Title:
FUEL RAIL
Document Type and Number:
Japanese Patent JP2015031189
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel rail that has high heating efficiency of fuel and can reduce pulsation of the fuel.SOLUTION: An upper member 30 is formed into a long plate shape. A lower member 40 is formed into a long plate shape, and jointed to the upper member 30 so that a longitudinal direction and a transverse direction correspond to the upper member 30 and it is overlaid in a plate thickness direction, and has a fuel flow passage formation part 44 indented to a face side opposite to the upper member 30 from a face on the upper member 30. A fuel flow passage 400 through which fuel flows is formed between the fuel flow passage formation part 44 and the upper member 30. Plural heating chamber formation parts 50 are provided on the upper member 30 outside the fuel flow passage 400, and have inlet openings 54 for introducing the fuel in a heating chamber 500 and the fuel flow passage 400 into the heating chamber 500, and outlet openings 55 for introducing the fuel in the heating chamber 500 to a fuel injection valve 10. A heating device 60 has a heating part 62 that can be heated, and the heating part 62 is provided at the heating chamber formation part 50 so that it is positioned in the heating chamber 500.
