Evaporative Canister

Print

This system is designed to limit gasoline vapor, which normally escapes from the fuel tank and intake manifold, from discharging into the atmosphere. Vapor absorption is accomplished through the use of the charcoal canister, which stores the vapors until they can be removed and burned in the combustion process.
