초록

Despite of recently strengthened vehicle emission regulations, NOx emissions are not decreased in urbanareas because of discrepancies between certification emission test modes and real driving conditions. Thus, researcheson RDE-LDV (Real-driving Emission-Light-duty Vehicle) have been conducted actively using PEMS (PortableEmissions Measurement Systems). In the present study, NOx emissions were measured for 5 Korean light duty vehiclesfor real driving conditions including city, combined, highway, and up-downhill test route. Emission characteristics wereanalyzed for averaged NOx emissions per unit driving distance of each driving test routes. Furthermore, MAW(Moving Average Window) method based on CO2 emissions from WLTC, which will be supported for EU regulations,was utilized. It was revealed that DRs (deviation ratios) for diesel vehicles (i.e., 5.1 ~ 8.4) were greater than gasolinevehicles (less than 0.15). Especially DR of diesel vehicle for up-downhill test route was 8.4, which indicates severeNOx emissions.
