Diesel auto engine taro man injector bututun mai DLLA156SM139A 105025-1390 don Zexel allurar bututun ƙarfe

(1) Karanta kashe kuma kwatanta ƙarfin lantarki da tsawon lokacin bugun jini
Ana iya nuna siginar allurar ta amfani da oscilloscope.Don wannan dalili, haɗa layin ma'auni zuwa layin siginar, da ɗayan layin zuwa fil ɗin ƙasa mai dacewa.Tare da injin yana gudana, yana yiwuwa a karanta kashe wutar lantarki da lokacin bugun jini (lokacin buɗewa) daga tsarin siginar.Lokacin buɗe bawul ɗin maƙura, lokacin bugun bugun jini dole ne ya ƙaru yayin lokacin haɓakawa, kuma tare da saurin injuna akai-akai (kusan 3000 RPM) dole ne ya koma baya, ko a ƙasa, ƙimar mara amfani.Za'a iya kwatanta sakamakon kowane silinda da juna, kuma wannan na iya ba da alamar kurakurai, misali ƙarancin wutar lantarki.

(2) Auna matsin man fetur da kuma duba tsarin ci da shaye-shaye don zubewa
Sauran gwaje-gwaje masu mahimmanci suna auna matsi na man fetur, don gano wasu abubuwan da za su iya yin kuskure (famfon mai, tace mai, mai kula da matsa lamba), da kuma duba tsarin ci da shaye-shaye don ɗigogi, don hana sakamakon auna karya.Idan firikwensin yana da haɗin haɗin-pin-2, yana yiwuwa ya zama firikwensin inductive.A wannan yanayin, juriya na ciki, yuwuwar gajeriyar kewayawa zuwa firam, da siginar za'a iya ƙayyade.

Don yin wannan, cire haɗin toshe kuma duba juriya na ciki na firikwensin.Idan ƙimar juriya ta ciki ta kasance 200 zuwa 1,000 ohms (dangane da ƙimar tunani), firikwensin yana da kyau.Idan darajar ta kasance 0 ohms, akwai ɗan gajeren lokaci, kuma a cikin yanayin M Ohm akwai hutu.Ana yin gwajin ɗan gajeren da'ira zuwa firam ɗin ta amfani da ohmmeter daga fil ɗin haɗi zuwa ƙasan abin hawa.Ƙimar juriya dole ne ta karkata zuwa ga rashin iyaka.Gwajin ta amfani da oscilloscope dole ne ya haifar da siginar sinus na isasshen ƙarfi.A yanayin janareta na Hall, kawai ƙarfin sigina a cikin siginar siginar murabba'i da ƙarfin wutar lantarki ne kawai za a gwada.Wannan dole ne ya haifar da siginar raƙuman murabba'i dangane da saurin injin.Ya kamata mu maimaita a wannan lokacin cewa yin amfani da ohmmeter na iya lalata janareta na Hall.
