STRUCTURE FOR PREVENTION OF FREEZING OF BREAK-THROUGH GAS IN INLET HEADER Russian patent published in 2019 - IPC F01M13/00 F02M35/10 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in the internal combustion engines. Structure for prevention of freezing of broken gas in inlet manifold includes channel (100) of positive crankcase ventilation (PCV), insulating element (200), nipple (300) of PCV. Inlet manifold has air inlet opening (400). Channel of positive crankcase ventilation (PCV) introduces an interrupted gas. Insulating element has the first side and the second side, which are connected to each other. Insulating element is inserted into the PCV channel. Nipple of PCV has the first end and the second end, which are connected to each other. PCV nipple is inserted into the insulating element to direct the breakthrough gas. Insulating element includes outer peripheral surface and inner peripheral surface. Outer peripheral surface is in contact with inner circumferential surface of PCV channel. Inner peripheral surface is in contact with outer peripheral surface of nipple of PCV and surrounds peripheral surface of nipple of PCV.

EFFECT: preventing freezing of moisture in the breakthrough gas in the inlet manifold at low ambient temperatures.
