How Often Should a Car's Charcoal Canister Be Replaced?

[StevenDella]

There is no fixed replacement interval for a car's charcoal canister, and the vehicle's user manual does not specify how often it should be replaced. As long as the charcoal canister is not damaged, there is no need to replace it. Here is more information about the charcoal canister: 1. The charcoal canister is typically installed between the fuel tank and the engine. It uses the adsorption capacity of the internal activated charcoal to absorb and store gasoline vapors from the fuel tank. 2. When the engine starts, the solenoid valve between the charcoal canister and the intake manifold opens according to the ECU's command. At this point, the gasoline vapors in the charcoal canister are drawn into the cylinder along with the air under the vacuum pressure of the intake manifold, participating in combustion. This not only reduces unnecessary emissions but also lowers the engine's fuel consumption.
