FUEL HEATING SYSTEM AND FUEL RAIL USING THE SAME

Japanese Patent JP2015059537

A

PROBLEM TO BE SOLVED: To provide a fuel heating system which achieves high fuel heating efficiency and efficiently leads a high temperature fuel to a fuel injection valve.SOLUTION: A heating chamber formation part 30 includes: a first wall surface 301; a second wall surface 302 which intersects with the first wall surface 301 at a predetermined angle range including a right angle; a corner part 310 formed between the first wall surface 301 and the second wall surface 302; and a heating chamber 300 which is formed so as to include the corner part 310. An inlet opening part 33 guides a fuel from a fuel tank into the heating chamber 300. An outlet opening part 34 guides the fuel in the heating chamber 300 to a fuel injection valve 10. A heating device 60 includes a heating part 62, which generates heat, and is provided at the heating chamber formation part 30 so that the heating part 62 is positioned in the heating chamber 300. The corner part 310, the inlet opening part 33, and the outlet opening part 34 are formed so as to be positioned above the heating part 62 in a vertical direction in a state where a fuel heating system 100 is attached to an intake manifold 6 near an engine.
