Indima yenzwa ye-post-oxygen.
Umsebenzi wenzwa ukuthola ukuthi ngabe kukhona yini i-oxygen eningi egesini yokukhipha injini ngemva kokusha, okungukuthi, okuqukethwe yi-oxygen, nokuguqula okuqukethwe yi-oxygen kube isignali ye-voltage ukuze idluliselwe kukhompyutha yenjini, ukuze injini ikwazi ukufeza ukulawula okuvaliwe okune-air factor eningi njengomgomo; Qinisekisa ukuthi i-catalytic converter enezindlela ezintathu inekhono eliphezulu lokuguqula izinto ezintathu ezingcolisayo ku-hydrocarbon yokukhipha (HC), i-carbon monoxide (CO) kanye ne-nitrogen oxide (NOX), futhi ikhulise ukuguqulwa nokuhlanzwa kwezinto ezingcolisayo ezikhishwayo.
Imisebenzi yenzwa yile:
1, inzwa eyinhloko ye-oxygen ifaka isici se-heating zirconia se-hot rod, i-heating rod by (ECU) computer control, lapho umoya ungena kancane (izinga lokushisa lokukhipha umoya liphansi) ukugeleza kwamanje kuya ku-heating rod heating sensor, okuvumela ukutholakala okunembile kokuhlushwa kwe-oxygen.
2. Imoto ifakwe izinzwa ezimbili ze-oxygen, enye ngaphambi kwe-three-way catalytic converter kanye nenye ngemuva. Indima yangaphambili ukuthola isilinganiso somoya-fuel senjini ezimweni zokusebenza ezahlukene, bese ikhompyutha ilungisa inani lokufakwa kukaphethiloli futhi ibale isikhathi sokusha ngokuya ngesignali. Into eyinhloko ngemuva ukuthola umsebenzi we-three-way catalytic converter! Okusho ukuthi, izinga lokuguqulwa kwe-catalyst. Ngokuqhathanisa nedatha ye-front oxygen sensor, kuyisisekelo esibalulekile sokuthola ukuthi i-three-way catalytic converter isebenza kahle (kuhle noma kubi).
Yini eyenziwa yinzwa yomoya-mpilo ephukile emotweni?
01 Ukusetshenziswa kukaphethiloli okwandisiwe
Ukulimala kwenzwa ye-oxygen yangemuva kuzoholela ekusetshenzisweni kukaphethiloli okwandisiwe. Lokhu kungenxa yokuthi ukufakwa kwekhabhoni kunzwa ye-oxygen kungaholela ekukhishweni kwesignali okungavamile, okuthi kamuva kuthinte isilinganiso sokuxubana kwenjini, okwenza ingalingani. Lapho isilinganiso sengxube senjini singalingani, ukuze kugcinwe ukushisa okuvamile, injini izolawula ukufakwa kukaphethiloli okwengeziwe, okuholela ekuxubeni okuningi kakhulu, okuthi kamuva kwandise ukusetshenziswa kukaphethiloli. Ngaphezu kwalokho, ngenxa yokwehluleka kwenzwa ye-oxygen, ulwazi olungalungile oludluliselwayo lungabangela ukuthi okuqukethwe kwe-oxygen yenjini kube phezulu kakhulu, okuholela ekusetshenzisweni kukaphethiloli okwandisiwe. Ngakho-ke, uma inzwa ye-oxygen yonakele, kufanele ishintshwe ngesikhathi ukuze kugwenywe ukusetshenziswa kukaphethiloli okwandisiwe.
02 Ukukhishwa kokungcola kuyanda
Ukulimala kwenzwa ye-oxygen yangemuva kuzoholela ekukhishweni okukhulu komoya-mpilo emotweni. Lokhu kungenxa yokuthi inzwa ye-post-oxygen iyingxenye ebalulekile yokusebenza okuvamile kwe-catalytic converter enezindlela ezintathu. Lapho inzwa ye-post-oxygen ihluleka, i-catalytic converter enezindlela ezintathu ayikwazi ukusebenza kahle, ukuze ingakwazi ukuguqula ngempumelelo izinto eziyingozi zibe izinto ezingenangozi. Ngale ndlela, imoto izokhipha ukungcola okwengeziwe ngesikhathi senqubo yokushayela, okuholela ekukhishweni komoya-mpilo ngokweqile.
03 Sheshisa kancane kancane
Ukulimala kwenzwa ye-oxygen yangemuva kuzokwenza imoto yehle ijubane. Lokhu kungenxa yokuthi inzwa ye-afteroxygen inesibopho sokuqapha inani le-oxygen ekhishwa yinjini nokudlulisela lolu lwazi ohlelweni lokulawula ikhompyutha yemoto. Lapho inzwa ye-afteroxygen yonakele, ikhompyutha yemoto ayikwazi ukuthola ngokunembile lolu lwazi olubalulekile, ukuze injini ingalawulwa futhi ilungiswe ngokunembile. Lokhu kungaholela ekunciphiseni ukusebenza kahle kwenjini, okuthinta ukusebenza kokusheshisa kwemoto, okwenza yehle ijubane.
04 Isibani sokwehluleka kwenjini sizokhanya
Ngemva kokuba inzwa ye-oxygen yonakele, ukukhanya kwenjini kuzokhanya. Lokhu kungenxa yokuthi inzwa ye-afteroxygen inesibopho sokuqapha okuqukethwe kwe-oxygen okukhishwa yinjini nokudlulisa idatha ohlelweni lokulawula lwe-elekthronikhi lwemoto. Lapho inzwa ye-afteroxygen yonakele, ayikwazi ukunikeza le datha ngokunembile, okuholela ekutheni uhlelo lokulawula lwe-elekthronikhi alukwazi ukwahlulela ngokunembile isimo sokusebenza kwenjini. Kulokhu, uhlelo lokulawula lwe-elekthronikhi luzocabanga ukuthi kukhona ukwehluleka kwenjini okungenzeka, ngakho-ke ukukhanya kwenjini kuzokwazisa umshayeli.
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
