FUEL RAIL FOR HIGH-PRESSURE DIRECT INJECTION INTERNAL COMBUSTION ENGINE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED The present invention is directed to provide a high-quality fuel rail for high-pressure direct-injection internal combustion engines, in which an injector holder and a fastening bracket are directly attached to a main body of the fuel rail, and has advantage that even if thermal deformation occurs at the time of temporary fitting or brazing when assembling the rail, positional accuracy of the injector holder can be assured, which results in having an excellent sealing property. MEANS TO SOLVE THE PROBLEM The present invention also relates to a fuel rail for high-pressure direct-injection internal combustion engines, in which components of the fuel rail for direct-injection internal combustion engines are made of steel or stainless steel, and the components are reciprocally joined by brazing, characterized in that the components joined by brazing are finished by cutting work and/or burnishing processing after the brazing step.
