供給装置。 In a fuel supply device that detects the absolute pressure in the intake pipe of an internal combustion engine as a parameter for fuel supply amount control, there is a pressure introduction passage that communicates the intake pipe with a pressure sensor that detects the pressure, and a pressure introduction passage that is located in the middle of this pressure introduction passage. A fuel for an internal combustion engine, comprising a switching valve that selectively switches a pressure sensor to either the intake pipe or the atmosphere side, and a control means that switches and drives the switching valve depending on the engine operating state. Feeding device.
