摘要： Disclosed is a fuel injection valve (1) for directly injecting fuel into a combustion chamber (39) of an internal combustion engine. Said fuel injection valve (1) comprises an excitable actuator (10), a valve needle (3) that is effectively connected to the actuator (10), is impinged upon by a return spring (23) in a closing direction, and actuates a valve closing member (4) which forms a sealing seat along with a valve seat area (6) embodied on a valve seat member (5), and at least two spray ports that are configured inside the valve seat member (5). A coating (38) is embodied on an external face (37) of the valve seat member (5), which faces the combustion chamber (36) of the internal combustion engine, and/or the maximum number of spray ports (7) provided is eight, and/or a distance between the valve closing member (4) and the valve seat member (5) is smaller than 20 ñm, and/or the spray ports (7) expand in a fuel-spraying direction.

摘要： Disclosed is a fuel injection valve (1) comprising an actuator which is effectively connected to a valve needle (3). The discharge end of said valve needle (3) is provided with a valve-closing member (4) which cooperates with a valve seat surface (6) so as to form a sealing seat. A discharge port (7) ends at an outlet point (46). Said outlet point (46) of the discharge port (7) protrudes relative to all sides of the surface which surrounds the outlet point (46) and from which the same extends.

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 fuel 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 (1) comprising a fuel injection valve (2) which is provided with several injection openings (13) and which enables fuel to be injected into a combustion chamber (6) of an internal combustion engine, comprising an ignition device (8) which protrudes into the combustion chamber (6) and has at least one first pole (16) and one second pole (17). The fuel jets (20) exiting from the injection openings (13) form a substantially conical envelope shaped fuel fan (11). The end of the at least one first pole (16) is arranged to the side close to the end of the second pole (17) which protrudes into the combustion chamber (6). The two ends are located at approximately the same level of the longitudinal axis of the ignition device (8).
