I-catalytic converter ihlala isikhathi esingakanani?

Isiguquli se-catalytic siguqula ukungcola ohlelweni lwe-exhaust lube ukungcola okunobuthi obuncane sisebenzisa indlela yokunciphisa i-redox. Isiguquli se-catalytic sitholakala kusistimu yokukhipha umoya wemoto yakho futhi sibalulekile ukuze ulawule ukukhishwa kwemoto yakho. Ishisa intuthu ephumayo futhi iguqule ibe umhwamuko wamanzi nomoya-mpilo. Ukukhishwa okuyinhloko kwemoto yakho kufaka igesi ye-nitrogen, i-carbon dioxide (CO2), umhwamuko wamanzi (H2O), i-carbon monoxide (CO), ama-hydrocarbon (VOC) nama-oxide e-nitrogen (NO ne-NO2).

Izimoto eziningi zesimanje zifakelwe i-converter yezindlela ezintathu ze-catalytic. Isigaba sokuqala sesiguquli se-catalytic siyi-reductive catalyst. Kulesi sigaba, i-rhodium ne-platinum kunciphisa ukukhishwa kwe-nitrogen oxide. Isigaba sesibili yi-oxidation catalyst. Lapha, i-carbon monoxide engashiswa nama-hydrocarbon atholakala ngokuwashisa ku-palladium ne-platinum catalyst. Uhlelo lokulawula luyisigaba sesithathu futhi lulawula ukugeleza kwamagesi akhipha umoya. Lolu lwazi lusetshenziselwa ukulawula isistimu yokujova uphethiloli ngenzwa ye-oxygen. Inzwa izothumela ulwazi enjinini mayelana nokuthi ingakanani i-oxygen ekukhishweni. Uma kunomoya-mpilo omningi noma omncane kakhulu, ikhompuyutha yenjini ingakhuphula noma yehlise inani ngokulungisa isilinganiso somoya/samafutha. Lokhu kuqinisekisa ukuthi kunomoya-mpilo owanele kumagesi akhipha umoya ukuze i-oxidation catalyst ikwazi ukushisa kahle i-carbon monoxide nama-hydrocarbon.

Isiguquli se-catalytic sisebenza emazingeni okushisa aphezulu kakhulu, ngakho-ke akuvamile ukuthi sehluleke. Isibonelo, ukushisa kabi kusistimu yenjini kungashisa futhi kulimaze isiguquli se-catalytic. Ngaphezu kwalokho, i-exhaust ingangena ku-converter ye-catalytic, eyenza ingcindezi emuva futhi ibangele injini ukuba imiswe. Lokhu kuzokwenza ukuthi imoto yakho ime ngenkathi ushayela. Isiguquli se-catalytic singaphinda sonakaliswe ngenxa yemithelela evela kudoti womgwaqo. Buka lezi zimpawu ezilandelayo ezibonisa ukwehluleka kwesiguquli se-catalytic:
