Qhov sib txawv ntau dua, qhov siab dua qhov hluav taws xob nyeem ntawv . Ib oxygen sensor yuav feem ntau tsim kom txog li 0.9 volts thaum cov roj sib tov yog nplua nuj thiab muaj me ntsis unburned oxygen hauv tso . Thaum lub sib tov yog lean, lub cov sensor tso zis hluav taws xob yuav poob mus txog 0.1 volts.

Tsuas yog li ntawd, kuv yuav ua li cas paub yog tias kuv lambda sensor tsis zoo?

Cov tsos mob ntawm faulty lambda sensor

  1. Lub cav ceeb toom teeb yuav qhia rau ntawm lub dashboard.
  2. Lub tsheb jerks thaum pib.
  3. Kev siv roj ntau heev.
  4. Tsawg zog cav thaum ua kom nrawm.
  5. Kev nce hauv kev tso tawm cov pa roj lom.

Ib qho ntxiv, dab tsi tuaj yeem ua rau nyeem ntawv Lambda siab? Yog qhov txhaum yog a siab lambda nyeem ntawv , nrog a siab O2 nyeem ntawv tab sis nrog CO thiab HC ib txwm muaj nyeem ntawv , feem ntau ua rau yog tom qab cov pa ya tawm. Ib tug me me tso pa system pa tawm yuav xau huab cua mus rau hauv lub tso pa ua ntej txhua yam tshuab tau raug kuaj pom.

Qhov thib ob, tus ntsuas lambda ntsuas dab tsi?

Cov pa sensor (los yog lambda sensor , qhov twg lambda hais txog huab cua-roj sib npaug sib npaug, feem ntau txhais los ntawm λ) yog ib qho khoom siv hluav taws xob uas ntsuas qhov feem ntawm cov pa (O2) hauv cov pa lossis kua raug tshuaj xyuas. Nws tau tsim los ntawm Robert Bosch GmbH thaum xyoo 1960s nyob rau hauv kev saib xyuas ntawm Dr. Günter Bauman.

Koj puas tuaj yeem tsav nrog lub teeb meem lambda sensor?

O2 sensor tsis muaj dab tsi ua nrog roj. Koj tuaj yeem tsav tsheb nws tsuas zoo nrog lub tawg sensor ; nws tsuas yog txhais lub tsheb tau tsis saib xyuas kom raug thiab kho cov roj/cua sib xyaw kom raug. Nws yuav yuav tsum tau kho ua ntej koj ua tau tau txais daim ntawv tso pa huv huv, tab sis koj ua tau tseem tsav nws nyob rau lub sijhawm no.
