Nakhu ukuthi uhlanza kanjani isihlungi sakho se-particulate

Zonke izimoto zikadizili zesimanje nezikaphethiloli manje zinezihlungi zezinhlayiyana (kuphethiloli ibizwa ngokuthi i-catalyst). Ngokuya ngemodeli yemoto nesitayela sokushayela, izihlungi zesimanje zisebenza kusuka kumakhilomitha ayizinkulungwane eziyikhulu kuya kwezingama-100, futhi ngisho nangaphansi ngokushayela kaningi kwedolobha.

Ngokwenza lokhu, zimbozwa ngomsizi. Lapho kusha uphethiloli, izinsalela zama-hydrocarbon angashiswanga zingena epayipini lokukhipha, kwesinye isikhathi izinsimbi ezisindayo kanye nobunye ubuthi bungafakwa kulo mkhuba.

Hlunga idivayisi

Izihlungi ziqukethe isakhiwo se-ceramic esimise okwezinyosi esigcwele izinsimbi eziyigugu ezifana ne-platinum (efuthwe kahle kakhulu). Amaseli ahlangana nokuqongelela kwezinhlayiya, futhi nokuhlanza okuzenzakalelayo lapho ushayela emgwaqeni omkhulu ngesivinini esikhulu (izinga lokushisa ku-catalyst liyakhuphuka, kanye nomsizi ongavuthiwe oshisayo kushisa) kungenzeka kungakusizi.

Ukufakwa okunjalo kungaholela ekulahlekelweni kwamandla (ngenxa yokwanda okwandayo), noma kuvimbele nokuthi imoto iqale nhlobo.

Shintsha noma uhlanze?

Iningi labakhiqizi nabaphakeli beluleka ngokufakwa ngokuphelele kwe-DPF. Ngokuya ngensizakalo nemodeli yemoto, inani lingakhuphukela kuma-euro angama-4500. Isibonelo - isihlungi seMercedes C-Class sibiza ama-euro angama-600.

Noma kunjalo, ukufaka esikhundleni akudingekile ngaso sonke isikhathi. Imvamisa izihlungi ezindala zingahlanzwa ziphinde zisetshenziswe. Le sevisi ibiza cishe ama-euro angama-400. Noma kunjalo, akuzona zonke izindlela zokuhlanza ezinconywayo.

Izindlela zokuhlanza

Enye indlela yokuhlunga ukuhlunga izinhlayiya ngenkathi ushisa ingxenye kuhhavini. I-catalyst ifakwa kuhhavini elifudunyezwa kancane kancane lifike kuma-600 degrees Celsius bese lipholisa kancane. Uthuli nomlotha kuhlanzwa ngomoya ocindezelweyo neqhwa elomile (i-carbon dioxide eqinile, i-CO2)

Ngemuva kokuhlanza, isihlungi sithola cishe izakhiwo ezifanayo nezintsha. Kodwa-ke, le nqubo ithatha izinsuku ezinhlanu njengoba kufanele iphindwe kaningi. Intengo ifinyelela uhhafu wentengo yesihlungi esisha.

Okunye okuhlukile kule ndlela ukuhlanza okomile. Kuyo, ikhekhe lezinyosi lifuthwa ngoketshezi olukhethekile. Ihlasela kakhulu umule kepha ayisebenzi kakhulu uma kuqhathaniswa nezinye izimali ezifakiwe. Ngalesi sizathu, kusadingeka ukushaya umoya onomfutho, ongalimaza isakhiwo sezinyosi.

Ekuhlanzeni, isihlungi singathunyelwa enkampanini ekhethekile, futhi ukuhlanza kuthatha izinsuku ezimbalwa. Ngakho-ke, amaphesenti angama-95 kuya kwangu-98 okuhlunga angasetshenziswa kabusha. Le nqubo ingabiza kusuka kuma-euro angama-300 kuye kwangama-400.

Imibuzo nezimpendulo:

Ukuqonda kanjani ukuthi isihlungi se-particle sivalekile? Ngenxa yalokhu, kukhona isithonjana ku-tidy (injini), ukusetshenziswa kukaphethiloli kuzokwandiswa, ukudonsa kuzonyamalala (i-dynamics yemoto izokwehla), umusi ophumayo uzophuma epayipini lokuphuma, futhi injini izokhala ngesikhathi sokusebenza. .

Isihlungi sezinhlayiya sihlanzwa kanjani? Kwamanye amamodeli emoto, ukuvuselelwa okuzenzakalelayo kwesihlungi se-particulate kusetshenziswa. Lapho ivala, uphethiloli noma i-urea ifafazwa ku-matrix, evutha ngaphakathi kwesisefo, ikhiphe umule.

Kuthatha isikhathi esingakanani ukukhiqizwa kabusha kwesihlungi se-particle? Kuya ngokuthi imoto isetshenziswa kanjani. Isibonelo, ngaphansi kwezimo ezingasivumeli isihlungi ukuthi sifudumale sifike ezingeni oyifunayo, isilawuli sivula isifutho sikaphethiloli owengeziwe kusihlungi futhi sivale i-valve ye-EGR.
