A description is provided of a method for balancing the torque generated by the cylinders (4) of an internal combustion engine (1), comprising the stages of: determining for each cylinder (4) quantity (CB4) which indicates the torque generated by the cylinder (4) in a given engine cycle; determining for each cylinder (4) a nominal fuel amount (QN) to be injected in this cylinder (4) in a subsequent engine cycle; determining for each cylinder (4) a correction coefficient (CL) of the nominal fuel amount (QN) to be injected in the cylinder(4) in this subsequent engine cycle according to the quantity (CB4) determined for this cylinder (4); correcting the nominal fuel amount (QN) to be injected in each cylinder (4) according to the correction coefficient (CL) determined for the cylinder (4) itself; and injecting into each cylinder (4) the corresponding corrected fuel amount (QC).
