ジンの燃焼室構造。A recess is partially provided in the inner wall of the cylinder head facing the upper surface of the piston, and a squish zone with a slight gap between the combustion chamber formed by the recess and the inner wall of the cylinder head and the upper surface of the piston when the piston is at top dead center. In an engine combustion chamber structure in which an intake port is opened on one side of the combustion chamber and the squish zone, and an exhaust port is opened on the other side, a plug hole is opened in the upper surface of the combustion chamber and the plug hole is connected to the plug hole. In addition to arranging a spark plug, a recessed portion of a predetermined shape is provided on the side surface of the combustion chamber at a position close to the spark plug, with the side wall of the combustion chamber, excluding the vicinity of the lower end opening, facing outward. The engine combustion chamber structure is characterized by:
