Evaporative Emission Control System prevents fuel vapor

evaporates in the fuel tank, the vapor passes through vent hoses or
tubes to canister filled with charcoal. The canister temporarily holds

into the combustion chambers during certain operating conditions, it
will vacuum into intake manifold.
