Enkulumweni yanamuhla, sizokhuluma ngokusebenza kanye nokusebenza kwesihlungi se-Diesel Particulate Filter (DPF).Izihloko ezihlanganisiwe zifaka:
- Isakhiwo sangaphakathi se-DPF, ukusebenza nokusetshenziswa
- Ukuvuselelwa kwe-DPF ngokufundwa kwe-Oscilloscope
- Izimbangela Zokwehluleka kwe-DPF
Sawubona, Namuhla ngizokuhambisa ekwakhiweni nasekusebenzeni kwesihlungi sezinhlayiya zedizili.Izinsuku zentuthu emnyama engcolile ziya ngokuya zishabalala ngokushesha ngenxa yobuchwepheshe bokukhipha umoya kadizili obushintsha ngokuhamba kweminyaka, futhi imithetho eqinile yokukhipha umoya idinga ukuthi izinjini zikadizili zihlanzeke kakhulu.
Isihlungi se-diesel particulate esaziwa nangokuthi i-DPF,iyisihlungi esifakelwa ukukhipha amasistimu ezinjini zesimanje zikadizili. TAmadivayisi angafakwa ngaphambi noma ngemuva kwesiguquli se-catalytic.
Zidinga ukushisa ukuze zisebenze kahle. Tyakhe yingakho ezinye izihlungi ze-diesel particulate zifakwa ngqo ngemuva kwe-turbocharger.
Umklamo we-DPF uqukethe isihlungi sekhekhe lezinyosi i-monolith futhi simbozwe ngegobolondo lensimbi njengesiguquli se-catalytic esixhunywe kuyo..
Kuyinzwa yokucindezela okuhlukile enamapayipi afika afakwe endaweni yokungena futhi ukuphuma kwe-DPF kuzovala lokhu maduze.. Lezi izinto zokuhlunga eziyizinhlayiya ziza ngezinhlobonhlobo eziningi.
Lezi izinto zokuhlunga eziyizinhlayiyana ziza ngezinhlobonhlobo eziningi izinto ezisetshenziswa kakhulu ne-DPF izihlungi zokugeleza kodonga ze-cordierite noma izihlungi ze-silicon carbide wall flow..Ezinye izinto zokwakha zingabandakanya izihlungi ze-fiber yensimbi, i-fiber yensimbi igeleza ngezihlungi nezihlungi eziyingxenye.Izinjini zikadizili ezijwayelekile zikaloliwe ezifakelwe i-DPF zidinga uwoyela okhethekile ophansi womlotha.
Inhloso ye-DPF wukubambisa izinhlayiya ezidalwe yizo zonke izinjini zikadizili,ukuvimbela ukuba bangene emkhathini. Lezi zinhlayiya ziyingozi kakhulu ohlelweni lokuphefumula. Izinhlayiya zivaleleke ngamashaneli amancane angaphakathi kukadizilipveza isihlungi.Tizinhlayiya noma umule onamathela ezindongeni zamashaneli ngaphakathi kwe-DPF ushiswa njalo ngenqubo ebizwa ngokuthi ukuvuselelwa..
Ukwenziwa kabusha kuvimbela isihlungi se-diesel particulate ukuthi singavimbeli. Kunezinhlobo ezintathu zokuvuselela okuzenzakalelayo, okuguquguqukayo kanye nesevisi.Ukuvuselelwa okuzenzakalelayo okuguquguqukayo kanye nesevisi kwenzeka lapho i-DPF ifinyelela ku-600 degrees Celsius we-1112 degrees Fahrenheit uma ukuzalwa kabusha okuzenzakalelayo kungenzeki.,futhi i-ECU ibala ukuthi i-DPF isifinyelele umthamo wayo wesitoreji.
Ukuvuselelwa okuguquguqukayo kuqaliswa ukuvuselelwa okuguquguqukayo kuboniswa lapho ukukhanya kwe-DPF kukhanyisa iqoqo lezinsimbi.. Imoto kufanele iqhubeke nokuqedela ukukhiqiza kabusha kuze kucime ukukhanya. Uma ukuvuselelwa kabusha kwe-dynamic kuphazamiseka injini iyamiswa, it izoqaliswa kabusha emjikelezweni olandelayo wokusebenzisa injini uma ukuvuselelwa okuguquguqukayo kuqhubeka kuphazamiseka ngenxa yohambo olufushane olumbalwa.. Isibani se-DPF sizoqala ukukhanya.
Isexwayiso se-DPF esiguquguqukayo sizobonisa ukuthi ukuvuselelwa kwesevisi kufanele kwenziwe isevisi.Rama-e-generations kufanele agqugquzelwe kusetshenziswa ithuluzi lokuskena ngesikhathi sokuvuselelwa kwesevisi. EUphethiloli we-xtra ungengezwa kuphethiloli owengeziwe ungengezwa ngaphambili kwamapulse omjovo wokuthunyelwe. Lokhu kwandisa izinga lokushisa legesi ephumayo kudala amazinga okushisa ashisa kakhulu pf acishe abe ngu-600 degrees Celsius we-1112 degrees Fahrenheit. Ngakho-ke thina manje nezinhlayiya okufanele zishise uma isixwayiso se-DPF esikhanyayo singanakwa.
Ukunqwabelana kwensitha kungase kufinyelele ezingeni lapho ukufaka esikhundleni se-DPF kuwukuphela kwekhambi elingenzeka. Uma ukuvuselelwa kwesevisi kwenziwe ukufundwa kwenzwa yokucindezela okuhlukile kuzonquma ukuthi ukuvuselelwa kube ngempumelelo kangakanani.
Ungokuvamile ukuvuselelwa okunamandla kudinga ukulandelauhlobo lweukuvuselelwa kwesevisi ukwenza umjikelezo wokushayela ofanele. Uma ukuvuselelwa kungenakwenzeka,isihlungi se-diesel particulate kumele sishintshwe.
Amagesi akhipha umoya angalashiwe ashiya amasilinda amabili athwele izinhlayiya ku-DPF, ahlangana nezindonga zesiteshi esincane futhi umule uvaleleke..Icala lihlala ku-DPF kuze kuqalwe inqubo yokuvuselela.
Manje sizobheka amapharamitha wethuluzi lokuskena le-DPF, ngibheka idatha ngoba nginelambu le-DPF elishintshayo futhi ukuqoqwa kwe-soot kungaphezu kwamaphesenti ayikhulu..Ngizokwenza ukuvuselelwa kwesevisi futhi sizobheka iphethini yomjovo usebenzisa i-oscilloscope kulokhu kuvuselelwa kwesevisi yethuluzi lokuskena kutholakala kumenyu yemisebenzi ekhethekile.. Uma izimfuneko sezifinyelelwe ithuluzi lokuskena lizoqala ukukhiqiza kabusha.
Iphethini iqala ngemijovo emibili yomshayeli kanye nomjovo owodwa omkhulu lapho ama-rev enyuka, umjovo owodwa we-poly uyanyamalala iphethini yomjovo wokuthunyelwe iyavela.. Lokhu okokwenza i-DPF ifinyelele okungenani ku-600 degrees Celsius noma ku-1112 degrees Fahrenheit, ubude besikhathi buzohluka kuye ngezinga lokushisa le-DPF futhi lungase zinyamalale uma ukuvuselelwa kabusha iskuqediwe, iphethini evamile izovela futhi isimo esiqediwe sizovela ethuluzini lokuskena.
Lo mjikelezo uvela kaninginingi, ngenkathi ushayela ukugcina i-DPF ingavaleki ngezimpawu zezinhlayiyana ze-DPF ehlulekile kungaba amalambu ayisixwayiso kudeshi nokusebenza kabi kwenjini..
AI-DPF ingahluleka ngokuqhekeka kwezindlu phakathi nenqubo yakho yokuvuselela, uma umthamo wokugcina ugcwele kakhulu noma uwoyela kanye nokupholisa kungcolisa., tisihlungi esibangela ukuvala kwayo.Tisigqoko siwukwakhiwa nomsebenzi wesihlungi sezinhlayiyana zikadizili.
Kubaluleke kakhulu ukuqonda ukuthi i-DPF isebenza kanjani ukuze ikusize lapho uxilonga. Ngethemba ukuthi uzokuthola kuwusizo.Sobonana ngokuzayo.
