Abstract
An evaporation fuel purge system includes: a fuel tank; a canister that absorbs and desorbs evaporation fuel emitted from the fuel tank; an intake passage for an internal combustion engine in which the evaporation fuel desorbed from the canister is mixed with fuel for combustion; a purge passage that connects the canister to the intake passage; an ejector device disposed in the purge passage; and a fluid drive device. The ejector device has a nozzle part that accelerates external fluid. The fluid drive device sends outside air corresponding to the external fluid to flow into the nozzle part.
