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.

Fuel supply device

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 (U) a lower face filter cloth (L) of the fuel filter () at a welded portion (C). A sub tank upper side member (U) and a sub tank lower side member (L) nip the upper face filter cloth (U) and the lower face filter cloth (L) at a nipping position NP that is at a different position from the welded portion (C).

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 S), and calculates the change retarding time t(Step S) 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 S).

An air intake device of an internal combustion engine which is capable of enhancing the air intake efficiency and reducing the size is provided. The internal combustion engine includes a cylinder head, an intake manifold provided at a longitudinal side surface of the cylinder head, and a head cover provided on the cylinder head. The air intake device of the internal combustion engine includes an air cleaner including an upper casing and a lower casing detachably coupled to each other and incorporating a filter element, an atmospheric air introduction pipe for introducing air to the air cleaner, and an intake pipe extending from the air cleaner to the intake manifold.
