How to Tell if the Charcoal Canister is Faulty?

[ArabellaRose]

Symptoms of a faulty charcoal canister include: 1. Weak acceleration - During driving, you may experience uneven acceleration fluctuations. In this case, check whether the air filter at the inlet of the activated charcoal canister is clogged; 2. Difficulty starting or stalling - If the solenoid valve remains closed, gasoline vapor in the charcoal canister will accumulate excessively and eventually overflow, causing waste and environmental pollution; 3. Strong fuel odor - When experiencing jerky acceleration, a noticeable fuel smell inside the vehicle indicates a fault in the charcoal canister system's fuel lines. The charcoal canister is typically installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at normal temperatures. The fuel evaporation emission control system directs these vapors to the combustion process and prevents them from escaping into the atmosphere.
