Kaya ndi zonyamula anthu mtunda wautali kapena zonyamula katundu, magalimoto olemera a dizilo amagwira ntchito yofunika kwambiri pamoyo watsiku ndi tsiku wa anthu. Komabe, chifukwa cha mawonekedwe a dizilo, mpweya wamchira wotuluka m'magalimoto a dizilo olemera kwambiri uli ndi ma nitrogen oxides ndi zinthu zina zovulaza zomwe zimawononga kwambiri mpweya. Akuti pali magalimoto a dizilo okwana 21 miliyoni ku China, omwe ndi 4.4% yokha ya magalimoto onse ku China, koma ma nitrogen oxides ndi zinthu zina zomwe zimatulutsidwa ndi 85% ndi 65% ya magalimoto. okwana utsi galimoto motero. Choncho, pofuna kupititsa patsogolo mpweya wabwino komanso kuchepetsa kuipitsidwa, boma la China likutchula miyezo yotulutsa mpweya wakunja ndipo linanena kuti miyezo isanu ndi umodzi ya dziko lonse ya galimoto zolemera za dizilo idzakhazikitsidwa m'dziko lonselo kuyambira pa July 1, 2021. Pofuna kuyankha ndondomeko za dziko ndi kuteteza chilengedwe, masensa awiri a nayitrogeni ndi okosijeni ayenera kuikidwa pagalimoto iliyonse yamtundu wa diesel isanu ndi umodzi yolemera. Kodi nitrogen ndi oxygen sensor ndi chiyani? Kodi kachipangizo ka nayitrogeni ndi mpweya kamakhala ndi gawo lotani powongolera kutulutsa kwa utsi?
Sensa ya nayitrogeni ndi okosijeni ndi sensa yomwe imagwiritsidwa ntchito kuzindikira nayitrogeni ndi mpweya wamafuta mu injini ya dizilo. Sensa ya NOx idzakweza zomwe zapezeka pa NOx pakompyuta (ie ECU), ndipo ECU idzawongolera kuchuluka kwa jakisoni wa urea wa SCR dongosolo malinga ndi deta, kuti muchepetse kutulutsa kwa NOx ndikuzindikira kuwunika kwa OBD kwa SCR. zigawo. M'mawu ena, ngati palibe nayitrogeni ndi mpweya sensa, ECU sangathe molondola kuweruza ndende ya asafe ndi mpweya mankhwala mu mpweya mchira, ndiyeno sangathe molondola kulamulira urea jekeseni kuchuluka kwa SCR. The nayitrogeni ndi mpweya pawiri mu mpweya mchira wa magalimoto dizilo sangathe bwino kuyeretsedwa, ndipo ndende yawo adzakhala kuposa dziko umuna muyezo.
Sensa ya nayitrogeni ndi mpweya ndi chowonjezera chofunikira pamagalimoto adizilo olemetsa ndipo ayenera kusinthidwa pafupipafupi. M'mikhalidwe yabwinobwino, moyo wautumiki wa nayitrogeni ndi sensa ya okosijeni ndi maola 6000.
Akuti kuchuluka kwa magalimoto a dizilo ku China kudzafika 2100 isanafike 2025, ndipo kufunikira kwa msika wotsatsa pambuyo pa masensa a nayitrogeni ndi okosijeni kupitilira 32 miliyoni. Komabe, poyang'anizana ndi kufunikira kwakukulu kotereku, mbali zamagalimoto anthu amati ndizovuta kupeza njira yodalirika yogulira ma sensa a nayitrogeni ndi okosijeni, chifukwa palibe opanga ambiri omwe amatha kupanga masensa apamwamba kwambiri a nayitrogeni ndi okosijeni ndikupereka. mu nthawi ku China.
Yunyi electric (stock code 300304), yomwe idakhazikitsidwa mu Julayi 2001, ili ndi zaka 22 za R&D komanso luso lopanga zida zamagalimoto. Monga chokhacho chopangira nayitrogeni ndi mpweya wokhala ndi OEM yopanga ku China, Yunyi Electric ali ndi unyolo wophatikizika kwambiri wamakampani komanso mphamvu zopanga zolimba, zomwe zimatha kupatsa makasitomala ma sensor apamwamba a nayitrogeni ndi okosijeni munthawi yochepa.
M'malingaliro a anthu a Yunyi, kupanga phindu kwa makasitomala ndiye chifukwa chokhacho chamakampani. Poyang'anizana ndi msika waukulu wa nayitrogeni ndi masensa okosijeni, magetsi a Yunyi nthawi zonse amalimbikira kuganiza momwe makasitomala amawonera, ndipo amapereka makasitomala apamwamba kwambiri kudzera mu R & D wamphamvu ndi mphamvu yopanga, kuti apange phindu kwa makasitomala ndikuthandizira makasitomala. kupeza bwino bizinesi. Mukufuna kudziwa zambiri za masensa a nayitrogeni ndi okosijeni? Chonde dinani ulalo:https://www.yunyi-china.net/denoxtronic-scr-systems/
