Iinkxaso zeCatalyst zidlala indima ebalulekileyo ekunciphiseni ukukhutshwa kwezithuthi, ngakumbi kwiinjini zedizili.Akukho nanye kwii-catalysts ezikhoyo ezisebenza ngokwazo.Bafuna umphathiswa ukuba enze umsebenzi wabo ngokufanelekileyo.

I-DPF catalyst, i-SCR catalyst, i-DOC catalyst, kunye ne-TWC catalyst zizinto ezenza inkqubo yokuguqula i-catalytic.Iicatalysts ze-DPF zidlala indima ebalulekileyo ekubanjeni nasekufunxeni amasuntswana ekhabhoni ayingozi kumbhobho we-injini ye-diesel.Ii-DPF zisebenzisa i-honeycomb structure ukuze zibambe umle kunye namasuntswana othuthu.Ziqulethe iicatalysts zetsimbi ezenziwe ngeplatinam, i-palladium kunye nezinye iintsimbi ezinqabileyo zomhlaba ukunyusa ukuphendula kwe-oxidation kunye nokutshisa amasuntswana omsizi.

I-catalyst ye-SCR isebenzisa isisombululo se-urea enamanzi, i-AdBlue, ukusabela nge-diazo oxides ekhutshwayo.Inkqubo ibandakanya ukunciphisa i-nitrogen oxides kwi-nitrogen kunye namanzi, isicwangciso esibalulekileyo sokunciphisa ukungcola kwiinjini ze-diesel.Isisombululo se-AdBlue sifafazwe kwi-exhaust gas flow kunye ne-nitrogen oxides isabela kwi-SCR catalyst ukwenza igesi ye-nitrogen engenabungozi.

I-DOC catalyst yi-catalyst ye-oxidation enoxanduva lokuguqula i-carbon monoxide kunye ne-hydrocarbons ibe yi-carbon dioxide namanzi.Yenzelwe ukuba i-oxidize la masuntswana angcolisayo abe angenabungozi.

Okokugqibela, i-catalyst ye-TWC yindlela eneendlela ezintathu eguqula i-carbon monoxide eyingozi, i-nitrogen oxides kunye nee-hydrocarbons zibe yi-carbon dioxide engenabungozi kunye namanzi.Ii-catalysts ze-TWC zidla ngokusetyenziswa kwiinjini zepetroli kwaye zisebenza ngakumbi kunee-DOC catalysts.

Ii-catalysts ezichazwe ngasentla zifuna inkxaso ukuze zisebenze ngokufanelekileyo.Inkxaso ye-catalyst yinxalenye ebalulekileyo yenkqubo yokuguqula, inceda ukubamba izinto ezingcolileyo, ziguqule zibe zizinto ezingenabungozi, kwaye kubaluleke kakhulu, iphucula ukusebenza kwe-injini.Inkxaso isebenza njengenkxaso yenkxaso ye-catalysts yensimbi kwaye ibalulekile ekunyuseni izinga lokuphendula.Yenza kwakhona i-catalytic converter yomelele.

Ukusebenza kwe-catalyst kuxhomekeke kwinkxaso yayo.Iinkxaso eziyilwe ngendlela engafanelekanga zinokubaleka okanye zivale imibhobho yokukhupha, zithintele ukubanjwa kwamasuntswana, zithintele ukusabela kweekhemikhali, okanye zide zonakalise izixhobo zokukhupha umoya.Ke ngoko, kubalulekile ukukhetha izixhobo ezifanelekileyo zenkxaso, njenge-alumina, i-silicon carbide okanye i-ceramics.

Ukuqukumbela, inkqubo yokuguqula i-catalytic yinxalenye ebalulekileyo yemoto yanamhlanje.Iicatalysts ze-DPF, ii-SCR catalysts, i-DOC catalysts, kunye ne-TWC catalysts zisebenza ngekonsathi kunye nenkxaso ye-catalyst ukuze bafezekise imisebenzi yabo ngokufanelekileyo.Iinkxaso zidlala indima ebalulekileyo ekubambiseni ungcoliseko kunye nokwenza ukuba izinto ezibangela ukuba zisebenze ngokufanelekileyo ukwandisa ukusebenza kwe-injini, ukunciphisa ukukhutshwa kunye nokuphucula ukuzinza kokusingqongileyo.Ukukhetha izinto ezifanelekileyo zokuphatha kubalulekile ekuqinisekiseni ukuba inkqubo yakho yokuguqula i-catalytic iya kusebenza ngokufanelekileyo kwaye ibonelele ngenkonzo yexesha elide.
