Khoom taw qhia
Cov pa oxygen sensor pub rov qab cov ntaub ntawv qhia txog cov roj sib xyaw rau ECU los ntawm kev kuaj xyuas cov pa oxygen hauv lub cav tso pa, thiab nws tau nruab rau ntawm cov yeeb nkab ua ntej peb-txoj kev catalyst.
Lub ntsiab lus tseem ceeb ntawm oxygen sensor siv los tsim cov teeb liab hluav taws xob yog zirconium dioxide (ZrO2), uas muaj txheej platinum ntawm nws sab nrauv, thiab txheej txheej ceramics nyob rau sab nraud ntawm platinum los tiv thaiv platinum electrode. Sab sab hauv ntawm lub ntsiab lus ntawm cov pa oxygen sensor raug rau cov huab cua, thiab sab nraud dhau los ntawm cov pa tso tawm los ntawm lub cav. Thaum qhov ntsuas kub ntawm qhov ntsuas kub siab tshaj 300 ℃, yog tias cov pa oxygen ntawm ob sab sib txawv heev, lub zog hluav taws xob yuav raug tsim tawm ntawm ob sab. Cov ntsiab lus oxygen nyob rau hauv lub sensor yog siab vim nws yog ventilated rau cov huab cua. Thaum sib tov yog nyias, cov ntsiab lus ntawm cov pa oxygen nyob rau hauv cov pa tso pa yog siab. Qhov sib txawv ntawm cov ntsiab lus oxygen ntawm ob sab ntawm lub sensor yog me me, yog li lub zog hluav taws xob tsim los ntawm nws kuj tseem me me (txog 0.1V). Txawm li cas los xij, thaum sib tov ntau dhau lawm, cov ntsiab lus ntawm cov pa oxygen hauv cov pa tawm tsawg heev, qhov sib txawv ntawm cov pa oxygen ntawm ob sab ntawm cov khoom rhiab heev, thiab cov hluav taws xob tsim hluav taws xob kuj loj (txog 0.8V). Lub tshuab cua sov hauv cov pa oxygen sensor yog siv los ua kom sov lub ntsiab lus rhiab kom nws tuaj yeem ua haujlwm li qub.
Yog tias cov pa oxygen sensor tsis muaj cov teeb liab tso tawm lossis cov teeb liab tso tawm yog qhov txawv txav, nws yuav ua rau kom cov roj noj thiab cov pa paug ntawm lub cav, ua rau tsis ruaj tsis khov ceev, misfire thiab chattering. Feem ntau ua txhaum ntawm oxygen sensor yog:
1) Manganese lom. Txawm hais tias cov roj av leaded tsis siv lawm, tus neeg sawv cev antiknock hauv cov roj av muaj cov manganese, thiab manganese ions lossis manganate ions tom qab combustion yuav ua rau saum npoo ntawm cov pa oxygen sensor, yog li nws tsis tuaj yeem tsim cov cim ib txwm muaj.
2) Cov pa roj carbon deposition. Tom qab qhov saum npoo ntawm daim ntawv platinum ntawm cov pa oxygen sensor yog carbon-deposited, cov teeb liab voltage tsis tuaj yeem tsim tawm.
3) Tsis muaj cov teeb liab tawm hluav taws xob vim kev sib cuag tsis zoo lossis qhib Circuit Court nyob rau hauv Circuit Court sab hauv ntawm cov pa sensor.
4) Cov khoom siv ceramic ntawm cov pa oxygen sensor puas lawm thiab tsis tuaj yeem tsim cov teeb liab voltage.
5) Cov hlau tsis muaj zog ntawm lub tshuab hluav taws xob oxygen tau kub hnyiab los yog nws cov hluav taws xob tawg, uas ua rau cov pa oxygen tsis tuaj yeem ncav cuag qhov kub ua haujlwm sai.
