Abstract
Mobile sources are one of the most significant contributors to the inventory of greenhouse gas (GHG). The administration in Korea has set a goal of cutting GHG emissions of vehicles by 34.3% compared to Business As Usual (BAU) by 2020. To achieve this goal, GHG emission standards for vehicles have been applied since 2012, and now light-duty trucks are under consideration to be included to the vehicle types that will be regulated in the new version of GHG emission standards. Therefore, this study focuses on analyzing characteristics of exhaust GHGs (CO2, CH4, and N2O) emissions of diesel light-duty trucks according to their various driving modes. GHGs emissions of diesel light-duty trucks reduced in inverse proportion to the speed of the vehicles. GHGs emissions from the combined mode were 8% and 14% lower than those from the CVS- 75 and NEDC modes, respectively.
자동차 분야는 온실가스 배출량의 상당 부분을 차지하는 주요 배출원으로써, 우리나라는 온실가스 저감을 위하여 2020년까지 교통부문에서는 BAU 대비 34.3%를 감축하는 것을 목표로 하고 있다. 이러한 목표달성을 위하여 2012년부터 자동차 온실가스 배출기준을 적용하고 있으며, 차기 온실가스 배출기준을 마련하는데 있어 소형 화물차량에 대한 대상차종 포함 여부가 검토되고 있다. 이에 본 연구에서는 경유 소형화물 자동차를 대상으로 주행모드에 따른 온실가스 배출특성을 분석하였다. 차속모드인 NIER 모드를 이용하여 분석한 결과, 자동차 온실가스 배출량은 차속이 증가할수록 감소하는 반비례 경향을 나타내었으며,
