Nitrogen oxides (NOx) ke litšila tse kotsi tse hlahisoang ke ho chesoa ha mafura a mafura a likoloi le mekhoa ea indasteri.Lintho tsena tse silafatsang li ka ama bophelo ba batho le tikoloho hampe, tsa baka mathata a ho hema le ho hlahisa mosi.Ho fokotsa tlhahiso ea nitrogen oxide, likoloi tse ngata le lisebelisoa tsa indasteri li na le lisensara tsa nitrogen oxide ho beha leihlo le ho laola litšila tsena tse kotsi.
Li-sensor tsa nitrogen oxide ke karolo ea bohlokoa ea mekhoa ea morao-rao ea ho laola mesi kaha li thusa ho netefatsa hore likoloi le lisebelisoa tsa indasteri li sebetsa ka har'a meeli ea taolo.Li-sensor tsena li sebetsa ka ho lemoha bongata ba li-nitrogen oxides ka har'a mosi le ho fana ka maikutlo ho sistimi ea taolo ea enjene, ho e lumella ho etsa liphetoho ho ntlafatsa ho tuka le ho fokotsa tlhahiso ea nitrogen oxide.
Ho na le mefuta e mengata e fapaneng ea li-sensor tsa NOx, ho kenyelletsa le li-sensor tsa chemiluminescence le li-electrochemical sensors.Li-sensor tsa Chemiluminescence li sebetsa ka ho lekanya leseli le hlahisoang nakong ea karabelo ea lik'hemik'hale lipakeng tsa nitrogen oxides le likhase tse sebetsang, ha li-electrochemical sensors li sebelisa metsoako ea lik'hemik'hale ho hlahisa lets'oao la motlakase le lekanang le mahloriso a nitrogen oxide.
E 'ngoe ea liphephetso tse ka sehloohong tsa ho qapa li-sensors tsa NOx ke ho netefatsa ho nepahala le ho tšepahala ha tsona ho lemoha maemo a tlaase a NOx likhase tse rarahaneng tsa ho qeta.Ho phaella moo, li-sensor li tlameha ho khona ho mamella mocheso o phahameng le maemo a thata a fumanoang tsamaisong ea ho ntša metsi, e leng se etsang hore e be karolo ea bohlokoa ea mekhoa ea ho laola mesi.
Lilemong tsa morao tjena, tsoelo-pele ea theknoloji ea sensor e lebisitse ho nts'etsopele ea li-sensors tse tsoetseng pele le tse bonolo tsa NOx.Mohlala, li-sensor tse ling hona joale li kenyelletsa li-catalysts tse khethang ho fokotsa (SCR), tse ka khethang ho fokotsa nitrogen oxides ho naetrojene le metsi li sebelisa lisebelisoa tse fokotsang joalo ka ammonia.Sena se lumella taolo e nepahetseng haholoanyane ea mesi ea NOx, haholo lienjineng tsa diesel, tse tsejoang ka ho hlahisa maemo a holimo a NOx.
Ho feta moo, ho hlahisoa ha litlhoko tsa tlhahlobo ea likoloi tsa koloi (OBD) ho khothalelitse nts'etsopele ea li-sensor tse tsoetseng pele tsa NOx.Li-sensor tsena li se li khona ho fana ka lintlha tsa nako ea nnete ho sistimi ea koloi ea OBD, e lumellang ho lekola le ho tlaleha ka nepo ho tsoa ha NOx.Sena se thusa ho netefatsa hore koloi e latela maemo a mesi le ho thusa ho tseba mathata afe kapa afe a ka bang teng ka sistimi ea taolo ea mesi.
Ha mebuso lefats'eng ka bophara e ntse e tsoela pele ho tiisa melaoana mabapi le mesi ea NOx, tlhoko ea li-sensor tse tšepahalang le tse nepahetseng tsa NOx e lebelletsoe ho hola.Sena se entse hore ho eketsehe lipatlisiso le nts'etsopele ea theknoloji ea sensor e tsepamisitseng maikutlo ho ntlafatsa ts'ebetso ea sensor, ho tšoarella le ho boloka litšenyehelo.
Qetellong, li-sensor tsa NOx li bapala karolo ea bohlokoa ho fokotsa mesi e kotsi e tsoang ho likoloi le lisebelisoa tsa indasteri.Ha theknoloji ea sensor e ntse e tsoela pele, li-sensor tsena li fetoha tse nepahetseng haholoanyane, tse ka tšeptjoang le tse rarahaneng, tse lumellang hore ho be le taolo e ntlafetseng le ho beha leihlo ho tsoa ha NOx.Ha bohlokoa ba ho fokotsa mocheso oa NOx bo ntse bo eketseha, nts'etsopele ea li-sensor tse tsoetseng pele tsa NOx li tla thusa ho finyella boleng bo hloekileng, bo botle ba moea bakeng sa meloko e tlang.
