Camshaft chinzvimbo chinzwa

Injini dzemazuva ano dzine mudziyo wakaoma uye unodzorwa nemagetsi control unit yakavakirwa pane sensor masaini. Imwe neimwe sensor inotarisisa mamwe ma paramita anoratidza kushanda kweinjini panguva ino, uye inotumira ruzivo kumakombuta. Muchikamu chino, tichatarisa chimwe chezvinhu zvinonyanya kukosha zveinjini manejimendi system: iyo camshaft chinzvimbo sensor (DPRS).

Chii chinonzi DPRV

Iyo chidimbu DPRV inomirira Camshaft Position Sensor. Mamwe mazita: Horo sensor, chikamu kana CMP (kupfupisa muChirungu). Kubva pazita racho zvakajeka kuti anobatanidzwa mukushanda kwegasi rekugovera gasi. Kunyanya, zvichibva pane yayo data, iyo sisitimu inoverengera nguva dzakakodzera dzejekiseni remafuta uye kupisa.

Iyi sensor inoshandisa referensi (supply) voltage ye5 volts, uye chikamu chayo chikuru iHoro inonzwa chinhu. Iye pachake haatsanangure nguva yejekiseni kana kupisa, asi anongotumira ruzivo pamusoro penguva iyo piston inosvika kune yekutanga TDC yehumburumbira. Kubva pane idzi data, nguva uye nguva yejekiseni inoverengwa.

Mubasa rayo, iyo DPRV inoshanda yakabatana neiyo crankshaft chinzvimbo sensor (DPKV), iyo zvakare ine basa rekuita kwakaringana kushanda kweiyo ignition system. Kana nekuda kwechimwe chikonzero iyo camshaft sensor ikatadza, iyo data huru kubva ku crankshaft sensor ichaverengerwa. Chiratidzo kubva kuDPKV chinonyanya kukosha mukushanda kwekupisa uye jekiseni system; pasina iyo, injini haingoshande.

DPRV inoshandiswa mumainjini ese emazuva ano, kusanganisira injini dzinopisa dzemukati dzine inochinja nguva yevharuvhu. Yakaiswa mumusoro wecylinder, zvichienderana nekugadzirwa kweinjini.

Camshaft chinzvimbo sensor kifaa

Sezvatotaurwa, sensor inoshanda pahwaro hweHoro mhedzisiro. Mhedzisiro iyi yakawanikwa muzana remakore rechi19 nemusayendisiti wezita rimwe chete. Akacherechedza kuti kana yakananga ikozvino yakapfuura nepakati pendiro yakaonda yakaiswa mumunda wekuita kwemagineti isingagumi, ipapo mutsauko unogona kuitika unoumbwa kune mamwe magumo ayo. Kureva kuti, pasi pechiito chemagnetic induction, chikamu chema electrons chinodzingirwa uye chinoumba diki voltage (Hall voltage) pane zvimwe zviso zveplate. Inoshandiswa sechiratidzo.

DPRV yakarongedzwa nenzira imwecheteyo, chete yakanyanya kufambira mberi. Iine magineti asingagumi uye semiconductor iyo mapini mana akabatanidzwa. Iyo voltage yechiratidzo inodyiswa kune diki yakabatanidzwa dunhu, kwainogadziriswa, uye akajairwa mabatiro (maviri kana matatu) ari kutobuda kunze kweiyo sensor imba. Muviri wakagadzirwa nepurasitiki.

Ainoita

Dhisiki disk (dhiraivha vhiri) yakaiswa pane camshaft yakatarisana neDPRV. Zvakare, mazino akakosha kana maprotrusions anogadzirwa pane camshaft drive disk. Panguva iyo izvi zvinokanganisa zvinopfuura ne sensor, iyo DPRV inogadzira chiratidzo chedhijitari chechimiro chakakosha, ichiratidza iko zvino piston sitiroko mumasilinda.

Kushanda kwecamshaft sensor kunonyanya kutariswa pamwe chete nekushanda kweDPKV. Pamatenderedzwa maviri ega ega crankshaft, pane shanduko imwe chete yemugovera. Ichi ndicho chakavanzika chekufananidza jekiseni uye masystem ekupisa. Mune mamwe mazwi, DPRV neDPKV inoratidza nguva yekutsikirira sitiroko pane silinda yekutanga.

Iyo crankshaft drive disc ine mazino makumi mashanu nesere (58-60), ndiko kuti, kana chikamu chine gap remazino maviri chichipfuura nepa crankshaft sensor, sisitimu inofananidza chiratidzo neDPRV neDPKV uye inosarudza nguva yejekiseni pane silinda yekutanga. . Mushure memazino makumi matatu, inoiswa, somuenzaniso, muhumburumbira wechitatu, uyezve mune yechina neyechipiri. Aya ndiwo mashandiro anoita sync. Ese masaini aya mapurusi anoverengwa ne control unit. Vanogona kungoonekwa chete muchimiro chesaisai.

Kukanganisa zviratidzo

Zvinofanira kutaurwa pakarepo kuti nechakaipa camshaft sensor, injini icharamba ichimhanya uye kutanga, asi nekumwe kunonoka.

Zviratidzo zvinotevera zvinogona kuratidza kusashanda kweDPRV:

• kuwedzera kushandiswa kwemafuta, sezvo jekiseni system isina kuwiriraniswa;
• motokari inozununguka, inopera simba;
• pane kuoneka kurasikirwa kwesimba, motokari haigoni kukurumidza;
• injini haina kutanga pakarepo, asi nekunonoka kwemasekonzi 2-3 kana kumira;
• iyo ignition system inoshanda nekukanganisa, kukanganisa;
• iyo-pabhodhi komputa inoratidza kukanganisa, iyo Injini Yekutarisa inovhenekera.

Zviratidzo izvi zvinogona kuratidza kusashanda zvakanaka kweDPRV, asi zvinogona kuratidza mamwe matambudziko. Izvo zvinodikanwa kuita diagnostics mubasa kana kushandisa yakakosha diagnostic scanner. Somuenzaniso, Rokodil ScanX universal mudziyo.

Zvikanganiso P0340 - P0344, P0365 zvinoratidza kusashanda kana kuputsika mu wiring yeDPRV.

Pakati pezvikonzero zvekukundikana kweDPRV, zvinotevera zvinogona kusiyaniswa:

• matambudziko nekusangana uye wiring;
• iyo protrusion yedhisiki disk inogona kuputirwa kana kukotama, saka sensor inoverenga data isiriyo;
• kukanganisa kune sensor pachayo.

Nayo pachayo, kamudziyo kadiki aka kashoma kukundikana.

Nzira dzeKuonesa

Kufanana nechero imwe Hall effect sensor, iyo DPRV haigone kutariswa nekuyera voltage pane vanobatika ne multimeter ("kuenderera"). Mufananidzo wakazara webasa rako unogona kupihwa chete nekutarisa neoscilloscope. Pane oscillogram, pulses uye dip fronts zvichaonekwa. Kuverenga waveform data kunodawo ruzivo uye ruzivo. Izvi zvinogona kuitwa nenyanzvi inokwanisa pachiteshi chebasa kana nzvimbo yebasa.

Sensor zviratidzo zvinooneka zvakajeka pane oscillogram

Kana kusashanda kwakaonekwa, sensor inotsiviwa neimwe itsva, kugadzirisa hakupiwi.

DPRV inoita basa rakakosha mukupisa uye jekiseni system. Kukundikana kwayo kunotungamirira kumatambudziko mukushanda kwejini. Kana zviratidzo zvikaonekwa, zviri nani kuongororwa nenyanzvi dzinokwanisa.
