Abstract

A method for controlling the overpressure in a fuel-supply system of a common-rail type for an internal-combustion engine (2) provided with a number of cylinders (3); the method has the steps of: supplying fuel under pressure to a common rail (5) connected to a number of injectors (4) by means of a high-pressure pump (6); detecting the effective value of the pressure of the fuel within the common rail (5); comparing the effective value of the pressure of the fuel within the common rail (5) with a safety value; determining a condition of emergency if the effective value of the pressure of the fuel within the common rail (5) is higher than the safety value; and driving, in the case of emergency, the injectors (4) for discharging part of the fuel present in the common rail (5) so as to contain the increase in pressure of the fuel within the common rail (5).
