Nitrogen oxides (NOx) yog ib pawg ntawm cov roj reactive heev uas tau tsim thaum roj hlawv ntawm qhov kub thiab txias.Qhov no suav nrog cov txheej txheem combustion hauv tsheb, fais fab nroj tsuag thiab cov txheej txheem kev lag luam.Nitrogen oxide emissions tau raug lees paub tias yog ib qho tseem ceeb rau kev ua pa phem thiab tau txuas nrog ntau yam teeb meem kev noj qab haus huv, suav nrog teeb meem ua pa thiab kab mob plawv.
Txhawm rau hais txog nitrogen oxide emissions, kev lag luam automotive tau ua haujlwm tsis tu ncua los txhim kho cov tsheb huv, ua haujlwm zoo dua.Nitrogen oxide sensors yog ib qho ntawm cov thev naus laus zis tsim los pab txo qis nitrogen oxide emissions.
Nitrogen oxide sensors yog ib feem tseem ceeb ntawm cov tsheb niaj hnub emission tswj systems.Nws saib xyuas cov roj nitrogen oxide qib hauv cov pa tawm thiab muab cov lus tawm tswv yim rau lub cav tswj lub cav, tso cai rau nws los kho cov roj-cua sib tov kom txo qis emissions.Qhov no yog qhov tseem ceeb rau kev ua kom cov tsheb ua raws li cov kev cai emissions nruj zuj zus los ntawm tsoomfwv thoob ntiaj teb.
Muaj ob lub ntsiab ntawm NOx sensors siv nyob rau hauv tsheb: kub hlau sensors thiab ceramic sensors.Rhaub hlau sensors ua hauj lwm los ntawm kev ntsuas cov hluav taws xob conductivity ntawm lub sensing caij, uas hloov nrog kev hloov nyob rau hauv nitrogen oxide concentration.Ceramic sensors, ntawm qhov tod tes, ntsuas cov pa oxygen hauv cov pa thiab siv nws los xam cov qib nitrogen oxide.Ob lub sensors yog tsim los tiv thaiv cov xwm txheej hnyav uas pom nyob rau hauv cov pa tawm, nrog rau qhov kub thiab txias thiab corrosive gases.
Nitrogen oxide sensors ua lub luag haujlwm tseem ceeb hauv kev ua kom lub tsheb ua tau raws li cov qauv emissions thiab ua haujlwm zoo.Nws muab cov lus tawm tswv yim ntawm lub sijhawm tiag tiag rau chav tswj lub cav, tso cai rau nws ua kom zoo dua cov roj-cua sib tov rau kev pom kev ua haujlwm emissions.Qhov no tsis tsuas yog pab txo cov pa phem, tab sis kuj txhim kho roj efficiency thiab tag nrho lub tsheb ua haujlwm.
Ntxiv nrog rau lawv lub luag haujlwm hauv kev tswj cov emissions, NOx sensors tuaj yeem kuaj xyuas cov teeb meem uas muaj peev xwm nrog lub tsheb lub tso pa tawm.Yog hais tias lub sensor pom qhov txawv txav siab nitrogen oxide, nws tuaj yeem ua rau lub teeb "check engine", ceeb toom tus neeg tsav tsheb rau cov teeb meem uas yuav tsum tau daws.Qhov no pab tiv thaiv cov teeb meem loj thiab raug nqi ntau dua, ua rau NOx sensors yog cov cuab yeej tseem ceeb hauv kev saib xyuas tsheb thiab kev ua haujlwm ntev.
Raws li lub ntiaj teb tseem tab tom tsom rau kev txo cov pa phem thiab tiv thaiv kev hloov pauv huab cua, kev txhim kho thiab kev siv thev naus laus zis xws li NOx sensors yuav yog qhov tseem ceeb.Los ntawm kev saib xyuas thiab tswj cov pa nitrogen oxide tawm ntawm lub tsheb thiab cov txheej txheem kev lag luam, peb tuaj yeem ua haujlwm los tsim kom muaj ib puag ncig zoo dua qub rau yav tom ntej.
Nyob rau hauv luv luv, nitrogen oxide NOx sensors yog ib feem tseem ceeb ntawm niaj hnub emission tswj systems.Nws ua lub luag haujlwm tseem ceeb hauv kev txo qis nitrogen oxide emissions los ntawm cov tsheb thiab cov txheej txheem kev lag luam, pab txhim kho huab cua zoo thiab kev noj qab haus huv rau pej xeem.Raws li peb txuas ntxiv ua haujlwm mus rau lub neej yav tom ntej, NOx sensors yuav yog lub cuab yeej tseem ceeb hauv kev ua tiav peb cov hom phiaj ib puag ncig.
