摘要： PROBLEM TO BE SOLVED: To provide a cylinder block for an internal combustion engine with improved working efficiency, allowing easy machining of a drill passage hole in a wall part between cylinder bores even if the wall part is narrow. SOLUTION: In this cylinder block 12 for the internal combustion engine wherein plural cylinder liners 11 are cast, the wall part between the cylinder bores 13 is formed with the drill passage hole 15. The periphery of each the liner 11 is formed with a groove 16 for enlarging a distance to the hole 15 in the portion of the wall part between the cylinder bores 13, wherein the distance is reduced. The groove 16 is filled with a constituting material of the block 12 to thicken the wall part between the cylinder bores 13 in the filling part. Thereby, even if the wall part is narrow, a problem such as the breaking through of the wall part by a drill when machining the hole 15 is solved.

摘要： PROBLEM TO BE SOLVED: To accurately and easily measure a surface pressure, fluctuating when an actual machine is operated, for evaluating seal performance of a head gasket in an internal combustion engine. SOLUTION: This head gasket 1 with a sensor is constituted by coating a surface of a metal base plate 3 with an insulating film, arranging thereon with a wiring film 8 a sensing part 11 consisting of thin film-state resistor changing an electric resistance value in accordance with a level of pressure, in addition thereon integrally forming a sensor base plate 2 having a structure coating an insulating film and a head gasket of an internal combustion engine to be layered. Accordingly, by the thin film-state resistor assembled just under the head gasket, its acting surface pressure can be measured when an actual machine is operated. Since the surface pressure is in proportion to a cylinder pressure, even its detection can be made by the sensor base plate 2. Additionally, also deflection and a temperature are similarly detected, more accuracy can be also obtained by correcting a surface pressure signal.

摘要： PROBLEM TO BE SOLVED: To provide a metal gasket and a sealing method using the gasket that suitably seals a three faces mating part as well as a gap made due to level difference of the mating part. SOLUTION: The metal gasket 20 comprises an intermediate plate 21, a lower bead plate 23 and an upper bead plate 22. The thickness of each upper and lower plate 22, 23 is 0.2 mm. Among the three plates, only the intermediate plate 21 is arranged overhung up to an internal periphery of a chain pass (opening) and a step part 21a is formed at the entire periphery thereof. Then, a cold curing silicone rubber 24 is applied to the upper and lower surfaces of the step part 21a thicker than the thickness of the bead plates 22 and 23. The bead plates 22, 23 are arranged adjacent to the step part 21a and then half bead parts 22a, 23a that are expanded to a vertical direction are formed.

摘要： PROBLEM TO BE SOLVED: To prevent stress concentration around a through-hole including of a catch so as to increase the durability of a gasket by proving no catches in a core plate in a specified range between cylinder bores in a cylinder gasket constructed by overlapping the core plate having a number of catches and a sheet material. SOLUTION: A cylinder head gasket is constructed in such a manner that a catch 3 is erected in a core plate 2 made of cold rolled steel, sheet materials 4 are superposed in upper and lower sides and a metallic bore grommet 5 is caulked around a cylinder bore. The catch 3 is eliminated in a specified range between cylinder bores or its number is reduced. Alternatively, the pitches of catches 3 formed in the core plate 2 are set larger than those for the other parts in a specified range between cylinder bores. Thus, the through-hole of the core plate 2 formed during forming of the catch 3 is eliminated, stress concentration around the through-hole is prevented, a reduction in the sectional area of the core plate 2 located in the specified range between the cylinder bores of the cylinder gasket is suppressed and the durable strength of the core plate 2 is increased.
