Abstract
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.
