Abstract
A fuel tank vent system includes a carbon canister and an engine fuel system coupled to the carbon canister. Fuel vapor discharged from a fuel tank included in the engine fuel system flows during certain conditions into the carbon canister to encounter charcoal stored in the carbon canister. Hydrocarbon material associated with the discharged fuel vapor is captured by the charcoal and a stream of cleaned vapor is discharged from the carbon canister to the atmosphere.
