Genuine BOSCH Canister purge valve
Part number 0280142310

The Canister Purge Valve is an integral component of a car's evaporative emissions control system. It is responsible for regulating the flow of fuel vapor from the fuel tank to the engine intake manifold. The main purpose of this valve is to prevent the release of harmful fuel vapors into the atmosphere while improving the overall fuel economy of the vehicle.

When the engine is not running, the Canister Purge Valve remains closed to seal off the fuel vapor line and prevent any vapors from escaping. However, when the engine is running, the valve opens to allow the trapped fuel vapor to be drawn into the engine and burned during the combustion process. By effectively recycling these vapors, the Canister Purge Valve helps reduce pollution and promote cleaner air quality.
