Uyibuyisela nini inzwa ye-PMH?

Inzwa ye-TDC iyingxenye ye-elekthronikhi yemoto yakho evumela injini yakho ukuthi iqale. Uma ingasasebenzi, kuzomele uye egaraji ukuze uyilungise ngokushesha. Uma unemibuzo mayelana nokusebenza nokugcinwa kwenzwa yakho ye-PMH, le ndatshana ingeyakho!

🚗 Iyini indima yenzwa ye-PMH?

Inzwa ye-TDC (noma i-Top Dead Center) iyingxenye kagesi ebizwa nangokuthi inzwa ye-crankshaft noma inzwa yesivinini. Itholakala ku-crankshaft kanye ne-flywheel.

Lokhu kuvumela isivinini senjini ukuba sibalwe futhi ngaleyo ndlela umjovo kaphethiloli ushintshwe.

Le nzwa inomsebenzi ombaxambili: yazisa ikhompyutha yokulawula injini mayelana nokuma kwepiston kanye nesivinini sokujikeleza kwe-crankshaft.

Okokugcina, siyaqaphela ukuthi le nzwa isetshenziswa kancane futhi kancane futhi iguqulelwe ezimotweni zesimanje; kancane kancane ithathelwa indawo amamodeli anomphumela weHholo.

🔍 Itholakala kuphi inzwa ye-TDC?

Inzwa ye-TDC, ebizwa nangokuthi i-crankshaft sensor, itholakala ezingeni le-flywheel yenjini. Lokhu kuvumela uphawu lwe-notch ku-flywheel yenjini futhi ngaleyo ndlela kuxhumane nendawo yawo wonke amaphistoni akha injini kukhompyutha.

.️ Inzwa ye-TDC ihlala isikhathi esingakanani?

Ukuphila kwenzwa ye-TDC kunzima ukunquma. Ayinakushintshwa impilo yonke yemoto, njengoba ingase ihluleke ngemva kwamashumi ezinkulungwane zamakhilomitha.

🚘 Ungahlola kanjani inzwa ye-TDC?

Nazi izimpawu ezikhombisa ukuthi inzwa ye-TDC isesimweni se-HS:

• Isiqalo esingenakwenzeka noma esinzima;
• Injini inyakaza futhi ingqongqoza;
• Izitolo eziningi ezifika ngesikhathi lapho ushayela ngesivinini esincishisiwe;
• I-tachometer ayisabonisi ulwazi olulungile.

Ngeshwa, ezimweni eziningi akunakwenzeka ukuqala injini ngenxa yokungasebenzi kahle kwenzwa ye-TDC. Le njini ayifuni ukuduma.

Lezi zimpawu ezifanayo zingabonisa ezinye izinkinga, ngakho cela umakhenikha ukuba ahlaziye imoto yakho ukuze ungafinyeleli esiphethweni.

🔧 Ngazi kanjani uma inzwa yami ye-TDC iyasebenza?

Ukuze uqiniseke ukuthi inzwa yakho ye-PMH isebenza kahle, uzodinga ukuhlola ukumelana kwayo nge-multimeter. Sichaza ukuthi kwenziwa kanjani lapha!

Izinto ezidingekayo: i-multimeter, i-wrench eguquguqukayo.

Isinyathelo 1. Hlukanisa inzwa ye-PMH

Okokuqala, kuzodingeka uhlukanise inzwa ye-PMH ukuze uyihlole. Ukuze uyiqaqe, qaqa izikulufu eziyibambe endaweni, bese unqamula inzwa kuzixhumi futhi uyikhiphe kukesi.

Isinyathelo sesi-2. Hlola inzwa ngokubuka

Okokuqala, bheka igeji yakho bese uthatha i-inventory ebonakalayo esheshayo. Qinisekisa ukuthi inzwa yakho ayivaleki kakhulu, bese uqinisekisa ukuthi i-harness ayinqunywa (ikakhulukazi, ingabangela i-circuit emfushane) nokuthi igebe lomoya alilimele. Uma konke kulungile, inkinga akuyona inzwa eyonakele, ngakho ungayibheka nge-multimeter.

Isinyathelo sesi-3. Hlola ubuqotho

Ukuze uhlole ukuqhubeka kwenzwa, faka i-multimeter kumodi yokuhlola ukuqhubeka. Lesi sinyathelo sizohlola umjikelezo omfushane phakathi komhlaba kanye nokuphuma kwenzwa. Qala ngokufaka ingxenye eyodwa ye-multimeter kwenye yezimbobo zetheminali futhi enye igcine phansi. Yenza okufanayo nakweminye imbobo. Uma i-multimeter ibonisa u-1, akukho ukuphumula. Ngakho akuyona inkinga leyo. Uzodinga ukuhlola ukumelana kwenzwa ye-pmh.

Isinyathelo sesi-4: hlola ukumelana

Ukuze uhlole ukumelana kwenzwa yakho, faka i-multimeter yakho kumodi ye-ohmmeter. Qala ngokuhlola lokho okubizwa ngokuthi "okuvamile" ukumelana kwenzwa ye-PMH kuwebhusayithi yomkhiqizi wezinzwa (okuvezwa ngama-ohms, isb 250 ohms). Bese ufaka iziphetho ezimbili ze-multimeter emigodini emzimbeni wezinzwa.

Uma, lapho kulinganiswa i-voltage, i-multimeter ibonisa inani elingaphansi kwenani elinconyiwe lomkhiqizi (lapha 250 Ohm), lokhu kungenxa yokuthi inzwa ye-PMH ayisebenzi futhi kufanele ishintshwe. Uma, ngakolunye uhlangothi, inani lilingana noma liphakeme kancane, kusho ukuthi inzwa yakho ye-PMH isesimweni esihle futhi inkinga ikwenye indawo. Ngakho-ke, sikweluleka ukuthi uye egaraji ukuze uthole ukuxilongwa okuphelele kwemoto yakho.

️ Kuthiwani uma inzwa yami ye-TDC ingasebenzi?

Uma inzwa yakho ye-TDC ihluleka, kufanele ishintshwe ngokushesha noma ngeke ukwazi ukubuyela emgwaqeni. Ukuze uthole intengo ehamba phambili, thola okunikezwayo ngokuchofoza oku-3 kwelinye lamagaraji ethu athembekile.

Inzwa ye-PMS HS ikhombisa ukuma ngempoqo kwemoto yakho. Ayikwazi ukuthumela ulwazi olulungile enjinini, ayikwazi ukuqala. Uma ufika kulokhu, kunesixazululo esisodwa kuphela: kwenze. buyisela.
