Cov O2 sensor tau teeb tsa nyob rau hauv qhov tso pa tawm los saib xyuas ntau npaum li cas tsis kub hnyiab oxygen yog nyob rau hauv cov pa raws li cov pa tawm ntawm lub cav. Saib xyuas oxygen qib hauv cov pa tawm yog ib txoj hauv kev los ntsuas qhov sib xyaw roj. Nws qhia rau lub khoos phis tawj yog tias cov roj sib tov yog hlawv nplua nuj (tsawg dua oxygen ) los yog lean (ntau dua oxygen ).

Hauv qhov no, lub o2 sensor ua haujlwm li cas?

Cov pa oxygen sensors ua haujlwm los ntawm kev tsim lawv tus kheej voltage thaum lawv kub (kwv yees li 600 ° F). Hauv qhov kawg ntawm qhov pa sensor uas ntsaws rau hauv cov pa tawm manifold yog zirconium ceramic noob. Thaum cov huab cua / roj sib tov nyob ntawm qhov sib piv stoichiometric (14.7 qhov cua rau 1 feem roj), pa sensor ua 0.45 volts.

Kuj Paub, cov pa oxygen twg tseem ceeb dua? pem hauv ntej pa sensor nyob rau hauv lub tso zis manifold yog " tseem ceeb tshaj plaws "vim nws tau siv rau kev tswj roj pa sensor tsuas yog siv los saib xyuas kev ua haujlwm ntawm lub catalytic converter.

Kuj nug, ua li cas thaum lub ntsuas pa oxygen mus tsis zoo?

Thaum koj muaj ib tug tsis zoo oxygen sensor , koj lub tsheb yuav ua haujlwm tau zoo dua qub, qee zaum nws tuaj yeem ua haujlwm tsis zoo, tsis ua haujlwm tsis zoo ntawm lub qhov rooj khov kho, pib teeb meem nyuaj, ua rau lub cav tshawb xyuas lub teeb tuaj, thiab yuav ua rau muaj roj ntau.

Kuv puas yuav tsum hloov tag nrho o2 sensors ib zaug?

Nws yog qhov zoo tshaj plaws rau hloov koj sensors hauv khub. Piv txwv li, yog koj hloov sab laug sab laug sensor , koj yuav tsum kuj hloov txoj cai downstream. Nws yog qhov tshwm sim tias ntawm cov tsheb feem ntau, cov cai yuav raug teeb tsa hauv 30-60 hnub tom qab thawj zaug hloov sensor.
