Iqhaza le-Post-Opygen Sensor.
Umsebenzi we-sensor ukunquma ukuthi ngabe kukhona i-oksijini engapheli enjini ephumayo ngemuva kokuhlangana, okungukuthi, okuqukethwe komoya-mpilo, bese uguqula okuqukethwe komoya-voygen ku-voltage loop factor ngokweqile ngenjongo; Qinisekisa ukuthi i-converter ye-catalytic enezindlela ezintathu inokuguqulwa okuphezulu kokungcola okuphezulu ku-hydrocarbon (HC), i-carbon monoxide (co) ne-nitrogen oxide (nox), futhi kwandise ukuguqulwa kanye nokuhlanzwa kokungcoliswa kokukhishwa.
Imisebenzi ye-sensor yile:
1, inzwa enkulu ye-oksijini ifaka phakathi into eshisa i-zirconia yenduku eshisayo, ukufudumeza induku ngu (Ecu) Ukulawulwa kwekhompyutha, lapho umoya wokuphumula uphansi (ukufundwa komoya kuphansi) ukugeleza kokushisa okufudumele kwe-oxygen okuhlushwa umoya-mpilo.
2. Imoto ifakwe izinzwa ezimbili ze-oksijini, eyodwa ngaphambi kwesiguquli sezindlela ezintathu ze-catalytic nenye ngemuva. Iqhaza langaphambili ukuthola isilinganiso samafutha e-Air-Fuel of injini ezimweni ezihlukile zokusebenza, futhi ikhompyutha ilungisa inani lokujova kaphethiloli futhi libala isikhathi sokulahla ngokuya ngesiginali. Into esemqoka ngemuva ukuthola umsebenzi we-converter yezindlela ezintathu ze-catalytic! Okungukuthi, izinga lokuguqulwa le-catalyst. Ngokuqhathanisa nedatha yenzwa ye-oxygen yangaphambili, kuyisisekelo esibalulekile sokuthola ukuthi ngabe i-converter yendlela emithathu isebenza ngokujwayelekile (okuhle noma kubi).
Ngabe inzwa ye-oxygen ephukile yenzani emotweni?
01 ukukhulisa uphethiloli
Ukulimala kwenzwa ye-oxygen yangemuva kuzoholela ekusetshenzisweni kwamafutha okwandayo. Lokhu kungenxa yokuthi imali yekhabhoni esenzweni ye-oksijini ingaholela ekuphumeni kwesiginali okungajwayelekile, okuthinta ukuxuba isilinganiso senjini, okwenza kungalinganiswa. Lapho isilinganiso sengxube yenjini singalinganiseli, ukuze silondoloze ukuhlanganiswa okujwayelekile, injini izolawula umjovo kaphethiloli, okuholela ekuhlolweni ngokweqile, okuvuselela ukusetshenziswa kwamafutha. Ngaphezu kwalokho, ngenxa yokwehluleka kwenzwa ye-oxygen, imininingwane engalungile edluliselwe ingadala ukuthi okuqukethwe kwe-oxygen yenjini kube phezulu kakhulu, okuholela phambili ekusetshenzisweni kwamafutha okwandayo. Ngakho-ke, uma inzwa ye-oksijini ilimele, kufanele ithathelwe indawo ngesikhathi ukugwema ukusetshenziswa kwamafutha okwengeziwe.
02 Ukukhishwa Kwe-Pollotant Kwenyuka
Ukulimala kwesehlakalo se-oxygen yangemuva kuzoholela ekuphumeni ngokweqile kwemoto. Lokhu kungenxa yokuthi inzwa ye-post-oxygen iyingxenye ebalulekile yokusebenza okujwayelekile kwe-converter yendlela emithathu ye-catalytic. Lapho inzwa ye-post-oxygen yehluleka, isiguquli esinezindlela ezintathu se-catalytic asikwazi ukusebenza kahle, ukuze singakwazi ukuguqula ngempumelelo izinto eziyingozi ezintweni ezingenangozi. Ngale ndlela, imoto izokhipha izimpondo eziningi ngesikhathi senqubo yokushayela, okuholela ekuphumeni ngokweqile kokukhipha.
03 shesha kancane kancane
Ukulimala kwesezwa ye-Oxygen yangemuva kuzodala ukuthi imoto yehlise ijubane. Lokhu kungenxa yokuthi inzwa ye-aclevelity inesibopho sokuqapha inani le-oksijini elikhishwe yinjini futhi lidlulisela lolu lwazi ohlelweni lokulawula amakhompyutha wemoto. Lapho inzwa ye-antoxgegen ilimele, ikhompyutha yemoto ayikwazi ukuthola kahle le datha elibucayi, ukuze injini ingakwazi ukulawulwa futhi ilungiswe. Lokhu kungaholela ekwehlisweni kokusebenza kahle kwenjini, okuthinta umsebenzi wokusheshisa kwemoto, okwenza kunciphise ijubane.
I-04 Ukuhluleka Kwezinjini Ukukhanya Kuzovulwa
Ngemuva kokuthi inzwa ye-oksijini ilimele, ukukhanya kwe-enjini kuzokhanya. Lokhu kungenxa yokuthi inzwa ye-aflexgen ibhekele ukubheka okuqukethwe kwe-oksijini okukhishwe yinjini futhi kudlulisela idatha ohlelweni lwemoto yokulawula i-elektroniki. Lapho inzwa ye-anyoxgen ilimele, ayikwazi ukunikeza ngokunembile le mininingwane, okuholela ohlelweni lokulawula ngogesi alukwazi ukwahlulela ngokunembile isimo esisebenzayo senjini. Kulokhu, uhlelo lokulawula ngogesi luzocabanga ukuthi kukhona ukwehluleka kwenjini okungenzeka, ngakho-ke injini yehluleka ukukhanya ukuqaphela umshayeli.
