    摘要： The invention relates to an internal combustion engine comprising a cylinder (12), a piston (18) that is movably located within the cylinder (12), a crankshaft (14) and a connecting rod (22) that connects the piston (18) to a crank pin (30) of the crankshaft (14). Rotatably mounted within the connecting rod top end (26) of the connecting rod (22) is an eccentric sleeve (40), which rotatably holds the crank pin (30) and which can be locked in relation to the connecting rod (22) in at least two rotational orientations by means of a locking device (52). The internal combustion engine is provided with at least one coupling device (100), by means of which the eccentric sleeve (40) can be temporarily coupled to the crankshaft (14), in order to rotate the eccentric sleeve (40) in relation to the connecting rod (22). This allows a rotation of the crankshaft (14) and the crank pin (30) relative to the connecting rod (22) to be utilized during operation of the internal combustion engine, in order to temporarily entrain the eccentric sleeve (40), thereby rotating said sleeve rapidly and securely from one rotational direction into the other.

    摘要： The invention relates to a drive (1) comprising a piston machine in particular in the form of a combustion engine, said drive having a device for efficiently reducing alternating torques produced by rotational nonuniformities on the basis of the engine speed- and torque pulsation of the combustion engine and the mass forces created by the reciprocating motion of the piston and the connecting rod during operation. For this purpose, a crankshaft (2) of the combustion engine carries a sun wheel (3) of a planetary gearbox (4). In a per se known manner, the planetary gearbox (4) also comprises three planet gears (5, 6, 7) and a ring gear (8). In the embodiment shown, the planet gear (5) is used to drive a balancing shaft (9) which can be driven thereby in the opposite direction. In order to be able to drive, in addition to this balancing shaft (9), also another balancing shaft (10) in the same direction of rotation as the crankshaft (2), the ring gear (8) has, in addition to inner teeth (11) which engage with the planet gears (5, 6, 7), outer teeth (12) for a toothed wheel (13) which drives the second balancing shaft (10), wherein the number of teeth of the inner toothing (11) and of the outer toothing (12) match.
