Nitrogen oxides (NOx) iboka remagasi anonyanya kuita mhepo anoumbwa kana mafuta apiswa pakupisa kwakanyanya.Izvi zvinosanganisira nzira dzekupisa mumotokari, zvidyarwa zvemagetsi uye maindasitiri maitiro.Nitrogen oxide emissions yave ichizivikanwa sechinhu chakakosha chekusvibiswa kwemhepo uye yakabatanidzwa kune huwandu hwematambudziko ehutano, kusanganisira matambudziko ekufema uye chirwere chemoyo.
Kugadzirisa kuburitswa kwenitrogen oxide, indasitiri yemotokari yanga ichishanda nesimba kugadzira mota dzakachena, dzinoshanda.Nitrogen oxide sensors ndeimwe yetekinoroji yakagadziridzwa kubatsira kuderedza nitrogen oxide emissions.
Nitrogen oxide sensors chikamu chakakosha chemazuva ano emission control system.Iyo inotarisisa nitrogen oxide gasi mazinga mu exhaust system uye inopa mhinduro kune injini yekudzora unit, ichiibvumira kugadzirisa mafuta-mhepo musanganiswa kuderedza kubuda.Izvi zvakakosha pakuona kuti mota dziri kutevedza mitemo inoomesera yekuburitsa hutsi hwakatemerwa nehurumende pasi rese.
Kune maviri makuru marudzi eNOx sensors anoshandiswa mumotokari: inopisa waya sensors uye ceramic sensors.Heated wire sensors inoshanda nekuyera mafambisirwo emagetsi echinhu chekunzwa, chinoshanduka nekuchinja munitrogen oxide concentration.Ceramic sensors, kune rumwe rutivi, inoyera huwandu hweokisijeni mumhepo uye shandisa iyo kuverenga nitrogen oxide mazinga.Masensa ese ari maviri akagadzirwa kuti akwanise kumira nemamiriro ezvinhu akaomarara anowanikwa mumasisitimu emhepo, kusanganisira tembiricha yepamusoro uye gasi rinoparadza.
Nitrogen oxide sensors inoita basa rakakosha mukuona kuti mota dzinosangana nemaitiro ekuburitsa uye kushanda nemazvo.Inopa chaiyo-nguva mhinduro kune injini yekudzora unit, ichiibvumira kuti irambe ichikwidziridza mafuta-mhepo musanganiswa wekuita kwakaringana kuburitsa.Izvi hazvingobatsiri kudzikisira kuburitsa zvinokuvadza chete asi zvakare zvinovandudza kushanda kwemafuta uye kuita kwese kwemotokari.
Pamusoro pebasa ravo mukudzora kuburitsa, NOx sensors inogona kuongorora matambudziko angangove nemotokari yemagetsi.Kana iyo sensor ikaona abnormally yakakwira nitrogen oxide mazinga, inogona kukonzeresa "check injini" mwenje, ichizivisa mutyairi kumatambudziko angangove anofanirwa kugadziriswa.Izvi zvinobatsira kudzivirira matambudziko akakomba uye anodhura, zvichiita kuti NOx sensors ive chishandiso chakakosha mukugadzirisa mota uye hupenyu hurefu.
Sezvo nyika ichiramba ichitarisa kudzikisa kusvibiswa kwemhepo uye kurwisa kushanduka kwemamiriro ekunze, kusimudzira uye kupararira kwekutora matekinoroji akadai seNOx sensors kuchave kwakakosha.Nekunyatso tarisa nekudzora kuburitswa kwenitrogen oxide kubva kumotokari nemaindasitiri maitiro, tinogona kushanda kugadzira nzvimbo yakachena, ine hutano kuzvizvarwa zvinotevera.
Muchidimbu, nitrogen oxide NOx sensors chikamu chakakosha chemazuva ano emission control system.Inobata basa rakakosha mukudzikisa inokuvadza nitrogen oxide kubva kumotokari uye maindasitiri maitiro, zvichibatsira kuvandudza mhando yemhepo uye hutano hweveruzhinji.Sezvo isu tichiramba tichishanda kune ramangwana rakagadzikana, NOx sensors ichava chishandiso chakakosha mukuzadzisa zvinangwa zvedu zvezvakatipoteredza.
