Is the Fuel Tank Vent Valve the Same as the Charcoal Canister Solenoid?

[Mandy]

The fuel tank vent valve is not the same as the charcoal canister solenoid. Here is an introduction to the charcoal canister: 1. Overview: 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 function of the fuel evaporation emission control system is to direct these vapors into the combustion process and prevent them from escaping into the atmosphere. 2. Operation Process: Due to the adsorption properties of activated carbon, when the car is running or turned off, gasoline vapors from the fuel tank enter the upper part of the charcoal canister through piping, while fresh air enters from the lower part of the canister. 3. Principle: The charcoal canister is actually part of the Evaporative Emission Control System (EVAP), which is designed to prevent fuel vapors from escaping into the atmosphere after the engine is turned off.
