Nitrogen oxide sensor yog ib qho tseem ceeb tshaj plaws hauv kev ua haujlwm.Thaum lub sijhawm ua haujlwm ntawm lub cav, nws niaj hnub kuaj pom cov nitrogen oxide sensor concentration ntawm cov yeeb nkab ntawm lub cav, txhawm rau xyuas seb puas muaj nitrogen oxide sensor emission raws li txoj cai.Hnub no nqe lus no feem ntau yuav qhia txog nitrogen oxide sensor.
Dab tsi yog Nitrogen Oxide Sensor
Nitrogen oxide sensors sawv cev rau kev tsim kho tshiab uas tuaj yeem muab tso rau hauv cov roj av ntshiv lub tshuab ua ib feem ntawm kev tswj hwm lub cav ntau dua lossis kev kuaj mob siv los ua pov thawj cov txheej txheem tsim nyog ntawm nitrogen oxide (NOx) kev tswj cov pa tawm.
Cov sensors tuaj yeem suav nrog kev ywj pheej ntawm NOx tso tawm kev tswj hwm thev naus laus zis siv rau ntawm lub tsheb thiab lawv qhov tshwj xeeb yog feem ntau los xyuas NOx kev hloov pauv kev ua haujlwm ntawm lub zog.Lub sensor tuaj yeem ua haujlwm raws li ib feem ntawm cov lus voj voog rau kev tswj hwm ntawm qhov kev tso tawm kom ua tiav lub sijhawm hloov kho thiab ua kom NOx hloov siab los ntseeg.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ib hom NOx sensor yog raws li kev sim thiab kuaj cov khoom siv hluav taws xob electrolyte tsim rau oxygen sensors.Lub dual chamber zirconia tuaj tos nam thiab tseem electro-chemical twj ua hauj lwm ua ke nrog precious hlau tsav electrodes tswj cov pa concentration nyob rau hauv lub sensor thiab hloov lub NOx rau nitrogen.
Cov nyhuv ntawm Nitrogen Oxide Sensor
Raws li lub cav emission txoj cai dhau los ua nruj dua li yav dhau los, lub luag haujlwm ntawm nitrogen oxide sensor lub luag haujlwm yog tshuaj xyuas cov khoom tawm thiab tsim kom muaj cov nitrogen oxide ntau tso rau hauv ib puag ncig.
Lub nitrogen oxide sensor ua haujlwm los ntawm kev txheeb xyuas cov nitrogen oxides los ntawm kev siv lub tshuab electro-catalytic, nrog rau cov khoom uas teb nrog nitrogen oxide.
Ib qho hluav taws xob dhau los ntawm electrolyte tuaj yeem txheeb xyuas tias muaj pes tsawg nitrogen oxide tam sim no, nrog rau qhov hluav taws xob tseem ceeb tshaj plaws uas sawv cev rau qib nitrogen oxide ntau dua.
Npaj cov nitrogen oxide sensor me ntsis uas muaj cov nyiaj nitrogen oxide tsim tawm heev.Vim tias rooj plaub, nws yeej yuav xa cov ntaub ntawv mus rau SCR system, uas yuav hloov qhov tshwm sim los ua kom lub tsheb thauj khoom kom txaus siab cov lus qhia tawm.
Yog li ntawd, nitrogen oxide sensor yog ib qho tseem ceeb rau SCR system nyob rau hauv diesel-powered autos kom ntseeg tau tias lub tsheb tseem ua raws li cov qauv emissions xav tau.
Qee Cov Lus Qhia rau Kho Nitrogen Oxide Sensor
Nitrogen Oxide Sensors muaj cov cuab yeej siv niaj hnub nyuaj.Hauv qab no yog qee cov tswv yim ua haujlwm kho kom nco qab:
- Lub kaw lus tsis txaus ntseeg yuav teeb tsa nitrogen oxide DTCs.
- Nco ntsoov ntsuas lub doser valve ua ntej hloov nitrogen Oxide sensors.
- Tom qab hloov lub ntsuas nitrogen oxide, nco ntsoov xyuas cov ntaub ntawv daws teeb meem rau txhua yam txheej txheem rov pib dua.
- Nitrogen oxide sensor tsis tuaj yeem cais tawm ntawm nitrogen oxide thiab ammonia
Ua ib qho DPF regen yuav tso tawm ammonia los ntawm SCR stimulant.
Raws li cov kev cai emissions ntawm diesel roj tsheb tau dhau los ua nruj dua, lub luag haujlwm ntawm nitrogen oxide sensors tau dhau los ua qhov tseem ceeb.Peb yog VW nitrogen oxide sensor Hoobkas.Muaj kev txaus siab, txais tos hu rau peb.
