    Abstract: A counterweight arrangement for an internal combustion engine with three cylinders. The internal combustion engine having a crankshaft rotating about an axis of rotation, with three cranks which succeed one another in the axial direction with respect to the axis of rotation and are distributed at angular intervals of 120° and each crank corresponding to a respective cylinder, the counterweight arrangement including at least two counterweights for at least partial compensation of inertia forces caused by rotating masses on the crankshaft, wherein exactly two counterweights are provided for the two outer cranks, at least one of the two counterweights being arranged in a position which is rotated about the crankshaft axis with respect to an assigned crank through angle (αcounter), the amount of which differs from 30°+N*180°, N being equal to a natural number or equal to zero.
