Sensor Yabwino Kwambiri ya Nayitrogeni Oxide

Sensa ya nitrogen oxide ndi imodzi mwazinthu zofunika kwambiri pakupanga makina.Panthawi yogwira ntchito ya injini, nthawi zonse imazindikira kuchuluka kwa nayitrogeni oxide sensor ndende ya chitoliro cha injini, kuti muwone ngati mpweya wa nitrogen oxide sensor umakwaniritsa zofunikira zamalamulo.Masiku ano ndimeyi iwonetsa kwambiri sensa ya nitrogen oxide.

Kodi Nitrogen Oxide Sensor ndi chiyani

Masensa a nayitrojeni okusayidi amayimira luso lamakono lomwe limatha kuyikidwa pa injini zotsamira mafuta ngati gawo la njira yowongolera injini kapena njira yowunikira yomwe imagwiritsidwa ntchito kutsimikizira njira yoyenera ya nitrogen oxide (NOx) yowongolera mpweya.

Masensa awa amatha kuphatikizidwa mosadalira ukadaulo wa NOx discharge control womwe umagwiritsidwa ntchito pagalimoto ndipo mawonekedwe awo ndikuwunika kusinthika kwa NOx kwa cholimbikitsa.Sensa imatha kugwira ntchito ngati gawo la ndemanga kumayendedwe owongolera pamakina otulutsa kuti asinthe kusintha kwa nthawi komanso kukulitsa kutembenuka kwa NOx.

Mfundo yogwiritsira ntchito mtundu umodzi wa sensa ya NOx imachokera pa teknoloji yolimba ya electrolyte yomwe inakhazikitsidwa kuti ikhale ndi mpweya.Zirconia zapawiri zachipinda chonyamula mbali komanso mapampu amagetsi amagetsi amagwira ntchito limodzi ndi maelekitirodi oyendetsa zitsulo zamtengo wapatali kuti aziwongolera kuchuluka kwa okosijeni mkati mwa sensa komanso kusintha NOx kukhala nayitrogeni.

Zotsatira za Nitrogen Oxide Sensor

Pamene ndondomeko zotulutsa injini zikuchulukirachulukira kuposa kale, ntchito ya nitrogen oxide sensor ndikuwunika zomwe zimatuluka ndikukhazikitsa kuchuluka kwa nitrogen oxide komwe kumatulutsidwa m'chilengedwe.

Sensa ya nitrogen oxide imagwira ntchito pozindikira ma nitrogen oxides pogwiritsa ntchito chipangizo cha electro-catalytic, chokhala ndi chinthu chomwe chimayankha ndi nitrogen oxide.

Mpweya wodutsa mu electrolyte ukhoza kusanthula kuchuluka kwa nitrogen oxide yomwe ilipo, ndi mphamvu yowonjezereka yomwe ikuyimira mlingo wochuluka wa nitrogen oxide.

Kufuna nayitrogeni okusayidi sensa mawanga kuti pali kwambiri kuchuluka kwa nitrogen okusayidi kwaiye.Chifukwa chake, itumiza zambiri ku SCR system, yomwe isintha zotsatira zake kuti lorry ikwaniritse malangizo otulutsira.

Chifukwa chake, sensa ya nitrogen oxide ndiyofunikira kuti makina a SCR mu magalimoto oyendetsedwa ndi dizilo awonetsetse kuti galimotoyo imakhalabe yogwirizana ndi zomwe zimafunikira.

Malangizo Ena Okonzekera Sensor ya Nitrogen Oxide

Ma Sensor a Nitrogen Oxide ali ndi ukadaulo wamakono wovuta.M'munsimu muli mfundo zina zofunika kukumbukira pa ntchito yokonza:

• Kutsekeka kwa dozi koopsa kungayambitse ma nitrogen oxide DTCs.

• Onetsetsani kuti mwayesa valavu ya mlingo musanasinthe masensa a nitrogen Oxide.

• Mukasintha sensa ya nayitrogeni oxide, onetsetsani kuti mwayang'ananso chidziwitso chamtundu uliwonse wa njira zokhazikitsiranso.

• Nayitrojeni okusayidi sensa sangathe kusankha pakati nitrogen okusayidi komanso ammonia
  Kuchita DPF regen kudzakhazikitsa ammonia kuchokera ku SCR stimulant.

Pamene malamulo otulutsa mafuta a dizilo akuchulukirachulukira, gawo la nitrogen oxide sensors likukhala lofunikira kwambiri.Ndife fakitale ya VW nitrogen oxide sensor.Zokonda zilizonse, talandiridwa kuti mutilankhule.
