizira ma siginecha ndi pansi.
Komabe, masensa a 2-waya crankshaft safuna kufotokozera kwamagetsi. Amapanga magetsi awoawo ndipo amawagwiritsa ntchito kuti apange magetsi owonetsera.
Kodi voteji 5V pa sensa iliyonse ya crankshaft?
Ayi, voliyumu yowunikira sikhala 5V nthawi iliyonse. Masensa ena a crankshaft amabwera ndi 12V.
Chifukwa chiyani kutchulidwa kwa 5V kuli kofala pamsika wamagalimoto?
Ngakhale mabatire agalimoto amaperekedwa pakati pa 12.3V ndi 12.6V, masensa amangogwiritsa ntchito 5V ngati mphamvu yawo yowunikira.
Chifukwa chiyani masensa sangathe kugwiritsa ntchito 12V yonse?
Chabwino, ndi zachinyengo pang'ono. Mwachitsanzo, mukamayendetsa galimoto, alternator imakankhira mkati ndikutulutsa magetsi ochulukirapo apakati pa 12.3 mpaka 12.6 volts.
Koma voteji yomwe imatuluka mu jenereta imakhala yosadziŵika kwambiri. Ikhoza kuzimitsa 12V ndipo nthawi zina imatha kutulutsa 11.5V. M'malo mwake, opanga amapanga masensa a 12V ndikukhazikitsa voteji ndi chowongolera magetsi.
Kodi mungayang'ane sensor yamalo a crankshaft?
Inde, mutha kuziwona. Mutha kugwiritsa ntchito digito multimeter pa izi. Yang'anani kukana kwa sensa ndikufananiza ndi mtengo wotsutsa mwadzina. Ngati mupeza kusiyana kwakukulu pakati pa zikhalidwe ziwirizi, sensa ya crankshaft sikugwira ntchito bwino.
Onani zina mwazolemba zathu pansipa.
- Chithunzi cha mawaya a ma 3-pin horn relay
- Kodi mawaya a spark plug amalumikizidwa ndi chiyani?
- Momwe mungalumikizire 2 amps ndi waya umodzi wamagetsi
