Ukushiswa kwe-DPF - kuyini ukuvuselelwa kwe-DPF? Sisebenza kanjani isihlungi se-particle? Iyini isihlungi se-DPF ne-FAP enjinini kadizili? Indlela yokushisa i-soot?

I-DPF particulate filter ingelinye lamadivayisi akhona ezimotweni zesimanje. Zonke izimoto zikadizili ezakhiwe ngemuva kuka-2000 zinayo. Namuhla, ziyanda izimoto ezisebenza ngophethiloli ezifakelwe i-DPF. Kuyafaneleka ukwazi ukuthi ungayinakekela kanjani ukuze umlotha osele kusihlungi ungaholeli ekulimaleni okukhulu. Thola ukuthi kuyini ukushiswa kwe-DPF!

Isihlungi se-Diesel Particulate - Siyini isihlungi se-DPF?

Isihlungi se-diesel particulate (DPF) sifakwe kusistimu yokukhipha umoya wezinjini zikadizili nezinjini zikaphethiloli. Umsebenzi wawo ukuhlanza amagesi e-exhaust ezinhlayiyeni eziqinile. Ahlanganisa ikakhulukazi ikhabhoni engashiswanga ngesimo sowothi. Kodwa-ke, ivame ukwaziwa ngezimoto ezifakwe injini ye-diesel. Konke sibonga izixazululo zemvelo kanye nokuhambisana nezindinganiso zaseYurophu emkhakheni wokunciphisa ukukhishwa kwezinhlayiya emkhathini. Isihlungi sezinhlayiya sibamba izinhlayiya zensimu eyingozi ngoba zinobuthi, zibangela umdlavuza futhi zibangela intuthu. Njengamanje, izindinganiso ze-Euro 6d-temp ziphoqa abakhiqizi ukuthi bafake izihlungi ze-diesel particulate ngisho nasezinjini zikaphethiloli.

Isihlungi se-DPF ne-FAP - umehluko

Isihlungi se-diesel particulate sibizwa ngokuthi i-DPF noma i-FAP filter. Naphezu komsebenzi ofanayo, ziyahlukahluka kumgomo wokusebenza. Esokuqala isihlungi esomile. Lokhu kusho ukuthi izinga lokushisa elifinyelela ku-700°C liyadingeka ukuze kushiswe umule oqoqiwe. Nakuba i-FAP iyisihlungi esimanzi. Ikhiqizwe yi-French concern PSA. Izinga lokushisa elingaba ngu-300 ° C lanele ukushisa umule. Kuyathakazelisa ukuthi lesi sixazululo singcono uma ushayela uzungeze idolobha, kodwa kuyabiza kakhulu ukusebenza. Ukusetshenziswa kwayo kuhlotshaniswa nesidingo sokugcwalisa uketshezi olukhuthaza ukuhlanzwa, ngakho-ke, ngezindleko ezengeziwe.

Isihlungi se-diesel particulate sivutha ngenkathi ushayela

Njengoba imayela lihamba, izinhlayiya eziningi ze-soot zihlala kusihlungi. Lokhu kungabangela izinkinga ngesihlungi se-diesel particulate futhi ngaleyo ndlela kuphazamise ukusebenza kwenjini kanye nokwandisa ukusetshenziswa kukaphethiloli. Kuyafaneleka ukusebenzisa izithasiselo zikaphethiloli, ukuqapha isimo soketshezi (uma kuyisihlungi esimanzi), ukushintsha uphethiloli wedizili njalo. Ngaphambi kokushintsha isihlungi, zama inqubo yokuvuselela i-DPF. Lokhu ungakwenza enkonzweni, esitobhini noma ngenkathi ushayela.

Inqubo yokushisa ye-DPF ngenkathi ushayela

Ukushayela udizili emzileni omude, njengomgwaqo, kuyindlela esebenzayo yokushisa isihlungi sezinhlayiya zedizili. Kulokhu, izinga lokushisa lamagesi aphumayo lingafinyelela izinga elanele ukuvuselela izihlungi zezinhlayiya. Kungalesi sizathu isihlungi sezinhlayiya sidala ukuphazamiseka kubashayeli basedolobheni. Kulokhu, isitayela sokushayela sibaluleke kakhulu, ngoba akukhuthazwa ukushayela ngesivinini esiphezulu uma injini ingafudumalanga kuze kufike ekushiseni okufunayo. Inqubo yokushisa isihlungi sezinhlayiya ngenkathi ushayela yisisombululo esilula nesingenankinga.

Ukushisa i-DPF endaweni

Isihlungi singahlanzwa futhi esimweni sokuma.. Uma ubona ukukhanya kukhanyisa, okubonisa isihlungi esivalekile, udinga ukusishisa ngaso leso sikhathi. Ukuze wenze lokhu, gcina isivinini senjini ku-2500-3500 rpm. Nokho, isisefo akumele sihlanzwe ezindaweni ezivalekile, amagaraji noma ezindaweni zokupaka izimoto ezingaphansi komhlaba.

Ukuhlanza isihlungi se-DPF kusevisi

Ungayishisa i-DPF ngaphansi kwezimo zokusebenza ngaphansi kokugadwa umakhenikha onolwazi. Lokhu kuyadingeka lapho imoto ingavamile ukushayela futhi udinga ukushisa i-soot kusuka kusihlungi. Ikhompyutha iqala inqubo eqala ngokufudumeza. Ngemva kokufinyelela izinga lokushisa, uphethiloli ujovwa ekamelweni elivuthayo. Imuncwa ku-exhaust system bese ingena kusihlungi se-DPF, lapho isha khona ngaphakathi kwesihlungi.

Sisebenza kanjani isihlungi se-DPF enjinini kadizili?

Umsebenzi oyinhloko wesihlungi se-diesel particulate ukumisa izinhlayiya eziphuma enjinini. Ngaphezu kwalokho, zishiswa ngaphakathi kwesisefo. Ngenxa yalokhu, inokuphila kwesevisi ende, futhi izinkinga eziningi zivela eqinisweni lokuthi isihlungi se-particle asishisi. Isihlungi ngokwaso siyidivayisi elula etholakala ohlelweni lwe-exhaust. Amashaneli aminyene ahlelwe ngokuhambisana amanye akha igridi. Avalwe ohlangothini olulodwa - ngokushintshana okokufaka noma okukhiphayo. Ngenxa yalokho, amagesi e-exhaust ashiya izinhlayiya ze-soot ezindongeni.

Ukutubeka kwe-DPF - ukwenze nini?

Ngokuvamile, i-diode kudeshibhodi ibonisa isidingo sokushisa isihlungi. Kodwa-ke, kufanelekile ukunaka izinguquko ekuziphatheni kwemoto. Isihlungi esivaliwe sizoholela ekulahlekelweni kwe-exhaust passage futhi, ngenxa yalokho, ukungenakwenzeka kokushisa imoto. Ngakho-ke kufanele unake izimpawu ezifana nalezi:

• ukwehla kwamandla ngesikhathi sokusheshisa;
• ukuphendula kancane ekucindezeleni i-pedal yegesi;
• amajika aguqukayo.

Isihlungi se-DPF siyadingeka ezimotweni zanamuhla, ngoba ngenxa yaso ungagwema ukukhishwa kwezinto eziyingozi emkhathini. Ngenxa yalesi sizathu, kuyadingeka, ikakhulukazi ezimotweni zikadizili. Ngokunakekelwa okufanele kwe-cartridge yokuhlunga, ungayisebenzisa ngaphandle kwezinkinga. Nokho, kufanele usebenzise imoto ngaphansi kwemithetho embalwa. Ngenxa yalokho, ungakwazi ukugwema isibopho sokushintsha isihlungi ufake esisha.
