Ruzivo rwekutanga rwesensa yeokisijeni uye kuona nekugadzirisa, zvese zvinokuudza panguva imwe chete!
Nhasi tichataura nezve sensors dzeoxygen.
Chekutanga, basa re sensor yeokisijeni
Chinoongorora okisijeni chinoshandiswa zvakanyanya kutarisa huwandu hweokisijeni mugasi rinobuda muinjini mushure mekutsva, uye chinoshandura huwandu hweokisijeni kuita chiratidzo chemagetsi kuenda kuECU, icho chinoongorora nekuona huwandu hwemusanganiswa zvichienderana nechiratidzo, uye chinogadzirisa nguva yekupinza zvichienderana nemamiriro ezvinhu, kuitira kuti injini iwane huwandu hwakanakisa hwemusanganiswa.
PS: Sensor ye pre-oxygen inonyanya kushandiswa kuona huwandu hwemusanganiswa, uye sensor ye post-oxygen inonyanya kushandiswa kuenzanisa voltage yesignal ne sensor ye pre-oxygen kuti iongorore mhedzisiro yekushandura kwe three-way catalytic converter.
Chechipiri, nzvimbo yekugadzwa
Ma sensor eokisijeni anowanzouya ari maviri maviri, maviri kana mana, akaiswa mu exhaust pipe three-way catalytic converter pamberi uye mushure.

Chidimbu cheChirungu: O2, O2S, HO2S
Chechina, kupatsanura chimiro
Kune nzira dzakawanda dzekuisa ma sensor e oxygen mumapoka, PS: ma sensor e oxygen aripo anodziiswa, uye mitsara yekutanga neyechipiri ma sensor e oxygen asina kudziiswa. Pamusoro pezvo, sensor ye oxygen yakakamurwawo kuita sensor ye oxygen yepamusoro (yepamberi) uye sensor ye oxygen iri pasi (yekumashure) zvichienderana nenzvimbo (kana basa). Mota dzakawanda ikozvino dzakashongedzwa nema sensor e oxygen e 5-waya ne 6-waya.
Pano, tinonyanya kutaura nezve sensors nhatu dzeokisijeni:
Titanium oxide rudzi:
Sensor iyi inoshandisa titanium dioxide inoshandiswa ne semiconductor material, uye kukosha kwayo kwekudzivirira kunoenderana nehuwandu hweokisijeni munzvimbo yakatenderedza titanium dioxide inoshandiswa ne semiconductor material.
Kana paine okisijeni yakawanda pedyo, kuramba kwetitanium dioxide TiO2 kunowedzera. Kusiyana neizvi, kana okisijeni yakapoteredza iri diki, kuramba kwetitanium dioxide TiO2 kunoderera, saka kuramba kwetitanium dioxide oxygen sensor kunochinja zvakanyanya pedyo nechiyero chemhepo-fuel chepfungwa, uye voltage inobuda inochinjawo zvakanyanya.
Cherechedza: Kana tembiricha yadzikira zvakanyanya, simba rekudzivirira titanium dioxide rinoshanduka kuita risingaperi, zvekuti simba remagetsi rinobuda mu sensor rinosvika zero.
Rudzi rweZirconia:
Nzvimbo dzemukati nedzekunze dzemachubhu ezirconia dzakaputirwa neplatinum. Mune mamwe mamiriro ezvinhu (kupisa kwakanyanya uye platinum catalysis), musiyano unokonzerwa nekusiyana kwehuwandu hweokisijeni kumativi ese ezirconia.
Chinoongorora okisijeni yeBroadband:
Inonziwo sensor yehuwandu hwemhepo-mafuta, sensor ye okisijeni ye broadband, sensor ye okisijeni yakatsetseka, sensor ye okisijeni yakafara, nezvimwewo.
PS: Yakavakirwa pakuwedzera kwe sensor yeoxygen yerudzi rwezirconia.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemota zveMG&MAUXS zvinogamuchirwa kutenga.
