Inzwa ye-nitrogen oxide ingenye yezingxenye ezibaluleke kakhulu ohlelweni lokucubungula.Ngesikhathi sokusebenza kwenjini, ihlale ibona ukugxilwa kwenzwa ye-nitrogen oxide yepayipi lokukhipha umoya lenjini, ukuze ibone ukuthi ukukhishwa kwenzwa ye-nitrogen oxide kuyahlangabezana yini nezimfuneko ezingokomthetho.Namuhla le ndima izokwethula ikakhulukazi inzwa ye-nitrogen oxide.
Iyini inzwa ye-Nitrogen oxide
Izinzwa ze-nitrogen oxide zimelela indlela emisha engafakwa ezinjinini zikaphethiloli ezingenawo amandla njengengxenye yokulawula injini ebanzi noma uhlelo lokuxilonga olusetshenziswa ukuze kuqinisekiswe inqubo efanele yesistimu yokulawula ukuphuma kwe-nitrogen oxide(NOx).
Lezi zinzwa zingafakwa ngokuzimele kubuchwepheshe bokulawula ukukhishwa kwe-NOx obusetshenziswa emotweni futhi isici sazo ngokuyinhloko ukuhlola ukusebenza kahle kokuguqulwa kwe-NOx kwesikhuthazi.Inzwa ingasebenza njengengxenye yeluphu yamazwana ohlelweni lokulawula kusistimu yokukhipha ukuze yenze ukuguqulwa kwesikhathi kanye nokwandisa ukuguqulwa kwe-NOx.
Umgomo wokusebenza kohlobo olulodwa lwenzwa ye-NOx usekelwe phezu kobuchwepheshe obuqinile be-electrolyte obuvivinyiwe obusungulwe izinzwa ze-oxygen.Isici sokuthatha i-zirconia yamagumbi amabili kanye namaphampu e-electro-chemical asebenza ngokuhambisana nama-electrode omshayeli wensimbi eyigugu ukuze alawule ukugcwala komoyampilo ngaphakathi kwenzwa kanye nokuguqula i-NOx ibe i-nitrogen.
Umthelela Wenzwa Ye-Nitrogen Oxide
Njengoba izinqubomgomo zokukhishwa kwenjini ziba namandla kakhulu kunangaphambili, umsebenzi wenzwa ye-nitrogen oxide ukuhlola okuphumayo nokuthola amanani e-nitrogen oxide akhishelwa endaweni ezungezile.
Inzwa ye-nitrogen oxide isebenza ngokuhlonza ama-nitrogen oxide kusetshenziswa idivayisi ye-electro-catalytic, enomkhiqizo ophendula nge-nitrogen oxide.
I-voltage edlula ku-electrolyte ingahlaziya ukuthi ingakanani i-nitrogen oxide ekhona, namandla kagesi abaluleke kakhulu amelela izinga le-nitrogen oxide elikhudlwana.
Hlela izindawo zenzwa ye-nitrogen oxide ukuthi kunamanani adlulele e-nitrogen oxide akhiqizwayo.Ngoba uma kunjalo, izothumela imininingwane ohlelweni lwe-SCR, oluzoshintsha umphumela ukuze iloli likwazi ukwanelisa imihlahlandlela yokukhishwa.
Ngakho-ke, inzwa ye-nitrogen oxide ibalulekile ohlelweni lwe-SCR ezimotweni ezisebenza ngodizili ukuze kuqinisekiswe ukuthi imoto ihlala ihambisana nezindinganiso ezidingekayo zokukhipha umoya.
Amanye Amathiphu Okulungisa Inzwa Ye-Nitrogen Oxide
Izinzwa ze-Nitrogen Oxide zifaka ubuchwepheshe besimanje obuyinkimbinkimbi.Ngezansi eminye imibono yomsebenzi wokulungisa okufanele uyikhumbule:
- Ukuvalwa kwethamo elibi kungase kusethe i-nitrogen oxide DTCs.
- Qiniseka ukuthi uhlola i-valve yethamo ngaphambi kokushintsha izinzwa ze-nitrogen Oxide.
- Ngemva kokushintsha inzwa ye-nitrogen oxide, qiniseka ukuthi uhlola ulwazi lwesixazululo nganoma yiluphi uhlobo lwezinqubo zokusetha kabusha.
- Inzwa ye-nitrogen oxide ayikwazi ukubandlulula phakathi kwe-nitrogen oxide kanye ne-ammonia
Ukwenza i-regen ye-DPF ngokuqinisekile kuzokwethula i-ammonia kusuka kusivuseleli se-SCR.
Njengoba imithetho yokukhipha izimoto zikadizili iya ngokuya iqina, indima yezinzwa ze-nitrogen oxide iya iba semqoka kakhulu.Siyimboni yezinzwa ze-VW nitrogen oxide.Noma yiziphi izintshisekelo, wamukelekile ukuthintana nathi.
