Measurement and Evaluation of Exhaust Emissions from Diesel Railcars

Understanding actual exhaust emissions is important in executing appropriate measures to reduce them. To this end, the authors developed an exhaust emission measurement technique that can be executed relatively easily using engine bench test boards at JR rolling stock maintenance depots and in diesel railcars under running conditions. The current status of exhaust emissions is also clarified according to the results of measurement. Additionally, a number of the operation modes in commercial trains are investigated, and a test cycle concept is proposed which was applied to evaluation of measurements based on the analysis results.
