Abstract: An active canister purge system may include: a canister trapping a fuel vapor generated in a fuel tank; a purge control valve allowing the trapped fuel vapor to be purged from the canister into an intake pipe; a purge pump forcefully pumping the fuel vapor trapped in the canister into the intake pipe; a pressure sensor detecting a pressure at an inlet of the purge control valve; and a controller determining whether the pressure at the inlet of the purge control valve is varied on the basis of a pressure variation in the intake pipe in a non-purging condition to diagnose an open stuck state of the purge control valve.

Abstract: An active canister purge system according to the present disclosure includes a canister that traps fuel vapor generated in a fuel tank, a purge control valve that purges the fuel vapor trapped in the canister to an intake system of an engine, a purge pump disposed downstream of the purge control valve, a differential pressure measurement device that measures a differential pressure of the purge control valve, and a controller that determines a target purge flow rate of the fuel vapor trapped in the canister, sets a target differential pressure corresponding to the target purge flow rate, and adjusts an RPM of the purge pump such that an actual differential pressure of the purge control valve, which is measured by the differential pressure measurement device, reaches the target differential pressure.
