摘要： A cylinder block (10) includes an inter-bore flow passage (14) between adjacent bores (12). Each inter-bore flow passage (14) is formed by closing an opening-side groove portion (15) continuous from a cylinder block deck face and a bottom-side groove portion (16) with the use of a lid member (20) made of copper, and the lid member (20 is laser-welded to a groove wall face of the opening-side groove portion (15). Before the laser-welding, the lid member (20) has recesses (26) that are interspersed in a direction, in which a laser beam travels, at any one of connected portions at which the lid member (20 is connected to the groove wall face of the opening-side groove portion (15).

摘要： When viewed from the upper face of a cylinder head in which an intake port communicating with a combustion chamber of an internal combustion engine is formed, a starting point of the port is defined as a point of intersection of the streamline of the intake port and an inlet-side opening plane of the intake port as projected on a horizontal plane, and an end point is defined as a point of intersection of the streamline of the port and the center axis of an intake valve as projected on the horizontal plane. The starting point is located closer to the center of the chamber than a straight line that contains the end point and extends in a direction orthogonal to the axis of the crankshaft on the plane, and the streamline of the port projected on the horizontal plane is curved toward the center of the chamber, with respect to a straight line that contains the starting point and extends in a direction orthogonal to the axis of the crankshaft on the plane.

摘要： The invention provides a friction-welded structure assembly, comprising a first workpiece (10B), a second workpiece (10C) and a friction welding connecting part (10A). The lower side of the friction welding connecting part (10A) has a first friction welding junction interface (10H) which is in contact with a surface of the first workpiece (10B) and a second friction welding junction interface (11H) which is in contact with a surface of the second workpiece (10C). The friction welding connecting part (10A) is tightly pressed on both the first workpiece (10B) and the second workpiece (10C) which are positioned to be relatively corresponding and fixed to each other, while being moved under a pressure, so as to heat said first friction welding junction interface (10H) and said second friction welding junction interface (11H), then said friction welding connecting part (10A) is stopped under the pressure, and said first friction welding junction interface (10H) and said second friction welding junction interface (11H) become cool, thereby said first workpiece (10B) and said second workpiece (10C) are welded together to form the friction-welded structure assembly via said friction welding connecting part (10A). Also, The invention relates to a water-cooled internal combustion engine cylinder head using the friction-welded structure assembly described above.
