The Fuel Evaporation - VOGE SR1 Operation Manual

The fuel evaporation

When the fuel evaporation system gets failed, please contact the VOGE service station. Refit on fuel evaporation system
is not allowed, otherwise the emission may not meet the standard. After removal and repair, check the connection of tube
joint, leakage of pipeline, or block; Check the squeeze, crack or damage on rubber hose. The fuel vapor was released into
carbon canister though the desorption tube, when the engine stopped, the activated carbon in the canister absorb the fuel
vapor; When the engine is working, the fuel vapor in the carbon canister releases into combustion chamber through
desorption tube join the combustion, which prevent the fuel vapor get into air directly to be pollution.
The absorbing tube also make the air pressure in fuel tank get balanced, when the air pressure in fuel tank was lower than
air outside, supplement the air pressure through the absorbing tube on carbon canister; In this case, please make sure all
the tube smooth without blocking and squeeze, make sure the correct installation of anti-toppling valve, otherwise the
fuel pump may damage or fuel tank may get distortion even damage other parts.
The fuel evaporation control system works as below:
(1)When the gasoline in fuel tank gets heated, the gas vapor get out,
absorbed after get though the end TANK of carbon canister of dumping valve.
(2)When the motorcycle inclined over 60°, the dumping valve gets closed,
the gasoline failed to flow into carbon canister through dumping valve.
(3)The fresh air flow from end A of carbon cannister to the end PURGE to
bring the gas vapor into throttle valve, then join combustion by getting
though the air inlet tube.
