    摘要： A fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine includes an energizable actuator, a valve needle, which is in operative connection with the actuator and acted upon by a restoring spring in a closing direction to actuate a valve-closure member, which, together with a valve-seat surface formed on a valve-seat body, forms a sealing seat; and includes at least two spray-discharge orifices which are formed in the valve-seat body. At an outer side, facing the combustion chamber of the internal combustion engine, of the valve-seat body, a coating is formed and/or the maximum number of spray-discharge orifices is eight and/or a clearance between the valve-closure member and the valve-seat body is smaller than 20 μm and/or the spray-discharge orifices widen in a spray-discharge direction of the fuel.

    摘要： A fuel injection system (1) for the targeted injection of fuel, comprising a fuel injection valve (2) having a solenoid coil (3), which cooperates with an armature (5) supplied by a return spring (4), the armature forming an axially displaceable valve part together with a valve needle (6), and a control device (9). The control device (9) defines an opening phase (10) having a first holding current (12), and a closing phase (11) beginning after the opening phase (10) and having a second holding current (13) for the fuel injection valve (2), wherein the current characteristic in the solenoid coil (3) is defined during the closing phase (11) of the injection valve (2) such that the magnetic field generated by the second holding current (13) flowing through the solenoid coil (3) brings about a certain magnetic force, such that the valve needle (6) thus experiences a defined stroke (14) that is different from zero, and steadily maintains the same over a defined period of time.

    摘要： A fuel-injection system including a fuel injector, having a plurality of spray-discharge orifices, which meters fuel into a combustion chamber of an internal combustion engine, has an ignition device, which projects into the combustion chamber, this ignition device having at least one first pole and one second pole. The fuel jets emerging from the spray-discharge orifices spread an essentially cone-shaped fuel fan below the region of the ignition device. The end of the at least one first pole is arranged to the side adjacent to the end of the second pole projecting into the combustion chamber, and both ends are located on approximately the same level of the longitudinal axis of the ignition device.
