Abstract: A method for balancing the torque generated by the cylinders of an internal combustion engine comprising the stages of: determining for each cylinder quantity which indicates the torque generated by the cylinder in a given engine cycle; determining for each cylinder a nominal fuel amount to be injected in this cylinder in a subsequent engine cycle; determining for each cylinder a correction coefficient of the nominal fuel amount to be injected in the cylinder in this subsequent engine cycle according to the quantity determined for this cylinder; correcting the nominal fuel amount to be injected in each cylinder according to the correction coefficient determined for the cylinder itself; and injecting into each cylinder the corresponding corrected fuel amount.

Abstract: In a multi-cylinder internal combustion engine, equipped with an electronically controlled hydraulic system for the variable operation of the engine's inlet valves, an indicator of the differences in the amount of air aspirated by the cylinders of the engine during the respective induction phase is provided and said system controls the various inlet valves of the engine in a differentiated manner, varying the time and/or opening travel for the purpose of minimizing the differences between the amounts of air aspirated by the various cylinders of the engine.
