<p>A balancing method of the cylinders (2) of an internal combustion engine (1); the balancing method includes the steps of: determining, during a design phase, a first investigation window (Wa) associated to a first cylinder (2a); determining, during the design phase, a second investigation window (Wb) associated to a second cylinder (2b); sampling, during an engine cycle, the measure of the instantaneous intake pressure provided by at least one pressure sensor (13) coupled to at least one intake duct (3); determining a first balance index (Ia) associated to the first cylinder (2a) by calculating an average of the instantaneous intake pressures within the first investigation window (Wa); determining a second balance index (Ib) associated to the second cylinder (2b) by calculating an average of the instantaneous intake pressures within the second investigation window (Wb); and determining the degree of unbalance of the two cylinders (2) according to the balance indexes (Ia, Ib).</p> |
