ABSTRACT:
An evaporated fuel discharge suppressing apparatus includes a main purge conduit and a bypass purge conduit. The main purge conduit connects a canister and an intake conduit of an engine downstream of a throttle valve, and a purge control solenoid valve is installed in the main purge conduit. The bypass purge conduit bypasses the purge control solenoid valve. Even if the purge control solenoid valve sticks in a closed position, evaporated fuel adsorbed by the canister can flow into the intake conduit of the engine through the bypass purge conduit so that the evaporated fuel in the canister is not discharged into the atmosphere.
