The usual relatively long induction passage connecting the compressor of a supercharger between the carburetor and the intake manifold of an internal combustion engine is bypassed during idling condition by a relatively small idle mixture transfer passage which directs the idling fuel/air mixture directly against a heated section of the intake manifold, thereby preventing precipitation of the fuel during idling. An opening between a part of the induction passage upstream from the compressor and a portion thereof downstream from the compressor limits the boost pressure developed by the compressor to a predetermined upper limit.
