Evaporative Control System - Engine Off
When the engine is stationary, any pressure increase in the fuel tank due to a rise in
ambient temperature will cause the fuel vapour to pass down via breather pipe A to a
carbon filled evaporative canister which stores the vapour.
Once in the canister, vapour cannot enter the engine because the purge valve is closed.
