1. Ukubekwa kwekhabhoni

Ngenxa yokutshiswa kakubi kwe-injini, iidiphozithi zekhabhoni zenziwa kumphezulu we-oxygen sensor, okanye iidiphozithi ezifana ne-oil stains okanye uthuli lungena kwi-oxygen sensor, eya kuthi ithintele okanye ivimbe umoya wangaphandle ukuba ungangeni kwi-oxygen sensor. isibonakaliso sokuphuma kwenzwa ye-oxygen engachanekanga, kwaye i-ECU ayikwazi ukulungisa umlinganiselo we-air-fuel ngexesha.Ukubekwa kwekhabhoni kubonakaliswa ikakhulu ekwandeni kokusetyenziswa kwepetroli kunye nokonyuka okucacileyo koxinzelelo lokukhupha.Ngeli xesha, ukuba intlenga isusiwe, iya kuphinda iqalise umsebenzi oqhelekileyo.

2. Ukuqhekeka kweCeramic ye-oxygen sensor

I-ceramic ye-oxygen sensor inzima kwaye i-brittle, kwaye inokuphuka kwaye ingaphumeleli ukuba ibethelwa ngento enzima okanye ihlanjwe ngomoya onamandla.Ngoko ke, kufuneka kuthathelwe ingqalelo ekhethekileyo xa kusingathwa, yaye iingxaki zifanele zitshintshwe ngexesha.

3. Ucingo lokumelana nesifudumezi lutshisiwe

Kwi-sensor ye-oksijeni efudumeleyo, ukuba ucingo lokumelana nokushisa luyacinywa, kunzima ukwenza inzwa ifikelele kubushushu obuqhelekileyo bokusebenza kwaye ilahlekelwe ngumsebenzi wayo.

4. Isiphaluka sangaphakathi se-oxygen sensor siphukile.

5.Ukuhlolwa kombala wembonakalo ye-oxygen sensor

Susa inzwa ye-oksijini kumbhobho wokukhupha, kwaye ukhangele ukuba i-vent hole kwi-sensor yezindlu ivaliwe kwaye i-corecemic core yonakalisiwe.Ukuba yonakele, buyisela inzwa ye-oxygen.

Impazamo inokugwetywa ngokujonga umbala wencam yenzwa ye-oxygen:

① Ingcebiso engwevu ekhanyayo: Lo ngumbala oqhelekileyo wenzwa yeoksijini;

② Ingcebiso emhlophe: Ibangelwa ukungcola kwe-silicon, kwaye inzwa ye-oxygen kufuneka itshintshwe ngeli xesha;

③ Ingcebiso emdaka: Ibangelwa lungcoliseko lwelothe.Ukuba inzulu, inzwa ye-oxygen nayo kufuneka itshintshwe;

④ Ingcebiso emnyama: Ibangelwa yidiphozithi yekhabhoni.Emva kokuba i-injini ye-carbon deposit iphoso isusiwe, idiphozithi ye-carbon kwi-sensor ye-oxygen inokususwa ngokuzenzekelayo.

I-sensor ye-oxygen ephambili ibandakanya intonga yokufudumala yokufudumala i-zirconia element.Intonga yokufudumala ilawulwa yikhompyutha (ECU).Xa ukungena komoya kuncinci (iqondo lokushisa liphantsi), i-current flow flow intonga yokufudumala ukutshisa inzwa, ukwenzela ukuba i-oxygen concentration ibonwe ngokuchanekileyo.

I-electrodes yePlatinum ihlelwe kumacala angaphakathi nangaphandle kwi-tube-shaped zirconium element (ZRO2 _ 2).Ukuze kukhuselwe i-electrode yeplatinum, icala langaphandle lemoto ligutyungelwe ngeekeramics, kwaye i-oksijini yoxinaniso kwicala langaphakathi liphezulu kune-atmosphere, ngelixa i-oksijini ye-oksijini kwicala langaphandle iphantsi kune-automobile exhaust gas concentration.
