Abstract

An evaporative fuel-processing system for an internal combustion engine for a vehicle includes an evaporative fuel-guiding port for guiding evaporative fuel generated from the fuel tank, an adsorbent for adsorbing the evaporative fuel guided from the evaporative fuel-guiding port, an evaporative fuel-discharging port for discharging the evaporative fuel desorbed from the adsorbent, and an air-introducing port for introducing air. The system comprises a first passage for allowing the air-introducing port to communicate with the chassis side frame of the vehicle, and a second passage for allowing the air-introducing port to communicate with the engine room of the vehicle. A first one-way valve is arranged across the first passage, for allowing a flow from the chassis side frame of the vehicle to the air-introducing port, and a second one-way valve means is arranged across the second passage, for allowing a flow from the air-introducing port to the engine room of the vehicle.
