Abstract

A fuel supply device for an internal combustion engine having an intake manifold includes a throttle body defining therein an intake passage communicating at one end thereof with the intake manifold. A flow accelerating valve arranged in the intake passage upstream of a throttle valve cooperates with the wall surface of the intake passage to define a flow accelerating passage of a smaller flow area than the intake passage. The flow accelerating valve is angularly movable in response to a change in the intake fluid flow between a fully closed position in which the flow accelerating passage has a minimum flow area and a fully open position in which the flow accelerating passage has a maximum flow area, to thereby control the flow area of the flow accelerating passage. A fuel injector injects liquid fuel into the accelerated intake fluid flow passing through the flow accelerating passage.
