Abstract
Engine measuring equipment for obtaining engine torque regarded as necessary for engine performance assessments for a short time period during a period when engine revolution is under a transient state is disclosed. The engine measuring equipment includes a central control unit for controlling throttle opening degrees due to revolution of the engine and load torque of the dynamometer; a detector connected to an output shaft of the engine, for detecting measurement data including at least revolution and shaft torque of the engine driven by controlling the central control unit; and a signal processing unit for measuring engine torque based on measurement data from the detector. The signal processing unit operates so as to calculate the engine torque based on time series data of the revolution and the shaft torque detected with the detector to measure engine torque from transient state data.
