Apparatus for injecting fuel into the intake assembly of a multi-cylinder internal combustion engine, the intake assembly including an intake manifold communicating with cylinder intake ports, an intake passage connected to the manifold, and a supercharging compressor in the intake passage. The fuel injection apparatus comprises a distributor for injecting fuel into the manifold adjacent the intake ports, a center injection line for injecting fuel into the intake passage upstream of the compressor, and a controlled valve for supplying fuel primarily to the distributor at lower engine speeds, and for supplying a progressively larger portion of the fuel into the center injection line with increasing engine load.
