The fuel distributor includes a tubular base body, which is preferably processed by a one-stage or multi-stage forging process, a first high-pressure output, a second high-pressure output, a third high-pressure output, and a fourth high-pressure output being provided at the base body. The second high-pressure output is situated offset by a predefined distance compared to the first high-pressure output in a first direction along a longitudinal axis of the tubular base body. The third high-pressure output is situated offset by the predefined distance compared to the second high-pressure output along the longitudinal axis in the first direction, the fourth high-pressure output being situated offset by the predefined distance compared to the third high-pressure output along the longitudinal axis in the first direction.

A holder is used for fastening a fuel distributor to an internal combustion engine. The holder has a base element which is connected to the fuel distributor. A slotted sleeve is provided, which is connected to the base element, and the base element is braced on the internal combustion engine via the slotted sleeve. Furthermore, a system having the fuel distributor and a plurality of holders of this type is provided.

A system, which is used especially 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. The holding element has an at least essentially straight first leg and an at least essentially straight second leg. The cup includes at least one recess, which extends through a wall of the cup. The first leg and the second leg are guided through the at least one recess. Furthermore, the connection sleeve of the fuel injector has a collar, which is braced on the first leg of the holding element and on the second leg of the holding element in order to secure the fuel injector on the cup.

System having a fuel distributor and multiple fuel injectors

A fuel injection system has a fuel distributor and multiple fuel injection valves each disposed on a cup of the fuel distributor. At least one injection valve is mounted on the associated cup by way of at least one holding element. An abutment surface is provided on the outer side of the cup. A support surface is configured on the underside of the cup. The holding element is moreover configured as a holding clamp. An abutment surface is provided on an outer side of the fuel injection valve. The holding clamp engages on the one hand behind the abutment surface of the cup and on the other hand behind the abutment surface of the fuel injection valve. The holding clamp furthermore pushes the fuel injection valve toward the support surface.

A bearing bush is for a holder, which is for fastening a component, particularly of a fuel distributor, to an add-on structure. The bearing bush has an inner bush part, which is made of a metallic material, and an outer bush part, which is made of a metallic material, and an elastically deformable damping element. The outer bush part has a continuous recess, in which the inner bush part is situated. The damping element is situated between the inner bush part and the outer bush part. A holder having such a bearing bush is also specified. In addition, a fuel-injection system having a fuel distributor and at least one holder is specified, which is used for fastening the fuel distributor on an internal combustion engine.

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.

A system, which may be embodied particularly as a fuel injection system for high pressure injection in internal combustion engines, includes a fuel distributor and a mounting support, which is used for fastening the fuel distributor to an externally-mounted structure, particularly a cylinder head, of an internal combustion engine. In this case, a damping composite element is provided, which is connected to the mounting support and/or the fuel distributor. The damping composite element includes at least one metal layer, which is formed at least essentially of a metallic material, and at least one elastically deformable damping layer.

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.

The fuel injection device according to the present invention is distinguished by a particularly effective sound-decoupling construction. The fuel injection device has at least one fuel injection valve, a receptacle bore for the fuel injection valve in a cylinder head, and a fuel distributor line having a fitting in which the fuel injection valve is placed in partially overlapping fashion. A connecting element is situated in the receptacle bore in such a way that the fuel injection valve is held in the connecting element in such a way that the fuel injection valve and the connecting element are held so that they do not contact any surfaces or walls of the receptacle bore of the cylinder head that do not run axially parallel to the fuel injection valve. The connecting element is attached immediately on the fitting of the fuel distributor line. The fuel injection valve is particularly well-suited for use in fuel injection systems of mixture-compressing externally ignited internal combustion engines.
