Pakutanga, mhando dzeVAZ-2107 dzakagadzirwa ne carburetors, uye chete mukutanga kwema 2000, motokari dzakatanga kugadzirirwa nozzles ne electronic control unit (ECU). Izvi zvaida kuwedzera kuiswa kwezviridzwa zvekuyeresa zvezvinangwa zvakasiyana, kusanganisira throttle position sensor (TPDZ) yeVAZ-2107 injector).

Chii chinoita DPS?

Basa revhavha ye throttle nderekugadzirisa huwandu hwemhepo inopinda mumotokari yemafuta. Iyo yakawanda iyo "gasi" pedal inotsikirirwa, iyo yakakura gaka muvhavhavha yekupfuura (accelerator), uye, maererano naizvozvo, mafuta ari mumajekiseni anowedzerwa neokisijeni nesimba guru.

TPS inogadzirisa nzvimbo ye accelerator pedal, iyo "inoshumwa" neECU. Iyo block controller, kana iyo gap yakavhurwa ne75%, inochinja painjini yakazara yekuchenesa modhi. Kana iyo throttle valve yakavharwa, iyo ECU inoisa injini mune isina basa modhi - yakawedzera mweya inoyamwa mukati kuburikidza nevhavha yemhepo. Uyezve, huwandu hwemafuta hunopinda mumakamuri ekupisa ejini hunoenderana ne sensor. Kushanda kwakazara kweinjini kunoenderana nekushanda kwechikamu chidiki ichi.

Device

Throttle position midziyo VAZ-2107 ndeyemhando mbiri. Aya ma sensors ekubata (resistive) uye asiri-yekubata mhando. Rudzi rwekutanga rwechigadzirwa chinenge mechanical voltmeter. Iyo coaxial yekubatanidza negedhi rinotenderera inovimbisa kufamba kweiyo contactor parutivi rwesimbi yesimbi. Kubva pakuchinja kwekona yekutenderera kwe shaft, hunhu hwechizvino ichipfuura nemuchina pamwe netambo kubva kune yemagetsi control unit (ECU) yeinjini inoshanduka).

Resistive sensor circuit:

Mune yechipiri vhezheni yeasina-contact dhizaini, iyo ellipsoidal inogara magineti iri padyo zvakanyanya nepamberi pechiso che damper shaft. Kutenderera kwaro kunokonzera shanduko mune magineti flux yechishandiso iyo iyo yakabatanidzwa yedunhu inopindura (iyo Hall effect). Iyo yakavakirwa-mukati ndiro pakarepo inoisa kona yekutenderera kweiyo throttle shaft, sezvakataurwa neECU. Magnetoresistive zvishandiso zvinodhura kupfuura zvigadziriso zvemagetsi, asi zvakavimbika uye zvinogara.

TPS yakabatanidzwa dunhu:

Chigadzirwa chacho chakavharwa mubhokisi repurasitiki. Maburi maviri anogadzirwa pamusuwo wekusungirira nema screws. Iyo cylindrical protrusion kubva ku-throttle body inokodzera musocket yemudziyo. Iyo ECU cable terminal block iri mudivi rekubatanidza.

Kukanganisa

Zviratidzo zvekushaya simba zvinogona kuzviratidza nenzira dzakasiyana, asi zvinonyanya kukanganisa throttle mhinduro yejini.

Zviratidzo zvekusashanda kweTPS, zvichiratidza kuparara kwayo:

  • kuoma kutanga injini inotonhora;
  • isina kugadzikana idling kusvika pakumira kwakazara kwejini;
  • kumanikidza "gasi" kunokonzera kukanganisa mujini, inoteverwa nekuwedzera kwakasimba kwekukurumidza;
  • idling inoperekedzwa nekuwedzera kukurumidza;
  • kushandiswa kwemafuta kunowedzera zvisina musoro;
  • tembiricha geji rinowanzopinda munzvimbo dzvuku;
  • nguva nenguva chinyorwa "Check Engine" chinowanikwa pane dashboard.

Diagnostics

Zvose zviri pamusoro apa zviratidzo zvekusashanda kwe throttle position sensor zvinogona kusanganiswa nekukundikana kwemamwe ma sensor mukombuta. Kuti uone chaizvo kuparara kweTPS, unofanirwa kuiongorora.

Enderera seinotevera:

  1. Bvisa chivharo kubva kune sensor connector block.
  2. Iginition iripo asi injini haina kutanga.
  3. Iyo multimeter lever iri munzvimbo ye ohmmeter.
  4. Iyo probes inoyera voltage pakati peakanyanya kubatwa (iyo yepakati waya inotumira chiratidzo kune komputa). Iyo voltage inofanira kunge yakapoteredza 0,7V.
  5. Iyo accelerator pedal inotsikirirwa nzira yese pasi uye iyo multimeter inobviswa zvakare. Panguva ino magetsi anofanira kunge ari 4V.

Kana iyo multimeter ichiratidza maitiro akasiyana uye isingapindure zvachose, saka TPS haina kurongeka uye inoda kutsiviwa.

Kutsiva kweDPDZ

Izvo zvinofanirwa kucherechedzwa ipapo kuti kugadziriswa kweimwe spare part kunogona kungofunga resistive (mechanical) sensors, sezvo zvigadzirwa zvemagetsi hazvigone kugadziriswa. Kudzoreredza yakasakara yekubata track kumba kunonetsa uye zviri pachena kuti haina kukosha. Naizvozvo, kana paine kukundikana, sarudzo yakanakisa ndeyekuitsiva neTPS itsva.

Hazvina kuoma kutsiva mudziyo wakakuvadzwa neitsva yekumhanyisa sensor. Hushoma ruzivo nescrewdriver uye chiridzwa chekubatanidza chinodiwa.

Izvi zvinoitwa sezvizvi:

  • motokari inoiswa panzvimbo yakadzikama, ichisimudza handbrake lever;
  • bvisa iyo yakaipa terminal yebhatiri;
  • bvisa iyo wire terminal block kubva paTPS plug;
  • pukuta iyo sensor inokwira mapoinzi nerag;
  • sunungura zvigadziriso zvekugadzirisa nePhillips screwdriver uye bvisa counter;
  • isa mudziyo mutsva, simbisa screws uye isa bhuroko mu sensor yekubatanidza.

Nyanzvi dzinopa zano kutenga itsva throttle position sensor chete kubva kune vane branded vagadziri. Mukuedza kuchengetedza mari, vatyairi vanova vanyajambwa vevatengesi venhema dzakachipa. Nekuita izvi, vanopinda munjodzi yekuerekana vakanamira munzira kana "kuzungaira" vachitenderedza mugwagwa mukuru, vachirasa mafuta akawanda kuenda kuchiteshi chepeturu chiri pedyo.
