Abstract
For largely automatic determination of the moment of inertia of, in particular, an internal combustion engine on a testing stand, speed n and indicated torque M.sub.M are measured under controlled operating conditions in both a run-up phase as well as in a coasting phase. In order to eliminate the loss moment in the determination of the moment of inertia, the measuring points of the respectively same speed from the run-up phase and the coasting phase are interpreted in combination, this enabling an exact determination of the moment of inertia in a very simple way with the devices that are usually already present at a testing stand.
