Abstract
A vaporized fuel processing apparatus for an engine, which includes an intake passage equipped with a supercharging device and a throttle valve, has an adsorbent canister and a purge passage. The adsorbent canister is adapted to communicate with a fuel tank. The purge passage communicates the adsorbent canister with the intake passage of the engine. The purge passage has in series a purge valve for controlling communication through the purge passage and a purge pump for generating gas flow from the adsorbent canister toward the intake passage. The purge passage includes a sub-passage for communicating the adsorbent canister with the intake passage without passing through the purge pump. The purge passage divides into a first passage connected to the intake passage downstream of the throttle valve and a second passage connected to the intake passage upstream of the supercharging device.
