Iyo catalytic inoshandura ndiyo inonyanya kukosha yekunze yekunatsa mudziyo yakaiswa mu exhaust system, iyo inogona kushandura magasi anokuvadza akadai CO, HC uye NOx kubva mumhepo yekuburitsa kuita isingakuvadzi kabhoni dhisiki, mvura uye nitrogen kuburikidza neoxidation uye kuderedza.Kana iyo yakakwira-kupisa muswe gasi ichipfuura nepakati yekuchenesa unit, iyo yekuchenesa mumiriri inosimudzira inosimudzira basa reCO, HC uye NOx uye inovasimudzira kuita imwe oxidation yekudzikisa kemikari reaction, umo CO inoiswa oxid kune isina ruvara uye. kwete-chepfu carbon dioxide gasi pakupisa kukuru;Mishonga yeHC inoiswa oxidized kumvura (H20) uye carbon dioxide pakupisa kukuru;NOx inoderedzwa kuita nitrogen uye oksijeni.Iwo matatu magasi anokuvadza anova magasi asingakuvadzi, kuitira kuti gasi remuswe richeneswe.

Iyo inotakura chikamu cheiyo catalyst chidimbu che porous ceramic zvinhu, iyo yakaiswa mune yakakosha pombi yekupedza.Inonzi mutakuri nekuti haitore chikamu mune zvinokonzeresa maitiro, asi yakafukidzwa neplatinamu, rhodium, palladium uye mamwe masimbi anokosha.Inogona kushandura HC uye CO mukuburitsa gasi mumvura uye CO2, uye kusvibisa NOx kuita nitrogen uye oksijeni.HC uye CO magasi ane chepfu.Kuwedzeredza inhalation kunotungamira kurufu, nepo NOX ichitungamira zvakananga kune photochemical smog.

Pasi peyakajairika kushanda mamiriro ecatalytic converter, nekuda kwehuwandu hukuru hwekuita kupisa kunogadzirwa neiyo oxidation reaction, kuita kwecatalytic converter kunogona kutongwa nekuenzanisa kwekushisa.Iyo yekubuda tembiricha yecatalytic inoshandura ichave inosvika 10 ~ 15% yakakwira kupfuura tembiricha yekupinza.Kune akawanda akajairwa anoshandura anoshandura, tembiricha yekubuda kwecatalytic inoshandura ichave 20 ~ 25% yakakwirira kupfuura tembiricha yekupinza.

Huchi yesimbi substrate catalyst ine zvakanakira kupisa nekukurumidza, vhoriyamu shoma, yakakwirira mechanical simba, yakakurumbira kupisa-resistant, etc. Inoshandiswa zvakanyanya mumidhudhudhu nemotokari (peturu injini uye dizeli) exhaust system.Tinogona kusangana neiyo emission standard Euro II, Euro III, Euro IV, Euro V, EPA uye CARB.
