ANTI-ICING DEVICE FOR INTAKE MANIFOLD
First Claim
1. An anti-icing device for an intake manifold to prevent moisture from freezing in a blow-by gas that flows from a crankcase of an engine into a plenum chamber of the intake manifold through a gas inlet via a Positive Crankcase Ventilation (PCV) nipple due to a temperature difference with a fresh air supplied into the plenum chamber through a fresh air inlet, the anti-icing device comprising:
- a guide member disposed within the plenum chamber, and for inducing the blow-by gas discharged from the gas inlet toward inside of the plenum chamber in a direction that is away from the fresh air inlet in order to retard a contact with the fresh air.

Abstract
The present disclosure relates to an anti-icing device for an intake manifold for preventing freezing of a blow-by gas flowing from a crankcase of an engine into a plenum chamber of an intake manifold through a gas inlet, and includes a guide member provided inside the plenum chamber, and for inducing the blow-by gas discharged from the gas inlet toward the inside of the plenum chamber that is away from the fresh air inlet, and an engaging means for fixing the guide member to the intake manifold, thus preventing the freezing from occurring and the inlet from clogging by the freezing.
