Charcoal/Fuel Vapor Canister

A car charcoal canister is a small, cylindrical container filled with activated charcoal that is designed to capture and store fuel vapors from the vehicle’s fuel tank and fuel system.
Car Charcoal Canisters help to reduce harmful emissions from vehicles by capturing and storing fuel vapors, preventing them from being released into the environment.
Car Charcoal Canisters have been required as part of emissions control systems on cars since the 1970s.
Car Charcoal Canisters are typically located near the fuel tank.
When fuel vapors are produced by the vehicle’s fuel system, they are directed to the charcoal canister. The activated charcoal inside the canister absorbs the vapors, which are then stored until they can be burned off by the vehicle’s engine during normal operation.
