실도로 주행 PEMS를 이용한 상용차의 가스 상 유해대기오염물질 배출 특성 연구

In this study, A PEMS (Portable Emissions Measurement Systems) was installed in diesel and gasoline commercial vehicles to determine the emission factors of Hazard Air Pollutants (HAPs) in gas-phase according to various driving conditions. The correlation of PEMS was performed before actual road test. As a result of comparing the used PEMS with the CVS of the chassis dynamometer, it can be confirmed that it has very high reliability. As a result of analyzing data using the Moving Average Method (MAW) among the data evaluation methods proposed by the EU using PEMS, both the diesel and gasoline commercial vehicles were found to satisfy both route compliance and path completeness in Urban, Rural and Motorway sections. As a result of evaluation of HAPs according to running roads, the emission factor is higher in urban driving conditions in the order of Urban > Rural > Motorway, though there is a slight difference in the tendency of emission factors for each mode depending on individual components of VOCs. However, this tendency was not observed for carbonyl compounds. HAPs emissions are very low in this test vehicle, and various test environmental factors may act as interferences.
