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 lura da abubuwan da ke cikin iskar oxygen da ke fitar da iskar 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 ya gyara. lokacin allura bisa ga halin da ake ciki, ta yadda injin zai iya samun mafi kyawun haɗuwa na cakuda.
PS: Ana amfani da firikwensin pre-oxygen don gano taro na cakuda, kuma ana amfani da firikwensin bayan-oxygen don kwatanta ƙarfin sigina tare da firikwensin pre-oxygen don saka idanu da tasirin juyawa na mai sauya catalytic mai hanyoyi uku. .
Na biyu, matsayi na shigarwa
Na'urori masu auna iskar oxygen gabaɗaya suna zuwa ne bi-biyu, akwai biyu ko huɗu, waɗanda aka sanya a cikin bututun shaye-shaye mai mu'amalar catalytic kafin da bayansa.

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 abu mai kama da 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 layi, firikwensin oxygen mai faɗi, da sauransu.
PS: Ya dogara ne akan zazzafan nau'in zirconia oxygen tsawo tsawo.
