A method and an arrangement for reducing vibrations in an internal combustion engine (2) which has a plurality of drive units (3-8) connected to a common output shaft (9). These are equipped with a combustion chamber and inlets (34-39) for fuel from organs for fuel supply. Any one of the driving units (7) can be switched from a normal operating condition to an alternative operating condition, in which the supply of fuel to the drive unit is blocked, which causes an alteration in the torque of the driving unit which has been thus switched. The amount of fuel supplied to the drive units which are in a normal operating condition is distributed according to a chosen pattern in order to create torques in these which cause a chosen suppresion of vibrations.

[ What is claimed is:] [1.]1. A method for reducing vibrations in an internal combustion engine which has a crankshaft, at least three cylinders each having at least one inlet for fuel and units for fuel supply, the at least three cylinders including at least two cylinders having a normal operational state, during which the at least two cylinders are supplied with fuel, at least one cylinder of the at least three cylinders having a normal operational state, during which the at least one cylinder is supplied with fuel, and an alternative operational state, during which the at least one cylinder compresses air and during which the supply of fuel to the at least one cylinder is blocked, causing a change of torque transferred to the crankshaft, the method comprising:a) distributing the amount of fuel supplied to the at least two cylinders according to the torque for each of the at least two cylinders required to suppress vibrations when the at least one cylinder is in the alternative operational state.
