Mercedes-Benz 271 active carbon canister is normally installed above the right rear or left rear floor panel. The solenoid valve is usually located near the throttle body and is a three-way component. Introduction to the carbon canister solenoid valve: The carbon canister solenoid valve is a device installed in vehicles to reduce air pollution caused by fuel vapor emissions while improving fuel efficiency. When the vehicle starts, the solenoid valve opens to release adsorbed fuel vapor into the intake manifold for engine combustion. Working principle of the carbon canister solenoid valve: Due to the sealed nature of the fuel tank, fuel consumption creates negative pressure inside the tank. Under this negative pressure, gasoline vaporizes more easily than under normal atmospheric pressure. When the engine is turned off, the carbon canister stores the mixture of fuel vapor and air in the micropores of its activated charcoal, preventing fuel vapor from escaping into the atmosphere.
