id0116d2101000

• When the engine is stopped, evaporative gas in the fuel tank flows out when the pressure increases and is absorbed by the charcoal canister.
• Evaporative gas that was absorbed by the charcoal canister passes through the solenoid valve together with air introduced from the charcoal canister when the engine is running, and is fed to the engine according to engine operation conditions.
• If the pressure in the fuel tank decreases, air is introduced from the charcoal canister through the rollover valve.
