How the Purge Valve works:
It regulates the flow of stored fuel vapors from the charcoal canister to the intake manifold. It also prevents fuel vapors from the fuel tank.

How the Purge Valve doesn't work:
A failed purge valve can allow the engine to draw in raw fuel resulting in a very rich fuel mixture, black smoke from the exhaust, and increased fuel consumption.
