High NOx cov pa tawm tau tshwm sim thaum lub cav cov pa-roj sib tov sib xyaw heev. Qhov no yuav ua ua los ntawm ib qho teeb meem nrog lub tsheb lub pa oxygen sensor, malfunctioning air flow and coolant sensors or a leak in the fuel system.
Hauv qhov no, kuv yuav txo kuv qib NOx li cas?
Cov Tswv Yim Txo Cov Txiaj Ntsig NOx
- los ntawm Marc Karell thiab Amit Chattopadhyay.
- Roj hloov. Kev hloov roj yog qhov yooj yim tshaj plaws thiab muaj peev xwm ua tau zoo tshaj plaws los txo NOx emissions.
- Flue-gas recirculation (FGR).
- Tsawg NOx burners.
- Derating.
- Kev txhaj tshuaj los yog dej.
- Staged combustion.
- Roj reburning.
Tsis tas li ntawd, NOx ppm txhais li cas? Ntsuas uas ntsuas NOx feem ntau nyeem hauv Tshooj Ib Leeg ( PPM ). Vim tias huab cua ntau dhau nyob rau hauv cov pa roj nkev dilutes NOx feem pua, ntau tus tub ceev xwm hauv cheeb tsam tau xaiv tus qauv siv cov pa roj pa oxygen nyeem rau NOx nyeem tau raug kho.
Zoo sib xws, dab tsi yog NOx ua tsis tiav?
tshuab fail NOx tshwm sim los ntawm kev mob nkeeg. General Motors Multiport Fuel Injection cav muaj peev xwm ua tsis taus kev tso tawm cov qauv ntsuas vim yog ntau dhau Oxides ntawm Nitrogen qib hauv cov pa pa. Nov yog qee cov kauj ruam los txiav txim siab thiab kho qhov ua rau siab NOx tso pa tawm.
NOx emissions txhais li cas?
Nitric oxide (cov NOx ) NOx yog ib qho kev teev npe ntawm cov tshuaj nitrogen TSIS thiab NO2. NOx tso tawm pab txhawb rau cov kua qaub thiab tsim cov av hauv av ozone uas tau puas ecosystems, tsiaj thiab nroj tsuag lub neej. NOx reacts nrog ammonium (NH4 +), dej vapor thiab lwm cov tebchaw thiab cov ntaub ntawv nitric acid (HNO3) thiab cov khoom me me.
