Abstract

Recently, an emission test procedure using a portable emissions measurement system(PEMS) has received much attention as an effective means of controlling real driving emissions from light-duty diesel vehicles. The PEMS-based test procedure will be implemented from 2017 in Europe and Korea as a complementary test procedure for certification and regulation. In the present study, on-road NOx emissions were measured for four kinds of Euro 5 Korean light-duty diesel vehicles under real driving conditions, including urban, rural, and motorway test routes. The real driving emission characteristics were evaluated using both a moving averaging window(MAW) and the weighted emission method(WEM). The evaluated NOx emission results (under real driving conditions) from the MAW and WEM showed similar tendencies for the test vehicles and routes, while exceeding the certification emission limit by 1.8~8.5 and 2.0~10.6 times, respectively.

PEMS(Portable Emissions Measurement System)를 이용한 배기가스 시험절차는 소형 디젤자동차의 실제도로 배출가스를 효과적으로 제어하기 위한 수단으로 최근에 많은 주목을 받고 있으며, 현재의 배기가스 인증규제 시험절차의 제도적 보완장치로 2017년에 한국과 유럽에서 시행될 예정이다. 본 연구에서는 국내에 운행 중인 유로 5 소형 디젤자동차 4대에 대한 실제도로 NOx 배출량을 도심, 교외 및 자동차 전용도로에서 측정하였으며, 측정 결과를 이동평균구간 및 가중평균 배출량 방법으로 분석하였다. 시험 차량 및 주행경로에 대한 두 방법의 실제도로 NOx 배출량 분석결과는 유사한 경향을 갖는 것으로 나타났으며, 이동평균구간 분석방법의 경우 배출 허용기준을 1.8 ~ 8.5배, 가중평균 배출량은 허용기준을 2.0 ~ 10.6배 초과하는 것으로 분석되었다. 본 결과를 바탕으로 실도로 주행 조건에서 NOx 배출량 분석에 대한 기술적 토대를 확보하였고, 향후 배출가스 관리를 위한 정책적 기반 데이터로 활용가능하다.
