Kungani kufanele sitadishe isignali ye-clutter ku-waveform yenzwa ye-oxygen?

Lokhu kungenxa yokuthi imfuhlumfuhlu ingase ibangwe ukusebenza kahle okuphansi kokuvutha. Uma nje isistimu yokugeleza kwamanzi ingekho esimweni esilungile sokusebenza, i-catalyst ayikwazi ukuhlolwa ngokunembile. Imfuhlumfuhlu ye-waveform yenzwa yomoya-mpilo ingaxwayisa ukwehla kokusebenza kwesilinda senjini ngayinye. Ngalesi sikhathi, ukuxilongwa kwegesi ephumayo kubaluleke kakhulu. Ngoba ingathola ukuthi ukusebenza kahle kokuguqulwa kwe-catalyst kuncipha futhi ukusebenza kwamasilinda ngamanye kuyehla. Amasignali we-clutter aphinde avimbele ukusebenza okuvamile kwesilawuli sesistimu yokulawula impendulo kaphethiloli (uhlelo lwempendulo kukhompyutha yokulawula injini luyasebenza). "Isilawuli sesistimu yokulawula impendulo kaphethiloli" sibhekisela ohlelweni lwesofthiwe olusebenzayo (olubizwa ngokuthi "isilawuli sempendulo"), okuwuhlelo oluthola isignali ye-voltage yenzwa ye-oxygen futhi lubala umjovo osheshayo wamafutha noma umyalo wokulawula ingxubevange. Ngokuvamile, uhlelo lwesilawuli sempendulo aluklanyelwe ukuqeda ngempumelelo imvamisa yamasiginali enzwa ye-oxygen akhiqizwa ngenxa yokusebenza okungavamile kwesistimu nemiyalo yokulawula uphethiloli. Isiginali yokuguquguquka kwemvamisa ephezulu yesiphithiphithi ingenza isilawuli sempendulo silahlekelwe ukunemba kokulawula noma "isigqi sempendulo". Kunemiphumela eminingana lapha. Okokuqala, lapho ukunemba kokusebenza kwesilawuli sempendulo kuthinteka, isilinganiso sengxube kaphethiloli sizodlula iwindi le-catalyst, elizothinta ukusebenza kahle kokusebenza kwesiguquli kanye nokukhishwa kwe-exhaust. Okwesibili, ukusebenza kwenjini nakho kuzothinteka. Imfuhlumfuhlu ingaba inkomba enqumayo yokuthi igesi ephuma ngaphandle kokulawula ingena ku-catalyst. Kuvame ukutholakala ukuthi uma imfuhlumfuhlu ikhona, igesi ephumayo engena ku-catalyst ayinayo isilinganiso esifanele samafutha omoya. Kubaluleke kakhulu ukuqonda i-clutter ku-waveform yenzwa ye-oxygen ukuze kulungiswe futhi kuhlolwe ukukhishwa kwegesi ephumayo. Kwezinye izimo, imfuhlumfuhlu iyisiginali esobala yokuthi ukusebenza kahle kokuguqulwa kwe-catalytic kuncishisiwe, bese ukuphuma kwe-exhaust kudlule izinga. Ngaphezu kwalokho, incazelo ye-clutter ku-waveform yenzwa ye-oxygen iyithuluzi elibalulekile lokuxilongwa kokusebenza kwenjini noma ikhono lokushayela. Imfuhlumfuhlu iyinkomba yokungalingani ekusebenzeni kahle komlilo kusuka kusilinda esisodwa kuya kwesinye. Incazelo kanye nokuqonda kwe-clutter ku-waveform ye-oxygen transmitter nayo ibaluleke kakhulu ekusetshenzisweni ngempumelelo kwesignali yenzwa ye-oxygen nokuqinisekisa. Imfuhlumfuhlu ku-waveform yenzwa ye-oxygen ibonisa ukuthi igesi yokukhipha iyashintsha isuka ku-cylinder eyodwa iye kwesinye engalingani, noma ikakhulukazi, okuqukethwe okuphezulu kwe-oxygen akutholakali ezinqubweni zokuvutha ngakunye. Izinzwa eziningi zokwenza umoya-mpilo zikwazi ukubuyisela ngokushesha ukuchezuka kwe-voltage okukhiqizwa inqubo ngayinye yokuvutha lapho zisebenza ngokujwayelekile. Lapho umkhawulo wesignali we-clutter umkhulu, umehluko omkhulu wokwakheka komoyampilo olinganiswa ngenqubo ngayinye yokuvutha. Imfuhlumfuhlu ebonakala ngaphansi kwezindlela zokushayela ezihlukene ayibalulekile nje kuphela ukuze kutholwe imbangela eyinhloko yokuhluleka kokuhlolwa kwegesi ekhipha umoya ephumayo ehlala njalo nesikhashana, kodwa futhi nesisekelo sokwahlulela esisebenzayo sokuxilongwa kokushayeleka. I-clutter yesignali yenzwa ye-oxygen eyenza i-one-to-one exhaust waveform ene-peak burr ye-BC kumodi yokusheshisa iyisiginali ebaluleke kakhulu yokuxilonga, ngoba kusho ukuthi ukuthungela kuzohluleka ngaphansi komthwalo. Ngokuvamile, i-amplitude enkulu ye-clutter. Kunezinzwa ze-oksijini ezengeziwe ku-exhaust gas, ngakho-ke i-clutter iyinkomba yokuthi isilinganiso se-oksijini yegesi yempendulo engena ku-catalyst iyanda ngaphambi kokukhipha umoya, futhi i-nitrogen oxide ku-catalyst ayikwazi ukuncishiswa (ngamakhemikhali) ku-oxygen ecebile. imvelo (ingxube engenamafutha). Ukufingqa, kuyaziwa ukuthi isignali ye-clutter ku-waveform yenzwa ye-oxygen enesistimu yempendulo evamile ayinalo ithonya elisobala ekusebenzeni kwegesi ekhishwayo noma injini. Inani elincane le-clutter lingashaywa indiva, kuyilapho inani elikhulu le-clutter libalulekile. Lokhu kukhombisa nje ukuthi ukuxilongwa kuwubuciko. Ukufunda ukwahlulela ukuthi yikuphi okuyimfuhlumfuhlu okuvamile nokuthi yini engekho kudinga ukuzijwayeza, futhi uthisha ongcono kakhulu isipiliyoni. Indlela engcono kakhulu yokufunda ukubuka i-waveform yenzwa ye-oxygen kusukela ekubukeni amakhilomitha ahlukene nezinhlobo ezahlukene zezimoto. Ukuqonda ukuthi yini imfuhlumfuhlu evamile nokuthi iyini imfuhlumfuhlu engavamile kubaluleke kakhulu ekulungiseni okusebenzayo kokukhipha umoya kanye nokuxilongwa kwekhono lokushayela, futhi kuwufanele ukuthatha isikhathi sokufunda. Kuzinhlelo ezijwayelekile, i-waveform yesoftware ibaluleke kakhulu. Ukuba nereferensi yenzwa ye-oxygen waveform yesistimu elawulwayo kunganquma ukuthi hlobo luni lwe-clutter oluvumelekile futhi olujwayelekile, nokuthi hlobo luni lwemfuhlumfuhlu okufanele inakwe. Imibandela yemfuhlumfuhlu enhle yilena: uma ukusebenza kwenjini kukuhle, akumele kube khona ukuvuza kwe-vacuum, futhi izinhlanganisela ze-hydrocarbon (HC) nokuqukethwe komoyampilo ku-exhaust gas kuvamile. Kule ngxenye yocwaningo, kuzonikezwa ulwazi oluningi ngangokunokwenzeka ukuze kuqondwe ukuthi kunesikhathi esanele nendawo yokuhlanganisa zonke izihloko ezimayelana nalokhu kulokhu kuqeqeshwa.
