Abstract
A positive crankcase ventilation (PCV) outlet anti-freezing device of an intake manifold of a vehicle engine includes a first guide and a second guide formed adjacent to a PCV outlet within an inlet tube of the intake manifold to block direct contact between fresh air and a PCV gas, thereby preventing condensation and freezing of the PCV gas. The first guide and the second guide also can improve flow distribution of the intake manifold by improving fluidity of the fresh air.
