Kungani ama-Three-way Catalytic Converter engabizi amadola amathathu?

Siyazi ukuthi iziguquli zezindlela ezintathu ze-catalytic ngokuvamile ziqala kusukela ekuhlulekeni kwemoto.Akushibhile ukushintsha entsha ngama-yuan angamakhulu ambalwa noma ngaphezulu kwamayuan ayizinkulungwane eziyishumi. Kungani singakhulumi nge-catalyst yezindlela ezintathu namuhla? Kungani kubiza? Ungayisebenzisa kanjani imali encane futhi ushintshe kabi kancane?

Ekwenzayo

Singacabanga ngesiguquli sezindlela ezintathu se-catalytic kalula nje “njengesisetshenziswa sokuvikela imvelo” emotweni. Eminyakeni yamuva nje, ukungcoliswa komoya bekulokhu kuqashelwa ngokwandayo, futhi amazinga e-China aphuma emazweni ayisithupha abe phezulu. Iziguquli zezindlela ezintathu ze-catalytic sezibaluleke nakakhulu-ngamafuphi, zihogela amagesi ayingozi futhi zikhipha ezingenangozi. I-ejenti yokuhlanza ku-catalyst yezindlela ezintathu izothuthukisa umsebenzi we-CO, i-HC ne-NOx kugesi yokukhipha imoto, okubangela ukuthi iqhubeke ne-redox ethile futhi ekugcineni ibe igesi engenangozi.

Kungani Kubiza

Abantu abashintshile bayazi ukuthi iziguquli zezindlela ezintathu ze-catalytic zibiza ngempela. Ezinye izimoto zibiza amashumi ezinkulungwane zama-yuan, okungaba ingxenye eyodwa kweshumi yezindleko zemoto. Kunezizathu ezimbili eziyinhloko zokuthi kungani ibiza kangaka.

Enye iwukuthi iqukethe izinsimbi eziyigugu. I-catalyst yezindlela ezintathu iqukethe igobolondo, ungqimba olumanzi, umthwali kanye ne-catalyst coating. Izinsimbi ezingavamile ezifana ne-Pt (i-platinum), i-Rh (i-Rhodium) , i-PD (i-palladium) nezinsimbi zomhlaba ezingavamile ezihlanganisa i-CE (cerium) ne-LA (lanthanum) zisetshenziswa ezintweni ezimbozwe i-catalyst. Yingakho bephinda basebenzise iziguquli ze-catalytic zezindlela ezintathu.Kuphinde kube isizathu esenza abashayeli bakudala bathathe isiguquli se-catalytic esidala sezindlela ezintathu lapho beshintsha esisha.

Okwesibili, ngoba ukukhiqizwa kwezidingo zobuchwepheshe eziphezulu. Emakethe kungenza abakhiqizi be-converter bekhwalithi ephezulu bezindlela ezintathu, ngakho-ke futhi inyuse intengo yesiguquli sendlela ezintathu. Yiqiniso, kukhona abaguquli be-catalytic abashibhile bezindlela ezintathu, kodwa kufanele sinake izinga labaguquli bezindlela ezintathu ngeke babangele amandla emoto kuphela, ukusetshenziswa kukaphethiloli kanye neminye imiphumela emibi, kodwa futhi kuthinte ukuhlolwa kwemoto. . Futhi impilo yesevisi izofinyezwa kakhulu, izindleko eziphelele azincane.

Ukwehluleka & Imbangela

Amaphutha ajwayelekile we-three-way catalyst yilawa:

1.Isibani sephutha sikhanyisiwe, ikhodi yephutha evamile i-P0420 noma i-P0421 (emele ukuguqulwa okuphansi kokusebenza kahle).

2.I-exhaust gas idlula izinga, elithinta imoto yokuhlola.

3. Izobangela imoto ukuthi ijubane kancane, amandla aphansi.

4.Ezinye izinkinga, njengomsindo ongajwayelekile, ukuncibilika, ukuhlukana, ukuwa.

Kunezizathu ezintathu zalokhu kwehluleka:

Esokuqala izinga likaphethiloli, uphethiloli ku-lead nesibabule kanye nezinto zokugcoba ku-phosphorus kanye ne-zinc kuzodala umonakalo omkhulu ku-catalyst yezindlela ezintathu.Umthofu yiwona oyingozi kakhulu. Olunye ucwaningo lubonisa ukuthi noma ngabe kusetshenziswe ibhokisi likaphethiloli onomthofu kuphela, lizodala ukwehluleka okukhulu kwesiguquli se-catalytic esinezindlela ezintathu. Kodwa izwe lethu kakade waqaphela imoto uphethiloli unleaded, lokhu kakade akudingeki ukhathazeke.

Okwesibili ukucabangela iphutha lenjini, njengokusha kwenjini, ingxube ewugqinsi kakhulu noma ezacile kakhulu, ukushiswa kukawoyela wenjini, njll. , nakho kuzoba nomthelela ongathi sína kusiguquli se-catalytic yezindlela ezintathu.

Okokugcina impilo yokuklama, ukusetshenziswa kwemoto yokuguqula izindlela ezintathu akulona iphutha elikhulu, kungasetshenziswa ukuguga kwayo okungokwemvelo, abangani bemoto basindisa izinkinga eziningi.

Indlela Yokuvikela

Okubaluleke kakhulu futhi kubiza kakhulu, siyelula kanjani impilo ye-catalyst yezindlela ezintathu?

Indlela eqondile kakhulu ukuhlanza njalo, umjikelezo wokuhlanza onconyiwe ungama-40-50,000 km. Ukukhetha uwoyela ukuhlangabezana nezidingo zemoto yokuqala, ungavumeli izinga likawoyela lidlule umkhawulo wegeji likawoyela. (ezinye izinhlobo zakwa-VW zinowoyela othi“Uwoyela omningi ekamelweni uzolimaza i-catalytic reactor” isaziso, abashayeli bakwa-VW banganaka)

Khetha futhi uphethiloli ukuze uhlangabezane nezidingo zemoto, ungaphelelwa uphethiloli, ngangokunokwenzeka ukugcina uphethiloli owanele. Izithasiselo zikaphethiloli azikwazi ukusebenzisa i-manganese, imikhiqizo yensimbi.
