Summary:A combination of a vaporized fuel treating device and a blow-by gas returning device for an engine having a forced induction device may include an ejector. The ejector is disposed in a bypass passage that is in communication with an intake conduit at portions positioned upstream and downstream of the forced induction device. The ejector is configured to receive a boost gas generated by the forced induction device and to generate negative pressures therein, so as to supply the generated negative pressures to a purge conduit of the vaporized fuel treating device and a blow-by gas returning conduit of the blow-by gas returning device.
