A fluid distributor for an injection system, in particular a fuel distributor rail for a fuel injection system for mixture-compressing, spark ignition internal combustion engines. 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 connector for mounting a sensor such as a pressure sensor in a fuel system includes a connector body and a tube body. The tube body has sealing surfaces at opposite axial ends that are structured to bias rotation of the connector body and the tube body to occur relative to one another rather than the connector body causing the tube body to rotate against a housing of a fluid reservoir in the system. Deformation of the housing is limited by way of the biasing of rotation.

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

In one aspect, a system for coupling a fuel rail of a common rail fuel system to an internal combustion engine may include an engine wall having a plurality of openings. The fuel rail may have a main pipe portion located outside the engine wall, and a plurality of outlet pipes monolithically formed with the main pipe portion, each of the plurality of outlet pipes extending into a corresponding one of the plurality of openings of the engine wall. The system may further include a seal located in sealing engagement with each of the plurality of openings and a corresponding outlet pipe.

A pipe section of a common rail line is provided for the high-pressure injection of a fluid. The pipe section has at least a first pipe and an adapter in which the first pipe has a wall and extends at least along an axial direction. The wall has an inner circumferential surface and an outer circumferential surface and encloses a first line. The adapter has a connector piece and a second pipe. The connector piece extends annularly around the first pipe and is situated on the outer circumferential surface. A second line that is formed by the second pipe is fluidically connected to the first line via a first opening in the first pipe and a second opening in the connector piece. At least the adapter is manufactured by a metal powder injection molding process. Two methods for manufacturing a pipe section are also provided.

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 connection assembly is used to connect a first body to a second body. The first body includes a bore that is coaxial with a first axis, and a retainer opening that extends coaxially with a second axis. The second axis is perpendicular to the first axis and offset relative to the first axis. In addition, a portion of the retainer opening intersects the bore. The second body includes an insertion portion that is disposed in the bore, a fluid passage that extends through the insertion portion and communicates with the bore, and an outer surface of the second body has a channel. The connection assembly employs an elastic retaining pin that retains the insertion portion within the bore. The retaining pin is disposed in the retainer opening such that a portion of the retaining pin resides in the channel, and the retaining pin is self-aligning and self-retaining.

The invention relates to a connecting piece for a fuel injector of an internal combustion engine comprising at least one high-pressure input port and at least one high-pressure output port, wherein the high-pressure input port and the high-pressure output port open into an internal high-pressure accumulator of the connecting piece and/or the injector via separate high-pressure feed channels.

A component (3; 3′) for an injection system (1), in particular a high-pressure line (5) or a fluid distributor (2), including a base body (14; 13), at which a high-pressure input (15; 12) and at least one high-pressure output (16 through 19; 12′) are provided, at least the base body (14; 13) being at least essentially formed from an austenitic or martensitic material. It is provided that the material is developed as a grain-stabilized material.

A fuel conduit connection assembly for interconnecting fuel system components of an internal combustion engine (ICE) system. The fuel conduit connection assembly includes a mounting structure for fastening a portion of the assembly to an ICE external structure; a fuel receiving conduit portion having a plurality of inlet fuel duct connections for connecting to a plurality of corresponding fuel channels of a fuel system component outside the ICE external structure, respectively; a single fuel feeding conduit portion for connecting to a fuel system component internal the ICE external structure; and a sealing arrangement arranged on an outer circumferential surface of the assembly and configured to provide sealing between a first environment and a second environment in an assembled state with the ICE external structure.
