Fuel Evaporation Control System

The control valve is closed when the engine is stopped, idling, or at full throttle. Fumes containing evaporated fuel from the tank flow to the charcoal filter where the vaporated fuel is trapped by the activated charcoal.

With the engine running at part throttle, the control valve is open. Fresh air is drawn from the air cleaner through the charcoal filter and into the intake duct at the air-sensor housing. The evaporated fuel is drawn out of the activated charcoal and burnt up in the engine along with the normal air/fuel mixture.
