The Fuel Evaporation - VOGE DS525X 2019 Operation Manual

The fuel evaporation

In case there is malfunction in fuel evaporation system
Refit the fuel evaporation system is not allowed or it may break the fuel emission laws or regulations
broke down and repaired
hose shall be without squeezing
canister through desorption tube
carbon in canister; And when the engine is working
combustion chamber through the desorption tube to combust for preventing the direct emission of fuel
vapor into air which lead to pollution
The desorption is with the function for balancing the air pressure in fuel tank
tank lower than outside
,
Under the cases make sure the pipeline unobstructed
correction installation of dumping valve
crack and make other parts damage
The fuel evaporation control system works as below:
(1) When the fuel heated, then evaporated, and absorbed
through the dumping valve to the canister TANK end;
(2) When the motorcycle inclined over 60︒, the dumping
valve closed, the gasoline failed flow from dumping
valve to canister.
(3) The fresh air flows from the A end to PURGE end of
canister which brings the fuel vapor into throttle valve,
then flow from the air intake tube into engine join the
combustion.
,
each pipeline shall be well connected without gas leakage or block; The rubber
