Abstract: To provide an engine test apparatus and method, which can easily enhance the test accuracy.The engine test apparatus 10 of the present invention includes: a dynamometer 14, which applies torque to an output shaft of an engine 12 via a shaft member 32; a torque meter 36, which is disposed on the shaft member 32 and measures torque; and a control device 20, which computes a torque command value using a rotational frequency feedback value in order to apply feedback control based on a rotational frequency to the dynamometer 14. The control device 20 subtracts a value measured by the torque meter 14 from the torque command value to find a correction torque command value and controls the dynamometer 14 using the correction torque command value.
