Title:
EVAPORATED FUEL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/056833
Kind Code:
A1
Abstract:
In an engine (10) provided with a turbocharger (16), an evaporated fuel processing device (30) is provided with a canister (34) for adsorbing evaporated fuel generated inside a fuel tank (23), and an ejector (50) for generating negative pressure using supercharged air flowing from an intake passage (12) downstream of the turbocharger (16) to the intake passage (12) upstream of the turbocharger (16) so that the evaporated fuel inside the canister (34) is purged by the resulting negative pressure. The ejector (50) has an ejector housing (52) extending in the direction in which the supercharged air is discharged. The ejector housing (52) is welded to a tubular member (48) functioning as a passage wall of the intake passage (12) so that supercharged air is discharged to the intake passage (12) upstream of the turbocharger (16) and the direction in which the supercharged air is discharged is parallel to the air flow direction.
