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.
