Abstract: A method for controlling an internal combustion engine (1) comprising a number (W) of cylinders (3); the control method comprises determining the total target torque (Ci—obj) required to be delivered for the operation of the internal combustion engine (1); determining a number (Wa) of active cylinders (3) to be controlled in use for injection and combustion; while a number (Ws) of cylinders (3) are not active and are not controlled for injection and combustion, but only for aspirating an air mass; determining the required target torque (Ci—obj) to be delivered for the operation of the internal combustion engine (1) for each of the active cylinders (3); and controlling the internal combustion engine (1) as a function of the required target torque (Ci—obj) to be delivered for the operation of the internal combustion engine (1) for each of the active cylinders (3).

Abstract: A method for controlling an internal-combustion engine comprises steps of: determining a current value of a driving torque requested to the internal-combustion engine and a first time derivative of the current value of the driving torque; comparing the current value of the driving torque and first time derivative with first and second threshold values, respectively; determining a “sports driving” condition only if the current value of the driving torque is higher than the first threshold value and the first time derivative is higher than the second threshold value; and controlling the internal-combustion engine as a function of the “sports driving” condition.

Abstract: A method to determine the mass of air trapped in each cylinder of an internal combustion engine, which comprises determining, based on a model using measured and/or estimated physical quantities, a value for a first group of reference quantities; determining, based on said model, the actual inner volume of each cylinder as a function of the speed of rotation of the internal combustion engine and of the closing delay angle of the intake valve; and calculating the mass of air trapped in each cylinder as a function of the first group of reference quantities and of the actual inner volume of each cylinder.
