Molao-motheo oa ho sebetsa oa Exhaust Catalytic Converter
Molao-motheo oa tšebetso oa exhaust catalytic converter ke o latelang: Ha mosi o tsoang koloing-mocheso o phahameng o feta sesebelisoa sa tlhoekiso, ntho e hloekisang ka har'a catalytic converter e ntlafatsa tšebetso ea CO, HC, le likhase tsa NOx, e khothalletsa ho itseng ha oxidation{1}e fokotsa tšebetso ea lik'hemik'hale. Haholo-holo, CO e kenngoa ka oxidized mochesong o phahameng hore e be carbon dioxide e se nang 'mala, e seng{3} e seng chefo; Metsoako ea HC e na le oxidized ka mocheso o phahameng ho kena metsing (H2O) le carbon dioxide; mme NOx e fokotsehile ho ba naetrojene le oksijene. Likhase tsena tse tharo tse kotsi li fetoloa likhase tse se nang kotsi, kahoo li hloekisa mosi oa koloi.
Exhaust catalytic converter e tšoana le muffler. Bokaholimo ba eona bo entsoe ka cylindrical ho sebelisoa lishiti tse habeli- tse entsoeng ka tšepe. Insulation material-asbestos fiber felt-e behiloe lipakeng tsa-mashiti a mealo a mabeli. Moemeli oa tlhoekiso o behiloe ka hare, o kenngoe lipakeng tsa mesh partitions. Moemeli oa tlhoekiso o na le sejari le sesebelisoa. Sesebelisoa hangata se entsoe ka aluminium oxide, 'me sebopeho sa sona e ka ba sechitja, polygonal, kapa karohano ea letlooeng. Moemeli oa tlhoekiso, eo hape a tsejoang e le catalyst, ke sona se hlileng se sebetsang e le mokelikeli. Li-catalysts hangata li entsoe ka platinum, rhodium kapa palladium. Ho fafatsa e 'ngoe ea tsena holim'a sejari ke ntho e hloekisang.
