Abstract: A dual purge device for a vehicle includes a boost pressure introducing port and a fuel evaporation gas introducing port of an ejector that are directly mounted on an ejector mounting part formed on an intake manifold, and a first purge line connecting a purge valve to an intake manifold introducing pipe, respectively, without requiring a hose. By not using the hose or a quick connector, it is possible to simplify a structure of the dual purge device, and to integrally package the intake manifold, the purge valve, and the ejector, thereby simplifying delivery and assembly.

Abstract: An intake manifold is provided and includes a runner that is connected between a plenum and a cylinder head to allow air introduced into the plenum to enter the cylinder head. A dent is formed at the runner such that the dent extends along a channel of the runner while having an inner surface with a protruding shape. The runner has, at an end thereof, an inner surface formed to be flat without being formed with the dent. The inner surface of the runner is connected to the cylinder head.
