FIELD: engines and pumps.
SUBSTANCE: invention relates to a method for controlling a quantity control valve of a high-pressure pump for internal combustion engine. Said result is achieved by the following, in the fuel injection system (10) into the internal combustion engine, fuel is delivered by a high-pressure pump (16) into a high-pressure fuel rail (18). Quantity of the delivered fuel is influenced by a quantity control valve (30), actuated by an electromagnetic actuating device (34). According to the invention, a limit-value holding current is determined in which the quantity control valve is still in its closed state or just opening.
EFFECT: technical result consists in improving the control of the quantity control valve with an improving its noise characteristic.
