Isibani sesexwayiso se-DPF siyakhanya - manje sekwenzenjani? Indlela yokuhlanza isihlungi se-diesel particulate

Izimoto zikadizili sekunesikhathi eside zibhekwa njengeziyilungele kakhulu imvelo. Ukusetshenziswa kancane kukaphethiloli kanye nethuba lokusebenzisa ama-biofuels kwenza abashayeli bedizili babe nonembeza ohlanzekile. Kodwa-ke, i-self-igniter ibonise ukuthi iwumthombo oyingozi wezinto eziyingozi.

Umlotha , okuwumkhiqizo ongenakugwenywa wokushiswa kukadizili, kuyinkinga enkulu. Umhlabathi uyinsalela kaphethiloli oshile.

Ezimotweni ezindala zikadizili ngaphandle kokuhlunga kwegesi ephumayo, into eqinile idedelwa endaweni ezungezile. . Uma uhogeliwe, kuyingozi njengezinto ezibangela umdlavuza njenge-nicotine netiyela kagwayi. Ngakho-ke, abakhiqizi bezimoto sebebophekile ngokomthetho ukuhlomisa izimoto ezintsha zikadizili ngohlelo olusebenzayo lokuhlunga igesi ekhishwayo .

Umphumela ungowesikhashana

Ngokungafani nesiguquli se-catalytic ezimotweni zikaphethiloli, isihlungi sezinhlayiyana zedizili siyisihluthulelo ngokwengxenye. I-DPF yilokho igama layo elikushoyo: ihlunga izinhlayiya ze-soot kumagesi akhipha umoya. Kodwa kungakhathaliseki ukuthi isihlungi sikhulu kangakanani, ngesinye isikhathi asisakwazi ukugcina umthamo waso wokuhlunga. I-DPF iyazihlanza .

Umlotha ushiswa ube umlotha ngokukhuphula izinga lokushisa lamagesi aphumayo , okuholela ekwehleni kwevolumu esele kusihlungi. Kodwa-ke, inani elithile lomlotha lihlala kusihlungi njengensalela, futhi ngokuhamba kwesikhathi isihlungi sikadizili sigcwala umthamo.

Uhlelo lokuzihlanza seluphelile amandla ayo kanye neyunithi yokulawula injini ikhombisa iphutha, lapho ikhombisa ukukhanya kokulawula kudeshibhodi .

Lesi sexwayiso asinakuzitshwa. Uma i-DPF isivaleke ngokuphelele, kuba nobungozi bokulimala kwenjini. Ngaphambi kokuba lokhu kwenzeke, ukusebenza kwenjini kuyehla ngokusobala futhi nokusetshenziswa kukaphethiloli kuyanda.

Ukulungisa kuyadingeka ngokomthetho

Isihlungi se-diesel particulate esisebenza kahle siyadingeka ukuze kuphumelele ukuhlolwa. Uma isevisi yokuhlola ithola isihlungi esivalekile, ukukhishwa kwesitifiketi sokunakekela kuyonqatshwa. I-MOT nanoma iyiphi ibhodi yokulawula ngokuvamile incoma ukushintshwa kwesihlungi. Kuye ngemodeli yemoto, lokhu kungase kubize kakhulu. Isihlungi esisha kanye ukushintshwa kubiza ubuncane be-euro eyi-1100 (± £972) , futhi mhlawumbe nangaphezulu. Nokho, kukhona okunye .

Ukuhlanza esikhundleni sokuthenga isihlungi esisha

Kunezindlela ezifakazelwe neziqinisekisiwe zokuhlanza i-DPF ukuyigcina iyinhle njengentsha. Izici:

- ukuhlanza okuvuthayo
- hlambulula ukuhlanza

noma inhlanganisela yazo zombili izinqubo.

Ukuze kushiswe ngokuphelele i-DPF ehlakaziwe, ifakwa kuhhavini lapho ishiswa khona kuze kube yilapho wonke umule osele ushiswa phansi. . Khona-ke isihlungi sishaywa ngomoya ocindezelwe kuze kube yilapho wonke umlotha ukhishwa ngokuphelele.

Ukuhlanza empeleni kuwukuhlanza isihlungi ngesisombululo sokuhlanza ngamanzi. . Ngale nqubo, isihlungi siphinde sivalwe ezinhlangothini zombili, okudingekayo ekuhlanzeni okwanele kwe-DPF emlotheni. Umlotha unqwabelana eziteshini ezivaliwe. Uma isihlungi sihlanzwa ohlangothini olulodwa kuphela, umlotha uhlala endaweni, yini eyenza ukuhlanza okokuhlunga kungasebenzi .

Imikhiqizo enegama ayenele

Lena inkinga enkulu ngezixazululo zokuhlanza izihlungi zasekhaya. . Kukhona inala emakethe izixazululo eziyisimangaliso ezithembisa ukuhlanzwa okuphelele kwesihlungi sezinhlayiya. Ngeshwa, lo mjaho ujoyinwe izinkampani ezidumile , ezaziwa kakhulu ngama-lubricant azo amahle kakhulu.

Bonke bakhangisa izixazululo zokupompa embotsheni ecushiwe ye-lambda probe ukuze kuhlanzwe isihlungi. Njengoba kushiwo ngaphambili: ukuhlanzwa okuphelele kwesihlungi kudinga ukwelashwa nhlangothi zombili . Ngesikhathi sokufakwa, ukuhlanza ohlangothini olulodwa kuphela kungenzeka. Ngakho-ke, lezi zixazululo ezenziwe ekhaya azifaneleki ngokuphelele ukuhlanza izihlungi.

Inkinga inkulu kakhulu

Izindlela ezitholakalayo zisebenza kancane. Indlela yomjovo inenye inkinga: i-ejenti yokuhlanza, exutshwe nensimu nomlotha, ingakha ipulaki eliqinile . Kulokhu, ngisho nezindlela zokuhlanza ezinzima kakhulu, njenge-calcination ekushiseni ngaphezu kuka-1000 °C , ungasebenzi.

Ukulimala kwesihlungi mubi kakhulu kangangokuthi ukufaka i-elementi entsha esikhundleni saso ukuphela kwendlela yokuphuma, futhi lokhu kuyadabukisa. Ukuhlanza okuphrofeshinali ngokusebenza kahle okuqinisekisiwe kuyatholakala kusukela ku-£180 , okuyi-1/5 izindleko ze-DPF entsha eshibhe kakhulu .

Ukuzihlakaza konga imali

Ukuqaqa isihlungi sezinhlayiya akunzima kakhulu , futhi ungakwazi ukonga imali ngokuzenzela wena bese uyithumela kumnikezeli wakho wesevisi. Okubi kakhulu kungase kuphuke. i-lambda probe noma inzwa yokucindezela. Umhlinzeki wesevisi unikeza ukubhoboza nokulungisa imbobo enentambo njengesevisi eyengeziwe. Kuhlala ishibhile kunokuthenga isihlungi esisha se-particle.

Uma ususa isihlungi se-particle, hlola ngokucophelela yonke ipayipi yokukhipha. Isici sokuhlunga siyingxenye ebiza kakhulu yesistimu yokukhipha umoya. Kunoma yikuphi, lapho imoto iphakanyiswa, yisikhathi esihle sokushintsha zonke izingxenye zesistimu yokukhipha imfucumfucu egqwalile noma enesici.

Ukusebenzisa kabusha i-lambda probe kuyindaba yefilosofi. I-DPF elungisiwe ayidingi i-lambda probe entsha noma inzwa yokucindezela. . Kunoma yikuphi, esikhundleni sengxenye kuleli cala ngeke kube buhlungu futhi kuzobeka indawo entsha yokuqala kuwo wonke umhlangano.

Njalo ufuna isizathu

Imvamisa, impilo yesevisi yesihlungi sezinhlayiya iba 150 km ngaphansi kwezimo ezihlukahlukene zokushayela. Amabanga amade omgwaqo ongaphezu kwehora kufanele avele njalo. Uma ushayela udizili amabanga amafushane kuphela, injini kanye nezinga lokushisa elidingekayo le-DPF yokuzihlanza akufinyelelwa.
Uma i-DPF ivaleka ngokushesha, kungase kube imbangela yokonakala okukhulu kwenjini. Kulokhu, uwoyela wenjini ungena ekamelweni elivuthayo kanye nesihlungi sezinhlayiya. Izizathu zalokhu kungaba:

- ukungasebenzi kahle kwe-turbocharger
– Iphutha ekubekweni kwekhanda lebhlokhi yamasilinda
- uwoyela uphawu onesici
– piston izindandatho

Kunezinqubo zokuphenya la maphutha . Ngaphambi kokufaka isihlungi se-diesel particulate esisha noma esilungisiwe, hlola injini ukuze uthole lolu hlobo lomonakalo. Uma kungenjalo, ingxenye entsha izovaleka maduzane futhi nokulimala kwenjini kungase kube kubi kakhulu. Ukushintshwa kwesihlungi akusizi.
