Dib-u-soo-noolaynta dhaafka: sideyaasha DPF waxaa lagu dahaadhay lakabka biraha qaaliga ah ee kicinta.Marka la eego xaaladaha heerkulka ku habboon, NO2 ee ay soo saarto unugga DOC waxay si kiimiko ah uga falcelisaa C ee ku jira DPF, isla'egta kiimikaad ee falcelinta waa sida soo socota.
C+2MAYA2=CO2+2MAYA
C+O2=CO2
Isla'egyada ugu muhiimsan ee falcelinta kiimikada ee ka saarista CO iyo HC ee unugga DOC
4HC+5O2=2H2O+4CO
SQF+O2=H2O+CO
2CO+ O2=2CO2
2MAYA+O2=2MAYA2
C+O2=CO2
