주행 경로 특성에 따른 실제 도로 주행 환경에서의 Emission Budget 방법론을 활용한 소형 경유자동차 배출가스 특성 분석 = Characteristics of real-driving emissions with LDV by driving route using the emission budget methodology
The draft of Euro-7 included provisions for Emission Budget and Any Trip. The Emission Budget is calculated in mg when the vehicle distance is 10km or less, including the period before the engine stabilizes. When the distance exceeds 10km, it is calculated in g/km. Any Trip involves testing under standardized conditions, rather than evaluating emissions on a fixed, predetermined route. In this study, the Any Trip test, proposed in the Euro-7 draft, was conducted by dividing it into multiple severity levels. Emissions were then analyzed using the Emission Budget method. A PEMS (Portable Emissions Measurement System) was installed in the test vehicle to measure emissions. The measured emissions (mg) were analyzed for each driving data set, considering conditions under 10km.
