In one example, a method includes controlling a duty cycle of a canister purge valve to purge fuel vapors stored in a fuel vapor storage canister to an engine of the vehicle, and adjusting a flow rate at which the fuel vapors are purged to the engine independently of the duty cycle by controlling a magnitude of a voltage supplied to the canister purge valve during the purging.",
