txoj kev thov

1.Yog tias lub tshuab hluav taws xob tswj hluav taws xob siv lub tshuab hluav taws xob uas muaj cov pa oxygen sensor tsis ua haujlwm, xws li kev ua haujlwm tsis ruaj khov, tsis muaj zog acceleration, nce roj noj thiab tso pa ntau dhau, thiab tsis muaj lwm yam txhaum hauv cov khoom siv roj thiab hluav taws xob, nws Nws yog qhov zoo tshaj plaws uas muaj qee yam tsis ncaj ncees lawm nrog cov pa oxygen sensor thiab lwm yam circuits.

2.Lub tshuab hluav taws xob tswj ntawm cov cav feem ntau muaj kev kuaj xyuas tus kheej.Thaum cov pa oxygen sensor lossis lwm yam tsis ua haujlwm, lub khoos phis tawj yuav cia li sau cov ntsiab lus tsis raug, thiab cov neeg ua haujlwm saib xyuas tuaj yeem paub qhov teeb meem tsuas yog los ntawm kev nyeem cov lej txhaum nrog lub tshuab txiav tshwj xeeb.Tab sis yuav ua li cas yog tias tsis muaj cov cuab yeej tshwj xeeb?Ntawm no yog ob peb txoj hauv kev los tshawb xyuas qhov zoo ntawm oxygen sensor.

3.Yog tias nws xav tias qhov tsis ua haujlwm xws li tsis ruaj khov tsis ua haujlwm lossis kev nrawm nrawm yog tshwm sim los ntawm cov pa oxygen sensor, tsuas yog rub lub connector ntawm oxygen sensor thaum overhauling.Yog tias lub cav tsis ua haujlwm ploj mus, nws txhais tau hais tias cov pa oxygen sensor tau puas lawm thiab yuav tsum tau hloov.Yog tias lub cav tsis ua haujlwm tseem nyob, nrhiav qhov laj thawj los ntawm lwm qhov chaw.

4.Siv lub siab impedance voltmeter kuj tuaj yeem tshawb xyuas qhov zoo ntawm oxygen sensor.Txuas lub voltmeter nyob rau hauv parallel ntawm cov zis kawg ntawm cov pa sensor.Raws li ib txwm muaj, qhov voltage yuav tsum hloov ntawm 0-1V, thiab tus nqi nruab nrab yog li 500mV.Yog tias qhov tso zis hluav taws xob tseem tsis hloov mus ntev, nws qhia tau tias cov pa oxygen sensor tau puas lawm.

5.Qhov tseeb, cov pa oxygen sensor yog cov khoom siv ruaj khov heev, thiab nws tuaj yeem siv tau 3 xyoos lossis ntau dua yog tias cov roj zoo dhau tus qauv.Kev puas tsuaj txawv txav ntawm oxygen sensor feem ntau yog tshwm sim los ntawm cov ntsiab lus txhuas ntau dhau hauv cov roj.Cov neeg tsav tsheb uas tsav tsheb nruab nrog peb-txoj kev catalytic li yuav tsum tau them sai sai rau qhov no.
