Oxygen inzwa: idivayisi kanye nokuqokwa

Inzwa lambda uphenyo (noma amazwi ngenye abashayeli, probe lambda) - indlela ukuthi unesibopho okuhlushwa isilinganiso amafutha kanye lomoya ingxube uphethiloli emoyeni ngesikhathi sokulungiselela yayo futhi Kondliwa iziteshi uphethiloli cylinder. On the ubuqiniso ubufakazi idivayisi kuncike Imininingwane petrol, amandla kanye namandla okubakhona imoto. Eqinisweni, ukubaluleka inzwa ifaniswe ne carburetor futhi injector, kusukela kokubili abahileleke ngokuqondile ekulungiseleleni ingxube nophethiloli. Esihlokweni lanamuhla sifunda ukuthi enze uphenyo lambda enjalo, ukuthi isebenza kanjani futhi ukuthi kushiwoni.

kudivayisi

Isisekelo (ilungu ikakhulu ezisebenza), inzwa sisetshenziselwa izinto ukungena nakwamanye amazwe Ceramic okuyinto kuveza zirconium dioxide. Umklamo kakhulu efanayo kule divayisi kuhilela izingxenye ezilandelayo:

• steel bezinhlamvu;
• cuff wire;
• Ceramic yisivikelo;
• xhumana Ukushisa wesifunda;
• Izintambo zikagesi ezisobala;
• O-ring;
• Zirconia ithiphu Ceramic;
• induku nge intambo Kuvunguza;
• isihlangu elingaphakathi umgodi esikhethekile amagesi qeda;
• isihlangu yangaphandle nge kunesikhala for emoyeni asemkhathini;
• ngalendoda uphawu lukagesi.

is it Umiswe kuphi?

Ngokuvamile i-probe lambda (VAZ-2110 ngokukhethekile) elise ohlelweni qeda, ngaphandle kwe-ezininginingi qeda. Futhi qaphela ukuthi ezinye izimoto kungenzeka kumadivayisi amabili anjalo. Omunye wabo angagula ngilungele umfula we kulethe, kanti owesibili - emva kwalo. Okuqasha iphenya ezimbili lambda kakhulu ukupheka kahle futhi ukunemba ingxube uphethiloli emoyeni kwandisa okwengeziwe ukuze supply yayo kuya yangaphakathi omlilo injini omlilo ekamelweni.

Umgomo we operation

I-algorithm zale divayisi kusekelwe izakhiwo oxide zirconium. Ngakho-ke, siqhutshwa ezingeni lokushisa okungenani 350 degrees Celsius. Kwezinye izimo, ukuze ukusheshisa Ukushisa inqubo, nokusetshenziswa ekhethekile heater. Lonke Umgomo we probe lambda zingahlukaniswa izigaba eziningana:

1. Kuchithwe qeda amagesi udabula kulethe kanye ipayipi qeda. Noma kunjalo, flow emhlabeni ebusweni zokusebenza inzwa lambda Uphenyo esemgwaqweni umfula we kulethe.
2. Ngaphezu kwalokho, kule divayisi ihlaziya ezingeni O2 ku igesi qeda kanye ufanisa idatha nezinga emkhathini.
3. Phakathi nomsebenzi we-inzwa ukhiqiza ezingaba umehluko whereupon mshini uthumela emfushane isignali kagesi ECU injini.
4. Ngemva kwalokho, ikhompyutha IZINHLELO idatha bese ukhulula isignali ukuze inombolo letsite amadivayisi, kanjalo ngokulungisa ekusebenzeni actuators.

Kufanele kuqashelwe ukuthi uma ukushoda oxygen uhlelo, okungukuthi, ingxube emoyeni-fuel, imikhiqizo amandla omlilo kungukuthi oxidized ngokugcwele. Esimweni esinjalo, imoto iqala ukulahlekelwa umfutho walo nokwanda petrol kwenzeka (ingxube mafutha kwakheka ekamelweni). Uma emoyeni ohlelweni kakhulu, lokhu kuholela noqhekeko ongaphelele oxide nitric, okuyilona elisebenzayo futhi akuyona indlela engcono ibonakala ukusebenza yenjini.
