"The purge valve is a mechanically controlled one way valve. When the engine is off, the purge valve is closed. When the engine is started, the vacuum created in the suction port is used to open this one way valve and allow the vapors to go into the inlet port.
The Evaporative emission contrai system EVAP fitted in our motorcycles prevents gasoline vapors from escaping into the atmosphere from the fuel tank.
As soon as the motorcycle is parked after riding or parked under the sun, the hot radiation from the engine / sunlight causes the fuel in the tank to warm up and releases fuel vapors.
The EVAP system prevents these fuel vapors recycled to engine to avoid vapor into the atmosphere and stored in a charcoal canister.
As soon as the engine is started. these vapours are purged from the canister, into the combustion chamber. The system consists of a canister, purge valve, rubber hoses, connectors and a sealed fuel tank cap."
On pourrait en conclure que le joint de réservoir de Fragdegre n'assure plus l'étanchéité du réservoir.
