Iyo mudziyo uye musimboti wekushanda kweiyo camshaft chinzvimbo chinzwa

Injini dzemazuva ano dzine chimiro chakati omei uye dzinodzorwa neyakagadziriswa magetsi inoenderana nezviratidzo zve sensor. Senzwi yega yega inotarisa mamwe ma parameter ayo anoratidza mashandiro emota panguva ino, uye anotumira ruzivo kuECU. Muchikamu chino, tichakurukura chimwe chezvinhu zvakakosha zveinjini manejimendi system - iyo camshaft chinzvimbo sensor (DPRV).

Chii chinonzi DPRV

Pfupiso DPRV inomiririra camshaft chinzvimbo chinzwa. Mamwe mazita: Horo sensor, phase sensor kana CMP (Chirungu chidimbu). Kubva pazita iri pachena kuti iye anobatanidzwa mukushanda kwenzvimbo yekuparadzira gasi. Kunyanya chaizvo, pahwaro hwedata rayo, iyo system inoverenga yakakodzera nguva yejekiseni remafuta uye kuvesa.

Iyi sensor inoshandisa 5 volt reference voltage (simba) uye chikamu chayo chikuru iSensor sensor. Iye haateme nguva yejekiseni kana kuvesa, asi anongotumira ruzivo nezve iyo pfuti inosvika kune yekutanga TDC humburumbira. Kubva pane aya data, iyo jekiseni nguva uye nguva zvinotorwa.

Mune basa rayo, iyo DPRV inoshanda zvine chekuita ne crankshaft chinzvimbo sensor (DPKV), iri zvakare inoitisa iko iko iko kushanda kweye kuveza system. Kana nekuda kwechimwe chikonzero iyo camshaft sensor ikakundikana, iyo yakakosha data kubva kune crankshaft sensor inozotarisirwa. Iyo chiratidzo kubva kuDPKV chakanyanya kukosha mukushanda kweye kuveza uye jekiseni system, pasina iyo injini haingashande.

DPRV inoshandiswa pane ese enginjini dzemazuva ano, kusanganisira enjini dzemukati dzemoto dzine inochinja vharuvhu yenguva system. Iyo yakaiswa mumusoro we cylinder, zvinoenderana nemagadzirirwo emota.

Camshaft chinzvimbo sensor kifaa

Sezvambotaurwa, iyo sensor inoshanda pahwaro hweiyo Horo mhedzisiro. Mhedzisiro iyi yakawanikwa kumashure muzana ramakore rechiXNUMX nemumwe musayendisiti wezita rimwe chete. Iye akacherekedza kuti kana yakananga yazvino ikapfuura nepahwendefa rakatetepa uye ndokuiswa mumunda wekuita kwemagineti anogara aripo, ipapo mutsauko unogoneka unoumbwa kune mamwe magumo. Ndokunge, pasi pechiito chemagineti induction, chikamu chemasikironi chakatsauswa uye chinogadzira diki voltage kune mamwe mativi eplate (Horo yemagetsi). Inoshandiswa sechiratidzo.

Iyo DPRV yakarongedzwa nenzira imwecheteyo, asi chete mune fomu yepamusoro. Iine magineti anogara aripo uye semiconductor inosanganisirwa nhare ina. Iyo voltage yemagetsi inotumirwa kune diki diki rakabatanidzwa, kwarinogadziriswa, uye akajairwa mafoni (maviri kana matatu) ave kutobuda kunze kwemuviri weiyo sensor pachayo. Muviri wakagadzirwa nepurasitiki.

Ainoita

Iyo master disk (yekumhanyisa vhiri) yakaiswa pane camshaft yakatarisana neDPRV. Nekudaro, mazino akakosha kana fungidziro dzinoitwa pane camshaft master disk. Parizvino zviyero izvi zvichipfuura nemu sensor, iyo DPRV inogadzira chiratidzo chedhijitari yechimiro chakasarudzika, icho chinoratidza sitiroko yazvino mumasirinda.

Izvo zvakaringana kufunga nezvekushanda kweiyo camshaft sensor pamwe nekushanda kweDPKV. Maviri crankshaft revolutions account yeimwe camshaft shanduko. Ichi ndicho chakavanzika chekufananidza majekiseni uye masisitimu emagetsi. Mune mamwe mazwi, iyo DPRV uye DPKV inoratidza iyo nguva yekumanikidza sitiroko mune yekutanga humburumbira.

Iyo crankshaft master disk ine mazino makumi mashanu neshanu (58-60), ndiko kuti, kana chikamu chine buri remazino maviri chikapfuura neiyo crankshaft sensor, iyo system inotarisa chiratidzo neiyo DPRV uye DPKV uye inosarudza iyo jekiseni nguva muye yekutanga silinda . Mushure memazino makumi matatu, jekiseni rinoitika, semuenzaniso, mune yechitatu silinda, uyezve mune yechina neyechipiri. Aya ndiwo marongero anoitika. Ese aya ma signal ndiwo ma pulses anoverengwa neiyo control unit. Ivo vanogona kungoonekwa chete pane iyo oscillogram.

Kukanganisa zviratidzo

Izvo zvinofanirwa kutaurwa ipapo kuti neyakaremara camshaft sensor, injini ichaenderera ichishanda uye kutanga, asi nekumwe kunonoka.

Kusashanda kweDPRV kunogona kuratidzwa nezviratidzo zvinotevera:

• kuwedzerwa kunwa kwemafuta, nekuti iyo jekiseni haina kuwiriraniswa;
• mota inofamba nejeki, inorasikirwa nesimba;
• pane kurasikirwa kwesimba kunooneka, mota haigoni kumhanya nekumhanya;
• Injini haina kutanga pakarepo, asi kunonoka 2-3 masekonzi kana matanga;
• iyo kuvesa system inoshanda nezvakaipa, zvisirizvo;
• iyo-pabhodhi komputa inoratidza kukanganisa, iyo Injini Yekutarisa inovhenekera.

Zviratidzo izvi zvinogona kuratidza DPRV isiri kushanda, asi inogona zvakare kuratidza mamwe matambudziko. Izvo zvinodikanwa kuti uongororwe muhutano.

Pakati pezvikonzero zvekutadza kweDPRV zvinotevera:

• kusangana uye wiring matambudziko;
• panogona kunge paine chip kana kukotama pane protrusion ye master disk, nekudaro sensor inoverenga isiriyo data;
• kukanganisa kune sensor pachayo.

Nayo pachayo, ichi chidiki diki hachiwanzo kutadza.

Nzira dzeKuonesa

Kunge chero imwe sensheni inoenderana nemhedzisiro yeHoro, iyo DPRV haigone kuongororwa nekuyera iyo voltage kune vanobatana ne multimeter ("kuenderera"). Mufananidzo wakazara webasa rayo unogona chete kupihwa nekutarisa neiyo oscilloscope. Iyo oscillogram icharatidza pulses uye dips. Kuti uverenge data kubva kune oscillogram, iwe zvakare unofanirwa kuve neruzivo uye neruzivo. Izvi zvinogona kuitwa nenyanzvi inokwanisa panzvimbo yechiteshi kana munzvimbo yebasa.

Kana kukanganisika kukaonekwa, iyo sensor inoshandurwa kuita nyowani, hapana kugadzirisa kunopihwa.

DPRV inoita basa rakakosha mukuvesa uye jekiseni system. Kukanganisa kwayo kunotungamira kumatambudziko mukushanda kweinjini. Kana zviratidzo zvikawanikwa, zvirinani kuti uongororwe nenyanzvi dzinokwanisa.

Mibvunzo nemhinduro:

Гiripi camshaft position sensor? Izvo zvinoenderana nemuenzaniso wechikwata chemagetsi. Mune mamwe mamodheru, iri kurudyi, nepo mune mamwe iri kuruboshwe rwemota. Kazhinji inowanikwa pedyo nechepamusoro pebhanhire renguva kana kumashure kwemusoro.

Maitiro ekutarisa iyo camshaft chinzvimbo sensor? Iyo multimeter yakagadzirirwa kuyera DC ikozvino (yakakura 20 V). Iyo sensor chip yakabviswa. Simba riri mu chip pacharo rinotariswa (pamwe nekubatidza kuri). Voltage inoshandiswa kune sensor. Pakati pevanobatika panofanirwa kunge paine 90% yevoltage kubva kune yekupa chiratidzo. Chinhu chesimbi chinounzwa kune sensor - iyo voltage pa multimeter inofanira kudonha kusvika 0.4 V.

Chii chinoita camshaft sensor? Zvichienderana nemasaini kubva kune iyi sensor, iyo yekudzora unit inosarudza papi uye mune iyo cylinder inofanirwa kupa mafuta (vhura muromo wekuzadza humburumbira neBTC nyowani).
