Fuel supplying device for internal combustion engine
 The invention relates to a fuel supplying device for an internal combustion engine. A fuel supplying device for an internal combustion engine includes a fuel injector for injecting fuel into a collector or riser section of an intake manifold from which a plurality of branches extend toward cylinders of the engine. According to the invention, an induction passage is bent or provided with an elbow so that induction air will change its direction toward a heated bottom wall of the riser section before entering the same and the fuel injector is arranged so as to inject fuel toward the bottom wall and radially inwardly into a flow of induction air passing through the induction passage. With this the amount of fuel flowing along the riser walls has been considerably reduced, thus enhancing the response characteristics.
