Indlela yokuxilonga inzwa ye-camshaft?

Zonke izimoto zanamuhla zifakwe ingxenye edingekayo njengenzwa ye-camshaft. Umsebenzi wayo oyinhloko ukunikeza umyalo ukuze uphethiloli ufakwe kumasilinda. Uma inzwa inephutha, kubalulekile ukucacisa imbangela yokwehluleka bese uyishintsha.

Ukusebenza kwe-DPRV (inzwa ye-camshaft position) incike kumbuso wokushisa. Ukushisa ngokweqile kuzoyibhubhisa. Inzwa ngeke isebenze uma izintambo edlulisa ngazo futhi yamukele isignali zingasebenzi.

Indima ebalulekile idlalwa ukukhubazeka noma ukungcoliswa kwenzwa ngokwayo. Futhi, ngaphansi kwezimo ezinzima, ukusebenza kwemoto (ukushayela ngaphandle komgwaqo, ukuthuthwa kwezimpahla), inzwa ingashintsha noma okubi nakakhulu, isifunda esifushane sizokwenzeka. Ukuze uqede ukuwohloka kwenzwa ngesikhathi esingafanele, yenza ukuxilonga kwayo.

Ukuxazulula inkinga nge-DPRV

Uma inkomba ye-Check Engine isivele ivuliwe kuphaneli (ingase ingakhanyi njalo, kodwa ivele ngezikhathi ezithile), udinga nje ukufunda ikhodi yokuhlukanisa usebenzisa idivayisi yokuxilonga. Uma ungenayo idivayisi enjalo futhi akunakwenzeka ukuyithenga, udinga ukuxhumana nochwepheshe.

Ngemva kokuthola ikhodi eqondile yokwahlukanisa nokuyisusa, sincoma ukuthi wenze isethi yokuhlola okulula. Ukuba khona kwekhodi eyodwa yokwehluleka kwe-DPRV ebhalwe ngenhla akusho ngaso sonke isikhathi ukuthi inzwa kufanele ishintshwe. Kwenzeka ukuthi umthombo wenkinga uyisici ku-wiring, isixhumi, njll. Kungenzeka ngempela ukulungisa izinkinga ezinjalo ngokwakho.

Kodwa ukuze uhlole ukusebenza kwenzwa ngokwayo, udinga ukwenza isethi yezenzo. Yiqiniso, isignali kunzima ukuyixilonga ngaphandle kwemishini ekhethekile. Kodwa ulwazi oluyisisekelo luzohlinzekwa ngokuxilongwa nge-multimeter.

Indlela yokuxilonga i-wiring yenzwa ye-camshaft?

Okokuqala, hlola ngokubukeka isimo sesixhumi senzwa nezintambo eziya kuso. Qiniseka ukuthi akukho ukungcola, uwoyela noma ukugqwala lapho okungadala ukuphazamiseka. Hlola izintambo zokulimala. Kwenzeka ukuthi izinkinga zidalwe izintambo eziphukile, othintana nabo abampofu noma amaphutha kungqimba lokuvikela okubangelwa ukuchayeka emazingeni okushisa aphakeme. Izintambo ze-DPRV akumele zihlangane nezintambo ezinamandla kakhulu zesistimu yokubasa.

Okulandelayo, siyayithatha, "uyazi" ukuxilonga inani le-alternating ne-direct current (AC ne-DC, ngokulandelana). Kodwa udinga ukuthola ulwazi kusengaphambili mayelana nokuthi lezi zinkomba kufanele zibe yini inzwa esetshenziswa emotweni yakho. Kwezinye izinzwa, izixhumi zenzelwe ukuthi ukwazi ukuxhuma izintambo ezengeziwe kuzo ukuze ufunde idatha nge-multimeter.

Uma lokhu kungenzeki, zama ukunqamula isixhumi se-RPF futhi uxhume izintambo zethusi ezincane kutheminali yesixhumi ngasinye. Okulandelayo, faka isixhumi endaweni ukuze izintambo ezimbili ziphume emzimbeni wayo.

Enye inketho ukubhoboza izintambo ngayinye ngenaliti noma iphini (qaphela ukuthi ungafinyeleli izintambo!). Ngemuva kokuxilongwa okunjalo, izindawo ezilimele zokufakelwa kufanele zihlanganiswe kahle nge-tape kagesi ukuze umswakama ungangeni ngaphakathi.

Ukuxilongwa kwenzwa yokuma ye-camshaft enezintambo ezimbili:

• Uma kusetshenziswa i-electromagnetic DPRV emotweni, faka i-multimeter kumodi ye-AC.
• Omunye umuntu kufanele avule umlilo ngokuvula ukhiye ekhikhini ngaphandle kokuvula injini.
• Kufanele kube ne-voltage kumjikelezo. Xhuma enye ye-probe ye-multimeter "emhlabathini" (ingxenye ngayinye yensimbi yenjini yangaphakathi yomlilo), bese uxhuma eyesibili ngokushintshana nezintambo zenzwa ye-camshaft. Ukungabikho kwamandla kuzo zonke izintambo kubonisa inkinga kuzintambo eziya kunzwa.
• Cela umuntu osemotweni aqale injini.
• Thinta i-multimeter probe eyodwa ocingweni olulodwa lwesixhumi se-DPRV, nowesibili uye kolunye. Amanani azovela esikrinini sedivayisi, okufanele iqhathaniswe nokufundwa kokusebenza okunikezwe emiyalweni yokusebenza yemoto. Njengomthetho, izinkomba esikrinini ziyahlukahluka phakathi kuka-0,3-1 volts.
• Ukungabikho kwesignali kubonisa ukuwohloka kwenzwa ye-camshaft.

Ungakhalisa kanjani inzwa ye-camshaft 3 izikhonkwane?

Ukuxilongwa kwe-DPRV enezintambo ezintathu:

1. Thola intambo yamandla, intambo yaphansi kanye nentambo yesignali (sebenzisa imanuwali yokulungisa), bese uhlola ubuqotho bezintambo eziya kunzwa. I-multimeter kufanele ishintshelwe kumodi ye-DC.
2. Omunye umuntu kufanele avule umlilo ngaphandle kokuqala injini evuthayo yangaphakathi.
3. Sixhuma i-probe emnyama ye-multimeter "emhlabathini" (noma iyiphi ingxenye yensimbi yenjini yangaphakathi yomlilo), kanye nobomvu ocingweni lwamandla we-DPRV. Imiphumela etholiwe kufanele iqhathaniswe nedatha evela emiyalweni yokusebenza.
4. Umsizi kufanele aqale i-ICE.
5. Thinta i-probe ebomvu ye-multimeter kuntambo yesiginali ye-DPRV, bese uxhuma i-probe emnyama ocingweni lwaphansi. Uma kwenzeka ukwehluleka kwenzwa, i-voltage izoba ngaphansi kunalokho okushiwo encwadini yokulungisa. Kwenzeka ukuthi i-multimeter ayibonisi lutho nhlobo, okubonisa ukwehluleka kwenzwa.
6. Khipha i-DPRV bese uhlonza isici ngokukhubazeka kwemishini noma ukungcola.

I-camshaft position sensor iyithuluzi elilula kodwa elibalulekile, ukusebenza kwalo okunquma ukusebenza kahle kwenjini yomlilo yangaphakathi. Ngakho-ke, uma izimpawu zokwehluleka kwazo zibonakala, kufanelekile ukwenza izinqubo zokuxilonga ezifanele ngokushesha ngangokunokwenzeka. Zilula, futhi ngisho nomnikazi wemoto ongenayo isipiliyoni angakwazi ukuzibamba.
