摘要： In a drive unit of a fuel injection device, an electric current is supplied to the fuel injection device by applying a high voltage to the fuel injection device from a high voltage source whose voltage is boosted to a voltage higher than a battery voltage at the time of opening a valve of the fuel injection device. Thereafter, the electric current supplied to the fuel injection device is lowered to a current value at which a valve element cannot be held in a valve open state by stopping the applying of the high voltage from the high voltage source. Thereafter, in a stage where a supply current is switched to a hold current, another high voltage is applied to the fuel injection device from the high voltage source.

摘要： The invention relates to a method and device for the control of a solenoid valve for fuel injection in an internal combustion engine. The control phase thereof is divided into an operating phase (TA), during which the one valve needle of the solenoid valve is held open by a current (IA), flowing through the solenoid coil thereof and a hold phase (TH), during which the valve needle is held open by a second, lower current (IH), flowing through the solenoid coil. At least once at the beginning of the operating phase (TA), a booster phase (B1) is activated, whereby a pulse shaped booster current (IBOOST) flows through the solenoid coil from a booster condenser charged to a high voltage (UBOOST). The invention is characterised in that, during the control phase of the solenoid valve, several booster impulses (B1, B21, B22) are activated sequentially, at freely selectable times during the control phase.
