The functions of the carbon canister purge solenoid valve are as follows: 1. It is a device installed in vehicles to reduce air pollution caused by fuel vapor emissions while improving fuel efficiency. 2. When the vehicle starts, the solenoid valve opens to release the adsorbed fuel vapors into the intake manifold, where they enter the engine for combustion. The carbon canister is the most critical component in this system, responsible for collecting and storing gasoline vapors. The carbon canister installed in the vehicle is actually an assembly. 3. Its housing is generally made of plastic, with the interior filled with activated carbon particles that can adsorb vapors. The top is equipped with a purge control valve to regulate the amount of gasoline vapors and air entering the intake manifold, as well as a filter screen for purifying gasoline vapors.
