FTIR을 이용한 국내 승용차 Non-CO₂ 온실가스 분석

Chassis dynamometer testing in connection with high-resolution FTIR spectroscopy was used to measure exhaust emissions of nitrous oxide(N₂O) and methane(CH₄) from a representative fleet of several vehicles. Exhaust emissions were collected for three driving cycles: CVS-75, NEDC(ECE+EUDC), KIER city mode. The average N₂O and CH₄ emissions are increased in driving cycle with higher average speed and aggressive driving condition, as expected. The previously reported conversion factors of CH₄/THC and N₂O/NO x could not be supported in LPG-powered and diesel vehicles with DPF.
