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. isignali yemveliso ye-oxygen sensor ayichanekanga, 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, kwaye 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.
