Apparatus for processing evaporated fuel

摘要

An apparatus for processing evaporated fuel produced in a fuel tank for a multicylinder engine evenly distributes purged fuel to each cylinder of the engine. The apparatus has a canister 25 for adsorbing the evaporated fuel and a purge pipe 26 for connecting the canister to an intake duct and purging the adsorbed fuel into the intake duct. The purge pipe 26 has purge ports 1 and 2 that are open in the intake duct at different positions involving different velocities of intake air. The purge pipe 26 may have means for adjusting a flow time of purged fuel passing through the purge pipe. The purge ports may be arranged to produce a swirl of purged fuel in the intake air.
