Indima yenzwa ye-post-oxygen.
Umsebenzi wenzwa ukunquma ukuthi ingabe kukhona i-oksijini eyeqile kugesi yokukhipha injini ngemuva kokusha, okungukuthi, okuqukethwe komoyampilo, futhi iguqule okuqukethwe komoyampilo ibe isignali kagesi ukuze idluliselwe kukhompyutha yenjini, ukuze injini ikwazi ukuzuza ukulawulwa kwe-loop evaliwe enesici somoya esiningi njengomgomo; Qinisekisa ukuthi isiguquli se-catalytic sezindlela ezintathu sisebenza kahle kakhulu ekuguquleni izinto ezintathu ezingcolisayo ku-exhaust hydrocarbon (HC), i-carbon monoxide (CO) ne-nitrogen oxide (NOX), futhi ikhulise ukuguqulwa nokuhlanzwa kokungcola.
Imisebenzi ye-sensor yilezi:
I-1, inzwa ye-oxygen eyinhloko ihlanganisa isici se-zirconia sokushisa se-hot rod, i-heater rod by (ECU) isilawuli sekhompiyutha, lapho ukungena komoya kukuncane (izinga lokushisa lokukhipha umoya liphansi) ukugeleza kwamanje kunzwa yokushisa induku yokushisa, okuvumela ukutholwa okunembile kokuhlushwa komoya-mpilo.
2. Imoto ifakwe izinzwa ezimbili ze-oxygen, eyodwa ngaphambi kwesiguquli se-catalytic yezindlela ezintathu kanye neyodwa ngemva. Indima yangaphambili iwukubona isilinganiso sikaphethiloli womoya wenjini ezimeni zokusebenza ezihlukene, bese ikhompuyutha ilungisa inani lomjovo kaphethiloli bese ibala isikhathi sokubasa ngokwesiginali. Into eyinhloko ngemuva ukuthola umsebenzi we-converter yezindlela ezintathu ze-catalytic! Okusho ukuthi, izinga lokuguqulwa kwe-catalyst. Ngokuqhathanisa nedatha yenzwa ye-oxygen yangaphambili, kuyisisekelo esibalulekile sokuthola ukuthi isiguquli se-catalytic sezindlela ezintathu sisebenza ngokujwayelekile (esihle noma esibi).
Inzwa ye-oxygen ephukile yenzani emotweni?
01 Ukwenyuka kokusetshenziswa kukaphethiloli
Ukulimala kwenzwa ye-oxygen yangemuva kuzoholela ekusetshenzisweni kukaphethiloli okwenyuka. Lokhu kungenxa yokuthi ukufakwa kwe-carbon kwinzwa ye-oxygen kungaholela ekuphumeni kwesignali okungavamile, okubuye kuthinte isilinganiso sokuxutshwa kwenjini, kuyenze ingalingani. Lapho isilinganiso sengxube yenjini singalingani, ukuze kugcinwe ukuvutha okuvamile, injini izolawula umjovo kaphethiloli omningi, okuholela ekuxubeni okukhulu, okubuye kwandise ukusetshenziswa kukaphethiloli. Ukwengeza, ngenxa yokwehluleka kwenzwa ye-oxygen, ulwazi olungalungile oludluliswayo lungabangela okuqukethwe kwe-oxygen ye-injini ukuba kube phezulu kakhulu, okuholela ekwandeni kokusetshenziswa kukaphethiloli. Ngakho-ke, uma inzwa ye-oxygen ilimele, kufanele ishintshwe kusenesikhathi ukuze kugwenywe ukwanda kokusetshenziswa kukaphethiloli.
02 Ukuphuma kokungcola kuyanda
Ukulimala kwenzwa ye-oxygen engemuva kuzoholela ekukhishweni kwegesi yemoto ngokweqile. Lokhu kungenxa yokuthi inzwa ye-post-oksijeni iyingxenye ebalulekile yokusebenza okujwayelekile kwesiguquli se-catalytic yezindlela ezintathu. Uma inzwa ye-post-oksijeni ihluleka, isiguquli se-catalytic sezindlela ezintathu asikwazi ukusebenza kahle, ukuze singakwazi ukuguqula ngokuphumelelayo izinto eziyingozi zibe izinto ezingenabungozi. Ngale ndlela, imoto izokhipha ukungcola okwengeziwe phakathi nenqubo yokushayela, okuholela ekukhishweni kwentuthu ephuma ngokweqile.
03 Sheshisa kancane
Ukulimala kwenzwa ye-oxygen yangemuva kuzobangela imoto ukuthi ihambe kancane. Lokhu kungenxa yokuthi inzwa ye-afteroxygen inesibopho sokuqapha inani lomoya-mpilo okhishwa injini futhi idlulisele lolu lwazi ohlelweni lokulawula ikhompuyutha yemoto. Lapho inzwa ye-afteroxygen yonakalisiwe, ikhompuyutha yemoto ayikwazi ukuthola ngokunembile le datha ebalulekile, ukuze injini ingakwazi ukulawulwa ngokunembile futhi ilungiswe. Lokhu kungaholela ekwehleni kokusebenza kahle kwenjini, okubuye kube nomthelela ekusebenzeni kwemoto ngesivinini, kuyenze ihambe kancane.
04 Isibani sokuhluleka kwenjini sizokhanya
Ngemuva kokuthi inzwa ye-oxygen ilimele, ukukhanya kokwehluleka kwenjini kuzokhanya. Lokhu kungenxa yokuthi inzwa ye-afteroxygen inesibopho sokuqapha okuqukethwe komoyampilo okhishwa injini futhi idlulisele idatha kusistimu yokulawula kagesi yemoto. Lapho inzwa ye-afteroxygen yonakalisiwe, ayikwazi ukunikeza le datha ngokunembile, okuholela ekutheni uhlelo lokulawula i-elekthronikhi alukwazi ukwahlulela ngokunembile isimo sokusebenza kwenjini. Kulokhu, uhlelo lokulawula lwe-elekthronikhi luzocabanga ukuthi kukhona ukwehluleka kwenjini okungenzeka, ngakho-ke ukukhanya kokwehluleka kwenjini ukuxwayisa umshayeli.
Sicela usishayele uma udinga imikhiqizo enjalo.
