Chii chinonzi sensor ye crankshaft yemotokari?
Chinongedzo checrankshaft (chinozivikanwawo sechinongedzo checrankshaft position) chinhu chikuru musystem yekudzora injini yemagetsi. Chinonyanya kushandiswa kuona nzvimbo yekutenderera (angle) yecrankshaft uye kumhanya kweinjini, uye wobva watumira ruzivo urwu panguva chaiyo kuinjini control unit (ECU) kuti inyatso dzora nguva yekupisa, nguva yekuisa mafuta, uye kutevedzana kwekupisa.
Mabasa makuru
Sarudza kona ye crankshaft: Sarudza nzvimbo chaiyo yepiston mu cylinder (senge pakati pepamusoro pe dead).
Tarisa kumhanya kweinjini: Verenga RPM (ma revolutions paminiti) ne frequency yekutenderera kwe crankshaft.
Batana ne sensor ye camshaft position: Pamwe chete, ziva mamiriro ekushanda kwe cylinder yega yega (senge compression stroke), uye zadzisa sequential fuel injection uye ignition.
Mhando dzakajairika uye misimboti yekushanda
Mhando yemagetsi-yemagetsi induction (mhando yemagnetic pulse)
Yakagadzirwa nemagineti inogara iripo, coil ye induction, uye dhisiki resignal rine mazino/rim.
Kana crankshaft ikatenderera, dhisiki rechiratidzo rinochinja simba remagineti, zvichigadzira chiratidzo chemagetsi chinochinjana mu coil.
Chimiro chacho chiri nyore uye chakavimbika, chinoshandiswa zvakanyanya mumhando dzekare uye mune dzimwe mota dzemazuva ano.
Rudzi rwemhedzisiro yehoro
Inoshandisa chinhu cheHall kuti inzwe shanduko mumunda wemagineti uye inoburitsa chiratidzo chekurova kwemoyo chesquare wave.
Inoda magetsi ekunze e5V uye ine simba rakasimba rekudzivirira kukanganiswa uye kunyatsoita zvinhu nemazvo.
Inowanikwa mumakambani akadai seGeneral Motors (GM), Chrysler, nezvimwewo.
Rudzi rwePhotoelectric
Yakagadzirwa ne LED, photodiode, uye dhisiki rechiratidzo rine maburi echiedza.
Kuchinjana kwechiedza/mumvuri kunogadzira zviratidzo zvekurova kwemoyo, izvo zvaishandiswa muNissan nedzimwe mhando.
Nekuda kwekukanganiswa nemafuta neguruva, zvakanyanya kubviswa.
Nzvimbo yekuisa
Kumberi kwecrankshaft (pedyo nebhandi pulley)
Kumashure kwe crankshaft (pedyo ne flywheel kana transmission housing)
Pakati pe crankshaft
Mumugovanisi (mumhando dzekare)
Zviratidzo zvekukundikana kwakajairika
Injini haigone kutanga
Kusagadzikana kusina basa, kukurumidza kusina simba
Chiedza chemotokari chakabatidzwa
Makodhi ezvikanganiso akachengetwa (akadai seP0335, P0336, nezvimwewo)
Nzira yekuona (muenzaniso: rudzi rwemagnetic-electric)
Kuongororwa kwekudzivirira: Kudzivirira kwe coil kunowanzova 125–250Ω (zvichienderana nemuenzaniso).
Kutarisa magetsi emagetsi: Paunotanga injini, shandisa multimeter kuyera terminal inobuda, iyo inofanira kunge iine voltage yeAC pulse ye0.2–2V.
Kutarisa gap: Mukana uri pakati pe signal disc ne sensor's magnetic head unowanzova 0.2–0.4mm.
Kana sensor ikakuvara, ECU haizokwanisi kuwana ruzivo rwakakosha rwenguva, zvichikonzera kutadza kushanda kwesystem yekuisa mafuta nekupisa, uye mota haizokwanisi kushanda.
Sensor yecrankshaft (inozivikanwawo se crankshaft position sensor) chinhu chikuru mu electronic control system yeinjini. Basa rayo guru nderekuona kona yecrankshaft, kumhanya kweinjini, uye nzvimbo yepakati yepiston, uye wozotumira ruzivo urwu muchimiro chechiratidzo chemagetsi kuinjini control unit (ECU) kuti inyatso dzora nguva yekupisa uye nguva yekuisa mafuta.
Basa guru
Sarudza nzvimbo ye crankshaft: Ziva kona ye crankshaft iripo.
Yera kumhanya kweinjini: Verenga kumhanya (RPM) nenhamba yemapulses panguva imwe neimwe.
Tsvaga nzvimbo yepiston top dead center: Ipa referensi yekupisa uye kupinza mafuta kwesilinda yega yega.
Batana ne sensor ye camshaft position: Pamwe chete, sarudza kuti ndeipi cylinder iri pamagumo e compression stroke, uye gadzira sequential ignition uye fuel injection.
Nheyo yekushanda (nekupatsanura mhando)
Sensor ye crankshaft ine mhando nhatu huru, uye misimboti yavo yekushanda ndeiyi inotevera:
Mhando yemagetsi-yemagetsi induction (mhando yemagnetic pulse)
Yakagadzirwa nemagineti inogara iripo, coil ye induction, uye dhisiki resignal rine mazino/rim.
Sezvo crankshaft ichitenderera, dhisiki rechiratidzo rinochinja simba remagineti, zvichikonzera shanduko mumunda wemagineti, uye zvichigadzira simba remagetsi rinoshanduka (sine wave signal) mucoil.
ECU inoshandura chiratidzo ichi kuita mapurose uye inoverenga kumhanya nenzvimbo.
Semuenzaniso: Mamodheru ekutanga eNissan neToyota aishandisa nzira iyi, uye dhisiki remasaini raiwanzova nemazino asina kurongeka ekubatanidza.
Rudzi rwemhedzisiro yeHall Chinhu cheHall chinoshandiswa kunzwa shanduko mumunda wemagineti.
Impeller (ine maburi nemaburi) inokonzereswa kuti itenderere necrankshaft. Kana notch yakabatana neHall element, simba remagineti rinopfuura nepakati uye rinoburitsa pulse yepamusoro-soro; kana banga rikaivhara, simba remagineti rinodarika uye rinoburitsa nhanho yakaderera.
Chinobuda chiratidzo chewave chesikweya, chinoda simba rekunze re5V uye chine simba rakasimba rekudzivirira kukanganiswa.
Optical
Inoumbwa nechiedza che LED, photodiode, uye dhisiki rechiratidzo rine gomba rechiedza.
Kana dhisiki rechiratidzo richitenderera, gomba rechiedza rinobvumira chiedza kupfuura uye rinochivhara, zvichiita kuti photodiode igadzire voltage yekurova kwemoyo.
Inogona kugadzira chiratidzo chekona che crankshaft chakanyatsojeka che 1°, asi inogona kusvibiswa nemafuta neguruva, uye inowanzoonekwa muzvivako zvekare zvekuparadzira.
Zviratidzo zvekukanganisa zvakajairika
Injini haigone kutanga kana kutanga nedambudziko
Simba risina kukwana, kudedera, kumira
Chiedza chekudzivirira chinobatidzwa (senge P0335, P0336, nezvimwewo, makodhi ekudzivirira ane chekuita nemasensa enzvimbo yecrankshaft)
Zvikonzero zvinowanzoonekwa: waya dzekare, masensa ane tsvina, nzvimbo isina kuchena zvakanaka (sekunge nzvimbo ine magnetic-electric inofanira kuva 0.2–0.4mm)
Nzvimbo yekuisa
Kumberi kwecrankshaft (pedyo nepulley)
Housing inobhururuka kana clutch
Kumberi kwe camshaft
Mukati memutengesi (mumhando dzekare)
Mamodheru mazhinji aripo iye zvino anoshandisa masensa emagetsi kana kuti eHall-type, sezvo maumbirwo awo akavimbika uye anochinjika. Rudzi rweoptical haruwanzo shandiswa mumainjini emazuva ano nekuda kwekunzwa kwaro zvakatipoteredza.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
