Claims

[Claims for Utility Model Registration] The engine block E includes an oil mist separation chamber 21, a crank chamber side passage 25 that communicates the oil mist separation chamber 21 with the crank chamber 6 below the engine block E, and the oil mist separation chamber 21. Room 21
and a valve train chamber side passage 26 communicating with the valve train chamber 10 on the engine block E, and the crank chamber side passage 25 minimizes the cross-sectional area of its opening end ₂₅₁ on the oil mist separation chamber 21 side. At the same time, this opening end ₂₅₁ and the opening end 261 on the oil mist separation chamber 21 side of the valve train chamber side passage ₂₆ are made to conflict with each other, and furthermore, at least a part of the oil mist separation chamber 21 is formed in the engine block E. An oil mist separation device in a blow-by gas extraction device for an engine, characterized in that the oil mist separation device is placed close to a water jacket 33 in which the oil mist is removed. In the oil mist separation device in the blow-by gas extraction device for an engine as described in claim 1 of the utility model registration, a plurality of each of the crank chamber side passages 25 and the valve train chamber side passages 26 are arranged in parallel in the engine block E. , oil mist separation device in engine blow-by gas extraction device. In the oil mist separation device for a blow-by gas extraction device for an engine as set forth in claim 1 of the registered utility model, one surface of the oil mist separation chamber 21 is provided with an opening 22 in the outer wall surface of the engine block E, and this opening 22 is provided in the outer wall surface of the engine block E. An oil mist separation device in a blow-by gas extraction device for an engine, which is closed by a lid plate 24 made of a metal plate fixed to an outer wall surface.
