Despite of recently strengthened vehicle emission regulations, NOx emissions are not decreased in urban areas because of discrepancies between certification emission test modes and real driving conditions. Thus, researches on RDE-LDV(Real-driving Emission-Light-duty Vehicle) have been conducted actively using PEMS(Portable Emissions Measurement Systems). Emission characteristics were analyzed for averaged NOx emissions per unit driving distance from Driving load. Finally, to utilize the test procedure of RDE-LDV in this study, the representative and repeatability should be considered.
