Engine Evaporative Emissions
Evaporative control systems
Vehicles intended for the North American market are equipped with a fuel vapor evaporative control
system, which prevents gasoline fumes from being released into the atmosphere.
The system is comprised of an expansion chamber in the fuel tank, a roll-over valve and the cross
member in front of the fuel tank, and a charcoal canister with built-in vacuum valve. The components
are interconnected by hoses which channel fuel vapor from the gas tank to the charcoal filter where they
are stored until the engine is started and then drawn into the engine fuel induction system.
