What does a fuel charcoal canister do?
Part of the car’s emissions controls, this charcoal-filled canister’s job is to absorb fuel vapor that would otherwise vent out to the atmosphere, causing pollution. Vapors trapped by the charcoal are released back into the engine through the purge valve and then burned.
Do I need a carbon canister?
The charcoal canister (aka: EVAP canister) is an essential part of the Evaporative Emission Control System (often shortened to “EVAP”). This system helps ensure that dangerous fumes from your gas tank aren’t released into the environment and instead puts them to work powering the engine.

What are the parts of a car carbon canister?
Carbon Canisters are rectangular shaped boxes that sit apart from the fuel tank next to the throttle in most vehicles. There is an input port and an output port, with the two ports side by side. There are three chambers inside the canister, running in sequence from the intake to the outtake.
