ABSTRACT:
An evaporative fuel processing system for processing evaporative fuel generated a fuel tank. A canister temporarily stores evaporative fuel generated in the fuel tank. A charge passage connects the fuel tank and the canister. A first purge passage connects the canister and an intake pipe of an internal combustion engine having a turbocharger. A purge control valve is provided in the first purge passage for adjusting a flow rate of gases flowing through the first purge passage. A second purge passage connects a downstream side of the purge control valve of the first purge passage and an upstream side of the turbocharger of the intake pipe. A jet pump is mounted on the second purge passage. A pressurized air supply passage supplies air pressurized by the turbocharger to the jet pump. The jet pump includes a nozzle for discharging the pressurized air supplied through the pressurized air supply passage.
