A holder for fastening at least one component, particularly a fuel distributor, to an internal combustion engine. The holder includes an elastically deformable damping element, a holder body and a spring element, which are situated lying one behind the other with reference to an axis. In response to an assembly using the fastening arrangement, a prestressing of the spring element and a prestressing of the damping element are made possible. Furthermore, a fuel injection system is described having a fuel distributor and such a holder, which is used for fastening the fuel distributor on an internal combustion engine.

The decoupling element for a fuel injection device according to the invention is characterized in particular in that a low noise design is implemented. The fuel injection device includes at least one fuel injector and a receiving borehole in a cylinder head for the fuel injector, and the decoupling element between a valve housing of the fuel injector and a wall of the receiving borehole. The decoupling element is a decoupling system made up of a contoured spring seat on a shoulder of the receiving borehole and a spring washer resting on the shoulder. The fuel injection device is suited in particular for direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignition internal combustion engines.

A holding device is used for fastening a fuel distributor to an internal combustion engine. A plurality of holding elements is provided, which are able to be fixed in place on the internal combustion engine via a fastener. A cable guide is provided in addition. The holding elements are connected to the cable guide. In addition, a system having such a holding device and a fuel distributor for conveying fuel are provided.

An exemplary fastening system includes, among other things, a first component providing a first aperture, a second component providing a second aperture, and a fastener. The fastener has a shaft extending from a head. The shaft extends along an axis through the first aperture and the second aperture to clamp the first component axially between the head and the second component. A compressible sleeve distributed about the shaft is compressed radially by the first component. An exemplary fastening method includes moving a shaft of a fastener along an axis through an first aperture in a first component into a second aperture in a second component, and compressing at least a portion of compressible sleeve radially with the first component. The compressible sleeve is distributed about the shaft. The method further includes clamping the first component between a head of the fastener and the second component.

A fuel injector rail assembly for direct injection of fuel includes an elongate fuel distribution tube, a plurality of fuel injector sockets each formed to contain therein a fuel injection valve and being integrally secured to the fuel distribution tube, and a plurality of brackets each integrally secured to the distribution tube. The brackets each are made of pressed sheet metal and includes a mounting plate portion formed with a bolt hole for mounting the fuel distribution tube on an engine head and an opening for permitting each lower portion of the fuel injector sockets inserting therethrough, a pair of stationary arm portions extended in parallel from one side edge of the mounting plate portion at opposite sides of the respective fuel injector sockets and secured to the distribution tube. An outward flange formed at each lower end of the injector sockets is secured to an underside surface of the periphery of the opening for each injector socket. A central axis of the bolt hole is offset from a central axis of each of the fuel injector sockets in a longitudinal direction of the fuel distribution tube.

A forged fuel rail for a motor vehicle includes a tubular base body, an inlet formed in one piece on the base body and made of a same material as the base body. Further formed in one piece on the base body and made of a same material as the base body are a plurality of injector mounts and, a support element for securement of the fuel rail to a further motor vehicle component. A reinforcement member extends between a corresponding one of the injector mounts and the support element and is formed in one piece on the base body and made of a same material as the base body. The reinforcement member is hereby formed from a flash created during a forging process.

A fuel-piping attachment structure includes a fuel piping, at least one fastening portion, and a protective member. The at least one fastening portion is to be joined to an internal combustion engine main body to support the fuel piping with respect to the internal combustion engine main body. The protective member includes at least one base portion to be joined to the internal combustion engine main body. All of the at least one fastening portion are disposed on a first side in a Z direction with respect to the axis of the fuel piping. All of the at least one base portion are disposed on a second side in the Z direction with respect to the axis of the fuel piping.

An injector has an inlet body. A cup is in a bottomed tubular shape to hold the inlet body. The cup has a sidewall defining first apertures and second apertures. A first pin is inserted in the first apertures. A second pin is inserted in the second apertures. The first pin and the second pin are configured to hold the inlet body and to restrict rotation of the inlet body relative to the cup.

A fuel rail includes a pressure accumulator pipe which is configured to receive fuel under pressure and includes a forged tubular body. Made in one piece with the tubular body is an injector mount. A support arranged on the tubular body extends in alignment with the injector mount, with a screw fastener configured to secure the pressure accumulator pipe via the support to a cylinder head of an internal combustion engine.

A cup is in a bottomed tubular shape to receive an injector along an injector axis. A bracket is extended from a sidewall of the cup. The bracket includes at least one arm and a body. The at least one arm connects the body with the cup. The body forms a screw opening configured to receive a screw along a screw axis. The body has a pivot end on an opposite side of the screw axis from the injector axis.
