An engine data acquisition and processing device is developed for the purpose of labor saving
in diesel railcars maintenance. The feature of the device lies in the torque measurement of a
diesel engine which is mounted on a diesel railcar. The theory of the torque measurement is that
the use of slip speed characteristics of a torque converter on a transmission provide the engine
flywheel torque. The device was tested on a main line of JR after a test at RTRI-JR. The test
result was satisfactory.
