Ungahlola kanjani inzwa ye-PMH?
Okuqukethwe
Ukuzwa Isikhungo esiphezulu esifile (TDC) yemoto yakho inquma indawo amavolovolo... Ibe idlulisela lolu lwazi ku-ECU yenjini, enganquma umjovo kaphethiloli odingekayo ngesivinini. Uma inzwa ye-TDC inesici, uzoba nayo izinkinga zokuqalisa... Nansi indlela yokuhlola inzwa ye-PMH.
Izinto:
- Ingena
- I-Chiffon
- Amathuluzi
- I-Voltmeter
- i-oscilloscope
- I-multimeter
🔎 Isinyathelo 1: Bheka ngokubuka inzwa ye-TDC.
Ukuze uhlole inzwa ye-TDC, kufanele uqale uyifinyelele. Inzwa ye-TDC, ebizwa nangokuthi i-crankshaft sensor, itholakala ku-crankshaft kanye ne-flywheel ezansi enjini. Khipha isikulufu sokugcina inzwa futhi unqamule ihhanisi phakathi kwenzwa ye-TDC ne-ECU yenjini.
Ake siqale ngokuhlola okubonakalayo okulula kwenzwa ye-TDC:
- Qinisekisa ukuthi ayivalekile;
- Qinisekisa ukuthi igebe lomoya alilimazi;
- Hlola ukuhlangana phakathi kwenzwa ye-TDC ne-ECU yenjini.
Ungathatha nethuba lokuhlola inzwa yakho ye-PMH usebenzisa ikhampasi. Iwuhlobo lokuhlola kokuqala okuncane, okungakutshela uma ngabe inzwa iyasebenza. Ngempela, inzwa ye-TDC eguquguqukayo inendawo kazibuthe ethola izinto zensimbi.
- Uma inzwa idonsela enyakatho, iyasebenza;
- Uma edweba eningizimu, ungu-HS!
Isexwayiso, lokhu kuhlola akusebenzi ngenzwa ye-PHM esebenzayo, eyaziwa nangokuthi i-Hall effect. Inzwa ye-TDC esebenzayo ayinayo insimu ye-electromagnetic ngoba i-electronic ngokuphelele. Itholakala, ikakhulukazi, ezinjini zakamuva.
💧 Isinyathelo sesi-2. Hlanza inzwa ye-TDC.
Ukuze isebenze ngokugcwele, inzwa ye-TDC akumele ingcoliswe. Nansi indlela yokuhlanza inzwa ye-TDC ngaphambi kokuyihlola:
- Fafaza i-WD 40 noma yimuphi omunye ugrisi emzimbeni wezinzwa;
- Sula ngobumnene ngendwangu ehlanzekile kuze kukhishwe konke ukungcola nokugqwala.
⚡ Isinyathelo sesi-3. Hlola isignali kagesi kanye nokumelana kwenzwa ye-TDC.
Bese uhlola isignali kagesi kanye nokumelana kwenzwa yakho ye-TDC. Nokho, qaphela uhlobo lwenzwa okukhulunywa ngayo: uma unenzwa ye-TDC esebenzayo, awunakho ukumelana nokuhlolwa. Ungahlola kuphela isignali kusukela kunzwa ye-TDC ye-Hall effect.
Sebenzisa i-ohmmeter noma i-multimeter ukuze uhlole inzwa ye-TDC engenisayo. Xhuma i-multimeter kokuphumayo kwenzwa ye-TDC bese uhlola inani elibonisiwe. Kuncike kumkhiqizi wemoto. Kunoma yikuphi, izoba phakathi kuka-250 no-1000 ohms. Uma kunguziro, kukhona isifunda esifushane endaweni ethile.
Bese uhlola isignali kagesi. Sebenzisa i-oscilloscope ukuze uhlole inzwa ye-TDC ye-Hall effect enezintambo ezi-3 (ezinhle, ezingezinhle nezesignali). Kuvele kungunxande. Ngenzwa ye-TDC esebenzayo, i-oscilloscope i-sinusoidal.
Hlola isignali yokuphumayo nge-voltmeter. Nqamula isixhumi senzwa ye-TDC bese uxhuma i-voltmeter ku-outlet ye-AC. Umphumela wenzwa enhle ye-TDC uphakathi kuka-250 mV no-1 Volt.
👨🔧 Isinyathelo 4. Qalisa ukuhlola ngogesi.
Kodwa-ke, indlela ethembeke kakhulu futhi enokwethenjelwa yokuhlola inzwa ye-TDC, ukuxilonga nge-elekthronikhi, ayitholakali kuwo wonke umuntu. Ngempela, lapho-ke kufanele ube necala lokuxilonga kanye nesoftware ehambisana nayo yokuxilonga. Nokho, leli thuluzi libiza kakhulu futhi ngokuvamile lingelamakhenikha angochwepheshe kuphela. Kodwa uma ungumakhenikha, akukho okukuvimbela ukuthi utshale imali.
Isofthiwe yokuxilonga ibuyisela ikhodi yephutha ebonisa uhlobo lwenkinga ngenzwa ye-TDC (isibonelo, akukho siginali). Ungaphinda usebenzise ukuxilonga ekuqaleni ukuze ubone, ngejika eligciniwe, ukusebenza kahle kwenzwa.
🔧 Isinyathelo sesi-5: Hlanganisa inzwa ye-TDC
Ngemva kokuhlola inzwa ye-TDC, kufanele uyihlanganise kabusha. Faka i-sensor flat, qinisa isikulufu sokulungisa. Xhuma kabusha ihhanisi lenzwa, bese uqala imoto ukuze uqiniseke ukuthi isebenza kahle.
Yilokho kuphela, uyazi ukuthi ungayihlola kanjani inzwa ye-PMH! Kodwa, njengoba usuqonda kakade, ukuhlolwa okungcono kakhulu kusengukuxilongwa kwe-electronic, amakhodi okuvumela ukuthi uthole ukuthi yini inkinga. Ukuze uhlole futhi buyisela inzwa ye-PMHngakho-ke qhathanisa amagaraji azungezile futhi uphathise imoto yakho kwabahle!
