In a four stroke internal combustion engine significant values of torque are present in several orders of the speed of the engine causing torsional vibrations of the crankshaft. The shaft is designed to have its fundamental torsional mode frequency to be very much higher than the speed of the engine. When a component of insignificant moment of inertia is attached to the crankshaft, it is normally considered that its influence on the dynamics is negligible. It is shown in this work that even with a small variation in the moment of inertia or the speed of the engine can cause significant torsional vibrations under certain conditions.
