Abstract: A fuel supply device is obtained in which joint strength can be maintained in a joint portion of plural filter members configuring a fuel filter. A fuel filter with an overall bag shape is configured by welding together an upper face filter cloth a lower face filter cloth of the fuel filter at a welded portion. A sub tank upper side member and a sub tank lower side member nip the upper face filter cloth and the lower face filter cloth at a nipping position that is at a different position from the welded portion.

Abstract: Recirculation piping that recirculates fuel discharged from a fuel pump to an intake side of a fuel pump in a fuel tank is provided. In addition, a canister is formed with a heat transfer surface that guides fuel flowing through the fuel tank during actuation of the fuel pump. When the recirculation piping recirculates the fuel discharged from the fuel pump into the fuel tank, the heat transfer surface transfers heat between the canister and the fuel discharged from the fuel pump among fuel in the fuel tank.

Abstract: If it is determined that an internal temperature Tc of a canister that is formed with a heat transfer surface for guiding fuel that flows through a fuel tank during actuation of a fuel pump is lower than a specified temperature To (step S1), the ECU determines whether a driving voltage of the fuel pump is a high driving voltage (step S2). If it is determined that the driving voltage of the fuel pump is not the high driving voltage, an FPC is controlled, and the driving voltage of the fuel pump is increased (step S3, S5). Accordingly, a current that flows through the fuel pump is increased, so as to heat discharged fuel.

Abstract: The fuel supply apparatus optimizes the timing of performing the fuel pressure change indication and the fuel injection timing to suppress the real fuel injection amount from being differentiated from the target fuel injection amount even at the time of the fuel pressure being changed, thereby improving fuel consumption. The ECU judges that the fuel pressure change request is generated (“YES” in Step S11), and calculates the change retarding time t1 (Step S12) when the fuel pressure is at the low pressure side, and the ECU determines that the vehicle is in the warming-up state, or that the fuel is at the high temperature. The ECU sets the change timing to avoid the timing of injecting the fuel from overlapping the changing timing of the fuel pressure with reference to the injection timing of the fuel injection control (Step S13).
