とする内燃機関の燃料供給装置。 A vaporized fuel supply device is provided, which includes a bench lily formed in the middle of an intake passage of an engine, and a mixture passage that branches off the intake passage and opens at the throat portion of the bench lily, and supplies vaporized fuel to the middle of this mixture passage. A flow velocity sensor is provided on the upstream and downstream sides of the vaporized fuel supply device in the mixture passage to detect the intake air flow velocity, and the detection signal of the flow velocity sensor is read to determine the rate of change in intake air velocity upstream and downstream of the vaporized fuel supply device. 1. A fuel supply system for an internal combustion engine, comprising means for calculating and means for feedback controlling the fuel supply amount of the vaporized fuel supply system so that the rate of change in speed coincides with a target value.
