Patent ID: 8701616

Claim:
A method for reducing non-uniformities in a rotational speed of a crankshaft of an internal combustion piston engine, wherein a movable compensating mass element is coupled with the crankshaft and is pivotable about an axis that is stationary relative to a engine housing of the internal combustion piston engine, the method comprising: increasing the kinetic energy of the compensating mass element during phases in which the angular speed of the crankshaft would increase if it were not coupled with the compensating mass element, wherein the angular speed of the compensating mass element increases relative to the angular speed of the crankshaft, and decreasing the kinetic energy of the compensating mass element during phases in which the angular speed of the crankshaft would decrease if it were not coupled with the compensating mass element, wherein the angular speed of the compensating mass element decreases relative to the angular speed of the crankshaft.
