Isivamvo senitrogen oxide yenye yezona zinto zibaluleke kakhulu kwinkqubo yokucubungula.Ngethuba lokusebenza kwe-injini, ihlala ibona i-nitrogen oxide sensor concentration ye-exhaust pipe ye-injini, ukuze ibone ukuba i-nitrogen oxide emission emission ihlangabezana neemfuno zomthetho.Namhlanje esi sicatshulwa siza kwazisa ikakhulu i-nitrogen oxide sensor.
Yintoni iNitrogen oxide Sensor
Abenzi boluvo be-nitrogen oxide bamele ukuvela kwezinto ezintsha ezinokufakwa kwiinjini ze-petroli ezinqamlekileyo njengenxalenye yolawulo olubanzi lwe-injini okanye inkqubo yokuxilonga esetyenziselwa ukuqinisekisa inkqubo efanelekileyo ye-nitrogen oxide (NOx) inkqubo yokulawula ukukhupha.
Ezi zinzwa zingabandakanywa ngokuzimeleyo kwi-teknoloji yokulawula ukukhutshwa kwe-NOx esetyenziswe kwi-automobile kunye nesici sabo ngokuyinhloko ukujonga ukuguqulwa kokuguqulwa kwe-NOx kwe-stimulant.I-sensor inokusebenza njengenxalenye ye-loop yamazwana kwisistim solawulo kwinkqubo yokukhutshwa kwempahla yokwenza ukuguqulwa kwexesha kunye nokwandisa ukuguqulwa kwe-NOx.
Umgaqo wokusebenza kolunye uhlobo lwenzwa ye-NOx isekelwe phezu kovavanyo oluqinileyo lwetekhnoloji ye-electrolyte esekwe kwi-oxygen sensors.Igumbi elimbini i-zirconia yokuchola inkalo kunye neepompo ze-electro-chemical zisebenza ngokudityaniswa ne-electrode yomqhubi wentsimbi exabisekileyo ukulawula uxinzelelo lwe-oksijini ngaphakathi kwenzwa kunye nokuguqula i-NOx kwi-nitrogen.
Isiphumo seNgqungquthela yeNitrogen oxide
Njengoko imigaqo-nkqubo yokukhutshwa kwe-injini iba ngqongqo ngakumbi kunangaphambili, umsebenzi wesivamvo senitrogen oxide kukuhlola ukukhutshwa nokuseka imiyinge yenitrogen oxide ekhutshelwe kanye kokusingqongileyo.
I-nitrogen oxide sensor isebenza ngokuchonga i-nitrogen oxides ngesixhobo se-electro-catalytic, kunye nemveliso ephendula nge-nitrogen oxide.
Umbane ogqithise kwi-electrolyte unokuhlalutya ukuba yinitrogen oxide engakanani ekhoyo, kunye namandla ombane abaluleke ngakumbi amele inqanaba lenitrogen oxide.
Ngenisa amabala ezivamvo zenitrogen oxide ukuba kukho izixa ezigqithisileyo zenitrogen oxide eyenziweyo.Kuba imeko, ngokuqinisekileyo iya kuthumela ulwazi kwinkqubo ye-SCR, eya kuthi emva koko itshintshe isiphumo ukuze ilori ikwazi ukwanelisa izikhokelo zokukhutshwa.
Ngenxa yoko, i-nitrogen oxide sensor ibalulekile kwinkqubo ye-SCR kwiimoto ze-diesel-powered autos ukuqinisekisa ukuba isithuthi sihlala sihambelana nemigangatho yokukhutshwa efunekayo.
Ezinye iiNgcebiso zokuLungisa i-Nitrogen Oxide Sensor
IiSensors zeNitrogen oxide zibonisa itekhnoloji entsonkothileyo yale mihla.Ngezantsi kukho iimbono zomsebenzi wokulungisa ekufuneka uzikhumbule:
- Ukuvalwa kwedosi eyingozi kunokuseta initrogen oxide DTCs.
- Qinisekisa ukuvavanya ivalve yedosi phambi kokutshintsha izinzwa zenitrogen Oxide.
- Emva kokutshintsha inzwa ye-nitrogen oxide, qiniseka ukuba uhlola ulwazi lwesisombululo kulo naluphi na uhlobo lweenkqubo zokuseta kwakhona.
- Inzwa ye-nitrogen oxide ayinakucalula phakathi kwenitrogen oxide kunye ne-ammonia
Ukwenza i-regen ye-DPF ngokuqinisekileyo kuya kuphehlelela i-ammonia kwi-SCR stimulant.
Njengoko imimiselo yokukhutshwa kwezithuthi zedizili iya isiba ngqongqo ngakumbi, indima ye-nitrogen oxide sensors iya ibaluleka ngakumbi.Siyi-VW nitrogen oxide sensor factory.Nawuphi na umdla, wamkelekile ukuba uqhagamshelane nathi.
