When the canister purge valve is energized, the electromagnetic coil draws in the magnetic core, which presses on the valve. The gasoline in the canister can then be sucked into the intake manifold. When the canister purge valve stops receiving power, the return spring pushes the valve out, which stops the canister purge.
When the engine is stopped, the canister purge valve closes. The valve control corresponds to the canister purge percentage, which varies with engine speed and load.
