Hais txog nws pib oxygen sensor

Kev lag luam pib tam sim no yog ib lub lag luam loj tshaj plaws rau kev siv cov sensors hauv ntiaj teb. Cov pa oxygen sensor tau nruab rau hauv cov yeeb nkab ntawm lub tsheb thiab siv los xyuas cov pa oxygen hauv cov pa tawm. Yog li ntawd, raws li cov teeb liab tau txais los ntawm cov pa oxygen sensor, nws tuaj yeem rov qab mus rau qhov kev tswj hwm kom zoo-kho cov roj txhaj tshuaj, uas txo cov pa phem thiab txuag lub zog.
Thaum lub ntsuas pa tsis ua haujlwm, lub khoos phis tawj ntawm lub tshuab hluav taws xob hauv hluav taws xob yuav tsis tuaj yeem tau txais cov ntaub ntawv ntawm cov pa oxygen concentration hauv cov pa tso pa, yog li nws yuav tsis tuaj yeem ua cov lus tawm tswv yim ntawm cov pa roj sib piv, nce roj noj thiab tso pa paug ntawm lub cav. Surge thiab lwm yam txhaum phenomena. Yog li ntawd, qhov txhaum yuav tsum raug tshem tawm lossis hloov lub sijhawm. Cov laj thawj tseem ceeb rau qhov tsis ua haujlwm ntawm oxygen sensor yog:
Lub davhlau ya nyob twg txuas yog xoob, corroded, lub davhlau ya nyob twg tsis tiaj tus, lossis cov hlua txuas txuas tsis raug, kev sib txuas virtual, thiab lwm yam.
Cov dej noo, condensation, los yog cov kab mob uas nkag mus rau hauv lub sensor tuaj yeem ua rau lub sensor tsis ua haujlwm lossis teeb liab tsis zoo.
Mechanical shocks xws li cov pob zeb ya tuaj yeem ua rau lub sensor puas.
Oxygen sensor "poisoning" (piv txwv li Pb, S, Br, Si, Mh, thiab lwm yam):
Oxygen sensor aging.
Oxygen sensor nto thaj chaw carbon.
Cov cua kub tsis kam hlau yog tshuab.
Yuav ua li cas xyuas nws pib oxygen sensor
Kev tshuaj xyuas cov cua sov resistors
Tshem tawm qhov hluav taws kub ntawm lub tsheb, nrhiav cov pa oxygen sensor raws cov yeeb nkab ntawm lub tsheb, thiab tshem tawm cov hlua khi ntawm cov pa oxygen sensor. Siv multimeter los ntsuas qhov kev tiv thaiv ntawm lub tshav kub lub davhlau ya nyob twg thiab hauv av davhlau ya nyob twg hauv cov pa oxygen sensor davhlau ya nyob twg, thiab sib piv qhov ntsuas qhov tsis kam nrog qhov tshwj xeeb tsis kam ntawm lub tsheb qauv. Yog hais tias nws cov nqi kuj yog infinite, cov hlau sab hauv yog tawg thiab cov pa sensor yuav tsum tau hloov.
Kev ntsuas ntawm Oxygen Sensor Voltage
Txoj Kev 1: Tshem tawm cov kab hluav taws xob sib txuas ntawm cov pa oxygen sensor, txuas ib lub xaim los ntawm cov lus tawm tswv yim ntawm cov pa oxygen sensor los ntawm kev xa mus rau daim duab hluav taws xob ntawm lub tsheb qauv, ntxig cov hlua hluav taws xob sib txuas, cia lub cav khiav, thiab ntsuas cov lus tawm tswv yim. voltage ntawm lub tsheb los ntawm cov hlau. Thaum nws pib oxygen sensor yog qhov qub, nws cov lus tawm tswv yim voltage yuav ua kom qhov kev hloov pauv ntawm 0.45v vim yog kev tswj xyuas cov lus teb. Nyob rau hauv txoj kev thib ob, tus tswv lub tsheb hloov qhov concentration ntawm qhov sib tov los ntawm "kev ntxhov siab ceev ceev ntawm lub pedal thiab tso nws tam sim ntawd". Nrog rau kev nyuaj siab ntawm lub accelerator pedal, cov roj txhaj tshuaj los ntawm cov roj txhaj qhov chaw nres nkoj ntawm lub cav nce, qhov sib tov concentration nce, thiab cov lus tawm tswv yim voltage nce. Nrog rau cov txheej txheem ntawm kev tso cov accelerator pedal, cov roj txhaj tshuaj txo qis, qhov sib xyaw concentration ua thinner, thiab tawm tswv yim voltage txo. Thaum lub sij hawm tus txheej txheem no, tus nqi ntawm cov lus tawm tswv yim voltage ntsuas los ntawm lub voltmeter yuav tsum thaws rov qab mus rau hauv ib tug voltage range. Yog hais tias tus pointer ntawm lub voltmeter tsis thaws, nws txhais tau hais tias cov pa sensor tau puas lawm.
Txheeb xyuas qhov pom ntawm cov pa oxygen sensor rau kev hloov xim
Koj tuaj yeem tshawb xyuas seb puas muaj qhov ua txhaum los ntawm kev saib xyuas cov xim hloov ntawm sab saum toj ntawm cov pa oxygen sensor. Lub teeb grey sab saum toj yog xim ib txwm; sab saum toj dawb qhia tias cov pa sensor tau kis nrog silicon; cov xim av sab saum toj qhia tau hais tias cov pa oxygen sensor tau kis nrog txhuas; dub saum yog tshwm sim los ntawm carbon deposition.
Auto manufacturing siv ntau lub sensors, thiab cov pa oxygen sensor yog ib qho ntawm ntau lub sensors. Lub hav zoov ntawm oxygen sensor yog tsim nyog rau kev txuag hluav taws xob lossis kev tiv thaiv ib puag ncig los siv cov tswv yim txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Yog li ntawd, rau kev tshuaj xyuas ntawm cov pa oxygen sensor nyob rau hauv lub tsheb, nws yog ib qho tsim nyog los tswj qhov zoo.
