Kwicandelo leloli elinzima, kukho amacandelo amaninzi adlala indima ebalulekileyo ekuqinisekiseni ukuba isithuthi sisebenza ngokufanelekileyo kwaye sidibana nemimiselo yokusingqongileyo.Elinye icandelo elinjalo yi-nitrogen oxide sensor, ebeka iliso kwaye ilawule amanqanaba e-nitrogen oxide (NOx) akhutshwa yi-injini yelori.Kule bhlog, siza kujonga ngakumbi ukubaluleka kweenzwa zelori ze-NOx kunye nefuthe labo ekusebenzeni kwesithuthi kunye nokusingqongileyo.
Izivamvo ze-nitrogen oxide ziyinxalenye ebalulekileyo yenkqubo yokulawula ukukhutshwa kwelori.Basebenza ngokulinganisa ingxinano yegesi yenitrogen oxide kumjelo wokukhupha nokuthumela loo datha kwiyunithi yokulawula injini yelori (ECU).I-ECU ke isebenzisa olu lwazi ukulungelelanisa umxube we-fuel-air kunye nokwandisa inkqubo yokutshisa, ekugqibeleni ukunciphisa ukukhutshwa kwe-nitrogen oxide ekhutshwe emoyeni.
Enye yeenzuzo eziphambili ze-NOx sensors kukuba zinceda iilori ukuba zithobele imigangatho engqongqo yokukhutshwa.Njengoko imimiselo yokusingqongileyo iya isiba ngqongqo ngakumbi, abavelisi beelori baphantsi koxinzelelo lokunciphisa ungcoliseko oluyingozi olukhutshwa zizithuthi zabo.I-NOx sensors yenza iilori ukuba zihlangabezane nale migangatho ngokuqhubekayo ukubeka iliso kunye nokulawula amanqanaba e-NOx, ngokunciphisa impembelelo yokusingqongileyo kwimisebenzi yabo.
Ukongeza kwiinzuzo zokusingqongileyo, i-NOx sensors inceda ukuphucula ukusebenza kunye nokusebenza kakuhle kwelori yakho.Ngokubonelela ngedatha yexesha langempela kumanqanaba e-nitrogen oxide, ezi zinzwa zenza ukuba i-ECU yenze uhlengahlengiso oluchanekileyo ekusebenzeni kweenjini, ngaloo ndlela iphucula uqoqosho lwamafutha kunye nokunciphisa ukunxiba kweenjini.Oku akulunganga kuphela kokusingqongileyo, kodwa kwakhona konga imali yabaqhubi beelori ngendlela yokunciphisa ukusetyenziswa kwamafutha kunye neendleko zokuyigcina.
Ukongezelela, i-NOx sensors idlala indima ebalulekileyo ekuqinisekiseni ukuba iilori zixhotyiswe nge-Selective Catalytic Reduction (SCR) esebenzayo inkqubo.Iinkqubo ze-SCR zisebenzisa ii-catalysts ukuguqula igesi yenitrogen oxide ibe yinitrogen engenabungozi kunye nomphunga wamanzi.Nangona kunjalo, ukuze inkqubo ye-SCR isebenze ngokufanelekileyo, ixhomekeke ekufundweni kwe-NOx echanekileyo yokulinganisa i-dosage ye-diesel exhaust fluid (DEF) efakwe kwi-exhaust stream.Ngaphandle kwenzwa ye-NOx ethembekileyo, ukuphumelela kwenkqubo ye-SCR kuya kuphazamiseka, okubangele ukwanda kwe-NOx emissions kunye nokungahambelani nokungathotyelwa kwemimiselo yokukhutshwa.
Kubalulekile kubaqhubi beloli kunye nabaphathi beenqwelo-moya ukuba baqaphele ukubaluleka kweenzwa ze-NOx kwaye babeke phambili ukugcinwa kwazo kunye nokutshintshwa xa kuyimfuneko.Ngokuhamba kwexesha, i-NOx sensors inokungcola okanye ingaphumeleli ngenxa yokuvezwa kwamaqondo aphezulu kunye neemeko zokusebenza ezinzima.Ukuhlolwa rhoqo kunye nokutshintshwa kwezi zinzwa kubalulekile ekuqinisekiseni ukuba ilori yakho iyaqhubeka nokusebenza ngokufanelekileyo kwaye ihlangabezana nemigangatho yokukhutshwa.
Isishwankathelo, ii-sensors zeloli ze-NOx ziyinxalenye ebalulekileyo ekunciphiseni ukukhutshwa okuyingozi kwizithuthi ezinzima.Ngokubeka iliso ngokuqhubekayo kunye nokulawula amanqanaba e-nitrogen oxide, ezi zivamvo azincedi kuphela iilori ukuba zihambelane nemimiselo yokusingqongileyo kodwa zinceda ukuphucula ukusebenza kunye nokusebenza kakuhle.Njengoko imboni yezothutho iqhubeka nokubeka phambili ukuzinza, indima ye-NOx sensors ekunciphiseni impembelelo yokusingqongileyo yeelori ayikwazi ukujongelwa phantsi.Abaqhubi beelori kufuneka baqonde ukubaluleka kwezi zivamvo kwaye batyale imali kugcino olululo nololongo ukuze kuxhamle imisebenzi yabo kunye nokusingqongileyo.
