Ƙa'idar Aiki Na Exhaust Catalytic Converter
Ƙa'idar aiki na mai juye catalytic mai jujjuyawa shine kamar haka: Lokacin da babban abin hawa - zafin abin hawa ya wuce ta cikin na'urar tsarkakewa, wakili mai tsarkakewa a cikin mai canza kuzari yana haɓaka ayyukan iskar CO, HC, da NOx, yana haɓaka wasu halayen oxidation{1}} rage halayen sinadarai. Musamman, CO yana oxidized a babban yanayin zafi zuwa mara launi, mara - carbon dioxide mai guba; HC mahadi suna oxidized a high yanayin zafi cikin ruwa (H2O) da kuma carbon dioxide; kuma NOx yana raguwa zuwa nitrogen da oxygen. Waɗannan iskar gas guda uku masu cutarwa suna rikiɗa su zama iskar da ba ta da lahani, don haka ana tsarkake hayakin abin hawa.
Mai juye catalytic mai jujjuyawa yana kama da muffler. Wurin da yake wajen an yi shi ne da tsarin siliki ta hanyar amfani da zanen karfen bakin karfe biyu{1}. Ana sanya kayan insulation -asbestos fiber feel{4}} a tsakanin zanen gado biyu-. Ana sanya wakili mai tsarkakewa a ciki, sandwiched tsakanin sassan raga. Wakilin tsarkakewa ya ƙunshi mai ɗauka da mai kara kuzari. Gabaɗaya mai ɗaukar kaya an yi shi da aluminum oxide, kuma siffarsa na iya zama mai siffar zobe, polygonal, ko ɓangaren raga. Wakilin tsarkakewa, wanda kuma aka sani da mai haɓakawa, shine ainihin abin da ke aiki azaman mai kara kuzari. Ana yin abubuwan haɓakawa da yawa daga platinum, rhodium, ko palladium. Fesa ɗaya daga cikin waɗannan akan mai ɗaukar kaya shine wakili mai tsarkakewa.
