I-Nitrogen oxides (NOx) liqela leegesi ezisebenza kakhulu ezenziwa xa isibaso sitshiswa kumaqondo obushushu aphezulu.Oku kubandakanya iinkqubo zokutsha kwizithuthi, amaziko ombane kunye neenkqubo zoshishino.Ukukhutshwa kwe-nitrogen oxide kuye kwaqatshelwa njengegalelo elibalulekileyo lokungcoliswa komoya kwaye liye ladibaniswa noluhlu lweengxaki zempilo, kubandakanywa iingxaki zokuphefumula kunye nesifo senhliziyo.
Ukujongana nokukhutshwa kwenitrogen oxide, ishishini leemoto liye lasebenza ngokungakhathali ukuphuhlisa izithuthi ezicocekileyo nezisebenzayo.Izinzwa ze-nitrogen oxide zezinye zeetekhnoloji eziphuhlisiwe ukunceda ukunciphisa ukukhutshwa kwe-nitrogen oxide.
Izinzwa ze-nitrogen oxide ziyinxalenye ebalulekileyo yeenkqubo zokulawula ukukhutshwa kwezithuthi zanamhlanje.Ibeka esweni amanqanaba egesi ye-nitrogen oxide kwinkqubo yokukhupha kwaye inika ingxelo kwiyunithi yokulawula injini, ivumela ukuba ilungelelanise umxube we-fuel-air ukunciphisa ukukhutshwa.Oku kubalulekile ekuqinisekiseni ukuba izithuthi ziyayithobela imithetho engqongqo yokukhupha izinto ezikhutshwayo esekwe ngoorhulumente kwihlabathi liphela.
Kukho iintlobo ezimbini eziphambili ze-NOx ezisetyenziselwa izithuthi: i-sensors zocingo ezishushu kunye ne-ceramic sensors.Izinzwa zocingo ezifudumalayo zisebenza ngokulinganisa ukuhanjiswa kombane kwento yokuva, etshintsha ngotshintsho kwi-nitrogen oxide concentration.Izinzwa zeCeramic, kwelinye icala, zilinganisa i-oxygen concentration kwi-exhaust kwaye ziyisebenzise ukubala amanqanaba e-nitrogen oxide.Zombini izinzwa zenzelwe ukumelana neemeko ezinzima ezifumaneka kwiinkqubo zokukhupha, kubandakanywa ubushushu obuphezulu kunye neegesi ezidliwayo.
Izinzwa ze-nitrogen oxide zidlala indima ebalulekileyo ekuqinisekiseni ukuba izithuthi ziyahlangabezana nemigangatho yokukhutshwa kunye nokusebenza ngokufanelekileyo.Ibonelela ngengxelo yexesha lokwenyani kwiyunithi yolawulo lwe-injini, eyivumela ukuba iqhubeke nokwandisa umxube we-fuel-air ukuze isebenze ngokufanelekileyo.Oku akuncedi kuphela ukunciphisa ukukhutshwa okuyingozi kodwa kuphucula ukusebenza kakuhle kwamafutha kunye nokusebenza kwesithuthi siphela.
Ukongeza kwindima yabo ekulawuleni ukukhutshwa, i-NOx sensors ingakwazi ukuxilonga iingxaki ezinokubakho ngenkqubo yokukhupha isithuthi.Ukuba i-sensor ibona amanqanaba aphezulu e-nitrogen oxide ngokungaqhelekanga, inokubangela "i-injini yokukhangela" ukukhanya, ilumkisa umqhubi kwiingxaki ezinokuthi ziqwalaselwe.Oku kunceda ukukhusela iingxaki ezinzulu kunye neendleko, ukwenza i-NOx sensors isixhobo esibalulekileyo ekugcinweni kwesithuthi kunye nokuphila ixesha elide.
Njengoko ihlabathi liqhubeka ligxininisa ekunciphiseni ukungcoliseka komoya kunye nokulwa nokutshintsha kwemozulu, ukuphuhliswa kunye nokwamkelwa ngokubanzi kweetheknoloji ezifana ne-NOx sensors kuya kubaluleka.Ngokujonga ngokufanelekileyo kunye nokulawula ukukhutshwa kwe-nitrogen oxide kwizithuthi kunye neenkqubo zoshishino, sinokusebenza ukudala indawo ecocekileyo, enempilo kwizizukulwana ezizayo.
Ngamafutshane, izinzwa ze-nitrogen oxide NOx ziyinxalenye ebalulekileyo yeenkqubo zokulawula ukukhutshwa kwanamhlanje.Idlala indima ephambili ekunciphiseni ukukhutshwa kwe-nitrogen oxide eyingozi kwizithuthi kunye neenkqubo zoshishino, inceda ekuphuculeni umgangatho womoya kunye nempilo yoluntu.Njengoko siqhubeka sisebenzela kwixesha elizayo elizinzileyo, i-NOx sensors iya kuba sisixhobo esibalulekileyo ekufezekiseni iinjongo zethu zokusingqongileyo.
