Vehicle emission test modes for certification have limitation to reflect various real driving conditions. To raise the effectiveness of vehicle emission regulation, it is required to estimate vehicle emission based on real road driving. In this study, real driving emission measurements have been conducted for 3 Korean light-duty vehicles with PEMS. The driving routes consisted of urban, rural and motorway in Seoul and Incheon. For averaged emission in routes, a gasoline and a LPG vehicles showed the lower THC, CO and NOx emission than those of CVS-75 used for emission certification. But real driving NOx of a light duty diesel vehicle is quite higher than limit value of NEDC. The results of analysis with moving averaging window have shown also that real driving NOx of a light duty diesel vehicle is quite different from that of NEDC driving.

Pollutant emissions from heavy-duty vehicles have been controlled with the engine emission test in certification phase. Recently, real driving emission measurement with PEMS has been introduced to in-use compliance test for pollutant emissions of heavy-duty vehicles. Korea has followed European regulation for reducing air pollutants from heavy duty vehicles. In this study, real driving emission measurements have been conducted for 2 Korean heavy-duty trucks of EURO-5. The measured data were analyzed with the work-based moving averaging window method in the provision of in-service conformity test for EURO-6. The real driving NOx emission are quite higher than the limit value of ETC. The value of 90 percentile for NOx conformity factor was about 2.0. It is higher than the requirement of EURO 6.

For emission regulation of Korean light-duty vehicles, CARB provisions have been introduced to gasoline and LPG vehicles and European provisions to diesel vehicles. In UN ECE WP29, world-harmonized light-duty test procedure (WLTP) has been being developed with participation of EU, Japan, US EPA, Korea and so on. In the future, WLTP is expected to be introduced to pollutant and CO2 emission test in Korea. A draft harmonized test cycle, WLTC, was released and validation test is ongoing which will be done by 2012. In this study, we compare driving parameters of WLTC with those of conventional Korean emission certification test modes and analyze the characteristics to reflect Korean real driving patterns with chi square test method. 3 Korean vehicles were tested with draft WLTC and the results were compared with those of conventional test cycles.
