The function of the carbon canister in a car is to reintroduce absorbed fuel vapors into the intake manifold, thereby achieving fuel savings and environmental protection. The carbon canister is typically installed between the fuel tank and the engine. Since gasoline is a highly volatile liquid, the fuel tank often becomes filled with vapors 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. The carbon canister is part of the gasoline evaporation control system (EVAP), which was introduced to prevent fuel vapors from escaping into the atmosphere after the engine stops running. Since 1995, China has mandated that all newly manufactured vehicles must be equipped with this system.
