Sanin asali na firikwensin iskar oxygen da ganowa da kiyayewa, gaba ɗaya na gaya muku!
A yau za mu yi magana game da na'urori masu auna iskar oxygen.
Na farko, rawar oxygen firikwensin
Ana amfani da firikwensin iskar oxygen don saka idanu akan abubuwan da ke cikin iskar gas na injin bayan konewa, kuma yana canza abun cikin iskar oxygen zuwa siginar wutar lantarki zuwa ECU, wanda ke yin nazari tare da tantance adadin cakuda daidai da siginar, kuma yana daidaita lokacin allura daidai da yanayin, ta yadda injin zai sami mafi kyawun taro na cakuda.
PS: Ana amfani da firikwensin pre-oxygen don gano taro na cakuduwar, kuma firikwensin bayan-oxygen ana amfani da shi ne don kwatanta ƙarfin siginar da firikwensin iskar oxygen don lura da tasirin jujjuyawar na'urar catalytic ta hanyoyi uku.
Na biyu, matsayi na shigarwa
Na'urori masu auna sigina gabaɗaya suna zuwa ne bi-biyu, akwai biyu ko huɗu, waɗanda aka sanya a cikin bututun shaye-shaye mai mu'amalar catalytic mai hanya uku kafin da bayan.

Gajartawar Ingilishi: O2, O2S, HO2S
Na hudu, rarraba tsarin
Akwai hanyoyi da yawa don rarraba firikwensin oxygen, PS: na'urori masu auna iskar oxygen na yanzu suna zafi, kuma layi na farko da na biyu sune na'urori masu zafi na oxygen. Bugu da ƙari, ana kuma raba firikwensin oxygen zuwa sama (gaba) na'urar firikwensin oxygen da ƙasa (baya) na'urar firikwensin oxygen gwargwadon matsayi (ko aiki). Motoci da yawa yanzu suna sanye da na'urori masu auna iskar oxygen mai waya 5 da waya 6.
Anan, muna magana ne akan firikwensin oxygen guda uku:
Titanium oxide Nau'in:
Wannan firikwensin yana amfani da siminconductor abu titanium dioxide, kuma ƙimar juriyarsa ya dogara da isashshen iskar oxygen a cikin mahalli da ke kewaye da kayan semiconductor titanium dioxide.
Lokacin da akwai ƙarin oxygen a kusa, juriya na titanium dioxide TiO2 yana ƙaruwa. Akasin haka, lokacin da iskar oxygen da ke kewaye da shi ya yi ƙanƙanta, juriyar titanium dioxide TiO2 yana raguwa, don haka juriyar firikwensin iskar oxygen na titanium dioxide yana canzawa sosai kusa da ƙimar iskar man fetur, kuma ƙarfin fitarwa shima yana canzawa sosai.
Lura: Lokacin da zafin jiki ya yi ƙasa sosai, ƙimar juriya na titanium dioxide zai canza zuwa rashin iyaka, ta yadda ƙarfin firikwensin firikwensin ya kusan kusan sifili.
Zirconia irin:
Abubuwan ciki da na waje na bututun zirconia an lullube su da Layer na platinum. A karkashin wasu yanayi (high zafin jiki da platinum catalysis), m bambanci yana samuwa ta hanyar maida hankali bambancin oxygen a bangarorin biyu na zirconia.
Broadband oxygen Sensor:
Ana kuma kiransa firikwensin rabon iskar man fetur, firikwensin oxygen na broadband, firikwensin oxygen na layin, firikwensin iskar oxygen mai faɗi, da sauransu.
PS: Ya dogara ne akan zazzafan nau'in zirconia mai zafi na firikwensin oxygen tsawo.
