A fuel rail assembly is disclosed. The fuel rail assembly includes an elongated tubular fuel rail and a plurality of fuel delivery lines for hydraulically coupling the fuel rail to fuel injectors. Each fuel delivery line has an injector cup, a pipe being arranged between the fuel rail and the injector cup, and a fixation bracket. A rigid connection is established between the fixation bracket and a portion of the pipe, the portion being spaced apart from each of the fuel rail and from the injector cup.

The injector cup, the pipe, and the fixation bracket are individual parts. The fixation bracket is spaced apart from the injector cup and from the fuel rail.

A fuel distributor, which is used, in particular, for fuel injection systems of mixture-compressing, internal combustion engines having externally supplied ignition, includes a distributor pipe, a first holder and at least one second holder. The distributor pipe has a longitudinal axis. In this connection, the first holder and the second holder are situated at the distributor pipe so as to be axially set apart from one another with respect to the longitudinal axis. The distributor pipe is designed to allow axial length compensation. It is also possible for at least one holder to be designed to allow axial length compensation.

An object of the present invention is to provide a fuel rail which can realize weight reduction while enhancing the strength of a cross-hole portion. A fuel rail for an internal combustion engine according to the present invention includes a cylindrical fuel rail body 1 and an injector mounting portion 2 in which a hole 2d to supply a fuel to an injector is formed, and the injector is mounted. The injector mounting portion 2 is integrally molded in the fuel rail body 1 such that the fuel supply hole 2d crosses a center hole 1a of the fuel rail body 1. plurality of injector mounting portions 2 is included along a longitudinal direction of the fuel rail body 1. A thickness of a root portion of the injector mounting portion 2 is thicker than a thickness of the fuel rail body 1 disposed between two adjacent injector mounting portions 2.

A monolithic fuel delivery system for gasoline direct injection to an engine. The system has a common rail tube body from which injector sockets smoothly and seamlessly extend. Uninterrupted junctions are formed between the rail tube body and the injector sockets. The seamless junctions present a sealed relationship between the tube body and the injector sockets.

A fuel distributor which has a pressure accumulator pipe for receiving pressurized fuel where the pressure accumulator pipe has a forged main body with a longitudinal cavity. At least one connector flange is configured in one piece from the same material on the main body. The connector flange has an injector connector with a connecting duct to the longitudinal cavity. A cup-shaped injector receptacle is joined to the injector connector. The injector receptacle is a single-piece deep-drawn part or a single-piece extruded part or a single-piece turn-milled part, and is connected to the injector connector by way of a fuel-tight join, or by way of brazing technology.

A fuel distributor for a fuel injection system for mixture-compressing, spark-ignited internal combustion engines. The fuel distributor rail includes a tubular base body which is processed by forging. At the base body, a first high-pressure output, a second high-pressure output, and a third high-pressure output are provided. The second high-pressure output is situated in an offset manner opposite the first high-pressure output in a first direction along a longitudinal axis of the tubular base body at a predefined distance. The third high-pressure output is situated in an offset manner opposite the second high-pressure output in the first direction along the longitudinal axis at the predefined distance. A first and second holding element, which are used for an at least indirect fastening of the base body, are situated at the tubular base body.

To provide an engine head structure for “omission or shortening a fuel pipe that withstands a high pressure”, “simplification or omission of a support bracket for a fuel accumulator and/or a fuel injection device”, “reduction of the number of parts” by devising a fuel accumulator and a support structure therefor, and the like. An engine head structure has a support bracket for mounting a fuel accumulator including a joining portion with a fuel injection device on a cylinder head, is disposed on a side of the fuel injection device or between adjacent fuel injection devices. The support bracket includes a member having a mounting portion on which the fuel accumulator is placed and mounted, a mounting leg portion extending from the mounting portion and mounted on the cylinder head, and an aligning leg portion extending from the mounting portion for positioning the support bracket with respect to the cylinder head.

A fuel distributor which has a pressure accumulator rail for receiving pressurized fuel. The pressure accumulator rail has a forged base body. Mounting supports are joined to the base body by substance bonding. A mounting support is formed by two metal brackets each configured as a sheet-metal formed part. Each metal bracket has a holding portion adapted to the outer contour of the base body, a leg angled relative to the holding portion, and a mounting flange on the free end of the leg and angled away therefrom. A length portion of the base body is received between the holding portions. The holding portions partially surround the base body. The base body and the holding portions are joined by substance bonding. The legs of the two metal brackets lie next to each other at least in regions and are also joined together by substance bonding.

The invention relates to a device (10) for a common rail fuel injection system (102), wherein the device (10) comprises a one-piece module (12) which comprises a common fuel line (14) and a plurality of injector bodies (16) in fluid communication with the common fuel line (14). The present invention also relates to a vehicle (100) comprising such a device (10). The present invention also relates to a method of manufacturing a device (10) for a common rail fuel injection system (102).

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.
