Mofetoleli oa catalytic o fetola litšila tse ka har'a sistimi ea motumo hore e be litšila tse seng kotsi haholo li sebelisa mokhoa oa ho fokotsa redox. Catalytic converter e sebakeng sa koloi ea hau mme e bohlokoa ho laola tlhahiso ea koloi ea hau. Ha e le hantle e chesa mesi ebe e e fetola mouoane oa metsi le oksijene. Mesi e meholo ea koloi ea hau e kenyelletsa khase ea nitrogen, carbon dioxide (CO2), mouoane oa metsi (H2O), carbon monoxide (CO), hydrocarbons (VOC) le oxides of nitrogen (NO le NO2).
Likoloi tse ngata tsa sejoale-joale li na le li-converter tsa litsela tse tharo. Mokhahlelo oa pele oa converter ea catalytic ke sesebelisoa se fokotsang. Mothating ona, rhodium le platinum li fokotsa tlhahiso ea nitrogen oxide. Mokhahlelo oa bobeli ke oxidation catalyst. Mona, carbon monoxide e sa chesoang le li-hydrocarbon li fumanoa ka ho li chesa holim'a palladium le platinum catalyst. Sistimi ea taolo ke mohato oa boraro mme o laola phallo ea likhase tsa ho tsoa. Boitsebiso bona bo sebelisetsoa ho laola tsamaiso ea ente ea mafura ka sensor ea oksijene. Sensor e tla romella tlhahisoleseling ho enjene mabapi le hore na oksijene e kae ka har'a mosi. Haeba ho na le oksijene e ngata haholo kapa e nyane haholo, komporo ea enjene e ka eketsa kapa ea fokotsa chelete ka ho lokisa karolelano ea moea le mafura. Sena se etsa bonnete ba hore ho na le oksijene e lekaneng likhase tsa mouoane e le hore sesebelisoa sa oxidation se ka chesa carbon monoxide le hydrocarbon ka katleho.
Catalytic converter e sebetsa ka mocheso o phahameng haholo, kahoo ho tloaelehile hore e hlolehe. Ka mohlala, mello e fosahetseng tsamaisong ea enjene e ka chesa le ho senya catalytic converter. Ho phaella moo, mokelikeli o ka kenya mochine oa ho fetolela, o bakang khatello ea morao 'me o etsa hore enjene e eme. Sena se tla etsa hore koloi ea hau e eme ha u ntse u khanna. Catalytic converter le eona e ka senyeha ka lebaka la litlamorao tse tsoang lithakong tsa litsela. Sheba matšoao a latelang a bontšang ho hloleha ha li-converter:
- Moruo o fokolang oa mafura
- Koloi ha e sebetse hantle, joalo ka ho ema ha motho a ntse a khanna kapa ho tsieleha
- Enjene e fosahetse
- Sheba lebone la enjene
- Monko oa mahe a bolileng
Hobane catalytic converter e ka hloleha kapa ea hloleha ha nako e ntse e ea, converter ea catalytic e kanna ea hloka ho nkeloa sebaka.
