A fuel injector for fuel-injection systems of internal combustion engines. The valve includes an electromagnetic actuating element having a solenoid coil, a fixed core, an outer magnetic-circuit component and a movable armature to actuate a valve-closure member which cooperates with a valve-seat surface provided on a valve-seat member. The valve is characterized by its extremely small outside dimensions. The entire axially movable valve needle, including armature and valve-closure member, has a mass of only m&#x3c;=0.8 g. The valve is suitable as a fuel injector, especially for use in fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

Fuel injector

A fuel injector for fuel injection systems of internal combustion engines includes a solenoid coil; an armature acted upon in a closing direction by a restoring spring; and a valve needle, which is connected to the armature in force-locking manner and on which a valve-closure member is formed, which forms a sealing seat together with a valve seat surface. The armature strikes against a stop face of an inner pole of the solenoid coil by way of a stop face, and the armature stop face is provided with a coating. The coating has a surface structure.

Fuel injection valve

A fuel-injection system for injection of fuel into an internal combustion engine includes at least one fuel injector and a first fuel-distributor line which is connected to the at least one fuel injector. A second fuel-distributor line is provided which is connected to the at least one fuel injector via an individual corresponding lance.

Fuel-injection system and method for injecting fuel

An atomizer nozzle () for fuels, in particular for feeding them into a chemical reformer for obtaining hydrogen, has a nozzle body () containing spray-discharge orifices () that discharge into a metering space, and has at least one metering aperture (). The spray-discharge orifices () are situated at elevation levels () so as to have a radial directional component with respect to a center line () of the nozzle body (), each elevation step having at least one spray-discharge orifice (), and the spray-discharge orifices () of at least one elevation level () being connected to at least one channel () of a nozzle-body insert () that has at least one flow-through opening ().

Atomising nozzle

A dual component injector, especially for internal combustion engines, has a nozzle body, which has a nozzle outlet, and a valve needle for opening and closing the nozzle outlet. A first feed channel is used for supplying a first fluid to the nozzle outlet, and a second feed channel is used for supplying a second fluid to the nozzle outlet. Optionally, a fluid chamber, which is located in the nozzle body, is connected to the nozzle outlet. The second feed channel is connected to the fluid chamber or to the first feed channel via at least two bored holes. The bored holes open out in the fluid chamber or in the first feed channel in such a way that the second fluid produces a swirling flow pattern in the fluid chamber or in the first feed channel.
