Fuel Evaporation - RIEJU AVENTURA 500 Owner's Manual

Fuel evaporation

When the fuel evaporation system fails, please contact RIEJU service shop for maintenance. Do not change the
fuel evaporation system, otherwise it may not meet the requirements of fuel evaporation emission regulations.
After disassembly and maintenance, check whether all pipelines are well connected and whether the pipeline
joints are free of air leakage, blockage, etc; The rubber hose shall be free from extrusion, fracture, damage, etc.
The fuel vapor in the fuel tank is released into the carbon canister through the desorption pipe. When the engine
stops working, the fuel vapor is adsorbed by the activated carbon in the carbon canister; When the engine is
working, the fuel vapor in the carbon canister is released to the engine combustion chamber through the des-
orption pipe to participate in combustion, so as to prevent the fuel vapor from being directly discharged into the
atmosphere and causing environmental pollution.
At the same time, the adsorption pipe also balances the air pressure in the fuel tank. When the air pressure in the
fuel tank is lower than the external atmospheric pressure, the air pressure in the fuel tank can be supplemented
through the carbon canister air pipe and adsorption pipe; Therefore, ensure that all pipelines are unobstruc-
ted, prevent blockage, extrusion and other phenomena, and ensure that the anti tilt valve is installed correctly,
otherwise it may cause damage to the fuel pump or fuel tank, deformation, rupture or other parts.
The fuel evaporation control system works according to the following principles:
