摘要： A heat exchanger tube has an inner peripheral surface serving as an exhaust gas flow path with a flat cross-sectional shape. A thin structure is incorporated in the heat exchanger tube and has a substantially rectangular channel-shaped waveform in cross section. The corrugated fin structure has a curved surface forming waveform meandering with a predetermined wavelength in the lengthwise direction. The wave width of the channel-shaped waveform is H, the wavelength of the waveform meandering in the lengthwise direction is L and the amplitude of the waveform meandering in the lengthwise direction is A. The heat exchanger tube is formed so that H/L is set at 0.17 to 0.20 and the ration (G/H) of a gap G determined by H-A to H is set at −0.21 to 0.19.

摘要： 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.
