Document Type and Number:
WIPO Patent Application WO/2019/054452
Kind Code:
A1
Abstract:
This vaporized fuel processing device for a supercharger-equipped internal combustion engine has a first purge path extending from downstream of a purge control valve to an air suction pipe downstream of a throttle valve, and a second purge path extending from downstream of the purge control valve through an air suction pipe downstream of a compressor and an air suction pipe upstream of the compressor to an ejector provided to reflux piping, the vaporized fuel processing device being such that when a purge path is switched between the first purge path and the second purge path, control characteristics data is switched to first control characteristics data for the first purge path or to control characteristics data for the second purge path.
