철도 디젤차량에서 배출되는 가스상 오염물질의 배출량 추정

Estimation of Gases Air Pollutants Emission Rates Exhausted from Railroad Diesel Rolling Stocks

Of those off-road diesel engines, the railroad diesel rolling stocks (RDRS) for passenger and freight transportation become a growing issue since they are emitting enormous amounts of various air pollutants. Furthermore, up to the present time, emissions from these sources are not well controlled. One of main purposes in this study is to develop emission factors for the RDRS and to estimate a total amount of major air pollutants from the RDRS in Korea. Prior to develop a Korean mode emission factor, the emission factor from the USEPA was simply applied for comparative studies. As a conclusion, based on the emissions calculated from both the USEPA mode and the KoRail mode, the RDRS is considered as one of significant mobile sources of major air pollutants including NOx and CO, and thus management plans and control strategies for the RDRS must be established to improve air quality near. future in Korea.
