Automotive Emission Control
In order to comply with increasingly more stringent regulations worldwide, evaporative emissions from gasoline fueled vehicles must be controlled.
Activated carbon-filled canisters are used to adsorb high levels of volatile hydrocarbons in gasoline tank emissions to prevent them from moving into the ambient air. The adsorbed fuel vapors are then desorbed when the car is driven, regenerating the canister. This adsorption/desorption cycle continues for the life of the vehicle.
