A charcoal canister is part of the evaporative emission control (EVAP) system in many modern automobiles, which is designed to keep gasoline from evaporating into the atmosphere.
As part of the EVAP system, the charcoal canister is generally located somewhere between the fuel tank and the intake. They can often be found in the engine compartment and may be identified by the line that connects them to the fuel tank. Rather than venting a gas tank to the atmosphere, an EVAP system can allow fumes to flow into a canister that contains activated carbon and is therefore capable of adsorbing the fuel vapor. By containing fuel vapors that would otherwise be vented to the atmosphere, the charcoal canister can have a positive environmental impact. Rather than being vented to the atmosphere or absorbed and disposed of, the fuel vapors can be reintroduced to the fuel system and burnt. Rather than venting a gas tank to the atmosphere, an EVAP system can allow fumes to flow into a canister that contains activated carbon and is therefore capable of adsorbing the fuel vapor. Charcoal Canister. In order to prevent fuel vapors from escaping into the atmosphere, a brick of charcoal inside the charcoal canister collects the vapors and later purges them so they can burn in the combustion process. Symptoms of Wear or Failure. 1  Check Engine Light may illuminate. 2  Fuel tank may be hard to fill.

(mechanical engineering). In an evaporative control system, a container filled with activated charcoal that traps gasoline vapors emitted by the fuel system. Also known as canister; carbon canister. 1  Facebook. 2  Twitter. The charcoal canister, which is the vapor-holding gadget for the EVAP System, is a plastic enclosure that contains a large piece of activated charcoal. Charcoal Canister Maintenance. Charcoal canisters do have a tendency of clogging up due to the accumulation of large amounts of dust and impurities from the air, which reduce the performance efficiency of the canisters. After a certain period of time, the canister will stop functioning and will have to be replaced. Charcoal Canister. A container, usually located in the engine compartment, containing activated charcoal. The charcoal absorbs or traps vapors from a vehicle's sealed fuel system, generally when the engine is turned off. This is a basic component of evaporative emissions control systems The charcoal canister was developed with this goal in mind. It is a vapor holding device, used for the evaporative control system (EVAP) that captures any raw fuel evaporating from the fuel storage system, like the fuel tank or the fuel cap, of a motor vehicle. Charcoal Canister Maintenance. Charcoal canisters do have a tendency of clogging up due to the accumulation of large amounts of dust and impurities from the air, which reduce the performance efficiency of the canisters. After a certain period of time, the canister will stop functioning and will have to be replaced. The charcoal canister traps and absorbs fuel vapors from the fuel tank and the carburetor of a motor vehicle when the engine is not running. When the engine is running, the fuel vapors in the canister are absorbed through a vacuum hose into the intake manifold and put back into the system. Charcoal Canister Maintenance. Charcoal canisters do have a tendency of clogging up due to the accumulation of large amounts of dust and impurities from the air, which reduce the performance efficiency of the canisters. After a certain period of time, the canister will stop functioning and will have to be replaced. The evaporative control system functions in such a way that the charcoal canister not only captures and stores but also purges raw fuel vapors. It stores any leaking fuel tank vapors or raw hydrocarbons that would otherwise escape and pollute the atmosphere. Charcoal Canister Maintenance. Charcoal canisters do have a tendency of clogging up due to the accumulation of large amounts of dust and impurities from the air, which reduce the performance efficiency of the canisters. After a certain period of time, the canister will stop functioning and will have to be replaced.
