摘要： To improve the oil separation performance in an oil separation device for an internal combustion engine. The oil separation device (10) comprises a gas liquid separation passage (56) internally defined by a lower wall, an upper wall and a pair of side walls, and extending in a horizontal direction, a gas inlet (54) and a gas outlet (63) provided on either end of the gas liquid separation passage, a plurality of lower partition walls (56H) projecting upward from the lower wall, and a plurality of upper partition walls (56J) projecting downward from the upper wall. The lower partition walls and the upper partition wall are tilted with respective the length wise direction in plan view so as to define a spiral passage. The lower wall is inclined with respect to a horizontal plane such that an upstream part of the lower wall is lower than a downstream part of the lower wall with respect to a direction of the swirl flow.

摘要： A cooling structure for an internal combustion engine includes a spacer. The spacer is fitted inside a water jacket which is formed to surround peripheries of a plurality of cylinder bores arranged one after another on a cylinder row line of a cylinder block of the internal combustion engine. A cooling condition of the cylinder bores is controlled by regulating a flow of cooling water in the water jacket by use of the spacer. A fixing member for fixing the spacer inside the water jacket is provided on an inner wall surface of the spacer facing the cylinder bores.
