Abstract:
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.
