NOx Sensor - Nitrogen Oxide Sensor e ana i ka NOx i luna a me lalo o ka SCR catalyst e hoʻomalu i ka dosing Urea a me ka hōʻoia i ka hana o ka pūnaewele SCR.
ʻO ka laulā huahana a Weili no NOx Sensor:
Ma mua o 100 mau mea
Nā hiʻohiʻona:
Me ka 3 Cavity Design hou loa.
ʻO ka mea sensing he chip ceramic i loaʻa i kahi kaapuni hoʻomehana, kahi ala liʻiliʻi e alakaʻi ana i loko o 3 cavities, oxygen pumping circuit a me NOx decomposition circuit.
1St ʻO ka lua: E hoʻopau i ke kinoea ma lalo o ka lua mua ma o ka pā ākea
2nd Cavity: NO2 i loaʻa i ke kinoea hoʻopau i hoʻololi ʻia me NO
3rd Cavity: NO komo i ke kolu o ka lua a me 2NO→N2 + O2 ma M2 electrode
