1. Cov zaub mov zais pa

Vim tias cov kev sib txuas tsis zoo ntawm lub cav, cov pa roj carbon cia yog tsim nyob rau hauv cov pa roj oxygen los yog cov ECU tsis tuaj yeem kho cov pa hluav taws xob sib piv. Cov pa roj carbon depupition feem ntau yog ua kom pom kev nce hauv kev siv roj thiab cov khoom pom tseeb nce ntawm kev tso tawm kev pom kev. Nyob rau lub sijhawm no, yog hais tias kev txiav tawm ntawm kev tshem tawm, nws yuav rov ua haujlwm ib txwm muaj.

2. Ceramic Frandmentation ntawm Cov Pa Sensor

Cov ceramic ntawm cov pa yeeb tshuaj yeeb yog qhov nyuaj thiab tawg, thiab nws yuav tawg yog tias nws tau khob qhov khoom tawv lossis ntxuav nrog cua khov kho. Yog li, kev saib xyuas tshwj xeeb yuav tsum tau coj thaum tuav, thiab teeb meem yuav tsum tau hloov nyob rau lub sijhawm.

3. Lub rhaub dej tawm xaim hluav taws xob yog hlawv tawm

Rau cov pa roj ua pa tawm, yog hais tias cov kav dej kub ua haujlwm hlau yog ablated, nws yog qhov nyuaj ua kom lub sensor mus ua haujlwm ib txwm ua haujlwm thiab poob nws txoj haujlwm.

4. Sab hauv lub voj voog ntawm cov pa yeeb ntxig tawg yog tawg.

5. kev khaws cov tsos xim ntawm cov pa sensor

Tshem tawm cov pa sensor los ntawm cov pa yeeb nkab, thiab tshuaj xyuas seb puas muaj qhov kub ntawm lub tsev ua haujlwm thaiv thiab cov tub kab ceramic raug puas ntsoog. Yog tias nws raug puas, hloov cov pa oxygen.

Qhov txhaum kuj tseem tuaj yeem raug txiav txim los ntawm kev saib cov xim ntawm qhov taub ntawm cov pa sensor:

① Cov Lus Qhia Grey: Qhov no yog cov xim ib txwm muaj cov pa sensor;

② Cov Tswv Yim Dawb: Nws yog tshwm sim los ntawm silicon viicutor, thiab cov pa sensor yuav tsum tau hloov lub sijhawm no;

③ Cov lus qhia xim av: Nws yog tshwm sim los ntawm kev ua qias tuaj. Yog tias nws yog mob hnyav, cov pa ntsuas pa yuav tsum tau hloov;

④ Cov Tswv Yim Dub: Nws tshwm sim los ntawm cov pa roj carbon tso nyiaj. Tom qab lub cav hluav taws ua haujlwm tso tawm yog muab tshem tawm, cov pa tso nyiaj tso rau ntawm cov pa oxygen tuaj yeem tshem tawm tau.

Cov pa oxygen tseem ceeb suav nrog cov pas ntoo cua sov rau cua sov lub zirconia keeb. Cov pas dej cua kub yog tswj los ntawm lub khoos phis tawm (ECU). Thaum cov huab cua nkag tau me me (lub tso cua sov yog tsawg), qhov tam sim no ntws mus rau cua sov lub sensor, kom cov pa oxygen tuaj yeem raug kuaj tau.

Platinum cov ntawv hluav taws xob tau npaj rau sab hauv thiab sab nraud ntawm cov raj-puab zirconium keeb (ZRO2). Txhawm rau tiv thaiv cov platinum electrodes, sab nraud ntawm lub cev muaj zog yog siab dua cov huab cua, thaum cov pa oxygen nyob sab nraud yog qis dua lub tsheb tso pa tawm pa roj cua.
