Abstract
PURPOSE: To prevent a gasket from being affected by local thermal expansion and to improve the seal-up function of the gasket, by providing slits in the peripheral part around exhaust port so that the slits extend in parallel with the meeting surface of a cylinder head on a cylinder block.
CONSTITUTION: Slits 10 are provided in a part around the gathering section 9b of an exhaust port 9 so that the slits extend in parallel with the meeting surface of a cylinder head 6 on a cylinder block 5. The slits 10 are located on the production of the diameter of the gathering section 9b and extend along the total length of the gathering section. The slits 10 are opened into the gathering section and have a width corresponding to the thermal expansion difference between the part around the gathering section 9b and another part distant from the former part. According to this constitution, deformation due to thermal expansion is absorbed in the cylinder head 6 even if the temperature of the part around the exhaust port 9, especially the part around the gathering section 9b liable to take a high temperature, becomes higher than that of another surrounding part distant from the former part. Therefore, a gasket is prevented from being affected by the deformation and the seal-up function of the gasket is improved.
