Abstract
An evaporated fuel processing device for a forced induction internal combustion engine according to the present invention includes: a first purge path extending from the downstream of a purge control valve to an intake pipe at the downstream of a throttle valve; and a second purge path extending from the downstream of the purge control valve to an ejector provided in a reflux pipe providing communication between the intake pipe at the downstream of a compressor and the intake pipe at the upstream of the compressor. The evaporated fuel processing device switches first control characteristic data for the first purge path and second control characteristic data for the second purge path, when the first purge path and the second purge path are switched.
