Zusammenfassung: | A high-pressure fuel injection pipe, which has an outside diameter (phi) of 6.35 mm, an inside diameter (phi) of 4.35 to 2.95 mm, and a wall thickness (t)of about 1.0 to 1.7 mm, can serve as a high-pressure fuel injection pipe for in-cylinder injection type gasoline engines which have an injection pressure of 4 to 20 MPa, and can adequately endure the use of low-grade gasoline, sour gasoline, DME (dimethyl ether), alcohol, alcohol blended fuel, etc. is provided. The high-pressure fuel injection pipe is manufactured by joining an outer pipe which is an seam-welded pipe or a seamless pipe and an inner pipe which is an seam-welded pipe with a Ni or Ni base alloy film on its inner peripheral surface, closely adhering them together by means of elongation. |
