ABSTRACT:
A vaporized fuel control apparatus for an internal combustion engine. Fuel vapor formed in the fuel tank during the refuelling period is adsorbed to a refuelling canister and fuel vapor formed in the fuel tank during the engine running period is adsorbed to a running canister. The canisters are controlled in a manner that the amount of the fuel vapor discharged into the intake system of the engine from the refuelling canister is smaller than that of the running canister.
