FRESH AIR PATH HYDROCARBON TRAP SYSTEM

摘要

A system for minimizing hydrocarbon vapor emissions includes a fuel vapor adsorption canister and a fresh air vent line from the fuel adsorption canister to an ambient environment to vent the fuel vapor adsorption canister. The fresh air vent line includes one or more hydrocarbon trap sections. The one or more hydrocarbon trap sections of the fresh air vent line adsorb hydrocarbon emissions from the fuel vapor adsorption canister to minimize hydrocarbon emissions to the ambient environment.
