Abstract
A control method for a direct fuel injection system into an internal combustion engine provided with a number of cylinders; the method presents the stages of: supplying pressurised fuel to a common rail by means of a high-pressure pump; cyclically driving a number of hydraulically actuated injectors having an hydraulically actuated needle to inject fuel into the cylinders; establishing a desired fuel pressure level within the common rail; determining a threshold value for the injectors so that no fuel is injected by each injector if it is driven for a time interval shorter than the threshold value; and reducing the actual fuel pressure within the common rail by driving the injectors for a driving time interval shorter than the threshold value.
