試験装置。 An engine that is connected to a clutch and a transmission and whose speed is controlled by a control device that has a throttle opening control system in the minor loop of the speed control system, and a dynamo that is connected to the output shaft of the transmission and absorbs power through torque control. an engine testing device comprising: a first calculation means for estimating an output torque response of the engine to a throttle opening command of the throttle opening control system; A second calculating means calculates the engine load torque by multiplying the nominal value, and the throttle opening is adjusted so that the estimated value of the first calculating means and the calculated value of the second calculating means match when the clutch is engaged. An engine testing device characterized by comprising: third calculation means for controlling the increase/decrease of the attitude.
