CATCH TANK CONSTRUCTION/OPERATION
• Integrated with the extension manifold (upper) and cannot be disassembled.
• Evaporative gas between the purge solenoid valve and the charcoal canister is liquefied while being
transferred to the extension manifold (upper) due to a decrease in temperature and other factors. The catch
tank holds such liquefied evaporative gas (gasoline).
• Liquefied evaporative gas is held in the catch tank and not supplied to the extension manifold (upper). This
prevents an overly rich air-fuel ratio.

CHARCOAL CANISTER FUNCTION
• A canister filled with activated charcoal that absorbs evaporative gas temporarily.
End Of Sie
CHARCOAL CANISTER CONSTRUCTION/OPERATION
• A charcoal canister contains activated carbon.
End Of Sie
EVAPORATIVE CHAMBER FUNCTION
• Prevents flooding of the charcoal canister hose that opens to the atmosphere.
End Of Sie
EVAPORATIVE CHAMBER CONSTRUCTION/OPERATION
• Installed into the rear crossmember.
• A small section with partitions is located in the evaporative chamber. These partitions protect the charcoal
canister by preventing flooding as atmospheric air enters from the airflow holes.
End Of Sie
FUEL SHUT-OFF VALVE FUNCTION
• The fuel shut-off valve prevents fuel from flowing to the charcoal canister during tight turns or vehicle rollover.
• The fuel shut-off valve releases evaporative gas to the charcoal canister.
• During refueling, it is possible that, due to the built-up pressure caused by evaporative emissions in the fuel
tank, the fuel could overflow. The shut-off valve closes to prevent such a fuel overflow.
