An objective of the present invention is to provide a fuel rail that can be used at a high fuel pressure of 50 MPa or more, for example, has good engine mountability, and has improved material yield. The present invention is regarding a fuel rail including a main pipe portionextending in a longitudinal direction and a plurality of distribution pipe portions, andbranching from the main pipe portion in a cross direction, in a fuel supply system in which a fuel compressed by a fuel pump passes through a fuel passage hole of the fuel rail fixed to an engine trough a bracket or a stay, the fuel is supplied to injectors, and the fuel is injected into the engine, the present invention is to cut and form the main pipe portionand the plurality of distribution pipe portions, andfrom a same single-sheet plate, the single-sheet plate being a plane plate or a flat plate having an irregular shape in cross section, and to seamlessly configure a main pipe hole, distribution pipe holes, and, and injector attaching holes, and, without joints.

Fuel rail and method of manufacturing same

A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop.

High pressure fuel pipe construction for an internal combustion engine

A fuel system component for a direct injection internal combustion engine. The component includes a fuel rail and a plurality of direct injection fuel injectors which are rigidly attached to the rail. Each fuel injector has an elongated body as well as a harness assembly extending laterally outward from the elongated body. Each injector is attached to the fuel rail such that, when viewed along an axis of the fuel injector body, the fuel rail overlies at least a portion of the injector body and at least a portion of the harness assembly.
