Khoom taw qhia
1. Cov pa roj carbon deposition
Vim yog qhov tsis zoo ntawm lub cav, cov pa roj carbon deposits yog tsim nyob rau saum npoo ntawm cov pa oxygen sensor, los yog cov deposits xws li cov roj stains los yog plua plav nkag mus rau oxygen sensor, uas yuav cuam tshuam los yog thaiv cov huab cua sab nraud los ntawm kev nkag mus rau cov pa oxygen sensor, ua rau cov pa oxygen sensor. tso zis teeb liab ntawm cov pa sensor tsis raug, thiab ECU tsis tuaj yeem kho cov huab cua-roj piv rau lub sijhawm. Cov pa roj carbon deposition feem ntau tshwm sim nyob rau hauv qhov nce ntawm roj noj thiab pom tseeb nce emission concentration. Lub sijhawm no, yog tias cov av tshem tawm, nws yuav rov ua haujlwm li qub.
2. Ceramic fragmentation ntawm oxygen sensor
Lub ceramic ntawm oxygen sensor yog ib qho nyuaj thiab nkig, thiab nws yuav tawg thiab ua tsis tiav yog tias nws yog khob nrog ib qho khoom tawv los yog ntxuav nrog cov cua muaj zog. Yog li ntawd, yuav tsum tau saib xyuas tshwj xeeb thaum tuav, thiab cov teeb meem yuav tsum tau hloov raws sijhawm.
3. Lub cua sov ua haujlwm hlau yog hlawv tawm
Rau cov cua sov oxygen sensor, yog tias lub tshuab cua sov ua kom tsis muaj zog hlau yog ablated, nws nyuaj rau ua kom lub sensor ncav cuag qhov kub thiab txias ua haujlwm thiab poob nws txoj haujlwm.
4. Sab hauv Circuit Court ntawm oxygen sensor tawg.
5.Kev tshuaj xyuas qhov tsos xim ntawm oxygen sensor
Tshem tawm cov pa oxygen sensor los ntawm cov yeeb nkab tso tawm, thiab xyuas seb lub qhov cua ntawm lub sensor vaj tse puas raug thaiv thiab cov tub ntxhais ceramic puas puas. Yog tias nws puas lawm, hloov lub ntsuas pa oxygen.
Qhov txhaum kuj tuaj yeem raug txiav txim los ntawm kev soj ntsuam cov xim ntawm lub ntsis ntawm cov pa oxygen sensor:
① Lub teeb grey ntsis: Qhov no yog xim ib txwm muaj oxygen sensor;
② Cov lus qhia dawb: Nws yog tshwm sim los ntawm cov pa phem silicon, thiab cov pa oxygen sensor yuav tsum tau hloov lub sijhawm no;
③ Lub taub hau xim av: Nws yog tshwm sim los ntawm cov hmoov txhuas. Yog tias nws loj heev, lub ntsuas pa oxygen kuj yuav tsum tau hloov pauv;
④ Dub hau: Nws yog tshwm sim los ntawm cov pa roj carbon deposits. Tom qab lub cav carbon deposit txhaum raug tshem tawm, cov pa roj carbon deposit ntawm cov pa sensor tuaj yeem raug tshem tawm.
Cov pa oxygen sensor tseem ceeb suav nrog lub pas nrig cua sov rau cua sov lub caij zirconia. Cov pas ntsuas kub yog tswj los ntawm lub computer (ECU). Thaum cov cua nkag me me (qhov tso cua sov tsawg), qhov tam sim no ntws mus rau lub pas nrig cua sov kom sov lub sensor, kom cov pa oxygen concentration yuav raug kuaj pom tseeb.
Platinum electrodes yog teem rau sab hauv thiab sab nraud ntawm lub raj zoo li zirconium caij (ZRO2 _ 2). Txhawm rau tiv thaiv platinum electrodes, sab nraud ntawm lub cev muaj zog yog them nrog ceramics, thiab cov pa oxygen concentration nyob rau sab hauv yog siab dua li cov cua, thaum cov pa oxygen concentration nyob rau sab nraud yog qis dua lub tsheb tso pa roj concentration.
