<p>Output (torque) characteristics of each cylinder are estimated by a simple structure. A device for measuring torque of an engine is provided with a torque detecting section (4) for detecting, as a signal, output torque of the engine having cylinders, a rotation detecting section (3) for detecting the rotational angle of a rotating section to which a piston of each cylinder is connected in the engine, a top mark detecting section (2) for detecting the rotational angle of the piston of each cylinder, and a torque calculating section (10) for estimating torque characteristics of each cylinder on the basis of the following: the signal of the output torque detected by the torque detecting section (4), the rotational angle of the rotating section detected by the rotation detecting section (3), the rotational angle of the piston of each cylinder detected by the top mark detecting section (2), the number of the cylinders of the engine, and the number of cycles of the engine. The torque calculation section (10) estimates, as torque characteristics of each cylinder, either peak torque of each cylinder or the combustion angle at which the peak torque is obtained.</p> |
