Abstract
The target substances at Real Driving Emission (RDE) test are mainly CO2 and NOx. In this study, due to its high global warming potential, N2O emission was focused as RDE tests. An on-board FTIR analyzer was installed with a conventional portable emission measurement system (PEMS) to a diesel light duty vehicle. As a result, the CO2 concentrations showed slight differences depending on the measurement principles. It seems that it is caused by Dry/Wet correction. The emission behavior of N2O was compared with CO and NO emission behavior to discuss N2O emission processes.
