RV차량 및 소형승합차량의 휘발성유기화합물 배출특성 연구 = A Study on the VOCs Emission Characteristics of RV and MPV

다국어 초록 (Multilingual Abstract)

Volatile organic compounds (VOCs) are well known as ozone precursors from photochemical reactions and contribute to the formation of photochemical smog which pose health hazards. Also, some of these compounds directly affect the human health due to their toxicity such as benzene. In this study, NMVOCs composition in exhaust gas from recreational vehicle (RV) and (MPV) were characterized using a chassis dynamometer. The results for NMVOCs have reported that alkanes emission was higher than alkenes, aromatics and cycloalkanes due to reactive of diesel oxidation catalysts. The NMVOCs composition according to carbon number was highly distributed between C3 and C6~C8. During the engine cold start condition, NMVOCs emission was higher compared to the engine hot start condition due to the increased catalytic activity. The NMVOCs emission with DPF increased compared to that without DPF. The results of this study will be provide to calculate VOCs emissions from mobile source.
