<P>PROBLEM TO BE SOLVED: To provide a blow-by gas reducing device capable of easily improving a separation efficiency of oil mist in an oil separator. <P>SOLUTION: In the blow-by gas reducing device for supplying a blow-by gas to the oil separator 11 via a blow-by gas supplying pipe 12 to return, to an intake pipe 13 of the engine 1, a remaining blow-by gas in which the oil mist has been separated by the oil separator 11, the blow-by gas supplying pipe 12 is formed zigzag or helically to provide a blow-by gas refrigerating structure. Therefore, the refrigerating structure reduces the blow-by gas in temperature to promote oil vapor within the blow-by gas to devolatilize. Accordingly, the oil mist particles enlarge in diameter, thereby improving the separation efficiency of the oil in the oil separator 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
