Time-resolved calculation during the cold start period of FCC and BCC has been tried in view of HC emission and energy. Light off time (LOt) calculation of NEDC was implemented for the first time. Category in this first cycle of mode was discerned four kinds of regions: 1) key-on and 11sec idle, 2) short acceleration which BCC`s power is demanded and start of catalyst warm-up,, 3) steady and declined speed which catalyst warmed-up, 4) re-idle which Lot of FCC is reached. Test for temperature measurement was implemented on the different loadings of FCC. Calculation of FCC bed can actually be conducted according to the simplified region area done previous FTP vehicle. Result was shown with good differentiations. AU53 measure, which was firstly applied to the Euro-5 vehicle with low speed, indicated a good correlation with measured data besides FTP driven vehicle with high speed is applied in calculation. Consequently by combined major variables comprising of FCC we could forecast Lot values by modulation of major variables like A/F and RPM of Vehicle, heat capacity of FCC.
