Umgomo osebenzayo we-catalytic converter enezindlela ezintathu uthi: lapho izinga lokushisa eliphezulu lokukhipha umoya emotweni ngokusebenzisa idivayisi yokuhlanza, i-purifier ku-catalytic converter enezindlela ezintathu izothuthukisa umsebenzi wezinhlobo ezintathu zegesi i-CO, ama-hydrocarbon kanye ne-NOx, ukukhuthaza ukusabela kwayo kwamakhemikhali okunciphisa i-oxidation, lapho i-CO oxidation ekushiseni okuphezulu iba yigesi engenambala, engenabuthi ye-carbon dioxide; Ama-hydrocarbon ancibilikisa emanzini (H2O) kanye ne-carbon dioxide ekushiseni okuphezulu; i-NOx yehliswa ibe yi-nitrogen kanye ne-oxygen. Izinhlobo ezintathu zegesi eyingozi ibe yigesi engenangozi, ukuze i-exhaust yemoto ihlanzwe. Uma kutholakala i-oxygen, isilinganiso somoya-fuel sinengqondo.
Ngenxa yekhwalithi embi kaphethiloli eShayina, uphethiloli uqukethe i-sulfur, i-phosphorus kanti i-antiknock agent MMT iqukethe i-manganese. Lezi zingxenye zamakhemikhali zizokwakha ama-chemical complexes ebusweni be-oxygen sensor kanye nangaphakathi kwe-three-way catalytic converter enegesi yokukhipha umoya ekhishwa ngemva kokusha. Ngaphezu kwalokho, ngenxa yemikhuba emibi yokushayela yomshayeli, noma ukushayela isikhathi eside emigwaqweni eminyene, injini ivame ukuba sesimweni sokusha esingaphelele, okuzokwakha ukuqongelela kwekhabhoni ku-oxygen sensor kanye ne-three-way catalytic converter. Ngaphezu kwalokho, izindawo eziningi zezwe zisebenzisa uphethiloli we-ethanol, onomphumela wokuhlanza onamandla, uzohlanza isikali ekamelweni lokusha kodwa awukwazi ukubola nokusha, ngakho-ke ngokukhishwa kwegesi engcolile, lokhu kungcola kuzobekwa ebusweni be-oxygen sensor kanye ne-three-way catalytic converter. Kungenxa yezici eziningi ezenza imoto ngemva kokushayela isikhathi esingamakhilomitha amaningi, ngaphezu kokuqongelela kwekhabhoni ku-valve yokungenisa kanye negumbi lokushiswa, izophinde ibangele ukwehluleka kwenzwa yomoya-mpilo kanye nokwehluleka kokuguqulwa kwe-catalytic okunezindlela ezintathu, ukuvaleka kwe-catalytic converter okunezindlela ezintathu kanye ne-valve ye-EGR evinjiwe yi-sediment ebambeke kanye nokunye ukwehluleka, okuholela ekusebenzeni okungajwayelekile kwenjini, okuholela ekusetshenzisweni kukaphethiloli okwandisiwe, ukwehla kwamandla kanye nokukhishwa kwegesi okungaphezu kwesilinganiso kanye nezinye izinkinga.
Ukugcinwa njalo kwenjini yendabuko kukhawulelwe ekugcinweni okuyisisekelo kwesistimu yokugcoba, uhlelo lokungenisa kanye nohlelo lokuphakelwa kukaphethiloli, kodwa akukwazi ukuhlangabezana nezidingo zokugcinwa eziphelele zesistimu yokugcoba yesimanje yenjini, uhlelo lokungenisa, uhlelo lokuphakelwa kukaphethiloli kanye nohlelo lokukhipha uphethiloli, ikakhulukazi izidingo zokugcinwa kwesistimu yokulawula ukukhishwa komoya. Ngakho-ke, noma ngabe imoto igcinwa isesimweni esijwayelekile isikhathi eside, kunzima ukugwema izinkinga ezingenhla.
Ukuphendula amaphutha anjalo, izinyathelo ezithathwa amabhizinisi okulungisa zivame ukufaka esikhundleni sezinzwa ze-oxygen kanye nama-catalytic converter anezindlela ezintathu. Kodwa-ke, ngenxa yenkinga yezindleko zokufaka esikhundleni, izingxabano phakathi kwamabhizinisi okulungisa kanye namakhasimende ziyaqhubeka. Ikakhulukazi lezo ezingahambisani nokuphila kwenkonzo yokushintsha izinzwa ze-oxygen kanye nama-catalytic converter anezindlela ezintathu, zivame ukuba yimbangela yezingxabano, amakhasimende amaningi aze athi inkinga ibangelwa yikhwalithi yemoto.
