ABSTRACT:
In an engine with a supercharger, there is provided an evaporated fuel processing apparatus for collecting vapor generated in a fuel tank into a canister and purging the collected vapor into an intake passage. The supercharger includes a compressor. The evaporated fuel processing apparatus comprises a purge passage through which the vapor is purged from the canister into the intake passage upstream of the compressor, a second purge passage through which the vapor is purged from the canister into a surge tank, two electromagnetic valves which are operated to open and close the two purge passage, various sensors which detect an operating condition of the engine, and an electronic control unit (ECU) which controls the electromagnetic valves respectively on the basis of values detected by the sensors.
