Abstract: A system, which is used in particular as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element, which has a supporting surface. The cup has a contact surface on an underside, by way of which the cup is supported at the supporting surface of the holding element by a damping layer. The holding element is attached to the cup. In addition, the fuel injector has a collar, which is braced on the holding element. Because of the damping layer, vibrations are able to be dampened, and the noise transmissions is able to be reduced.

Abstract: A component, which can be in the form of a fuel line or fuel distributor, is used for a fuel injection system, which is used for injecting fuel or a mixture of fuel and water having a variable water content. The component has a main body on which is provided a high-pressure inlet and at least one high-pressure outlet, the fuel, respectively the mixture being passable from the high-pressure inlet through an inner space of the main body to the least one high-pressure outlet, and an insertion member being configured in the inner space. The insertion member is at least partially made of at least a material having a modulus of compression specified to at least substantially correspond to or be lower than that of the fuel, respectively the mixture and/or lower than 30 GPa.

Abstract: A fuel injection valve of a fuel injection system includes a connector piece that is insertable at least partly into a receiving space of a connector body of a fluid-conveying component. In the installed state a support part is disposed on the connector piece, and the connector piece is mounted via the support part on the connector body. The support part has a spherical support surface with which the support part braces at least indirectly against the connector body in order to implement the mounting of the connector piece directly or indirectly on the connector body.

Abstract: A component for a fuel injection system, in particular a high-pressure fuel injection system, includes a base body which is implemented in a tube-shaped manner at least sectionally. A tubular section of the base body is implemented having a longitudinal bending along a longitudinal axis of the tubular section which perpendicularly intersects the cross sections of the tubular section. At the longitudinal bending of the tubular section, the base body is implemented in such way that an ovality of the cross sections of the tubular section is reduced and/or smaller than 8% at the longitudinal bending.

Abstract: A system, which in particular is used as a fuel injection system for high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each of the fuel injectors is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a retaining clip. The retaining clip has at least one clip section which is situated between an inner side of the cup and an outer side of the fuel injector. Furthermore, at least one damping composite element is provided, which is situated between the clip section of the retaining clip and the outer side of the fuel injector. The damping composite element has an elastically deformable damping layer. A decoupling is thus realized, which acts to damp vibrations and consequently to reduce noise.
