<P>PROBLEM TO BE SOLVED: To provide a fuel rail which prevents interference with other members arranged in an internal combustion engine. <P>SOLUTION: A rail body 21 is formed in a tubular shape, and has an inlet 23 where a fuel from a fuel supply source 11 enters. A plurality of protrusions 24 are formed to protrude, in a tubular shape, from the rail body 21 in a direction substantially perpendicular to an axis Ax1 of the rail body 21, at predetermined intervals in a direction of the axis Ax1 of the rail body 21. An extension portion 25 is formed in a tubular shape to extend from an end of the protrusion 24 opposite to the rail body 21, in a direction substantially perpendicular to the axis Ax2 of the protrusion 24 and to the axis Ax1 of the rail body 21, and is inserted into a bore 4 that connects the outside of an engine 1 with a combustion chamber 2. A connecting portion 28 is formed at an end of the extension portion 25 opposite to the protrusion 24. The connecting portion 28 is connected to one end of a fuel injection valve 50 accommodated in the bore 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
