The purge valve, commonly found in a vehicle's evaporative emissions control system, serves to regulate the flow of fuel vapors from the charcoal canister to the engine intake. Its primary purpose is to reduce harmful emissions by ensuring that these vapors are burned in the engine rather than released into the atmosphere. The valve opens and closes based on engine conditions, helping to maintain optimal performance and environmental compliance. Additionally, it plays a role in enhancing fuel efficiency by ensuring proper vapor management.
