发明名称 METHOD FOR CONTROLLING A SOLENOID VALVE OF A QUANTITY CONTROLLER IN AN INTERNAL COMBUSTION ENGINE
摘要 A method for controlling a fuel injection system (10) of an internal combustion engine. Including a high-pressure pump (16) associated with a quantity controlling valve (15) having a solenoid valve (22) electromagnetically actuatable by a coil (21) for supplying fuel, the quantity control valve (15) controlling the quantity of fuel supplied by the high-pressure pump (16) and the coil (21) of the solenoid valve (22) having a first current value applied thereto, in order to close the same for supplying fuel to the high-pressure pump (16), the first current value being reduced to a second current value when the solenoid valve is closing (22), such that the radiation of audible sound arising from the closing of the solenoid valve (22) is at least partially reduced.
