STRUCTURE FOR PREVENTING FREEZING OF BLOW-BY GAS IN INTAKE MANIFOLD
First Claim
1. A structure for preventing freezing of a blow-by gas in an intake manifold having a new air inlet through which new air is introduced from outside, comprising:
- a positive crankcase ventilation (PCV) channel into which the blow-by gas is introduced;
an insulating member having a first side and a second side that communicate with each other, wherein the insulating member is inserted into the PCV channel; and
a PCV nipple having a first end and a second end that communicate with each other, wherein the PCV nipple is inserted into the insulating member to guide the blow-by gas,wherein the insulating member includes an outer peripheral surface in contact with an inner peripheral surface of the PCV channel and an inner peripheral surface in contact with an outer peripheral surface of the PCV nipple to surround the peripheral surface of the PCV nipple.

Abstract
The present disclosure relates to a structure for preventing freezing of moisture contents within a blow-by gas in an intake manifold, capable of preventing the blow-by gas introduced into the manifold from freezing even under a low temperature environment. The structure includes a positive crankcase ventilation (PCV) channel into which the blow-by gas is introduced, an insulating member having a first side and a second side that communicate with each other and inserted into the PCV channel, and a PCV nipple having a first end and a second end that communicate with each other and inserted into the insulating member to guide the blow-by gas. The insulating member includes an outer peripheral surface in contact with an inner peripheral surface of the PCV channel and an inner peripheral surface in contact with an outer peripheral surface of the PCV nipple to surround the peripheral surface of the PCV nipple.
