Catalyst inotsigira inoita basa rakakosha mukudzikisa kuburitswa kwemotokari, kunyanya muinjini dzedhiziri.Hapana chimwe chezvishandiso chiripo chinoshanda chega.Vanoda mutakuri kuti aite basa ravo nemazvo.

Iyo DPF catalyst, iyo SCR catalyst, iyo DOC catalyst, uye TWC catalyst zvinhu zvinoumba inoshandura inoshandura system.DPF catalysts inoita basa rakakosha mukuteya nekutora kabhoni inokuvadza mumhepo yedhiziri.MaDPF anoshandisa muzinga wehuchi kuteya soot nemadota.Iwo ane simbi inokonzeresa yakagadzirwa neplatinamu, palladium uye mamwe masimbi epasi asingawanzo kusimudzira maitiro oxidation uye kupisa soot particles.

Iyo SCR catalyst inoshandisa aqueous urea solution, AdBlue, kuita neakabuda diazo oxides.Iyo sisitimu inosanganisira kudzikiswa kwenitrogen oxides kuita nitrogen nemvura, zano rakakosha rekudzikisa zvinosvibisa muinjini dzedhiziri.Mhinduro yeAdBlue inopfapfaidzwa mukati mekuyerera kwegasi uye maokisi enitrogen anoita muSCR catalyst kuumba isingakuvadze nitrogen gasi.

A DOC catalyst is oxidation catalyst inokonzera kushandura carbon monoxide uye hydrocarbons kuita carbon dioxide nemvura.Yakagadzirirwa kuita oxidize zvidimbu zvinosvibisa izvi kuita zvisingakuvadzi.

Chekupedzisira, iyo TWC catalyst inzira nhatu-catalyst inoshandura inokuvadza kabhoni monoxide, nitrogen oxides uye hydrocarbons kuita isingakuvadzi kabhoni dhaikisaidhi nemvura.TWC catalysts inowanzoshandiswa muinjini dzepeturu uye inoshanda zvakanyanya kupfuura DOC catalysts.

Macatalyst atsanangurwa pamusoro apa anoda rutsigiro kuti ashande nemazvo.Iyo catalyst tsigiro chikamu chakakosha cheiyo inoshandura sisitimu, inobatsira kubata zvinosvibisa, kuishandura kuita zvinhu zvisingakuvadze, uye zvakanyanya kukosha, inovandudza injini kushanda zvakanaka.Rutsigiro runoshanda sechimiro chekutsigira chesimbi catalysts uye yakakosha pakuwedzera chiyero chekuita.Inoitawo kuti catalytic converter igare yakasimba.

Kuitwa kwechikafu kunoenderana nekutsigirwa kwayo.Zvisikwa zvakagadzirirwa zvitsigiro zvinogona kutiza kana kuvhara mapombi emhepo, kukanganisa kubatwa kwechikamu, kukanganisa kuita kwemakemikari, kana kukuvadza zvinokonzeresa.Naizvozvo, zvakakosha kuti usarudze chinhu chakakodzera chekutsigira, senge alumina, silicon carbide kana ceramics.

Mukupedzisa, iyo catalytic converter system chikamu chakakosha chemotokari yemazuva ano.DPF catalysts, SCR catalysts, DOC catalysts, uye TWC catalysts vanoshanda pamwe chete nerutsigiro rwecatalyst kuti vaite mabasa avo nemazvo.Tsigiro dzinoita basa rakakosha mukuteya zvinosvibisa uye kugonesa zvinokonzeresa kuti zvishande zvakanangana kuti iwedzere kushanda kweinjini, kuderedza kuburitsa uye kunatsiridza kuchengetedza kwezvakatipoteredza.Kusarudza iyo yakakodzera yekutakura zvinhu kwakakosha pakuona kuti yako catalytic converter system inoshanda nemazvo uye inopa basa renguva refu.
