The symptoms of a faulty car fuel tank charcoal canister include: a noticeable increase in gasoline odor, sometimes leading to higher fuel consumption or the engine stalling easily at idle. The charcoal canister is typically installed between the fuel tank and the engine. Since gasoline is a highly volatile liquid, the fuel tank often contains vapor at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from escaping into the atmosphere, with the activated charcoal canister storage device playing a crucial role in this process. The charcoal canister is a container filled with activated carbon, which collects gasoline vapors for secondary use. Gasoline is highly volatile, and the pressure inside the fuel tank increases as it evaporates. To prevent potential hazards, early designs often featured the fuel tank cap as a pressure relief valve. When the pressure inside the tank exceeds a certain level, the relief valve opens, releasing gasoline vapors directly into the atmosphere.
