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.

In some embodiments, a fuel rail for a two-stroke internal combustion engine includes a fuel rail body, a fuel inlet component integrated within the fuel rail body as a one-piece component and in fluidic contact with a fuel line, one or more fuel exit ports in fluidic contact with a cylinder of a combustion engine, and one or more fasteners adapted to secure the fuel rail body to a cylinder wall of the cylinder of the combustion engine

The present invention relates to a method for producing an internally pressurized component (1), having the steps of: providing a main body (2) with a longitudinal cavity (3) and with an attachment flange (6) for attachment of the internally pressurized component (1), providing a (80), introducing a through-bore (7) that extends longitudinally through the attachment flange (6) and has two opposite openings (70, 71) with respect to the longitudinal axis (L7), inserting the pin (80) into the through-bore (7) such that the pin (80) is arranged flush with the attachment flange (6) on the side of one of the openings (70) and extends from this opening (70) through the through-bore (7) and through the other opening (71) in order to project from the attachment flange (6), materially bonding the pin (80) to the attachment flange (6), and introducing a longitudinal bore (81) into the pin (80) to form an attachment sleeve (8). The invention also relates to a corresponding internally pressurized component (1).

An engine device including a common rail configured to store, at a high pressure, a fuel supplied by a fuel feed pump. The common rail includes a pressure reducing valve configured to discharge the fuel in the common rail to a fuel return pipe. The fuel return pipe extends from the pressure reducing valve to a position higher than the pressure reducing valve, and then extends to a position lower than the pressure reducing valve.

A fastener assembly for connecting a fuel pipe to an engine component. The fastener assembly includes a housing and a fastener positioned within the housing. The housing has an end surface with an aperture for receiving a fuel pipe therethrough. At least one side wall extends from the end surface to define a recess for receiving a fastener therein. The fastener has a pipe inlet for receiving a fuel pipe therethrough, and a connecting arrangement for connecting the fastener to an engine component.

An assembly for fuel-injection systems for connecting a fuel injector to a fuel-conveying component includes a retaining part that is used for mechanical fastening, and an attachment part, to which the fuel injector is hydraulically connectable. A connecting part is provided via which the attachment part, that is connectable to the fuel-conveying component, is connectable to the retaining part.

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 present invention aims for obtaining a fuel rail for gasoline direct injection which can be used for the direct injection at a high fuel pressure of 50 MPa or more by increasing the thickness at the portion near the branch hole and using the material having high thickness for the metal seal portion while keeping the weight light and keeping the cost low. A fuel rail for gasoline direct injection made of steel and used at a fuel pressure of 50 MPa or more, the fuel rail having: a plurality of block members 2; and a pipe member 1 which connects an interval between the block members, wherein the block members 2 have: a branch hole 3 which communicates with the pipe member 1; and a metal seal portion 6 to which an injector is connected, and the hardness of the block members 2 is higher than the hardness of the pipe member 1.
