Can the car's charcoal canister be replaced?

[OliveFitz]

Yes, the car's charcoal canister can be replaced. Replacement cycle for the charcoal canister: In fact, there is no fixed replacement cycle for the car's charcoal canister, and the vehicle's user manual does not specify how often the charcoal canister should be replaced. As a car owner, there is no need to replace the charcoal canister as long as it is not damaged. Some 4S shops may recommend replacing the charcoal canister every 40,000 to 60,000 kilometers, but this is only a conservative estimate of the canister's lifespan. Function of the charcoal canister: The activated charcoal canister is usually installed between the fuel tank and the engine. It utilizes the adsorption capacity of the internal activated charcoal to adsorb and store fuel vapors from the fuel tank. When the engine starts, the solenoid valve between the activated charcoal canister and the intake manifold opens according to the ECU's command. At this time, the fuel vapors in the activated charcoal canister are drawn into the cylinder along with the air under the vacuum pressure of the intake pipe to participate in combustion. This not only reduces unnecessary emissions but also lowers the engine's fuel consumption.
