METHOD FOR CONTROLLING A MAGNETIC VALVE OF A RATE CONTROL IN AN INTERNAL COMBUSTION ENGINE

摘要

A method for regulating a fuel injection system of an internal combustion engine, wherein the fuel injection system includes a high-pressure pump which is associated with a quantity control valve having a solenoid valve electromagnetically operable by a coil for supplying fuel, the quantity control valve regulating the fuel quantity pumped by the high pressure pump and the coil of the solenoid valve being energized according to a setpoint current value in order to close the valve for supplying fuel to the high-pressure pump; when the solenoid valve closes, the setpoint current value is reduced from a first current setpoint value to a second current setpoint value so that an emission of audible noise generated when the solenoid valve closes during operation of the internal combustion engine is at least partially reduced.
