초록

자동차에서 배출되는 배기가스가 대도시의 대기 오염원 중 큰 비중을 차지하고 있다. 특히 디젤이나 CNG버스 등 대중교통의 내연기관 차량은 매일 총 주행거리와 운행시간이 길고 차량 수량이 많기 때문에 배출가스 저감 대책이 시급하다. 본 논문에서는 실제로 전기버스의 도로 주행시험을 통한 연료소모율(km/kWh)을 측정하였다. 측정값을 근거로 버스 한 대당 내연기관과 전기버스에서 발생되는 CO2배출량을 계산하였다. 전기버스를 시내버스로 대체할 경우 CNG버스 대비 예상되는 이산화탄소 저감 등 환경개선 효과와 더불어 전기버스로 대체가 확대될 경우 부가적인 효과를 분석하였다.

In particular, vehicles with internal combustion engines of public transportation such as diesel and CNG buses are in urgent need of measures to reduce emissions as they have a long daily total mileage, long driving hours and a large number of vehicles. In this paper, the fuel consumption rate (km/kWh) was actually measured through road test of electric buses. Based on the measured values, CO2 emissions from internal combustion engines and electric buses were calculated per bus. In addition to environmental improvement effects such as the expected reduction of carbon dioxide compared to CNG buses when replacing city buses with electric buses, additional effects were analyzed when the replacement of CNG buses is expanded to electric buses.
