The oxygen treatment opens up millions of pores between the carbon atoms, resulting in a highly porous charcoal with a very large effective surface area. This makes the charcoal capable of absorbing large quantities of fuel vapor. Once treated the charcoal is known as activated charcoal or carbon.
The Evaporative emissions canister - secondary is not repairable but is replaced if damaged.
