1 Answers
Mercedes 271 activated carbon canister is normally installed above the right rear or left rear floor panel, while the solenoid valve is usually located near the throttle body, functioning as a three-way valve. Introduction to carbon canister purge solenoid valve: The carbon canister purge solenoid valve is an automotive component designed 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 vapors into the intake manifold for combustion in the engine. Working principle of carbon canister purge solenoid valve: Due to the sealed nature of fuel tanks, 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 off, the carbon canister stores the mixture of fuel vapors and air in its activated carbon micropores, preventing fuel vapors from escaping into the atmosphere.
