Abstract:
1. A control method of a direct injection system of the common rail in an internal combustion engine; the control method comprises the steps of: feeding the pressurized fuel to a common rail by means of a high-pressure pump presenting at least one pumping element mechanically operated by a drive shaft of the internal combustion engine; measuring the angular position of the drive shaft; measuring the fuel pressure (P analyzing the oscillations of the fuel pressure (P determining phase of the pumping element of the high-pressure pump with respect to the drive shaft according to the oscillations of the fuel pressure (P wherein the step of determining the phase of the pumping element of the high-pressure pump with respect to the drive shaft comprises the further steps of: determining the angular position of the drive shaft at which the fuel pressure (P wherein the step of determining the angular position of the drive shaft in which the fuel pressure (P
