In an intake valve lift variable engine including: an engine body; a cylinder head; an intake valve which is disposed in the cylinder head and which is controlled to be open and close so as to regulate the amount of intake air; and an intake system having no throttle valve and connected to the cylinder head, blow-by gas is sucked from a crank case of the engine body into a first pump and pressurizingly transferred by the first pump to the side of the intake system, and purge gas from a canister is mixed into the blow-by gas pressurizingly transferred by the first pump. Thus, the blow-by gas and the purge gas are guided to the intake system.
