Mayelana ne-crankshaft sensor VAZ 2107

Ukusebenza kwenjini yomjovo kuncike ngqo engxenyeni efana nenzwa ye-crankshaft. Isebenzela ukuqinisekisa ukusebenza okuhambisanayo kwama-injector ngesistimu yokuthungela, ngakho-ke elinye igama layo inzwa yokuthungela kusengaphambili. Ku-VAZ 2107, inzwa ye-crankshaft ye-injector ingase ihluleke ngokuhamba kwesikhathi.

Inzwa ye-Crankshaft ku-VAZ 2107 - ukuklama nomgomo wokusebenza

Inzwa ye-crankshaft noma i-DPKV ku-VAZ 2107 iqinisekisa ukusebenza kwenjini (hhayi ezinzile, kodwa ngokujwayelekile). Ngayo, i-ECU iyazi ukuthi i-crankshaft ikusiphi isikhundla. Kusukela lapha, iyunithi yokulawula iyazi indawo yama-pistons kumasilinda, okuthinta ngokuqondile umjovo kaphethiloli ngokusebenzisa ama-nozzles kanye nokuvela kwenhlansi yokushisa imihlangano yamafutha.

Idivayisi ecatshangelwayo inomklamo olula. Izinzwa ezifakwe kuzo zonke eziyisikhombisa zisebenza ngomgomo we-inductance. Ingxenye iqukethe isisekelo sensimbi eyi-cylindrical, phezu kwayo lapho ucingo (ikhoyili) lilimele. Ingaphezulu lekhoyili limbozwe uzibuthe unomphela. Ukusebenza kwedivayisi kuhlotshaniswa negiya lendandatho, elixhunywe ku-crankshaft. Kungosizo lwaleli giya leringi lapho inzwa ithatha amasignali bese iwadlulisela kukhompyutha. Umgomo wokusebenza kwedivayisi umi kanje: lapho izinyo lomqhele lisezingeni lomgogodla wensimbi we-DPKV, amandla e-electromotive afakwa ekujikeni. I-voltage ivela ekugcineni kwe-winding, esethwe yi-ECU.

I-sprocket inamazinyo angama-58. Amazinyo amabili asusiwe esondweni, okudingekayo ukuze kunqunywe indawo yokuqala ye-crankshaft. Uma i-DPKV ihluleka, okuyinto eyivelakancane kakhulu, khona-ke ukuqala injini nokusebenza kwayo akunakwenzeka. Uhlobo lwenzwa, olufakwe ku-VAZ 2107, lunefomu elilandelayo: 2112-3847010-03/04.

Izimpawu zenzwa ephukile

Uphawu oluyinhloko lokuqhekeka kwe-DPKV ukungakwazi ukuqala injini. Ukwehluleka okunjalo kwenzeka ngenxa yokungasebenzi kahle kwedivayisi. Uma ingaphezulu le-DPKV lingcolile noma abathintwayo benziwe i-oxidized, ukungasebenzi kahle okulandelayo kungatholwa:

1. Ukuwohloka kokuguquguquka kwezimoto: ukushesha okubuthakathaka, ukuncipha kwamandla, ama-jerks lapho ushintsha amagiya.
2. Ama-turnovers aqala ukuntanta, futhi hhayi nje ngokungenzi lutho, kodwa futhi ngenkathi ushayela.
3. Khulisa ukusetshenziswa kukaphethiloli. Uma i-ECU ithola isignali ehlanekezelwe, lokhu kuthinta kabi ukusebenza kwama-injection.
4. Ukubonakala kokungqongqoza enjinini.

Uma izimpawu ezingenhla zitholakala, i-DPKV kufanele ihlolwe. Ukuze wenze lokhu, udinga ukwazi lapho inzwa crankshaft itholakala. Ku-VAZ 2107, i-DPKV itholakala kukhava yangaphambili yenjini, lapho ifakwe kubakaki. Kwamanye amamodeli ezimoto, le elementi ingase ibekwe ngakolunye uhlangothi lwe-crankshaft eduze ne-flywheel. Uma usola ukungasebenzi kahle kwe-DPKV, kufanele uyihlole.

Izindlela zokuhlola i-DPKV

Ungahlola ukufaneleka kwenzwa ye-crankshaft kuzo zonke eziyisikhombisa ngezindlela ezintathu ezahlukene. Okokuqala, kufanele kuqashelwe ngokushesha ukuthi ukungasebenzi kahle kwedivayisi kunganqunywa ngokubonakalayo. Ukuze wenze lokhu, hlola ingxenye, futhi phambi kokungcola, kanye nama-microcracks endlini yamagnet, umuntu angahlulela ukwehluleka kwayo. Ukungcola kususwa kalula, kodwa lapho kukhona ama-microcracks, ingxenye kufanele ishintshwe.

Inzwa ye-crankshaft ku-VAZ 2107 injector ihlolwe ngezindlela ezintathu:

1. Ukuhlola ukumelana. I-multimeter isethwe kumodi yokulinganisa ukumelana. Ama-probe athinta amatheminali edivayisi. Uma idivayisi ibonisa inani elisuka ku-550 kuya ku-750 ohms, khona-ke into ilungele ukusetshenziswa. Uma inani liphakeme noma liphansi kunokujwayelekile, khona-ke ingxenye kufanele ishintshwe.
2. Ihlola i-inductance. Xhuma i-LED noma i-multimeter iholela kumatheminali edivayisi. Ngesikhathi esifanayo, setha idivayisi kumodi yokulinganisa i-voltage ye-DC. Letha into yensimbi ekupheleni kwesiqephu bese uyisusa ngokushesha. Kulokhu, ukwanda kwe-voltage kufanele kwenzeke (i-LED izokhanya). Lokhu kubonisa ukuthi i-DPKV iyasebenza.
3. Ukuhlolwa kwe-Oscilloscope. Indlela enembe kakhulu nethembekile yokuhlola nge-oscilloscope. Ukuze wenze lokhu, i-DPKV ixhunywe kudivayisi, bese ingxenye yensimbi kufanele ilethwe kuyo. Isifunda sinquma ukusebenza okufanele kwe-DPKV.

Inzwa yokuma kwe-crankshaft eguquguqukayo esetshenziswa kweziyisikhombisa ikhiqiza ama-sinusoidal pulses. Zingena kukhompyutha, lapho zilungiswa khona zibe ama-pulses angunxande. Ngokusekelwe kulawa ma-pulses, iyunithi yokulawula inquma ukusebenzisa ukushaya kwenhliziyo kuma-injector nama-spark plugs ngesikhathi esifanele. Uma ngesikhathi sokuhlolwa kwavela ukuthi i-DPKV inephutha, kufanele ishintshwe.

Ungashintsha kanjani inzwa ye-crankshaft kwabayisikhombisa

Ukwazi lapho DPKV itholakala Vaz 2107, ngeke kube nzima ukuqaqa idivayisi. Le nqubo ayinzima futhi ayithathi isikhathi esiningi. Imiyalo enemininingwane yokuthi ungayishintsha kanjani inzwa ye-crankshaft ku-VAZ 2107 ibukeka kanje:

1. Umsebenzi wenziwa ngaphansi kwe-hood yemoto, kodwa futhi ungenziwa kusuka ngezansi.
2. Nqamula uthayi wekhebula ku-DPKV.
3. Usebenzisa i-screwdriver ye-Phillips, qaqa isiqeshana esivikela inzwa.
4. Susa idivayisi bese ufake entsha endaweni yayo. Umhlangano wenziwa ngokulandelana kwe-disassembly.

Ngemva kokufaka idivayisi, ungabheka ukusebenza kwenjini. Nakuba ingxenye ingavamile ukwehluleka, kunconywa ukuba njalo ube nenzwa eyisipele emshinini. Uma i-elementi ihluleka, ingashintshwa ngokushesha ukuze iqhubeke ihamba.

Ngenxa yalokho, kufanele kuqashelwe ukuthi i-DPKV iyinzwa ebaluleke kakhulu. Inomklamo olula futhi ayivamile ukuhluleka. Izindleko ezilinganiselwe zedivayisi yazo zonke eziyisikhombisa zingama-ruble angu-1000. Kunconywa ukuthi uhlole ingxenye hhayi kuphela ngezimpawu zokuqala zokungasebenzi kahle, kodwa futhi ngezikhathi ezithile uhlanze indawo yokusebenza ekungcoleni.
