Emkhakheni wobuchwepheshe bezimoto, izinzwa zeGeneral Motors nitrogen oxide (NOx) zidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokunobungani kwezimoto.Inzwa yakhelwe ukuqapha futhi ilawule amazinga e-nitrogen oxide akhishwa isistimu yokukhipha umoya, ngaleyo ndlela isize ukunciphisa ukukhishwa okuyingozi futhi ithuthukise ikhwalithi yomoya iyonke.Kulokhu okuthunyelwe kwebhulogi, sizobhekisisa ukubaluleka kwenzwa ye-NOx ye-GM, ukusebenza kwayo, kanye nomthelela wayo ekusebenzeni kwezimoto nokusimama kwemvelo.
Inzwa ye-GM NOx iyingxenye ebalulekile yesistimu yokulawula ukukhishwa kwemoto.Inesibopho sokuthola ukugcwala kwama-nitrogen oxide kugesi ephumayo futhi idlulisele le datha kuyunithi yokulawula injini (ECU).I-ECU ibe isisebenzisa lolu lwazi ukulungisa ingxube yamafutha omoya futhi yandise inqubo yokuvutha, ekugcineni inciphise ukukhiqizwa kwama-nitrogen oxide.Le nqubo ibalulekile ukuze ihambisane nemithethonqubo eqinile nezindinganiso ezikhishwayo kanye nokunciphisa umthelela wemvelo wezinto ezikhishwa yizimoto.
Enye yezinzuzo eziyinhloko zenzwa ye-GM NOx yikhono layo lokusebenzisa izinhlelo ezikhethiwe zokunciphisa (SCR) ngempumelelo.Amasistimu e-SCR asebenzisa ama-agent anciphisa njenge-urea ukuguqula ama-nitrogen oxide abe yi-nitrogen engenangozi nomhwamuko wamanzi.Isilinganiso senzwa esinembayo samazinga e-nitrogen oxide sinika amandla ukuthasiswa okunembile kwe-reductant, iqinisekisa ukusebenza kahle kwesistimu ye-SCR kanye nokunciphisa ukukhishwa kwekhabhoni.
Ukwengeza, izinzwa ze-GM NOx zidlala indima ebalulekile ekugcineni ukusebenza kahle kanye nokusebenza kwemoto yakho.Ngokuqhubeka nokuqapha nokulawula amazinga e-nitrogen oxide, inzwa isiza ukuvimbela ukusetshenziswa kukaphethiloli ngokweqile, ukucindezeleka kwenjini, kanye nokulimala okungaba khona kusiguquli se-catalytic.Lokhu akugcini nje ngokusiza ukwandisa impilo yezingxenye zokulawula ukukhishwa kwezimoto, futhi kuqinisekisa ukuthi injini isebenza kahle kakhulu, ithuthukisa ukonga kukaphethiloli kanye nokunciphisa izindleko zokunakekela.
Ngaphezu komsebenzi wayo wezobuchwepheshe, inzwa ye-GM NOx nayo inomthelela omkhulu ekusimameni kwemvelo.Ngokulawula ngenkuthalo nokunciphisa ukukhishwa kwe-nitrogen oxide, inzwa isiza ukugcina ikhwalithi yomoya futhi inciphise ukungcola okuyingozi okungathinta kabi impilo yomuntu kanye nemvelo.Njengoba imizamo yomhlaba wonke yokulwa nokushintsha kwesimo sezulu kanye nokungcoliswa komoya iqina, indima yezinzwa ze-GM's NOx ekukhuthazeni ukuthutha okuhlanzekile, okuluhlaza kuya ngokuya kubaluleke kakhulu.
Kubalulekile kubanikazi bezimoto nabachwepheshe bezimoto ukuthi babone ukubaluleka kwenzwa yakho ye-GM NOx futhi babeke phambili ukugcinwa kwayo nokusebenza okufanele.Ukuhlola njalo nokushintshwa kwezinzwa, njengoba kunconywe umenzi, kubalulekile ukuze kuqinisekiswe ukuthi ziyaqhubeka nokusebenza kahle futhi kusize ukunciphisa ukukhishwa kwekhabhoni.Ukwengeza, ukuhlala unolwazi lwakamuva ngenqubekelaphambili yakamuva kubuchwepheshe bezinzwa ze-NOx nokunamathela emikhubeni engcono kakhulu yokulawula ukungcola kungathuthukisa umthelela wemvelo wezimoto ezifakwe le nzwa.
Kafushane, izinzwa ze-GM nitrogen oxide (NOx) ziyingxenye ebalulekile yezinhlelo zesimanje zokulawula ukukhishwa kwezimoto futhi zidlala indima ebalulekile ekwehliseni ukukhishwa okuyingozi, ukuthuthukisa ukusebenza kwenjini kanye nokukhuthaza ukusimama kwemvelo.Ikhono layo lokuqapha ngokunembile futhi lilawule amazinga e-nitrogen oxide libalulekile ekuhambisaneni nemithetho nezindinganiso ezikhishwayo kanye nokunciphisa umthelela wemvelo wokukhishwa kwezimoto.Ngokuqonda nokubona ukubaluleka kwezinzwa ze-NOx ze-GM, singanikela ngokuhlanganyela endaweni ehlanzekile, enempilo yezimoto ezizukulwaneni zamanje nezesikhathi esizayo.
