Nokuba kukuthwala abakhweli kumgama omde okanye kuthutho lwempahla, iimoto zedizili ezinzima zidlala indima ebaluleke kakhulu kubomi bemihla ngemihla babantu. Nangona kunjalo, ngenxa yeempawu zedizili, igesi yomsila ekhutshwa zizithuthi zedizili ezinobunzima ziqukethe i-nitrogen oxides kunye nezinye izinto eziyingozi ezibangela ukungcoliseka komoya okukhulu. Kuqikelelwa ukuba kukho malunga nezigidi ezingama-21 zeemoto zedizili eTshayina, ezibalelwa kwi-4.4% kuphela yenani leemoto eTshayina, kodwa initrogen oxides kunye nomcimbi okhutshwa ngabo zenza i-85% kunye ne-65% yezithuthi. ukukhutshwa kwezithuthi zizonke ngokulandelelanayo. Ngoko ke, ukuze kuphuculwe umgangatho womoya kunye nokunciphisa ungcoliseko, urhulumente waseTshayina ubhekisela kwimigangatho yokukhutshwa kwamanye amazwe kwaye uchaza ukuba imigangatho yesizwe emithandathu yokukhutshwa kweenqwelo zedizili ezinzima ziya kuphunyezwa kwilizwe lonke ukususela ngoJulayi 1, 2021. Ukuze uphendule kwimigaqo-nkqubo kazwelonke kunye ukukhusela okusingqongileyo, izinzwa ezimbini zenitrogen kunye neoksijini kufuneka zifakwe kwisithuthi ngasinye sedizili ezintandathu zesizwe esinzima. Yintoni inzwa yenitrogen kunye neoksijini? Yiyiphi indima edlalwa yi-nitrogen kunye ne-oxygen sensor kwinkqubo yokulawula ukukhutshwa kombhobho?
I-nitrogen kunye ne-oxygen sensor yinzwa esetyenziselwa ukufumanisa i-nitrogen kunye ne-oxygen compounds kwi-injini ye-diesel exhaust. I-sensor ye-NOx iya kulayisha idatha ye-concentration ye-NOx efunyenweyo kwikhompyutheni yebhodi (oko kukuthi i-ECU), kwaye i-ECU iya kulawula inani le-urea injection ye-SCR inkqubo ngokwedatha, ukwenzela ukunciphisa ukukhutshwa kwe-NOx kunye nokuqaphela ukubeka iliso kwe-OBD ye-SCR. amacandelo. Ngamanye amazwi, ukuba akukho nitrogen kunye neoksijini isivamvo, ECU akakwazi ukugweba ngokuchanekileyo yoxinaniso nitrogen kunye neoksijini iikhompawundi kwirhasi yomsila, kwaye ke ayikwazi ukulawula ngokuchanekileyo isixa naliti urea SCR. I-nitrogen kunye ne-oxygen compounds kwi-gas yomsila wezithuthi ze-diesel ayikwazi ukuhlanjululwa ngokufanelekileyo, kwaye ukugxininiswa kwabo kuya kudlula umgangatho wokukhutshwa kwelizwe.
I-nitrogen kunye ne-oxygen sensor yi-accessory efunekayo kwizithuthi ze-diesel ezinzima kwaye kufuneka zitshintshwe rhoqo. Ngaphantsi kweemeko eziqhelekileyo, ubomi benkonzo ye-nitrogen kunye ne-oxygen sensor yi-6000 iiyure.
Kuqikelelwa ukuba inani leemoto ze-diesel e-China ziya kufikelela kwi-2100 ngaphambi kwe-2025, kwaye imfuno epheleleyo yeemarike emva kokuthengisa i-nitrogen kunye ne-oxygen sensors iya kudlula i-32 yezigidi. Nangona kunjalo, phambi kwemfuno enkulu kangaka, iindawo zemoto abantu bathi kunzima ukufumana umjelo othembekileyo wokuthenga i-nitrogen kunye ne-oxygen sensors, kuba baninzi abavelisi abakwazi ukuvelisa i-nitrogen ephezulu kunye ne-oxygen sensors kunye nokuhambisa. ngexesha labo eTshayina.
IYunyi yombane (ikhowudi yesitokhwe 300304), eyasekwa ngoJulayi 2001, ineminyaka engama-22 ye-R & D kunye namava emveliso kushishino lwamalungu emoto. Njengokuphela komvelisi wesivamvo se-nitrogen kunye ne-oksijini enamava emveliso ye-OEM e-China, i-Yunyi Electric inomxokelelwane wezoshishino ohlangeneyo kakhulu kunye nomthamo oqinileyo wemveliso, onokubonelela abathengi nge-nitrogen ephezulu kunye ne-oksijini zoluvo ngexesha elifutshane.
Kwimbono yabantu baseYunyi, ukudala ixabiso kubathengi kuphela kwesizathu sobukho bamashishini. Ukujongana nemarike enkulu enokubakho ye-nitrogen kunye ne-oxygen sensors, iYunyi yombane ihlala igxininisa ekucingeni ngokwembono yabathengi, kwaye ibonelela abathengi ngobonelelo olukumgangatho ophezulu nge-R & D eyomeleleyo kunye nomthamo wemveliso, ukuze wenze ixabiso kubathengi kwaye uncede abathengi. ukufikelela kwimpumelelo yoshishino.
