摘要

The estimated exhaust emissions from railway vehicles in Turkey were presented. The emissions of nitrogen oxides (NO_X), hydrocarbon compounds (HC), carbon monoxide (CO), particulate matter (PM), sulfur dioxide (SO_2) and carbon dioxide (CO_2) from the diesel locomotives and railcars were calculated using the railway traffic data recorded by Turkish State Railways (TSR) for the period of 2000-2005. EPA emission factors were used for different vehicle types and operation modes such as shunting and line-hauling. Total emissions from railway vehicles in Turkey were estimated as 384 t y~(-1) for HC, 1016 t y~(-1) for CO, 6799 t y~(-1) for NO_X, 256 t y~(-1) for PM, 357 t y~(-1) for SO_2 and 383 537 t y~(-1) for CO_2 for the year 2005. The distribution of emissions with respect to type of railway vehicles shows that the mainline locomotives contribute ～91% to the total emissions. The increases of 22%, 39% and 49% in the current numbers of mainline locomotives, shunting locomotives and diesel railcars, respectively corresponding to the full capacity of railway network in Turkey will increase the annual emissions to 431 ty~(-1) for HC, 1121 ty~(-1) for CO, 7399 t y~(-1) for NO_X, 342 t y~(-1) for PM, 552 t y~(-1) for SO_2 and 420 256 t y~(-1) for CO_2. Total railway emissions constitute 0.15%, 0.08% and 4.21% of total Turkish traffic emissions for HC, CO and NO_X, respectively.
