An active purge system includes a canister in which a vaporized gas produced in an fuel tank is collected and a purge line that connects the canister to an intake pipe. A purge pump is mounted in the purge line, a purge valve is mounted in the purge line to be positioned between the purge pump and the intake pipe, and a cylinder is connected to the intake pipe. A valve controller changes the operation timing, operation maintenance time, and the operation degree of an intake valve and an exhaust valve disposed at the upper portion of the cylinder. A compression ratio variation device is mounted on a connecting rod and a crankshaft that are connected to a piston to change the top dead center or the bottom dead center of the piston reciprocating in the cylinder.
