Abstract

Understanding actual exhaust emissions is important in executing appropriate measures to reduce them. To this end, we 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. We also clarified the current status of exhaust emissions according to the results of measurement.
Additionally, we investigated a number of the operation modes in commercial trains, and proposed the test cycle concept which was applied to evaluation of measurements based on the analysis results.
