Where is the carbon canister located in a car?

[ErinRose]

The carbon canister is positioned between the fuel tank and the engine in a car. Due to variations in vehicle models, the installation location of the carbon canister may differ. Some carbon canisters are cylindrical in shape, while others are rectangular. Some are mounted on the vehicle frame, and others are installed near the engine front cover. However, the carbon canister is always connected between the fuel tank and the engine. Gasoline generates certain pressure and produces some vapor in high-temperature environments. Since the car's fuel tank is designed to be completely sealed, the gasoline vapor cannot escape. This is where the carbon canister comes into play. When the engine is running, the carbon canister solenoid valve opens, connecting the canister's pipeline to the intake manifold. The gasoline vapor produced by the fuel tank is then stored inside. Upon the next engine start, the stored gasoline vapor enters the combustion chamber to participate in combustion, thereby saving fuel and improving fuel efficiency.
