Title:
A PURGE EJECTOR ASSEMBLY FOR A VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/210125
Kind Code:
A1
Abstract:
A purge ejector assembly (10) for a vehicle comprises a first fluid passage (111), a second fluid passage (115) and a flow shape unit (20); the flow shape unit (20) is disposed within the first fluid passage (111) between the engine flow port (122) and the air channel flow port (112), where the flow shape unit (20) is configured to raise the flow velocity of air flowing in a direction from the engine flow port (122) to the air channel flow port (112) when a first pressure level (P1) is applied to the engine flow port (122), thereby subjecting the second fluid passage (115) to a second pressure level (P2), which is lower than the first pressure level (P1). The purge ejector assembly is capable of controlling the process of emptying the canister of a vehicle fuel system during various engine conditions. With this type of purge ejector assembly, fuel vapours can be efficiently purged from the canister.
