The purge valve is a part of the Evaporative Emission Control (EVAP) system. It creates a barrier for the fuel vapors and prevents them from escaping into the atmosphere. When enough pressure is accumulated, the purge valve releases the vapors into the engine, burning them up and minimizing the emission output.
