Kungani kufanele sifunde isibonakaliso se-clutter kwi-waveform yenzwa ye-oxygen?

Lokhu kungenxa yokuthi imfuhlumfuhlu ingabangelwa ukusebenza kahle kokuvutha okuphansi. Uma nje uhlelo lwe-Up-Flow lungekho esimweni esifanele sokusebenza, i-catalyst ayikwazi ukuvivinywa ngokunembile. Imfucumfucu ye-waveform ye-oxygen sensor ingaxwayisa ukwehla kokusebenza kwe-cylinder ngayinye yenjini. Ngalesi sikhathi, ukuxilongwa kwegesi yokuphelelwa yigesi kubaluleke kakhulu. Ngoba ingathola ukuthi ukusebenza kahle kokuguquguquka kwe-catalyst kuyancipha futhi ukusebenza kwama-cylinder athile kuyancipha. Amasiginali we-Clutter abuye avimbele ukusebenza okujwayelekile kwesilawuli sohlelo lokulawula impendulo yamafutha (uhlelo lokuphendula ku-Injini Yokulawula I-Curs). "Isilawuli sohlelo lokulawula uphethiloli" sisho uhlelo lokusebenza lwesoftware (olubizwa ngokuthi "isilawuli sempendulo"), okuwuhlelo oluthola umjovo we-voltage lwenzwa ye-oxygen futhi lubala umjovo ofanele wamafutha noma umyalo wokulawula ukuxuba. Ngokuvamile, uhlelo lokulawulwa kwempendulo alwenzelwe ukuqeda ngempumelelo imvamisa yezinzwa ze-oksijini ezenziwe ngenxa yokusebenza kohlelo olungajwayelekile kanye nemiyalo yokulawula uphethiloli. Isigcawu sokuguquguquka imvamisa yokuguquguquka kwamava Kunemiphumela eminingana lapha. Okokuqala, lapho ukunemba kokusebenza komlawuli wempendulo kuyathinteka, isilinganiso sengxube kaphethiloli sizodlula iwindi le-catalyst, elizothinta ukusebenza kahle kwe-converter kanye nokuphuma kokukhipha amandla. Okwesibili, ukusebenza kwenjini nakho kuzothinteka. I-Clutter ingaba inkomba enqumayo yokuthi igesi engaphandle kokulawulwa ingena nge-catalyst. Kuvame ukutholakala ukuthi lapho i-clutter ekhona, igesi eqeda amandla okufaka i-catalyst ayinaso isilinganiso esifanele somoya. Kubaluleke kakhulu ukuqonda imfuhlumfuhlu nge-waveform yenzwa ye-oxygen yokulungiswa nokuxilongwa kokuphuma kwegesi. Kwezinye izimo, i-clutter iyisibonakaliso esisobala sokuthi ukusebenza kahle kokuguqulwa kwe-catalytic kuncishisiwe, bese kuthi ukukhishwa okuqeda amandla kudlula izinga. Ngaphezu kwalokho, incazelo ye-clutter ku-waveform ye-oxygen sensor iyithuluzi elibalulekile ekutholweni kokusebenza kwenjini noma ikhono lokushayela. I-Clutter iyisibonakaliso sokungalingani ekusebenzeni kahle kwesilinda kwesinye. Ukuchazwa kanye nokuqonda kwe-clutter ku-waveform transmitter ka-oxygen kubalulekile kakhulu ekusebenziseni okusebenzayo kokulungiswa kokulungiswa nokuqinisekiswa kwe-oksijini. I-Clutter on the waveform ye-avegen sensor ikhombisa ukuthi igesi ephumayo ishintsha kusuka kusilinda esisodwa kwesinye isilinda esingenakulinganiswa Izinzwa eziningi ze-oksijini zingasondla ngokushesha emuva kokuphambuka kwamandla kagesi okukhiqizwa inqubo ngayinye yokuhlanganisa lapho zisebenza ngokujwayelekile. Uma kukhulu umkhawulo wesiginali we-clutter, kukhulu umehluko wokwakheka komoya-mpilo olinganiswe kwinqubo ngayinye yokuhlanganisa. I-clutter ebonwe ngaphansi kwezindlela ezahlukahlukene zokushayela ayigcini nje ngokuthola imbangela yokwehluleka kokuhlolwa kwegesi okuqhubekayo nokuphenya ngegesi, kepha nesisekelo sokwahlulela esisebenzayo sokuthola ukuxilongwa kwegesi. I-oxygen sensor sensor clutter eyakha i-wavelform eyodwa kuya ku-paralform eyodwa nge-Peak Burr ye-BC kwimodi yokusheshisa iyisiginali ebaluleke kakhulu yokuxilonga, ngoba kusho ukuthi ukulahlwa kuzokwehluleka umthwalo ngaphansi komthwalo. Ngokuvamile, kukhudlwana amplitude ye-clutter. Kukhona izinzwa eziningi ze-oksijini kugesi ophelelwe yisikhathi, ngakho-ke imfuhlumfuhlu iyinkomba yokuthi okuqukethwe okujwayelekile komoya-mpilo wegesi yempendulo efaka ukwanda kwe-catalyst ngaphambi kokuqothuka kwe-oxygent angeke kuncishiswe imvelo ecebile yomoya (umxube we-loend). Ukufingqa, kuyaziwa ukuthi isibonakaliso se-clutter ku-waveform sensor ye-oxygen ngohlelo olujwayelekile lwempendulo evamile alunalo ithonya elisobala ekusebenzeni kwegesi noma nge-injini. Inani elincane le-futter linganakwa, kanti inani elikhulu le-clutter libalulekile. Lokhu kukhombisa nje ukuthi ukuxilongwa kungubuciko. Ukuze ufunde ukwahlulela ukuthi yini imfuhlumfuhlu ejwayelekile nokuthi yini okungadingi ukukwenza, futhi uthisha omuhle kakhulu unesipiliyoni. Indlela engcono kakhulu yokufunda ukubheka i-waveform ye-avelgen sensor kusuka ekubukeni imayela elihlukile nezinhlobo ezahlukene zezimoto. Ukuqonda okuyisidina okujwayelekile nokuthi yini imfuhlumfuhlu engajwayelekile ibaluleke kakhulu ekusebenzeni okusebenzayo kokuphuma kokuphuma nokushayela ngekhono lokushayela, futhi kufanelekile ukuthatha isikhathi sokufunda. Ngezinhlelo ezijwayelekile, i-waveform yesoftware ibalulekile ngokuphelele. Ukuba ne-wave yethebula le-oksijini elilawulwa ngalolo hlelo lungacaciswa kunganquma ukuthi hlobo luni lwe-clutter luvumelekile futhi lujwayelekile, nokuthi hlobo luni lwemfucuza okufanele lunake. Izindlela zokuhlanzeka okuhle yilezi: Uma ukusebenza kwenjini kulungile, akufanele kube nokuvuza kwe-vacuum, kanye ne-hydrocarbon (hc) compound kanye nokuqukethwe komoya-mpilo kugesi ophelelwe yisikhathi kujwayelekile. Kule ngxenye yokuhlolwa, imininingwane eminingi ngangokunokwenzeka izonikezwa ukuze uqonde ukuthi kunesikhathi esanele nendawo yokumboza zonke izihloko eziphathelene nalokhu kulokhu kuqeqesho.
