| 20110108005 | FUEL RAIL FOR HIGH-PRESSURE DIRECT-INJECTION INTERNAL COMBUSTION ENGINES AND METHOD FOR MANUFACTURING THEREOF - A fuel rail for high-pressure direct-injection internal combustion engines has an injector holder and a fastening bracket directly attached to a main body of the fuel rail. Thermal deformation may occur at the time of temporary fitting or brazing when assembling the rail. However, positional accuracy of the injector holder can be assured, which results in having an excellent sealing property. Components of the fuel rail for direct-injection internal combustion engines are made of steel or stainless steel, and the components are joined reciprocally by brazing. The components joined by brazing are finished by cutting work and/or burnishing processing after the brazing step. | 05-12-2011 |
