Abstract
A saddled vehicle includes: a fuel injection valve mounted in a cylinder head from one side surface of the cylinder head and injecting fuel toward a combustion chamber; and a fuel pump that supplies fuel to the fuel injection valve in response to a generated pump pressure. The fuel pump is disposed in a space between main frames and a down frame and in the one side surface of the cylinder head. Accordingly, there is provided a layout of the fuel pump capable of sufficiently protecting the fuel pump without a need to restrict a position of an internal combustion engine.
Claims23
A saddled vehicle comprising:
- main frames extending rearwardly from a head pipe;
- a down frame extending downwardly from the head pipe into a space below the main frames;
- a crankcase disposed between the main frames and the down frame;
- a cylinder block including a piston, the cylinder block coupled with the crankcase;
- a cylinder head coupled with the cylinder block and defining a combustion chamber between the cylinder head and the piston;
- a fuel injection valve for injecting fuel toward the combustion chamber, the fuel injection valve supported on and mounted within the cylinder head from a lateral side surface of the cylinder head;
- a primary fuel pump disposed inside a fuel tank;
- and
- a secondary fuel pump that supplies fuel to the fuel injection valve in response to a pump pressure generated by the primary fuel pump,
- wherein the secondary fuel pump is disposed at least partially within the lateral side surface of the cylinder head and above the fuel injection valve, and
- wherein, as seen in a side view of a projection plane orthogonal to a rotational axis of a crankshaft that is rotatably supported within the crankcase, the secondary fuel pump is arranged at a position such that at least an uppermost rear portion of the fuel injection valve is overlapped with the secondary fuel pump in an up-and-down direction.
