Catalytic converter inotora nguva yakareba sei?

Iyo catalytic inoshandura inoshandura zvinosvibisa mu exhaust system kuita zvishoma zvinosvibisa zvinosvibisa uchishandisa redox yekudzikisa nzira. Iyo catalytic inoshandura iri mumotokari yako exhaust system uye yakakosha kudzora kubuda kwemotokari yako. Inopisa zvinobuda uye inoashandura kuita mhute yemvura uye oxygen. Hutsi hwemotokari yako hunosanganisira gasi renitrogen, carbon dioxide (CO2), mhute yemvura (H2O), carbon monoxide (CO), mahydrocarbon (VOC) nemaokisijeni enitrogen (NO neNO2).

Mota zhinji dzemazuva ano dzakashongedzerwa netatu-nzira catalytic converter. Nhanho yekutanga yecatalytic converter inoderedza catalyst. Panguva ino, rhodium neplatinum zvinoderedza nitrogen oxide. Nhanho yechipiri ndeye oxidation catalyst. Pano, carbon monoxide uye mahydrocarbon asina kupiswa anodzoserwa nekupisa palladium neplatinum catalyst. Iyo control system ndiyo nhanho yechitatu uye inodzora kuyerera kwemagasi ekupedza. Ruzivo urwu runoshandiswa kudzora jekiseni remafuta kuburikidza neokisijeni sensor. Iyo sensor inotumira ruzivo kune injini nezvekuti yakawanda sei okisijeni iri mukubuda. Kana okisijeni yakawandisa kana yakawandisa, komputa yeinjini inogona kuwedzera kana kuderedza huwandu nekugadzirisa reshiyo yemhepo/mafuta. Izvi zvinoita kuti pave neokisijeni yakakwana mumagasi ekuburitsa kuitira kuti oxidation catalyst ikwanise kupisa kabhoni monoxide nemahydrocarbon.

Iyo catalytic inoshandura inoshanda pakupisa kwakanyanya, saka hazvina kujairika kuti itadze. Semuenzaniso, misfires mujini system inogona kupisa uye kukuvadza catalytic converter. Mukuwedzera, kupera kunogona kupinda mushanduri inoshandura, iyo inogadzira kumashure kumanikidzwa uye inoita kuti injini imire. Izvi zvinoita kuti mota yako imire paunenge uchityaira. Iyo catalytic inoshandura inogona zvakare kukuvara nekuda kwekukanganisa kubva kumarara emumugwagwa. Tarisa uone zvinotevera zviratidzo zvinoratidza kutadza kwekushandura shanduko:
