...Swirl II, 26...Concave. -Amendment November 26, 1980 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Claims A cylinder block having a cylinder hole, a piston slidably housed in the cylinder hole, and a cylinder head fixed to the upper end of the cylinder block and defining a combustion chamber together with the cylinder block and piston. , an intake port formed in the cylinder head to supply air into the combustion chamber, a recess formed in the cylinder head that opens toward the combustion chamber, and an ignition valve installed in the cylinder head so that the electrode is located in this recess. In an internal combustion engine having a plug, in which gas supplied from the intake port forms a swirl in the combustion chamber, the recess is formed at a position near the center of the combustion chamber, which is a low flow velocity part of the swirl. An internal combustion engine surface characterized in that the recess is formed to open toward a combustion chamber. The brief description of the drawing has been amended as follows. In the third line of page 13 of the specification, "the figure shown" is amended to read "the figure shown, FIGS. 5 and 6, are views showing another embodiment of this invention.""24...Swirl■" on page 13, line 8 of the specification
