View Product Details & PurchaseWhat is a Canister Purge Valve?
The canister purge valve, also known as the EVAP purge solenoid, is an essential component of your vehicle's evaporative emission control system. This electronically controlled valve regulates the flow of fuel vapors from the charcoal canister to the engine's intake manifold for combustion during optimal conditions.
How It Works:
- Storage Phase: When the engine is off, fuel vapors are captured and stored in the charcoal canister
- Purge Phase: During engine operation, the Engine Control Unit (ECU) sends an electrical signal to open the purge valve
- Combustion Phase: Fuel vapors are drawn into the intake manifold and burned in the combustion chamber
- Regulation: The valve precisely controls vapor flow to maintain proper air-fuel mixture
