EVAPORATION FUEL PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an evaporation fuel processing system capable of supplying evaporation fuel having the stable concentration to an internal combustion engine when starting the engine. SOLUTION: This evaporation fuel processing system has a fuel tank 21 for storing fuel of the internal combustion engine 1, and an evaporation fuel tank 25 for storing evaporation fuel generated from the fuel tank, and can cut off the inflow into the evaporation fuel tank from an external part when discharging the evaporation fuel from the evaporation fuel tank.
