Abstract: A continuously variable valve lift device for a vehicle is provided, which includes a drive shaft rotating in association with a crank shaft and having a drive cam formed on an outer periphery thereof, a locker arm shaft provided apart from the drive shaft and having one end that supports a rocker arm rotating and rocking in association with the drive cam, output cams rotatably installed on the drive shaft to interlock with the other end of the rocker arm, and a variable drive part straightly moving the rocker arm shaft in a vertical direction of the rocker arm shaft to vary a valve lift. When a valve is shifted from the high-lift state to the low-lift state, a pumping loss is reduced to improve the fuel consumption ratio. Also, since an advance function is provided, an exhaust-side CVVT can be deleted to greatly reduce the manufacturing cost.

Abstract: An engine includes exhaust manifold integrally formed with a cylinder head. The engine may include an exhaust manifold having at least one single exhaust outlet for exhausting exhaust gas that is exhausted from at least two cylinders that are not adjacent with each other, wherein periods during which exhaust valves are open are not overlapped with each other between the at least two cylinders.The exhaust manifold is integrally formed with the cylinder head such that costs can be reduced. Also, the water jacket is formed between the exhaust passages of the exhaust manifold such that the durability of the turbocharger that is affected by a heat load can be improved.Also, the twin scroll turbocharger is directly connected to the exhaust outlet of the manifold such that the compression ratio of the intake air can be effectively improved. Further, the exhaust passages at which pulsation interference occurs with each other are separately disposed and the exhaust passages at which pulsation interference does not occur are combined together to form a single passage such that the torque is improved at low rpm and the remaining gas is effectively scavenged.
