I-nitrogen oxides (NOx) iyiqembu lamagesi asebenza kakhulu akhiwa lapho uphethiloli ushiswa emazingeni aphezulu okushisa.Lokhu kuhlanganisa izinqubo zokusha ezimotweni, izikhungo zikagesi nezinqubo zezimboni.Ukukhishwa kwe-nitrogen oxide kuye kwaqashelwa njengengxenye ebalulekile yokungcoliswa komoya futhi kuye kwaxhunyaniswa nohlu lwezinkinga zempilo, kuhlanganise nezinkinga zokuphefumula nesifo senhliziyo.

Ukuze kubhekwane nokukhishwa kwe-nitrogen oxide, imboni yezimoto ibisebenza ngokuzikhandla ukuthuthukisa izimoto ezihlanzekile, ezisebenza kahle kakhulu.Izinzwa ze-nitrogen oxide zingobunye bobuchwepheshe obuthuthukisiwe ukusiza ukunciphisa ukukhishwa kwe-nitrogen oxide.

Izinzwa ze-nitrogen oxide ziyingxenye ebalulekile yezinhlelo zesimanje zokulawula ukukhishwa kwezimoto.Igada amazinga egesi ye-nitrogen oxide kusistimu yokukhipha umoya futhi inikeza impendulo kuyunithi yokulawula injini, ukuyivumela ukuthi ilungise ingxube yomoya kaphethiloli ukuze kuncishiswe ukungcola.Lokhu kubalulekile ekuqinisekiseni ukuthi izimoto zithobela imithetho eqinile yokukhipha umoya obekwe ohulumeni emhlabeni jikelele.

Kunezinhlobo ezimbili eziyinhloko zezinzwa ze-NOx ezisetshenziswa ezimotweni: izinzwa zezintambo ezishisayo nezinzwa ze-ceramic.Izinzwa zezintambo ezishisayo zisebenza ngokulinganisa ukuqhutshwa kukagesi kwesici senzwa, esishintshayo ngokushintsha kokugxiliswa kwe-nitrogen oxide.Izinzwa ze-Ceramic, ngakolunye uhlangothi, zikala ukugcwala komoyampilo ku-exhaust futhi ziyisebenzisela ukubala amazinga e-nitrogen oxide.Zombili izinzwa ziklanyelwe ukumelana nezimo ezinzima ezitholakala kumasistimu kagesi, okuhlanganisa izinga lokushisa eliphezulu namagesi abolayo.

Izinzwa ze-nitrogen oxide zidlala indima ebalulekile ekuqinisekiseni ukuthi izimoto zihlangabezana nezindinganiso zokukhipha umoya futhi zisebenza kahle.Ihlinzeka ngempendulo yesikhathi sangempela kuyunithi yokulawula injini, ukuyivumela ukuthi ithuthukise ngokuqhubekayo ingxube ye-fuel-air ukuze isebenze kahle kakhulu.Lokhu akusizi kuphela ukunciphisa ukukhishwa okuyingozi kodwa futhi kuthuthukisa ukusebenza kahle kukaphethiloli kanye nokusebenza kwemoto iyonke.

Ngokungeziwe endimeni yazo yokulawula ukungcola, izinzwa ze-NOx zingakwazi ukuxilonga izinkinga ezingaba khona ngesistimu yokukhipha umoya wemoto.Uma inzwa ithola amazinga e-nitrogen oxide aphezulu ngokungavamile, ingaqalisa ukukhanya “kwenjini yokuhlola”, ixwayise umshayeli ngezinkinga ezingaba khona ezidinga ukuxazululwa.Lokhu kusiza ukuvimbela izinkinga ezingathi sína nezimba eqolo, okwenza izinzwa ze-NOx zibe ithuluzi elibalulekile ekunakekeleni imoto nokuphila isikhathi eside.

Njengoba umhlaba uqhubeka nokugxila ekunciphiseni ukungcoliswa komoya kanye nokulwa nokushintsha kwesimo sezulu, ukuthuthukiswa nokwamukelwa kabanzi kobuchwepheshe obufana nezinzwa ze-NOx kuzoba okubalulekile.Ngokuqapha nokulawula ngempumelelo ukukhishwa kwe-nitrogen oxide ezimotweni nezinqubo zezimboni, singasebenza ukuze sakhe indawo ehlanzekile, enempilo yezizukulwane ezizayo.

Ngamafuphi, izinzwa ze-nitrogen oxide NOx ziyingxenye ebalulekile yezinhlelo zesimanje zokulawula ukungcola.Idlala indima ebalulekile ekwehliseni ukukhishwa kwe-nitrogen oxide eyingozi ezimotweni nezinqubo zezimboni, okusiza ukuthuthukisa izinga lomoya kanye nempilo yomphakathi.Njengoba siqhubeka sisebenzela ikusasa elisimeme, izinzwa ze-NOx zizoba ithuluzi elibalulekile ekufinyeleleni izinjongo zethu zemvelo.
