The evaporative emission control system prevents fuel vapors from escaping into the atmosphere. It consists of the following components:
* Fuel tank: The fuel tank stores the vehicle's fuel.
* Fuel cap: The fuel cap seals the fuel tank and prevents fuel vapors from escaping.
* Fuel line: The fuel line carries fuel from the fuel tank to the engine.
* Vapor canister: The vapor canister stores fuel vapors that evaporate from the fuel tank.
* Purge valve: The purge valve opens and allows fuel vapors to flow from the vapor canister to the engine.
* Carbon canister: The carbon canister absorbs fuel vapors and prevents them from escaping into the atmosphere.
* Vent valve: The vent valve opens and allows air to flow into the vapor canister.
