Abstract
Method for the identification of a torque delivery imbalance of an internal combustion engine equipped with two or more cylinders under constant speed operating conditions of the internal combustion engine comprising an analysis procedure in the frequency domain of a rotation speed signal of said engine so that when an amplitude of a half-order frequency exceeds a predetermined threshold, the cylinder of said two or more cylinders that causes said imbalance is identified by calculating a relative phase.
