A fuel injection valve includes a cylinder internal pressure sensor disposed in the vicinity of a distal end thereof. The cylinder internal pressure sensor detects a cylinder internal pressure in a cylinder and outputs a first sensor signal Ss1 responsive to the detected cylinder internal pressure. Further, a signal processor, which carries out predetermined signal processing with respect to the first sensor signal Ss1 to thereby convert the first sensor signal Ss1 into a second sensor signal Ss2, is disposed between the cylinder internal pressure sensor and a solenoid unit, which is disposed on a proximal end side of the fuel injection valve.

Fuel injection valve

A vehicle fuel supply device including a saddle-shaped fuel tank comprised of a main chamber and an auxiliary chamber. A reservoir is disposed within the main chamber. A main pump is provided within the reservoir. A sub-pump is detachably provided within the reservoir. The fuel in the reservoir is drawn up by an operation of the main pump to supply fuel to an engine. A portion of the drawn-up fuel is utilized to generate a negative pressure, the negative pressure is utilized to transfer the fuel in the auxiliary chamber to the reservoir, and the negative pressure is utilized to introduce the fuel in the main chamber into the reservoir.
