Yadda ake bincika firikwensin PMH?
Abubuwa
Sensor Babban matattu cibiyar (TDC) na abin hawan ku yana ƙayyade matsayi pistons... Daga nan sai ta isar da wannan bayanin zuwa injin ECU, wanda zai iya tantance allurar man da ake buƙata don saurin gudu. Idan firikwensin TDC ba shi da lahani, za ku samu matsalolin farawa... Anan ga yadda ake bincika firikwensin PMH.
Kayan abu:
- Shiga
- Chiffon
- Kayan aiki
- Voltmeter

🔎 Mataki na 1: Duba firikwensin TDC da gani.
Don gwada firikwensin TDC, dole ne ka fara samun dama gare shi. Na'urar firikwensin TDC, wanda kuma ake kira firikwensin crankshaft, yana kan crankshaft da flywheel a kasan injin. Cire firikwensin riƙe dunƙule kuma cire haɗin kayan doki tsakanin firikwensin TDC da injin ECU.
Bari mu fara da sauƙin duban gani na firikwensin TDC:
- Tabbatar ba a toshe shi ba;
- Tabbatar cewa tazarar iska ba ta lalace ba;
- Bincika kayan aiki tsakanin TDC firikwensin da injin ECU.
Hakanan zaka iya amfani da damar don duba firikwensin PMH ta amfani da kamfas. Wani irin ɗan gwajin farko ne, zai iya gaya muku idan firikwensin yana aiki. Lallai, firikwensin TDC mai inductive yana da filin maganadisu wanda ke gano abubuwan ƙarfe.
- Idan firikwensin yana jan arewa, yana aiki;
- Idan ya zana kudu, HS ne!
Gargaɗi, wannan gwajin baya aiki tare da firikwensin PHM mai aiki, wanda kuma aka sani da tasirin Hall. Firikwensin TDC mai aiki ba shi da filin lantarki saboda gaba ɗaya na lantarki ne. Ana samo shi, musamman, akan injunan baya-bayan nan.
💧 Mataki na 2. Tsaftace firikwensin TDC.
Don cikakken aiki, dole ne firikwensin TDC ya gurɓata. Anan ga yadda ake tsaftace firikwensin TDC kafin a duba shi:
- Fesa WD 40 ko kowane maiko akan jikin firikwensin;
- A shafa a hankali tare da tsaftataccen zane har sai an cire duk datti da tsatsa.
⚡ Mataki na 3. Duba siginar lantarki da juriya na firikwensin TDC.
Sannan zaku duba siginar lantarki da juriya na firikwensin TDC ɗin ku. Koyaya, yi hankali da nau'in firikwensin da ake tambaya: idan kuna da firikwensin TDC mai aiki, ba ku da juriya don gwadawa. Kuna iya duba siginar kawai daga firikwensin TDC na tasirin Hall.
Yi amfani da ohmmeter ko multimeter don bincika firikwensin TDC mai kunnawa. Haɗa multimeter zuwa fitarwa na firikwensin TDC kuma duba ƙimar da aka nuna. Ya dogara da ƙera abin hawa. A kowane hali, zai kasance tsakanin 250 da 1000 ohms. Idan sifili ne, akwai gajeriyar kewayawa a wani wuri.
Sannan duba siginar lantarki. Yi amfani da oscilloscope don gwada firikwensin TDC na tasirin Hall wanda ke da wayoyi 3 (tabbatacce, korau da sigina). Ya zama rectangular. Don firikwensin TDC mai aiki, oscilloscope na sinusoidal ne.
Duba siginar fitarwa tare da voltmeter. Cire haɗin haɗin firikwensin TDC kuma haɗa na'urar voltmeter zuwa tashar AC. Sakamakon ingantaccen firikwensin TDC yana tsakanin 250 mV da 1 Volt.
👨🔧 Mataki na 4. Gudanar da bincike na lantarki.
Koyaya, hanya mafi aminci kuma abin dogaro don bincika firikwensin TDC, gwajin lantarki, ba ya samuwa ga kowa. Lalle ne, to ya kamata ku sami shari'ar bincike da software na autodiagnostic rakiyar. Duk da haka, wannan kayan aiki yana da tsada sosai kuma yawanci kawai na ƙwararrun makanikai ne kawai. Amma idan kai makanike ne, babu abin da zai hana ka saka hannun jari.
Software na bincike yana dawo da lambar kuskure wanda ke nuna yanayin matsalar tare da firikwensin TDC (misali, babu sigina). Hakanan zaka iya gudanar da bincike a farawa don lura, tare da kiyaye lankwasa, daidaitaccen aikin firikwensin.
🔧 Mataki na 5: Haɗa firikwensin TDC
Bayan duba firikwensin TDC, dole ne a sake haɗa shi. Shigar da firikwensin firikwensin, ƙara ƙara madaidaicin dunƙule. Sake haɗa na'urar firikwensin, sannan fara abin hawa don tabbatar da tana aiki da kyau.
Shi ke nan, kun san yadda ake gwada firikwensin PMH! Amma, kamar yadda kuka riga kuka fahimta, mafi kyawun gwajin har yanzu shine gwajin lantarki, lambobin waɗanda ke ba ku damar gano ainihin abin da matsalar take. Don dubawa kuma maye gurbin PMH firikwensindon haka kwatanta garejin da ke kusa da ku kuma ku amince da motar ku ga masu wadata!
